350-501 Question #594: Real Exam Question with Answer & Explanation
The correct answer is B: They support a scalable control plane.. Microsegments in SRv6 architecture provide a hierarchical and compact way to encode multiple segment instructions or network topology information within a single SID, thereby supporting a scalable control plane.
MPLS and Segment Routing
Question
What is the purpose of microsegments in the SRv6 architecture?
Options
- AThey ensure that routers in the path sufficiently examine the indexed mapping tables.
- BThey support a scalable control plane.
- CThey reduce fragmentation as packets traverse the network.
- DThey allow for configuration changes in the SRv6 data plane without requiring the device to reboot.
Explanation
Microsegments in SRv6 architecture provide a hierarchical and compact way to encode multiple segment instructions or network topology information within a single SID, thereby supporting a scalable control plane.
Common mistakes.
- A. Microsegments primarily focus on encoding instructions efficiently within the SID itself, rather than ensuring routers examine indexed mapping tables sufficiently.
- C. Microsegments are concerned with the structure and encoding of SIDs, not directly with reducing fragmentation, which is a network layer issue related to Maximum Transmission Unit (MTU).
- D. While SRv6 aims for operational flexibility, the specific purpose of microsegments is to efficiently encode segment information for scalability, not to facilitate configuration changes without reboots.
