CCSP Practice Question: Deploying a critical application on a public…
A company is deploying a critical application on a public cloud IaaS platform. To ensure high availability and disaster recovery, which TWO of the following strategies should the company implement? (Choose two.)
⚠ Common exam trap
ISC2 often tests the distinction between high availability (fault tolerance within a region using multiple AZs) and disaster recovery (cross-region data replication and failover), and the trap is that candidates confuse active-passive in the same AZ (which is not HA) with a valid HA strategy.
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
✓
Deploy the application across multiple availability zones within a region.
Deploying across multiple availability zones (AZs) within a region ensures that if one AZ experiences an outage, the application can continue serving traffic from another AZ, providing high availability. This is a fundamental cloud architecture pattern for fault tolerance, as each AZ is an isolated data center with independent power, cooling, and networking.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Deploy the application across multiple availability zones within a region.
Why this is correct
This provides high availability within a region.
- ✗
Use an active-passive configuration with both instances in the same availability zone.
Why it's wrong here
Both instances in one zone share the same failure domain.
- ✗
Configure the application to run in only one region to simplify management.
Why it's wrong here
A single region is vulnerable to regional outages.
- ✓
Implement automated snapshots and replicate data to a different geographic region.
Why this is correct
This ensures disaster recovery and data durability.
- ✗
Use a single, large virtual machine instance to handle all traffic.
Why it's wrong here
A single instance is a single point of failure.
