CV0-004 Practice Question: A cloud administrator is migrating a legacy…
A cloud administrator is migrating a legacy application to a public cloud IaaS environment. The application requires a static IP address for licensing. Which of the following should the administrator configure to meet this requirement?
⚠ Common exam trap
Many candidates confuse 'Elastic IP' (an AWS-specific term) with a generic static IP, or think a NAT gateway or virtual IP can provide a persistent public IP for inbound licensing, when in fact only a reserved/static public IP meets the requirement.
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 public IP
A reserved public IP (also known as a static public IP) ensures the legacy application always has the same public IP address for licensing purposes. In IaaS environments like Azure, this is called a 'reserved IP' or 'static public IP', which persists even after the VM is stopped or deallocated, meeting the licensing requirement.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
NAT gateway
Why it's wrong here
NAT gateway provides outbound connectivity with a shared IP, not static inbound.
- ✗
Virtual IP address
Why it's wrong here
Virtual IP is used for high availability within a network, not public static IP.
- ✓
Reserved public IP
Why this is correct
Reserved public IP provides a static, persistent address for licensing.
- ✗
Elastic IP
Why it's wrong here
Elastic IP is AWS-specific; the general term is reserved public IP.
