CV0-004 Troubleshooting Practice Question
A company uses a cloud-based load balancer to distribute traffic to web servers. Recently, a new security policy was applied that restricts traffic to certain geographic regions. Users from an allowed region report they cannot access the website. The load balancer status shows health checks are passing. What should the administrator check?
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
✓
The load balancer's access control lists (ACLs)
Geographic restrictions on a load balancer are typically implemented via access control lists (ACLs). Since health checks are passing, the web servers are functional, so the issue lies in the load balancer's ACLs blocking traffic from the allowed region. Option A is wrong: DNS resolution would affect all users similarly, not just those from a specific region. Option B is wrong: SSL certificate issues would generate browser warnings or errors, not complete inaccessibility. Option C is wrong: web server logs are irrelevant as the traffic is not reaching the servers due to the ACL block.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The DNS resolution for the website
Why it's wrong here
DNS would affect all users equally, not just a specific region.
- ✗
The SSL certificate expiration
Why it's wrong here
SSL issues cause certificate errors, not complete blockage.
- ✗
The web server logs for application errors
Why it's wrong here
Web servers are healthy, so application errors are unlikely.
- ✓
The load balancer's access control lists (ACLs)
Why this is correct
ACLs enforce geographic restrictions and could be misconfigured, blocking allowed regions.
