Cisco 600-660 DCACIA Exam Questions

Question 6 of 31

Refer to the exhibit. Which three actions should be taken to implement the vPC in the Cisco ACI fabric? (Choose three.)

Select a common vPC interface policy group

Select individual interface profiles

Select common interface profiles

Select individual switch profiles

Select common switch profiles

Correct Answer: A, C, E

To implement vPC in the Cisco ACI fabric, you need to select a common vPC interface policy group, common interface profiles, and common switch profiles. The common vPC interface policy group ensures consistency in the vPC configuration across interfaces. Common interface profiles allow the same configuration to apply to multiple interfaces, reducing the risk of configuration errors. Common switch profiles ensure that the switches participating in the vPC have the same baseline configuration. Individual profiles are not required for this implementation because vPC needs consistency across interfaces and switches.

Question 7 of 31

Which action should be taken in Cisco ACI to reassign a unique globally scoped pcTag to an EPG that provides a global contract?

Configure subnets that are treated as virtual IP

Configure subnets that advertise externally

Configure subnets that are shared between VRFs

Configure subnets that are private to VRF

Correct Answer: C

To reassign a unique globally scoped pcTag to an Endpoint Group (EPG) that provides a global contract in Cisco ACI, you should configure subnets that are shared between Virtual Routing and Forwarding instances (VRFs). This action is necessary because sharing subnets between VRFs allows for route leaking, which is essential for global pcTag assignment, ensuring that the EPG can communicate across different VRFs while maintaining unique globally scoped tags.

Question 8 of 31

Refer to the exhibit. Which two configurations enable inter-VRF communication? (Choose two.)

Set the subnet scope to Shared Between VRFs

Enable Advertise Externally under the subnet scope

Change the contract scope to Tenant

Change the subject scope to VRF

Export the contract and import as a contract interface

Correct Answer: A, C

To enable inter-VRF communication, it is necessary to ensure the appropriate scope for the subnet and the contract. Setting the subnet scope to 'Shared Between VRFs' allows for the subnet to be accessible across different VRFs, facilitating communication between them. Changing the contract scope to 'Tenant' ensures that the contract applies within the entire tenant, thus managing the communication between different VRFs within the same tenant.

Question 9 of 31

Which two actions should be taken to ensure a scalable solution when multiple EPGs in a VRF require unrestricted communication? (Choose two.)

Configure a taboo contract between the EPGs that require unrestricted communication between each other.

Enable Preferred Group Member under the EPG Collection for VRF section.

Set the VRF policy control enforcement preference to Unenforced.

Set the EPGs that require unrestricted communication between each other as preferred group members.

Set the EPGs that require policy enforcement between each other as preferred group members.

Correct Answer: B, D

To ensure a scalable solution when multiple EPGs (Endpoint Groups) in a VRF (Virtual Routing and Forwarding) require unrestricted communication, two actions should be taken. First, enable Preferred Group Member under the EPG Collection for VRF section. This action allows EPGs to communicate directly without contracts, which simplifies the policy model and improves scalability. Second, set the EPGs that require unrestricted communication between each other as preferred group members. This action facilitates direct communication between the specified EPGs without policy enforcement, ensuring efficient and scalable communication.

Question 10 of 31

Refer to the exhibit. An engineer must have communication between EPG1 in VRF1 and External EPG in VRF2. Which three actions should be taken for the defined subnets in the L3Out External EPG to accomplish this goal? (Choose three.)

Enable Shared Route Control Subnet

Enable External Subnets for External EPG

Enable Export Route Control Subnet

Enable Shared Security Import Subnet

Enable Aggregate Shared Routes

Enable Import Route Control Subnet

Correct Answer: A, B, D

To achieve communication between EPG1 in VRF1 and the External EPG in VRF2, the following actions should be taken: Enable Shared Route Control Subnet to share the route information across VRFs, Enable External Subnets for External EPG to classify these subnets as external and make them routable, and Enable Shared Security Import Subnet to allow the import of security-related routes across VRFs. These settings collectively facilitate the inter-VRF communication required in this scenario.
