4A0-M01 Question #27: Real Exam Question with Answer & Explanation
The correct answer is B. The remote PE routers signal the IES spoke SDP Virtual Circuit (VC)-MTU based on the SDP path MTU. See the full explanation below for the reasoning.
Question
Given the diagram shown and the following information: - Configured on the CSA1 router is an ePipe with redundant spoke Service Distribution Points (SDPs) - The spoke SDPs terminate on Internet Enhanced Services (IES) Interfaces configured on each of the two remote Provider Edge (PE) routers. Which statement correctly describes how the remote PEs signal Maximum Transmission Unit (MTU) values for the ePipe spoke terminations?
Options
- AThe remote PE routers signal the default IES service 1514 byte MTU to the CSA1 router
- BThe remote PE routers signal the IES spoke SDP Virtual Circuit (VC)-MTU based on the SDP path MTU
- CThe PE routers set the service MTUs to the lowest negotiated value
- DThe remote PE routers must signal a VC-MTU equal to the ePipe service MTU plus the Ethernet header size
