350-501 Architecture Practice Question
A service provider is migrating from LDP to Segment Routing (SR) in the core. They need to support MPLS forwarding without maintaining LDP sessions. Which SR data plane is appropriate?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
SR-MPLS
Segment Routing with MPLS data plane (SR-MPLS) uses IGP to distribute labels, eliminating the need for LDP. SR-MPLS is the direct replacement for LDP in MPLS networks.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
SRv6
Why it's wrong here
SRv6 uses IPv6, not MPLS.
- ✗
LDP over RSVP
Why it's wrong here
LDP is still required.
- ✗
MPLS-TE with RSVP-TE
Why it's wrong here
RSVP-TE is for traffic engineering, not replacing LDP for all labels.
- ✓
SR-MPLS
Why this is correct
Correct. SR-MPLS uses IGP to advertise labels, no LDP needed.
