CV0-004 Practice Question: A cloud administrator needs to deploy a new…
A cloud administrator needs to deploy a new application that requires a static IP address. The administrator is using a cloud provider that allows the reservation of elastic IP addresses. Which deployment step should be taken to ensure the IP address is not lost when the resource is stopped?
⚠ Common exam trap
CompTIA often tests the distinction between ephemeral public IPs (which are lost on stop/start) and elastic/reserved IPs (which persist), and the trap here is that candidates may confuse a static private IP (Option C) with a static public IP, or think DNS alone (Option D) can prevent IP loss.

Correct answer & explanation
✓
Allocate an elastic IP address and associate it with the resource.
Elastic IP addresses are static public IPv4 addresses that you can allocate to your account and associate with a resource. When you associate an elastic IP with an instance, it persists even if the instance is stopped, because the IP is reserved in your account until you explicitly release it. This ensures the IP address is not lost when the resource is stopped, unlike ephemeral public IPs that change on stop/start.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Configure the instance to obtain an IP via DHCP.
Why it's wrong here
DHCP assigns ephemeral IPs.
- ✓
Allocate an elastic IP address and associate it with the resource.
Why this is correct
Elastic IPs are static and persist independent of instance state.
- ✗
Assign a private IP address from a reserved range.
Why it's wrong here
Private IPs are not static for public access.
- ✗
Set up an external DNS service to point to the public IP.
Why it's wrong here
DNS does not reserve the IP itself.
