JNCIP-DC: Juniper Networks Certified Professional – Data Center (2021) — Question 6

You are building a DCI solution and need both a Layer 2 solution and a Later 3 solution for different workloads within your data centers.
What are two reasons why MPLS would be used a transport for this DCI solution? (Choose two.)

Answer options

• A. The fast failover capabilities of MPLS nodes can be accomplished in a recovery time that is equivalent to 50 ms or better.
• B. MPLS allows you to natively runnel your own Layer 2 traffic through the service provided L3VPN.
• C. MPLS allows you to interconnect multiple data centers over a public IP network.
• D. MPLS allows for any-to-any connectivity allowing for both Layer 2 and Layer 3 DCIs.

Correct answer: B, D

Explanation

Option B is correct because MPLS allows for native tunneling of Layer 2 traffic through L3VPN, which is essential for the DCI solution. Option D is also correct since MPLS provides any-to-any connectivity needed for both Layer 2 and Layer 3 applications. Options A and C, while they may describe benefits of MPLS, do not specifically address the requirements for DCI solutions as effectively as B and D do.
