NEW QUESTION # 12 
Refer to the exhibits. An engineer must redistribute OSPF internal routes into BGP to connect an on-premises network to a cloud provider without introducing extra routes. Which two commands must be configured on router R2? (Choose two.)
- A. redistribute ospf 1
- B. redistribute bgp 100
- C. router bgp 100
- D. redistribute ospf 1 match internal external
- E. router ospf 1
Answer: C,D
Explanation:
To redistribute OSPF internal routes into BGP, the engineer needs to configure two commands on router R2.
The first command is router bgp 100, which enables BGP routing process and specifies the autonomous system number of 100. The second command is redistribute ospf 1 match internal external, which redistributes the routes from OSPF process 1 into BGP, and matches both internal and external OSPF routes. This way, the engineer can avoid introducing extra routes that are not part of OSPF process 1, such as the default route or the connected routes.

NEW QUESTION # 13
Which approach does a centralized internet gateway use to provide connectivity to SaaS applications?
- A. VPN connections are used to provide secure access to SaaS applications from the on-premises infrastructure.
- B. Internet traffic from the on-premises infrastructure is routed through a centralized gateway that provides access controls for SaaS applications.
- C. A cloud-based proxy server routes traffic from the on-premises infrastructure to the SaaS provider data center.
- D. A dedicated, private connection is established between the on-premises infrastructure and the SaaS provider data center using colocation services.
Answer: B
Explanation:
A centralized internet gateway is a network design that routes all internet-bound traffic from the on-premises infrastructure through a single point of egress, typically located at the data center or a regional hub1. This approach allows the enterprise to apply consistent security policies and access controls for SaaS applications, as well as optimize the bandwidth utilization and performance of the WAN links2. A centralized internet gateway can use various technologies to provide connectivity to SaaS applications, such as proxy servers, firewalls, web filters, and WAN optimizers3. However, a cloud-based proxy server (option A) is not a part of the centralized internet gateway, but rather a separate service that can be used to route traffic from the on-premises infrastructure to the SaaS provider data center4. VPN connections (option C) and dedicated, private connections (option D) are also not related to the centralized internet gateway, but rather alternative ways of providing secure and reliable access to SaaS applications from the on-premises infrastructure5. Therefore, the correct answer is option B, which describes the basic function of a centralized internet gateway. References := 1: Designing and Implementing Cloud Connectivity (ENCC) v1.0, Module 1:

NEW QUESTION # 16
A company with multiple branch offices wants a connectivity model to meet its network architecture requirements. The company focuses on ensuring low latency and efficient routing for its critical business applications. Which connectivity model meets these requirements?
- A. fully meshed topology with SD-WAN technology, using dynamic routing and BGP as the routing protocol
- B. star topology with internet-based VPN connections and static routing
- C. hub-and-spoke topology with SD-WAN technology, using dynamic routing and OSPF as the routing protocol
- D. point-to-point topology using dedicated leased lines and static routing
Answer: A
Explanation:
A fully meshed topology with SD-WAN technology, using dynamic routing and BGP as the routing protocol, meets the requirements of the company because it provides the following benefits:
It allows direct and secure connectivity between any two branch offices, without the need for a central hub or intermediary devices12. This reduces the latency and improves the performance of the critical business applications.
It leverages SD-WAN technology to optimize the traffic flow and application quality of service (QoS) across the WAN13. SD-WAN can dynamically select the best path for each application based on the network conditions and policies13. SD-WAN can also provide redundancy, security, and visibility for the WAN13.
It uses dynamic routing and BGP as the routing protocol to exchange routing information and establish connectivity between the branch offices14. BGP is a scalable and flexible protocol that can support multiple address families, such as IPv4 and IPv6, and multiple routing policies, such as local preference and route filtering14. BGP can also enable seamless integration with the cloud service providers (CSPs) and internet service providers (ISPs)14.

NEW QUESTION # 19
Refer to the exhibit.
While troubleshooting an IPsec connection between a Cisco WAN edge router and an Amazon Web Services (AWS) endpoint, a network engineer observes that the security association status is active, but no traffic flows between the devices What is the problem?
- A. wrong ISAKMP policy
- B. identity mismatch
- C. IKE version mismatch
- D. wrong encryption
Answer: B
Explanation:
An identity mismatch occurs when the local and remote identities configured on the IPsec peers do not match.
This can prevent the establishment of an IPsec tunnel or cause traffic to be dropped by the IPsec policy. In this case, the network engineer should verify that the local and remote identities configured on the Cisco WAN edge router and the AWS endpoint match the values expected by each peer. The identities can be an IP address, a fully qualified domain name (FQDN), or a distinguished name (DN). The identities are exchanged during the IKE phase 1 negotiation and are used to authenticate the peers. If the identities do not match, the peers will reject the IKE proposal and the IPsec tunnel will not be established or will be torn down.

NEW QUESTION # 20
An engineer is implementing a highly securemultitierapplication in AWS that includes S3. RDS, and some additional private links. What is critical to keep the traffic safe?
- A. specific routing and bucket policies
- B. EC2 super policies and specific routing policies
- C. VPC peering and bucket policies
- D. gateway load balancers and specific routing policies
Answer: A
Explanation:
A highly secure multitier application in AWS that includes S3, RDS, and some additional private links requires specific routing and bucket policies to keep the traffic safe. The reasons are as follows:
Specific routing policies are needed to ensure that the traffic between the tiers is routed through the private links, which provide secure and low-latency connectivity between AWS services and on-premises resources12. The private links can also prevent the exposure of the data and the application logic to the public internet12.
Bucket policies are needed to control the access to the S3 buckets that store the application data34. Bucket policies can specify the conditions under which the requests are allowed or denied, such as the source IP address, the encryption status, the request time, etc.34. Bucket policies can also enforce encryption in transit and at rest for the data in S334.

An engineer needs to configure enhanced policy-based routing (ePBR) for IPv4 by using Cisco vManage.
Drag and drop the steps from the left onto the order on the right to complete the configuration of the ePBR using the CLI add-on template.
Answer:
Explanation:
Explanation:
Enhanced Policy-Based Routing (ePBR) is used to direct packets that arrive at an interface to a specified next-hop. It is very useful in managing a large number of configured access lists more efficiently. In ePBR, the router drops the traffic packets if the next hop configured in the PBR policy is not reachable. To avoid packet loss in such scenarios, you must configure multiple next hops for each access control entry.
Here are the steps to configure ePBR for IPv4 using Cisco vManage:
Configure an extended ACL: This step involves defining the network or the host. For example, you can permit IPv4 traffic from any source to specific hosts.
Configure a class map that matches the ACL: Class maps match the parameters in the ACLs. For instance, you can create a class map of type traffic and match it with the previously created ACL.
Configure the policy map with the action to set the next hop: Policy maps with ePBR then take detailed actions based on the set statements configured. You can configure an ePBR policy map with the class map and set the next hop.
Apply the service policy on the interface: Finally, you apply the ePBR policy map to the interface. For example, you can apply the policy map to a GigabitEthernet interface.

NEW QUESTION # 25
Refer to the exhibit.
Refer to the exhibits. An engineer troubleshoots a Cisco SD-WAN connectivity issue between an on-premises data center WAN Edge and a public cloud provider WAN Edge. The engineer discovers that BFD is Dapping on vEdge1. What is the problem?
- A. The control plane deleted the BFD session.
- B. The remote Edgedevice failed to respond BFD keepalives.
- C. The remote Edge device has a duplicate IP address.
- D. The remote Edge device BFD is down.
Answer: B
Explanation:
BFD (Bidirectional Forwarding Detection) is a protocol that detects failures in the overlay tunnel between Cisco SD-WAN devices. BFD packets are sent and received periodically by each device to check the liveliness and quality of the connection. If a device does not receive a BFD packet from its peer within a specified timeout interval, itconsiders the peer to be unreachable and reports a BFD down event. This event triggers a control connection state change and a possible route change in the SD-WAN fabric.
In this scenario, the engineer discovers that BFD is flapping on vEdge1, which means that the BFD session between vEdge1 and the remote Edge device is going up and down repeatedly. This indicates a connectivity issue between the two devices, such as network congestion, packet loss, or misconfiguration. The most likely cause of the problem is that the remote Edge device failed to respond BFD keepalives within the timeout interval, which resulted in a BFD timeout event on vEdge1. This event caused vEdge1 to mark the remote Edge device as down and notify the control plane. The control plane then tried to establish a new BFD session with the remote Edge device, which may have succeeded or failed depending on the network condition. This cycle of BFD session creation and deletion caused the BFD flapping on vEdge1.
The other options are less likely to be the cause of the problem. Option A is incorrect because if the remote Edge device BFD was down, vEdge1 would not receive any BFD packets from it and would not flap. Option C is incorrect because if the remote Edge device had a duplicate IP address, vEdge1 would not be able to establish a BFD session with it in the first place. Option D is incorrect because the control plane does not delete the BFD session unless there is a configuration change or a port-hop event on the device.

An engineer must edit the settings of a site-to-site IPsec VPN connection between an on-premises Cisco IOS XE router and Amazon Web Services (AWS). IPsec must be configured to support multiple peers and failover after 120 seconds of idle time on the first entry of the crypto map named Cisco. Drag and drop the commands from the left onto the order on the right.
Answer:
Explanation:
Explanation:
Step 1 = crypto map cisco 1 ipsec-isakmp Step 2 = set peer 192.168.10.1 default Step 3 = set peer
192.168.20.1 Step 4 = set security-association idle-time 120 default
The process of editing the settings of a site-to-site IPsec VPN connection between an on-premises Cisco IOS XE router and Amazon Web Services (AWS), and configuring IPsec to support multiple peers and failover after 120 seconds of idle time on the first entry of the crypto map named Cisco involves several steps123456.
crypto map cisco 1 ipsec-isakmp: This command is used to create a new entry in the crypto map named
"cisco". The "1" is the sequence number of the entry, and "ipsec-isakmp" specifies that the IPSec security associations (SAs) should be established using the Internet Key Exchange (IKE) protocol13.
set peer 192.168.10.1 default: This command is used to specify the IP address of the default peer for the crypto map entry. In this case, the default peer is at IP address 192.168.10.115.
set peer 192.168.20.1: This command is used to add an additional peer to the crypto map entry. In this case, the additional peer is at IP address 192.168.20.1. This allows the IPsec VPN to support multiple peers56.
set security-association idle-time 120 default: This command is used to set the idle time for the security association. If no traffic is detected over the VPN for the specified idle time (in this case, 120 seconds), the security association is deleted, and the VPN connection fails over to the next peer46.
