SAP-C02 Practice Question: Accelerate Workload Migration and Modernization
A company is migrating a mission-critical application to AWS. The application requires a fixed IP address for whitelisting by external partners. The company plans to use an Application Load Balancer (ALB) to distribute traffic. However, ALB does not support static IP addresses. How can the company meet the requirement for static IP addresses while using the ALB?
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
✓
Use AWS Global Accelerator with the ALB as an endpoint
Using AWS Global Accelerator provides static anycast IP addresses and directs traffic to the ALB, meeting the requirement for fixed IP whitelisting. Option A (replacing with NLB) would avoid the ALB entirely and may not be suitable for application-level traffic. Option C (Route 53 failover) does not provide static IP addresses for whitelisting. Option D (assigning Elastic IP to ALB) is not supported.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Replace the ALB with a Network Load Balancer (NLB) that has Elastic IP addresses
Why it's wrong here
NLB can have static IPs but is not application-aware; the application may be HTTP-based.
- ✓
Use AWS Global Accelerator with the ALB as an endpoint
Why this is correct
Global Accelerator provides static IP addresses and routes traffic to the ALB.
- ✗
Use Amazon Route 53 with a failover routing policy
Why it's wrong here
Route 53 does not provide static IP addresses for whitelisting; it provides DNS resolution.
- ✗
Assign Elastic IP addresses to the ALB
Why it's wrong here
ALB does not support Elastic IP addresses; it uses DNS name.
