CV0-004 Practice Question: Is migrating a legacy application to a public…
An organization is migrating a legacy application to a public cloud. The application requires a static IP address that does not change after a VM is stopped. Which of the following should the cloud architect use to meet this requirement?
⚠ Common exam trap
CompTIA often tests the distinction between cloud-agnostic terminology and vendor-specific terms (e.g., 'Reserved IP' vs 'Elastic IP'), trapping candidates who pick a correct AWS concept but fail to recognize the generic term required by the exam.
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
✓
Reserved IP address
A reserved IP address is a static, persistent public IP that remains assigned to a VM even when the VM is stopped or deallocated. In public cloud platforms like Azure, a reserved IP (or static IP) is explicitly set to not change across VM lifecycle events, meeting the requirement for a fixed address that survives stop/deallocate operations.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Reserved IP address
Why this is correct
Reserved IPs are static and remain allocated to the account even when the VM is off.
- ✗
Elastic IP address
Why it's wrong here
Elastic IP is a specific term for AWS; not generic enough for a general cloud question.
- ✗
Ephemeral IP address
Why it's wrong here
Ephemeral IPs are released when the VM stops.
- ✗
Floating IP address
Why it's wrong here
Floating IPs are for dynamic reassignment between VMs, not for persistence on stop.
