JNCIP-DC: Juniper Networks Certified Professional – Data Center (2022) — Question 29

Which statement is true about a Data Center Interconnect over an IP network?

Answer options

• A. Layer 2 data must traverse a point-to-point link.
• B. Layer 2 data must traverse an MPLS LSP.
• C. Layer 2 data must be encapsulated.
• D. Layer 3 data must be encapsulated.

Correct answer: C

Explanation

The correct answer is C because, in a Data Center Interconnect scenario, Layer 2 data often needs to be encapsulated to be transmitted over an IP network effectively. Options A and B are incorrect as they imply specific transport methods that are not universally required for Layer 2 data in this context. Option D is also incorrect because the question specifically pertains to Layer 2 data, not Layer 3.
