This question-specific review guide is tied to the answer reasoning for a PracticeTestVault item. Use it after you answer the question so the review stays focused on what the prompt actually tested.
What this question is testing
Objective: IP Services
Prompt focus: A network administrator wants several routers to share a virtual IP address that hosts use as their default gateway, so that if the active router fails, a standby router takes over. Which Cisco protocol provides this first-hop redundancy?
Why the correct answer works
HSRP, which provides a virtual gateway with active and standby routers for redundancy
HSRP provides a shared virtual gateway with active and standby routers for first-hop redundancy.
Why the tempting wrong answer fails
The tempting wrong answer usually loses because it skips the key condition, priority, or evidence in the prompt.
Plain-language takeaway
Hot Standby Router Protocol, or HSRP, is a Cisco first-hop redundancy protocol that lets multiple routers share a virtual IP and MAC address, with an active router forwarding traffic and a standby router ready to take over if the active fails. OSPF…
Simple analogy
Think of ip services like following a short checklist: identify the clue, confirm the rule, and then make the move that fits this exact scenario.
How to review it before a retake
- Underline the command word and name what the question is asking before rereading the choices.
- Compare the correct answer against the closest distractor and write the exact detail that separates them.
- Retest this objective with a fresh question without looking at the rationale first.
