NEW QUESTION # 82
A developer is working on a feature for a new application. The changes in the existing branch named
'feat00304' must be integrated into a single commit with the current working primary branch named
'prodapp411926287'. Which git command must be used?

Answer: C
Explanation:
To integrate changes from an existing branch named 'feat00304' into a single commit with the current working primary branch 'prodapp411926287', the git merge --squash command must be used. This command squashes all commits from the feature branch into a single commit before merging.
A: git rebase --merge feat00304 - Incorrect. This command does not perform a squash merge. B. git merge
--squash feat00304 - Correct. This command squashes all commits from 'feat00304' into a single commit and then merges it. C. git push --rebase feat00304 - Incorrect. This command is used for pushing changes and rebasing, not for squashing commits. D. git checkout --squash feat00304 - Incorrect. This command is invalid.

A developer needs to upload a local file by using the REST API. The developer gathers information according to the documentation and sends the request by using the cURL command in the exhibit but gets an error code.
Which action should be followed to get valid response?
- A. change content type as JSON
- B. add the authorization header with the access token
- C. change request method as GET
- D. add a username-password combination to request command
Answer: B
Explanation:
In the provided cURL command, the developer needs to include an authorization header with the access token to authenticate the API request. Without proper authentication, the server will reject the request and return an error code.
Reference: According to the Cisco DevNet Associate documentation, when using REST APIs to upload files, it is essential to include an Authorization header with the access token to ensure the request is authenticated properly.

NEW QUESTION # 89
Which action resolves a 401 error in response to an HTTP GET that is issued to retrieve statement using RESTCONF on a CSR 1000V?
- A. Check the authentication credentials.
- B. Change the HTTP method to PUT.
- C. Check the MIMF types in the HTTP headers.
- D. Change the transport protocol to HTTPS.
Answer: A
Explanation:
A 401 Unauthorized error indicates that the request has not been applied because it lacks valid authentication credentials for the target resource. To resolve this error when making an HTTP GET request to retrieve data using RESTCONF on a CSR 1000V, you need to ensure that the correct authentication credentials (username and password) are provided.

What are two benefits of using VLANs? (Choose two.)
- A. enables the logical grouping of devices that belong to different Layer 2 devices
- B. extends the broadcast domain
- C. allows all network devices to be accessible from any host on the network
- D. limits the devices that can join the network
- E. segments the broadcast domain
Answer: A,E
Explanation:
VLANs (Virtual Local Area Networks) provide multiple benefits, including segmenting the broadcast domain, which reduces unnecessary traffic and improves network performance. They also enable the logical grouping of devices across different physical Layer 2 switches, enhancing network management and security by isolating traffic between different VLANs.

Which two protocols are associated with the control plane on a network device? (Choose two.)
- A. BGP
- B. UDP
- C. OSPF
- D. FTP
- E. SNMP
Answer: A,C
Explanation:
The control plane in a network device is responsible for routing and signaling. Protocols such as BGP (Border Gateway Protocol) and OSPF (Open Shortest Path First) are integral to the control plane.
* BGP (Border Gateway Protocol): BGP is used for exchanging routing information between autonomous systems on the internet, making it a crucial control plane protocol.
* OSPF (Open Shortest Path First): OSPF is an interior gateway protocol used for routing within an autonomous system, also part of the control plane.

NEW QUESTION # 97
Which network device monitors incoming and outgoing traffic and decides whether to allow or block specific traffic based on a defined set of rules?
- A. load balancer
- B. firewall
- C. switch
- D. reverse proxy
Answer: B
Explanation:
A firewall is a network device that monitors incoming and outgoing traffic and decides whether to allow or block specific traffic based on a defined set of rules.
* Function of a Firewall:
* Traffic Monitoring: It continuously monitors all traffic passing through it.
* Rule-Based Filtering: It applies predefined security rules to allow or deny traffic.
* Protection: It protects networks from unauthorized access and cyber threats.
* Comparison with Other Devices:
* Switch: A network device that connects devices within a LAN and uses MAC addresses to forward data to the correct destination.
* Load Balancer: Distributes network or application traffic across multiple servers to ensure no single server becomes overwhelmed.
* Reverse Proxy: A server that sits in front of web servers and forwards client requests to those web servers.
Therefore, a firewall is the correct answer because it specifically monitors and filters network traffic based on security rules.

what is an advantage of a version control system?
- A. ensures that unit tests are written
- B. forces the practice of trunk-based development
- C. prevents over-writing code or configuration files
- D. facilitates resolving conflicts when merging code
Answer: D
Explanation:
A version control system (VCS) is essential for managing changes to source code over time. One significant advantage of a VCS is:
Facilitates resolving conflicts when merging code (Option C):
* Version control systems like Git track changes made by different developers and provide tools to
* manage and merge these changes. When multiple developers work on the same codebase, conflicts can arise if they make changes to the same lines of code. A VCS helps in identifying these conflicts and provides mechanisms to resolve them, ensuring that the final merged code is consistent and error-free.
