Quick Answer
The correct step is to allocate an elastic IP address and associate it with the resource. This works because an elastic IP is a static public IPv4 address reserved in your cloud account until you explicitly release it, meaning it persists independently of the instance’s lifecycle. When you associate it with an instance, the IP remains attached even if the instance is stopped, unlike an ephemeral public IP that is released and reassigned upon stop and start. On the CompTIA Cloud+ CV0-004 exam, this concept tests your understanding of static IP persistence versus dynamic addressing, often appearing in scenario-based questions about high-availability or fixed-endpoint requirements. A common trap is confusing an elastic IP with an auto-assigned public IP—remember that only a manually allocated and associated elastic IP survives a stop. For a quick memory tip, think “allocate, associate, and it will not dissipate.”
This CV0-004 practice question tests your understanding of deployment. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
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?
Configure the instance to obtain an IP via DHCP.
Why wrong: DHCP assigns ephemeral IPs.
Allocate an elastic IP address and associate it with the resource.
Elastic IPs are static and persist independent of instance state.
Assign a private IP address from a reserved range.
Why wrong: Private IPs are not static for public access.
Set up an external DNS service to point to the public IP.
Why wrong: DNS does not reserve the IP itself.

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.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
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.
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.
Related concept
Read the scenario before looking for a memorised answer.
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.
Common exam traps
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.
Detailed technical explanation
Elastic IPs are implemented as a NAT mapping in the cloud provider's edge gateway, decoupling the public IP from the instance's lifecycle. When you stop an instance, the underlying hypervisor may release the network interface, but the elastic IP remains allocated to your account and can be reassociated to the same or a different resource. This is critical for applications that require a fixed endpoint for whitelisting or DNS stability, as ephemeral public IPs are drawn from a shared pool and are released on stop.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the CV0-004 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
