352-001 Question #796: Real Exam Question with Answer & Explanation
The correct answer is A: A failure of a single element causes the entire service to fail. Fate-sharing is a network design property where a single component failure causes all dependent services to fail together.
Question
Which option is a fate-sharing characteristic in regards to network design?
Options
- AA failure of a single element causes the entire service to fail
- BIt protects the network against failures in the distribution layer
- CIt acts as a stateful forwarding device
- DIt provides data sequencing and acknowledgment mechanisms
Explanation
Fate-sharing is a network design property where a single component failure causes all dependent services to fail together.
Common mistakes.
- B. Protecting the network against distribution-layer failures describes a redundancy or high-availability design goal, which is the opposite intent of fate-sharing.
- C. Acting as a stateful forwarding device describes a firewall or session-aware network function, unrelated to fate-sharing.
- D. Data sequencing and acknowledgment mechanisms describe TCP transport-layer behavior, not a network design fate-sharing characteristic.
