A service provider is deploying SRv6 in a new part of its network, but it still has legacy MPLS routers that do not support SRv6. The design team needs to enable communication between the SRv6 domain and the legacy MPLS domain. Which component should be deployed at the boundary?

A BGP route reflector to exchange SRv6 routes with MPLS routers

An SRv6 micro-segment (uSID) on the boundary router

An SRv6 locator on the legacy MPLS routers

An SRv6 interworking gateway that translates between SRv6 and MPLS

A service provider is designing an SRv6 service chain that requires traffic to pass through a firewall, then a load balancer, and then a DPI device, all on different nodes. The design team wants to encode this service chain in the SRv6 SID list. Which approach best achieves this?

Use SRv6 micro-segments (uSIDs) for each service function, stacked in the SRH

Use an SRv6 interworking gateway to chain the services

Use SRv6 prefix segments for each node and rely on the node to invoke the service

Use SRv6 adjacency segments for each link between the service nodes

What is the primary use of SRv6 micro-segments?

To replace BGP for inter-domain routing

To represent services or fine-grained paths within a locator

To provide encryption for SRv6 packets

To reduce the number of IPv6 addresses needed

A service provider is running a multi-domain SR-MPLS network. The domains use different IGPs (OSPF in one, IS-IS in the other). The provider wants to deploy SR-TE paths that span both domains, computed by a centralized PCE. The PCE needs to compute an end-to-end path. What is the most efficient way for the PCE to learn the topology and SIDs across both domains?

Use OSPF-TE in both domains to advertise topology to the PCE

Use BGP-LS to collect topology and SIDs from both domains, and use PCEP with SR extensions for path computation

Use IS-IS TE in both domains to advertise topology to the PCE

Manually configure the topology and SIDs on the PCE

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.
