352-001 Question #801: Real Exam Question with Answer & Explanation
The correct answer is A: standby route processors for SSO in the access switches. Improving availability in a routed access campus design requires hardware-level redundancy at the access layer, including SSO-capable route processors and redundant power supplies.
Question
You are hired to design a solution to improve network availability for users on a campus network with routed access. Which two recommendations should you make in your design proposal? (Choose two)
Options
- Astandby route processors for SSO in the access switches
- Bstandby route processors for SSO in the core routers
- Credundant power supplies in the access routers
- Dstandby route processors for SSO in the distribution routers
- Ereplace copper links between devices with fiber links
Explanation
Improving availability in a routed access campus design requires hardware-level redundancy at the access layer, including SSO-capable route processors and redundant power supplies.
Common mistakes.
- B. SSO in core routers improves core-layer resilience but does not address the access layer, which is where user connections terminate in a routed access model.
- D. SSO in distribution routers improves distribution-layer availability but does not directly protect the access switches that serve end users in a routed access design.
- E. Replacing copper with fiber reduces media-related failures but does not provide the processor or power redundancy needed to maintain routing and availability during hardware faults.
Concept tested. High availability design with SSO in routed access campus
