350-401 Question #827: Real Exam Question with Answer & Explanation
The correct answer is A: Static default routes. First-hop redundancy protocols (FHRP) overcome the limitations of a single point of failure introduced by static default routes and a computer having only one default gateway.
Question
In a resilient network topology, first-hop redundancy protocols (FHRP) overcome the limitations of which of the following? (Choose two.)
Options
- AStatic default routes
- BLink-state routing protocols
- CVector-based routing protocols
- DA computer with only one default gateway
Explanation
First-hop redundancy protocols (FHRP) overcome the limitations of a single point of failure introduced by static default routes and a computer having only one default gateway.
Common mistakes.
- B. Link-state routing protocols like OSPF are used by routers to dynamically learn network topology and routes, but they do not provide first-hop redundancy for end-user devices.
- C. Vector-based routing protocols like RIP or EIGRP are also dynamic routing protocols used by routers, not designed to solve the first-hop redundancy problem for client devices.
Concept tested. FHRP benefits and limitations overcome
