Practice CCNA 3.5 Describe First Hop Redundancy Protocols questions with exam-style scenarios, detailed explanations, and option-by-option rationale for this topic area.
Example question from this objective
Each option is explained, so the reasoning behind the distractors is part of the answer.
Which problem do first hop redundancy protocols solve for endpoint default gateways?
- They provide dynamic DNS resolution when a server fails
- They assign host addresses when DHCP is unavailable
- They aggregate switch links into one EtherChannel
- They prevent a single router failure from removing the subnet's default-gateway service
They provide dynamic DNS resolution when a server fails — DNS resilience is a different service problem.
They assign host addresses when DHCP is unavailable — FHRPs do not allocate endpoint addresses.
They aggregate switch links into one EtherChannel — EtherChannel provides link aggregation, not default-gateway redundancy.
They prevent a single router failure from removing the subnet's default-gateway service — Correct. FHRPs present a resilient virtual gateway backed by multiple routers.
