CV0-004 Practice Question: A cloud administrator is deploying a critical…
A cloud administrator is deploying a critical application that requires the lowest possible latency between compute instances. The instances will be running in a private subnet and must communicate with each other using their private IP addresses. Which of the following deployment configurations would best meet these requirements?
⚠ Common exam trap
Many candidates assume distributing instances across Availability Zones improves performance due to high availability, but for latency-sensitive workloads, the physical proximity of a placement group within a single AZ is the correct choice, not fault tolerance.
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 instances in a placement group within the same Availability Zone.
Deploying instances in a placement group within the same Availability Zone ensures they are physically close together, often in the same rack or cluster, which minimizes network hops and achieves the lowest possible latency. This configuration is ideal for latency-sensitive applications because it leverages non-blocking, high-bandwidth inter-instance communication without traversing additional network infrastructure.
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 instances in different Availability Zones within the same region.
Why it's wrong here
Different AZs introduce higher latency.
- ✗
Deploy instances in the same subnet behind a NAT gateway.
Why it's wrong here
NAT gateway adds latency and is unnecessary for private subnet communication.
- ✗
Deploy instances in different regions and use inter-region peering.
Why it's wrong here
Inter-region latency is high.
- ✓
Deploy instances in a placement group within the same Availability Zone.
Why this is correct
Placement groups ensure low latency and high throughput.
