Implementing Cisco Service Provider Advanced Routing Solutions (SPRI) — Question 48

An engineer is working to implement segment routing protocol on the customer’s core network. Which step should the engineer take before the segment routing is enabled and is running with BGP?

Answer options

• A. Segment routing must be configured with EIGRP
• B. Segment routing must be configured with ISIS
• C. MPLS must be configured
• D. Explicit-null must be configured for all neighbors

Correct answer: C

Explanation

The correct answer is C because MPLS must be configured for segment routing to function correctly within the network. Options A and B are incorrect as segment routing does not require EIGRP or ISIS configurations. Option D is also incorrect since explicit-null configuration is not a prerequisite for enabling segment routing.
