CV0-004 Troubleshooting Practice Question
A global company runs a SaaS application in multiple cloud regions. They use DNS-based global load balancing to route users to the nearest region. Recently, users in Asia are experiencing high latency and timeouts. The administrator checks the health of the Asian region's resources and finds everything operational. Latency measurements from a monitoring tool show that traffic from Asian users is being routed to the European region. What should the administrator investigate first?
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 latency-based routing policy
The latency-based routing policy. Since the Asian region's resources are operational but traffic is being routed to Europe, the issue is likely that the latency-based routing policy is misconfigured or not accurately measuring latency from Asian users. This policy uses latency measurements to route users to the closest region; if it's flawed, traffic may be sent to a distant region. Investigate the latency routing policy first. Option B (DNS TTL) affects caching duration, not routing decisions. Option C (geo-location records) is used for geographic routing, not latency-based routing. Option D (load balancer in Asia) is operational, so the problem is at the DNS level, not the load balancer.
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 latency-based routing policy
Why this is correct
Misconfiguration in latency-based routing can send traffic to a farther region.
- ✗
The DNS TTL settings
Why it's wrong here
TTL affects how long DNS responses are cached, not routing decisions.
- ✗
The geo-location records in the DNS provider
Why it's wrong here
Geo-location records are for geographic routing; the issue is with latency-based routing.
- ✗
The load balancer configuration in the Asian region
Why it's wrong here
The Asian load balancer is healthy; the issue is upstream in DNS routing.
