What is the primary purpose of BGP-LS in a segment routing network?

To carry traffic engineering policies

To distribute prefix SIDs to BGP peers

To establish BGP sessions between SR domains

To advertise link-state topology information to external consumers

How does segment routing traffic engineering (SR-TE) compare to RSVP-TE in terms of path setup?

SR-TE requires per-path signaling like RSVP-TE

SR-TE requires a separate LDP session for each LSP

SR-TE uses a distributed signaling protocol to establish LSPs

SR-TE does not require a signaling protocol to establish an LSP

What is the role of an SRv6 interworking gateway?

To provide firewall services for SRv6 networks

To provide DNS resolution for SRv6 domains

To translate between SRv6 and non-SRv6 networks

To act as a BGP route reflector

What is the primary purpose of TI-LFA in segment routing?

To load-balance traffic across multiple paths

To reduce the number of labels in the stack

To provide fast reroute for link or node failures

A service provider is using a centralized Path Computation Element (PCE) to compute SR-TE paths for its MPLS core. The PCE needs to receive the network topology and SID information from the routers. Which protocol should the routers use to communicate with the PCE?

PCEP only, for both path computation and topology reporting

PCEP with the SR extensions, and BGP-LS for topology and SID reporting

BGP-LS only, for both path computation and topology reporting

NETCONF for path computation and BGP-LS for topology reporting

3.3 Describe Segment Routing 350-501 Practice Questions (Page 3)

Part of the MPLS and Segment Routing domain, which accounts for 20% of the 350-501 exam. Cisco does not publish an official question count, but from its 120-minute exam (~50–80 total, ~10–16 in this domain), expect 3–5 from this objective — we provide 35 practice questions to prepare you well beyond it.
