JNCIP-DC: Juniper Networks Certified Professional – Data Center (2023) — Question 6

Which two statements about an over-the-top (OTT) data center interconnect architecture are correct? (Choose two.)

Answer options

• A. For a Layer 2 stretched network between data centers, a full mesh of VXLAN tunnels between leaf switches is required.
• B. IBGP or EBGP is required for the underlay.
• C. Multicast is supported.
• D. OTT is ideal for small and medium data center designs.

Correct answer: A, B

Explanation

Answer A is correct because a full mesh of VXLAN tunnels is needed to maintain Layer 2 connectivity across data centers. Answer B is also correct as IBGP or EBGP is essential for the underlay to facilitate routing. Options C and D are incorrect; multicast is not typically supported in OTT architectures, and OTT designs are generally aimed at larger data center environments rather than small or medium ones.
