Question
Refer to the exhibit. Routers CE1 and CE2 support users in different locations, but the users require Layer 2 to operate within the company intranet. A pseudowire is configured between CE1 and CE2 to support these Layer 2 services. The connection is occasionally unstable, so an engineer has been asked to monitor it periodically. How should the engineer verify connectivity between sites over the Layer 2 connection?
Exhibit
Options
- AEnable SNMP to send traps that verify traffic movement between sites.
- BImplement a graceful restart to verify that routes are shared between sites.
- CConfigure NetFlow to monitor the control plane and confirm that traffic is passing.
- DUse MPLS OAM to perform an LSP traceroute over the connection.

Explanation
MPLS OAM (Operations, Administration, and Maintenance): - MPLS OAM provides tools for monitoring and troubleshooting MPLS networks. - The LSP traceroute feature enables verification of connectivity along the Label Switched Path (LSP) used by the pseudowire. This ensures the path is functional and traffic can traverse the Layer 2 connection. Why MPLS OAM for this scenario? - A pseudowire uses MPLS to carry Layer 2 traffic over the core. MPLS OAM tools are specifically designed for troubleshooting and validating MPLS paths. - The LSP traceroute will confirm the integrity of the MPLS path and detect any issues between
