Designing Cisco Data Center Infrastructure (DCID, legacy) — Question 19

You plan to extend the Layer 2 domain by using OTV in multicast mode. What must you consider?

Answer options

• A. The same site ID must be used on all of the edge devices on all of the sites.
• B. The join interface must run IGMPv3.
• C. The OTV site VLAN must be extended over the overlay.
• D. The site OTV VLAN must be the same on all of the AED routers on all of the sites.

Correct answer: D

Explanation

The correct answer is D because having the same OTV VLAN on all AED routers ensures proper communication and consistency across the sites. Options A and B relate to other configurations but do not address the specific requirement for VLAN consistency. Option C incorrectly implies that the OTV site VLAN is simply extended, which does not guarantee that the VLANs are identical across all sites.
