Implementing Cisco Optical Solutions Engineer (OCSE) — Question 1

In Cisco ACI, if no contract is attached to the EPG, what is the default behavior?

Answer options

• A. All ICMP packets are allowed in inter-EPG communication.
• B. All TCP ports are allowed in inter-EPG communication.
• C. Inter-EPG communication is disabled.
• D. Unidirectional traffic is allowed for all protocols in inter-EPG communication.

Correct answer: D

Explanation

When no contract is attached to an EPG in Cisco ACI, inter-EPG communication defaults to allowing unidirectional traffic for all protocols, which is why option D is correct. Options A and B incorrectly suggest that specific types of traffic are allowed, while option C states that communication is completely disabled, which is not accurate.
