Layer 3 services questions often revolved around VRF separation and route distinguisher and target behavior, with one question asking which routes would be visible after import/export policy changes. Brush up on RD versus RT roles, BGP import/export mechanics for MPLS VPNs, and practical examples of route leaking so you can map config lines to routing outcomes.

I passed after focusing on OAM and fault isolation, especially which tools apply at Layer 2 versus Layer 3 and what each output actually proves. The hardest part was choosing the next best troubleshooting step, not recalling acronyms.

OAM questions focused on Y.1731 service health metrics and interpreting CCM, LM, and DM results, a common exam style was an output interpretation where a missing continuity check pointed to a configuration mismatch. Be comfortable with OAM frame types, intervals, and what each counter indicates so you can quickly diagnose service faults in applied questions.

For VPWS, I managed to pass 4A0-104 by drilling the differences between SDP usage, spoke versus mesh behavior, and how endpoints are stitched together. The exam leaned on configuration intent more than raw command syntax.

VPLS items tended to test MAC learning limits and split horizon consequences with multi-homed sites, one item presented a misbehaving topology and asked where loops or blackholes would occur. Understand split-horizon rules, VPLS learning behavior, and alternatives like BGP-based VPLS so you can reason through stateful scenarios rather than memorize commands.

I passed the Nokia Services Architecture exam by spending extra time on VPLS signaling and split horizon behavior since the tricky items hide in small operational nuances. Doing a few end to end service builds on paper made the scenarios click.

A question on Virtual Private Wire Service asked which pseudowire type and encapsulation would preserve CE VLAN tagging across a mixed MPLS core, which required careful reading of the topology. Review pseudowire variants, attachment circuit behaviors, and MTU/encapsulation implications so you can eliminate options by matching CE requirements to VC attributes.
