NEW QUESTION # 21
Which TWO statements are TRUE about Private IP addresses in Oracle Cloud Infrastructure (OCI)?
- A. A private IP can have an optional public IP assigned to it if it resides in a public subnet.
- B. By default, the primary VNIC of an instance in a subnet has one primary private IP address.
- C. Each VNIC can only have one private IP address.
- D. By default, the primary VNIC of an instance in a subnet has one primary private IP address and one secondary private IP address.
Answer: A,B
Explanation:
Explanation
By default, the primary VNIC of an instance in a subnet has one primary private IP address. A private IP can have an optional public IP assigned to it if it resides in a public subnet. The explanation is that a private IP address is an IPv4 address that is assigned to a VNIC and belongs to the CIDR block of the VCN or subnet.
By default, the primary VNIC of an instance in a subnet has one primary private IP address, which is automatically assigned by OCI and cannot be changed. However, you can also assign secondary private IP addresses to a VNIC, either manually or automatically, up to a maximum of 31 per VNIC. A private IP address can have an optional public IP address assigned to it, which allows the instance to communicate with the internet. A public IP address can be either ephemeral or reserved, depending on whether you want to keep it after stopping or terminating the instance. A private IP address can only have a public IP address assigned to it if it resides in a public subnet, which means that the subnet's route table has a route rule that directs traffic to the internet gateway.
NEW QUESTION # 22
You need to set up instance principals so that an application running on an instance can call Oracle Cloud Infrastructure (OCI) public services, without the need to configure user credentials.
A developer in your team has already configured the application built using an OCI SDK to authenticate using the instance principals provider.
Which is NOTa necessary step to complete this set up?
- A. Create a dynamic group with matching rules to specify which instances can make API calls against services.
- B. Create a policy granting permissions to the dynamic group to access services in your compartment or tenancy.
- C. Generate Auth Tokens to enable instances in the dynamic group to authenticate with APIs.
- D. Deploy the application and the SDK to all the instances that belong to the dynamic group.
Answer: C
Explanation:
Generating Auth Tokens to enable instances in the dynamic group to authenticate with APIs is not a necessary step to complete this set up. This is because Auth Tokens are used to authenticate users, not instances, when making API calls to OCI services. Instance principals are a feature that allows instances to authenticate themselves using certificates, without requiring user credentials or Auth Tokens. The other options are necessary steps to complete this set up, as they enable instances in the dynamic group to make API calls against services using instance principals and IAM policies. Reference: [Instance Principals], [Auth Tokens]
NEW QUESTION # 23
You plan to upload a large file (3 TiB) to Oracle Cloud Infrastructure (OCI) Object Storage. You would like to minimize the impact of network failures while uploading, and therefore you decide to use the multipart upload capability.
Which TWO statements are true about performing a multipart upload using the Multipart Upload API?
- A. You do not have to commit the upload after you have uploaded all the object parts.
- B. While a multipart upload is still active, you can keep adding parts as long as the total number is less than 10,000.
- C. You do not need to split the object into parts. Object Storage splits the object into parts and uploads all of the parts automatically.
- D. When you split the object into individual parts, each part can be as large as 50 GiB.
Answer: B,D
Explanation:
While a multipart upload is still active, you can keep adding parts as long as the total number is less than 10,000. When you split the object into individual parts, each part can be as large as 50 GiB. The explanation is that a multipart upload allows you to upload a large object in parts, which can improve performance and reliability. You need to split the object into parts yourself and upload each part separately using the Multipart Upload API. You can add parts to an active multipart upload until you reach the maximum number of 10,000 parts per upload. Each part can range from 10 MiB to 50 GiB in size, except for the last part, which can be any size.
NEW QUESTION # 24
You are a system administrator of your company and you are managing a complex environment consisting of compute instances running Oracle Linux on Oracle Cloud Infrastructure (OCI). It's your task to apply all the latestkernel security updates to all instances.
Which OCI service will allow you to complete this task?
- A. OCI Streaming service
- B. OCI Registry
- C. OCI Security Zones to achieve automatic security updates
- D. OCI Cloud Guard to monitor and install the security updates
- E. OS Management service
Answer: E
Explanation:
Explanation
OS Management service is the OCI service that will allow you to complete this task. OS Management service is a service that helps users automate patching and package management for Oracle Linux and Windows instances in OCI. It can also help users monitor and manage system configuration and compliance across their instances. The other options are not suitable for this task, as they do not provide the functionality of OS Management service. References: [OS Management Service]
NEW QUESTION # 25
Which is NOT a valid Oracle Cloud Infrastructure (OCI) Virtual Cloud Network (VCN) approach?
- A. Ensure not all IP addresses are allocated at once within a VCN or subnet; instead reserve some IP addresses for future use.
- B. Private subnets should ideally have individual route tables to control the flow of traffic within and outside of VCN.
- C. Ensure VCN CIDR prefix overlaps with other VCNs in your tenancy or with your organizations private IP network ranges.
- D. Use OCI tags to tag VCN resources so that all resources follow organizational tagging/naming conventions.
Answer: C
Explanation:
Ensure VCN CIDR prefix overlaps with other VCNs in your tenancy or with your organizations private IP network ranges. The explanation is that a VCN CIDR prefix is the range of IPv4 addresses that can be used within the VCN and its subnets. The VCN CIDR prefix should not overlap with other VCNs in your tenancy or with your organization's private IP network ranges, as this can cause routing conflicts and connectivity issues. You should choose a VCN CIDR prefix that is large enough to accommodate your current and future needs, but not too large to waste IP addresses. You can use any of the private IPv4 address ranges specified in RFC 1918 for your VCN CIDR prefix.
NEW QUESTION # 26
You are a security administrator for your company's Oracle Cloud Infrastructure (OCI) tenancy. Your storage administrator informs you that she cannot associate an encryption key from an existing Vault to a new Object Storage bucket.
What could be a possible reason for this behavior?
- A. The Object Storage bucket policy lacks the necessary Access Control List (ACL).
- B. There is no Identity and Access Management (IAM) policy that allows the Object Storage service to use the key.
- C. The secret for the key was not created beforehand
- D. The storage administrator forgot to select "Encrypt using Oracle managed keys" while creating the bucket.
Answer: B
Explanation:
There is no Identity and Access Management (IAM) policy that allows the Object Storage service to use the key. The explanation is that when you create an Object Storage bucket with encryption using a customer-managed key from Vault, you need to have an IAM policy that allows the Object Storage service to use the key on your behalf. The policy should look like this:
allow service objectstorage-<region> to use key in compartment <compartment-name> where <region> is the region where your bucket resides and <compartment-name> is the compartment where your key resides.
NEW QUESTION # 27
You are responsible for deploying an application on Oracle Cloud Infrastructure (OCI). The application is memoryintensive and performs poorly if enough memory is not available. You have created an instance pool of Linuxcompute instances in OCI to host the application and defined Autoscaling Configuration for the instance pool.
What should you do to ensure that the instance pool autoscales to prevent poor application performance?
- A. Configure the autoscaling policy to monitor memory usage and scale up the number of instances when itmeets the threshold.
- B. Configure the autoscaling policy to monitor CPU usage and scale up the number of instances when it meets the threshold
- C. Install the monitoring agent on all compute instances, which triggers the autoscaling group.
- D. Install OCI SDK on all compute instances and create a script that triggers theautoscaling event if there ishigh memory usage.
Answer: A
NEW QUESTION # 28
You have objects stored in an OCI Object Storage bucket that you want to share with a partner company. You decide to use pre-authenticated requests to grant access to the objects. Which statement is true about preauthenticated requests?
- A. You cannot edit a pre-authenticated request.
- B. Pre-authenticated requests can be used to delete buckets or objects.
- C. You need to provide your OCI credentials to the partner company.
- D. Deleting a pre-authenticated request does not revoke user access to the associated bucket or object.
Answer: A
Explanation:
You cannot edit a pre-authenticated request is a true statement about pre-authenticated requests. Pre-authenticated requests are URLs that allow users to access objects or buckets in OCI Object Storage without requiring additional authentication or authorization. Pre-authenticated requests can be created with an expiration date and time, and can be used for read or write operations. However, once created, pre-authenticated requests cannot be edited, but can only be deleted or extended. The other statements are false about pre-authenticated requests. Reference: [Pre-Authenticated Requests]
NEW QUESTION # 29
What should be created before provisioning an Oracle Cloud Infrastructure (OCI) DB System?
- A. Compute Instance
- B. Virtual Cloud Network
- C. Bucket in Object Storage
- D. Compartment
Answer: B
Explanation:
Explanation
The explanation is that a Virtual Cloud Network (VCN) is a software-defined network that you set up in OCI to connect your cloud resources, such as compute instances and databases. A VCN provides you with complete control over your network environment, including selecting your own IP address range, creating subnets, route tables, gateways, security lists, etc. You need to create a VCN before provisioning an OCI DB System, as you need to specify which subnet in your VCN you want to launch your DB System in.
NEW QUESTION # 30
When creating an Oracle Cloud Infrastructure (OCI) Virtual Cloud Network (VCN) with the VCN wizard, which THREE gateways are created automatically?
- A. Local Peering Gateway
- B. Dynamic Routing Gateway
- C. NAT Gateway
- D. Bastion Host
- E. Internet Gateway
- F. Storage Gateway
- G. Service Gateway
Answer: C,E,G
Explanation:
Internet Gateway, NAT Gateway, and Service Gateway are three gateways that are created automatically when creating a VCN with the VCN wizard. An Internet Gateway allows public traffic between the VCN and the internet. A NAT Gateway allows private traffic from the VCN to access the internet without exposing the VCN resources to incoming internet connections. A Service Gateway allows private traffic from the VCN to access OCI services such as Object Storage, Email Delivery, and Notifications. The other options are not created automatically by the VCN wizard, but can be added manually later if needed. Reference: [VCN Wizard], [Gateways]
NEW QUESTION # 31
You have three compartments: ProjectA, ProjectB, and ProjectC. For each compartment, there is an admin groupset up: A-Admins, B-Admins, and C-Admins.
Each admin group has full access over their respective compartments as shown in the graphic below.
Your organization has set up a tag namespace, EmployeeGroup.Role and all your admin groups are tagged with a value of 'Admin'.
You want to set up a Test compartment for members of the three projects to share. You also need to provideadmin access to all three of your existing admin groups.
Which policy would you write to accomplish this task?
- A. Allow dynamic-group to manage all-resources in compartment Test where request.principal.group.tag.EmployeeGroup.Role='Admin'
- B. Allow group any-group to manage all-resources in compartment Test where request.principal.group.tag.EmployeeGroup.Role='Admin'
- C. Allow all-group to manage all-resources in compartment Test where
request.principal.group.tag.EmployeeGroup.Role='Admin' - D. Allow any-user to manage all-resources in compartment Test where request.principal.group.tag.EmployeeGroup.Role='Admin'
Answer: C
Explanation:
Explanation
Allow all-group to manage all-resources in compartment Test where
request.principal.group.tag.EmployeeGroup.Role='Admin' is the policy that would accomplish this task. This policy grants admin access to all groups that have the tag EmployeeGroup.Role='Admin' in the compartment Test. The other options are not correct, as they use incorrect terms such as dynamic-group, any-group, or any-user. References: [Tag-Based Authorization]
NEW QUESTION # 32
company sells services to photographers where patrons can preview the photos that they want prints for.
To avoid unauthorized copies, the sample photos have lower resolution and are watermarked. The photos are processed after they are uploaded. The process is fast but not immediate. It creates samples and sends them to storage outside of the instances. Which type of instance is ideal for a process like this; short lived and one that keeps the cost low?
- A. On-demand instances
- B. Preemptible instances
- C. Spot instances
- D. Burstable instances
Answer: B
Explanation:
The explanation is that preemptible instances are VM instances that offer lower costs than regular instances but can be reclaimed by OCI at any time due to capacity constraints or after running for a maximum of 24 hours. Preemptible instances are ideal for short-lived and stateless workloads that can tolerate interruptions and do not require guaranteed availability or performance. Preemptible instances are billed by the second at a fixed rate that is lower than regular instances.
NEW QUESTION # 33
Which Oracle Cloud Infrastructure (OCI) Identity and Access Management (IAM) policy is invalid?
- A. Allow any-user to inspect users in tenancy
- B. Allow group A-Developers to create volumes in compartment Project-A
- C. Allow group A-Admins to manage all-resources in compartment Project-A
- D. Allow dynamic-group FrontEnd to manage instance-family in compartment Project-A
Answer: B
Explanation:
Allow group A-Developers to create volumes in compartment Project-A is an invalid IAM policy. This is because create is not a valid verb for volumes. The correct verb for creating volumes is attach. The other options are valid IAM policies that use correct verbs and syntax. Reference: [IAM Policies], [Verbs]
NEW QUESTION # 34
You have a block volume created in the US West (Phoenix) region. You enabled Cross Region Replication for thevolume and selected US West (San Jose) as the destination region. Now, you would like to create a new volumefrom the volume replica in the US West (San Jose) region.
What should you do?
- A. Activate the replica.
- B. Initiate the replica.
- C. Trigger the replica.
- D. No action required. By default, the replica is available as a block volume.
Answer: A
Explanation:
Explanation
The explanation is that when you enable Cross Region Replication for a block volume, Object Storage creates a replica of the volume in another region of your choice. The replica is not available as a block volume until you activate it. To activate a replica, you need to select the replica from the Block Storage console and click Activate Replica. This will create a new block volume from the replica in the destination region.
NEW QUESTION # 35
As a network architect you have been tasked with creating a fully redundant connection from your on-premises data center to your Virtual Cloud Network (VCN) in the us-ashburn-1 region.Which TWO options will accomplish this requirement?
- A. Configure one FastConnect virtual circuit to the us-ashburn-1 region and a Site-to-Site VPN to the usashburn-1 region.
- B. Configure a Site-to-Site VPN from a single on-premises CPE.
- C. Configure two FastConnect virtual circuits to the us-ashburn-1 region and terminate them in diverse hardware on-premises.
- D. Configure one FastConnect virtual circuit to the us-ashburn-1 region and the second FastConnect virtual circuit to the us-phoenix-1 region.
Answer: A,C
Explanation:
Configure two FastConnect virtual circuits to the us-ashburn-1 region and terminate them in diverse hardware on-premises. Configure one FastConnect virtual circuit to the us-ashburn-1 region and a Site-to-Site VPN to the us-ashburn-1 region. The explanation is that FastConnect is a service that provides a private and dedicated connection between your on-premises network and your VCN in OCI. FastConnect offers higher bandwidth, lower latency, and more consistent network performance than public internet connections. To create a fully redundant connection from your on-premises data center to your VCN in the us-ashburn-1 region, you can either configure two FastConnect virtual circuits to the same region and terminate them in diverse hardware on-premises, or configure one FastConnect virtual circuit to the region and a Site-to-Site VPN to the same region as a backup option.
NEW QUESTION # 36
Which of the following statements is true about cloning a volume in the Oracle Cloud Infrastructure (OCI) BlockVolume service?
- A. You need to detach a volume before cloning it.
- B. You can clone a volume to another region.
- C. Creating a clone takes longer than creating a backup of a volume.
- D. You can change the block volume size when cloning a volume.
Answer: D
Explanation:
Explanation
You can change the block volume size when cloning a volume. The explanation is that cloning a volume is a way of creating an exact copy of an existing volume without creating a backup first. Cloning a volume is faster and cheaper than creating a backup and restoring it to a new volume. When you clone a volume, you can change the block volume size, performance, encryption settings, and tags of the new volume. You do not need to detach a volume before cloning it, as cloning does not affect the source volume or its attachments. You cannot clone a volume to another region, as cloning only works within the same region and availability domain. Creating a clone usually takes less time than creating a backup of a volume, as cloning does not involve transferring data to Object Storage.
NEW QUESTION # 37
When defining a query for metric data in Monitoring, which field provides the time window for aggregatingmetric data points plotted on the metric chart?
- A. Dimension
- B. Namespace
- C. Interval
- D. Statistic
Answer: C
Explanation:
Explanation
Interval is the field that provides the time window for aggregating metric data points plotted on the metric chart. Interval is a parameter that specifies how often metric data points are collected and aggregated by the Monitoring service. For example, an interval of 5 minutes means that metric data points are aggregated every 5 minutes and displayed on the chart. The other options are not fields that provide the time window for aggregating metric data points, but rather other parameters that define the metric query. References: [Interval]
NEW QUESTION # 38
You want to create a policy to allow the NetworkAdmins group to manage Virtual Cloud Network (VCN) in compartment C. You want to attach this policy to the tenancy. The compartment hierarchy is shown below.
Which policy statement can be used to accomplish this task?
- A. Allow group NetworkAdmins to manage virtual-network-family in tenancy
- B. Allow group NetworkAdmins to manage virtual-network-family in compartment C
- C. Allow group NetworkAdmins to manage virtual-network-family in compartment B:C
- D. Allow group NetworkAdmins to manage virtual-network-family in compartment A:B:C
Answer: D
Explanation:
Allow group NetworkAdmins to manage virtual-network-family in compartment A:B:C. The explanation is that when you attach a policy to the tenancy, you need to specify the full path of the compartment where you want to grant permissions. In this case, the compartment C is a sub-compartment of compartment B, which is a sub-compartment of compartment A, which is a sub-compartment of the root compartment (tenancy). Therefore, the full path of compartment C is A:B:C. The virtual-network-family resource type includes all the resources related to VCN, such as subnets, route tables, security lists, gateways, etc.
NEW QUESTION # 39
You are in the process of migrating several legacy applications from on-premises to Oracle Cloud Infrastructure (OCI). The current servers are already virtualized. However, you notice that the version of CentOS currentlyrunning does not align with any of the Oracle-provided compute images.How would you migrate your existing virtual server images to OCI?
- A. Export your current image in the QED format and copy to an Object Storagebucket. Import it as a customimage. Select emulated modeto ensure compatibility with legacy drivers.
- B. Export your current image in the VDI format and copy to an Object Storagebucket. Import it as a customimage. Select native modeto ensure the best possible performance.
- C. Export your current image in the VMDK format and copy to an Object Storage bucket. Import it as a custom image. Select native mode to ensure the best possible performance.
- D. Export your current image in the QCOW2 format and copy to an Object Storage bucket. Import it as a custom image. Select emulated mode to ensure compatibility with legacy drivers
Answer: D
Explanation:
Explanation
Export your current image in the QCOW2 format and copy to an Object Storage bucket. Import it as a custom image. Select emulated mode to ensure compatibility with legacy drivers. The explanation is that QCOW2 is one of the supported formats for importing custom images to OCI. Custom images are images that you can create from your own on-premises or cloud servers and use them to launch instances in OCI. To import a custom image, you need to export your current image in a supported format, copy it to an Object Storage bucket, and then import it as a custom image using the OCI console or API. When you import a custom image, you can choose between native mode or emulated mode. Native mode offers better performance but requires compatible drivers and firmware. Emulated mode offers better compatibility but lower performance.

- A. Allow group NetworkAdmins to manage virtual-network-family in tenancy
- B. Allow group NetworkAdmins to manage virtual-network-family in compartment C
- C. Allow group NetworkAdmins to manage virtual-network-family in compartment B:C
- D. Allow group NetworkAdmins to manage virtual-network-family in compartment A:B:C
Answer: D
Explanation:
Explanation
Allow group NetworkAdmins to manage virtual-network-family in compartment A:B:C. The explanation is that when you attach a policy to the tenancy, you need to specify the full path of the compartment where you want to grant permissions. In this case, the compartment C is a sub-compartment of compartment B, which is a sub-compartment of compartment A, which is a sub-compartment of the root compartment (tenancy).
Therefore, the full path of compartment C is A:B:C. The virtual-network-family resource type includes all the resources related to VCN, such as subnets, route tables, security lists, gateways, etc.
