Quick Answer
The correct choice is a reserved IP address, because it provides a static, persistent public IP that remains assigned to a cloud VM even after the VM is stopped or deallocated. In public cloud platforms like Azure, a reserved IP—often called a static IP address—is explicitly configured to survive lifecycle events such as stop and deallocate, ensuring the legacy application’s fixed address requirement is met. On the CompTIA Cloud+ CV0-004 exam, this concept tests your understanding of cloud networking fundamentals, specifically how reserved IPs differ from ephemeral or dynamic IPs that change on VM restart. A common trap is assuming a dynamic IP will persist; remember that only a reserved IP guarantees the address stays the same across stop/start cycles. Memory tip: “Reserved means retained—even when the VM is resting.”
This CV0-004 practice question tests your understanding of operations and support. 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.
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?
Reserved IP address
Reserved IPs are static and remain allocated to the account even when the VM is off.
Elastic IP address
Why wrong: Elastic IP is a specific term for AWS; not generic enough for a general cloud question.
Ephemeral IP address
Why wrong: Ephemeral IPs are released when the VM stops.
Floating IP address
Why wrong: Floating IPs are for dynamic reassignment between VMs, not for persistence on stop.
Answer choices
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.
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.
Reserved IP address
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
Floating IP address
Why it's wrong here
Floating IPs are for dynamic reassignment between VMs, not for persistence on stop.
Common exam traps
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.
Detailed technical explanation
In cloud networking, a reserved IP is allocated from the cloud provider's public IP pool and remains dedicated to the subscription until explicitly released. For example, in Azure, a reserved IP is a 'Static' public IP address resource that persists even when the associated VM is deallocated, unlike a 'Dynamic' IP which is released on deallocation. This behavior is governed by the cloud provider's IP address management (IPAM) system, which tracks IP assignment state across VM lifecycle events.
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.
