Designing Cisco Enterprise Networks (ENSLD) — Question 185

What is the purpose of a TLOC extension in a Cisco SD-WAN network fabric?

Answer options

• A. to facilitate WAN Edge router redundancy within a site
• B. to identify the physical interface where a WAN Edge router connects to the WAN transport network
• C. to expand the number of colors that are potentially applied to a network transport interface
• D. to aggregate multiple physical Interfaces into a single logical interface

Correct answer: A

Explanation

The correct answer, A, is accurate as TLOC extensions provide redundancy for WAN Edge routers at a site, ensuring continuous connectivity. Option B is incorrect because it describes the function of a TLOC rather than its extension. Option C does not apply, as TLOC extensions do not relate to color expansion. Option D is also wrong, as TLOC extensions do not aggregate interfaces but rather enhance redundancy.
