Implementing Cisco ACI Advanced (DCACIA) — Question 55

An engineer must allow routes learned from one L3Out to be advertised out another L3Out. The engineer does not have an explicit list of all the routes that must be advertised out, however, they know that they are all part of the 10.16.0.0/16 CIDR block. Which attributes must be selected under Ext-EPG to allow the necessary routes to be advertised out?

Answer options

• A. Enable Export Route Control Subnet and enable Aggregate Export
• B. Disable Shared Route Control Subnet and enable Aggregate Shared Routes
• C. Enable Export Route Control Subnet and disable Aggregate Shared Routes
• D. Enable Export Route Control Subnet and enable Shared Route Control Subnet

Correct answer: A

Explanation

The correct choice, A, is necessary because enabling Export Route Control Subnet along with Aggregate Export allows all routes in the specified CIDR block to be advertised. The other options either disable crucial settings or do not provide the necessary exporting capability for the routes in question.
