Refer to the exhibits. An engineer needs to configure a site-to-site IPsec VPN connection between an on premises Cisco IOS XE router and Amazon Web Services (AWS). Which two IP prefixes should be used to configure the AWS routing options? (Choose two.)

• A.30.30.30.0/24
• B.50.50.50.0/30
• C.40.40.40.0/24
• D.30.30.30.0/30
• E.20.20.20.0/24

Refer to the exhibits.

While troubleshooting, a network engineer discovers that the backup path fails between ASBR3 and ASBR4 for traffic between BGP AS6000 and BGP AS6500 when the connection between ASBR1 and ASBR2 goes down. The following configurations were performed on ASBR1:

Which command is missing?

• A.bgp additional-paths select
• B.bgp advertise-best-external
• C.redistribute static
• D.bgp additional-paths Install

Refer to the exhibits. An engineer must redistribute only the 10.0.10.0/24 network into BGP to connect an on-premises network to a public cloud provider. These routes are currently redistributed:

Which command is missing on router R2?

• A.redistribute ospf 1 match external
• B.neighbor 10.0.10.2 remote-as 100
• C.neighbor 10.0.10.0/24 remote-as 100
• D.redistribute ospf 1 match internal

An engineer must use Cisco vManage to configure an SLA class to specify the maximum packet loss, packet latency, and jitter allowed on a connection. Drag and drop the steps from the left onto the order on the right to complete the configuration.

정답:

Explanation:

The process of configuring an SLA class to specify the maximum packet loss, packet latency, and jitter allowed on a connection using Cisco vManage involves several steps12.
Click Configuration, select Policies, and then select Add Policy: This is the first step where you navigate to the Policies section in the Configuration menu of Cisco vManage1.
Click SLA Class and then click New SLA Class List: In this step, you create a new SLA Class List1.
Select Criteria, select Loss, Latency and Jitter, and then click Add: After setting up the SLA Class List, you select the criteria for the SLA class. In this case, the criteria are Loss, Latency, and Jitter1.
Set values for Loss, Latency, Jitter, and App Probe Class: Finally, you set the values for Loss, Latency, Jitter, and App Probe Class1.

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.

정답:

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.
