352-001 Question #130: Real Exam Question with Answer & Explanation
The correct answer is D: Create a multichassis system with the two routers. The question asks for the best redesign to improve availability for two core-site routers, which is addressed by combining them into a single logical multichassis system.
Question
Refer to the exhibit. How would you redesign the network to improve availability of the routers 1A and 1B at the core site?
Exhibit
Options
- AEnable Graceful Restart Helper for OSPF
- BUse link bundles over multiple slots
- CUse APS Ethernet circuits and redundant interfaces
- DCreate a multichassis system with the two routers
Explanation
The question asks for the best redesign to improve availability for two core-site routers, which is addressed by combining them into a single logical multichassis system.
Common mistakes.
- A. Graceful Restart Helper for OSPF only allows OSPF neighbors to maintain forwarding during an OSPF process restart and does not address physical router redundancy or availability.
- B. Link bundles over multiple slots improve link-level bandwidth and redundancy but do not address the availability of the routers themselves as logical or physical devices.
- C. APS (Automatic Protection Switching) Ethernet circuits provide circuit-level protection for specific links but do not improve overall router-level availability at the core site.
Concept tested. Multichassis router redundancy for high availability
