Implementing and Operating Cisco Service Provider Network Core Technologies (SPCOR) — Question 323

An engineer must extend Layer 2 between two campus sites connected through an MPLS backbone that encapsulates Layer 2 and Layer 3 data. Which action must the engineer perform on the routers to accomplish this task?

Answer options

• A. Configure QoS for MPLS and E-ACCESS.
• B. Configure a EtherChannel for E-LAN.
• C. Configure a pseudowire for E-LINE.
• D. Configure Cisco MPLS TE for use with E-TREE.

Correct answer: C

Explanation

The correct action is to configure a pseudowire for E-LINE because it allows for the emulation of a point-to-point connection over an MPLS network, effectively extending Layer 2 connectivity. The other options either pertain to different configurations that do not facilitate Layer 2 extension or involve different services that are not relevant to the task at hand.
