Designing Cisco Data Center Infrastructure (DCID, legacy) — Question 10

In which OTV transport mode must an AED router create multiple copies of each control plan packet?

Answer options

• A. site-to-site
• B. unicast-only
• C. multicast
• D. anycast

Correct answer: C

Explanation

The correct answer is C, multicast, because in this transport mode, the AED router sends out multiple copies of control plane packets to ensure they reach all intended receivers. The other options, such as unicast-only and anycast, do not involve sending multiple copies, and site-to-site does not inherently require multiple transmissions of control packets.
