Implementing Cisco Application Centric Infrastructure (DCACI) — Question 133

A network engineer configures the Cisco ACI fabric to connect to vCenter with these requirements:
• Port groups must be automatically created on the distributed virtual switch.
• Port groups must use the VLAN allocation in the range between 20-30.
• The deployment must optimize the CAM space on the leaf switches.

Which set of actions meets these criteria?

Answer options

• A. Create a dynamic VLAN pool with the VLAN range of 20-30. Create a VMM domain and associate it with the VLAN pool. Create the EPG and associate the domain. Set the deployment immediacy to On Demand.
• B. Create a dynamic VLAN pool with the VLAN range of 20-30. Create a physical domain and associate it with the VLAN pool. Create the EPG and associate the domain. Set the deployment immediacy to On Demand.
• C. Create a static VLAN pool with the VLAN range of 20-30. Create a physical domain and associate it with the VLAN pool. Create the EPG and associate the domain. Set the deployment immediacy to Immediate.
• D. Create a static VLAN pool with the VLAN range of 20-30. Create a VMM domain and associate it with the VLAN pool. Create the EPG and associate the domain. Set the deployment immediacy to Immediate.

Correct answer: A

Explanation

The correct answer is A because it utilizes a dynamic VLAN pool which supports automatic port group creation on the distributed virtual switch and optimizes CAM space. Option B incorrectly uses a physical domain instead of a VMM domain, while options C and D use static VLAN pools which do not meet the requirement for automatic creation of port groups.
