CV0-004 Practice Question: Which TWO design patterns can help a cloud…
Which TWO design patterns can help a cloud architect achieve a Recovery Time Objective (RTO) of less than 5 minutes for a critical application?
⚠ Common exam trap
CompTIA often tests the misconception that warm standby or pilot light can achieve sub-5-minute RTO, but candidates forget that these patterns require manual scaling or provisioning steps that add significant delay, unlike the fully pre-provisioned and automated failover in active-active or hot standby.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Multi-site active-active
Multi-site active-active (B) distributes the application workload across two or more geographically separated sites, with all sites actively serving traffic. If one site fails, traffic is instantly rerouted to the remaining sites via DNS load balancing or global server load balancing (GSLB), enabling sub-5-minute RTO because there is no cold start or failover delay. Hot standby (active/passive) with automatic failover (E) maintains a fully provisioned standby environment that mirrors the primary, with automatic health checks and failover mechanisms (e.g., using AWS Route 53 health checks or Azure Traffic Manager) that can redirect traffic within seconds to minutes, meeting a strict RTO of under 5 minutes.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Warm standby
Why it's wrong here
Warm standby involves promoting a standby environment, which can take several minutes.
- ✓
Multi-site active-active
Why this is correct
Multiple active sites can take over instantly, achieving RTO under 5 minutes.
- ✗
Backup and restore
Why it's wrong here
Backup and restore has an RTO of hours or days.
- ✗
Pilot light
Why it's wrong here
Pilot light requires provisioning additional resources and may exceed 5 minutes.
- ✓
Hot standby (active/passive) with automatic failover
Why this is correct
Hot standby maintains a fully running passive environment that can take over in seconds.
