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?
⚠ Common exam trap
The trap is blaming DNS TTL or geo-location records when the observed behavior — healthy target region but wrong routing — specifically implicates the latency-based routing policy's measurements or configuration.
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 symptom — Asian users being routed to the European region despite healthy Asian resources — points directly to a misconfigured or misbehaving latency-based routing policy. Latency-based routing relies on measured latency between the user's resolver and each regional endpoint, so if the policy is misconfigured or the measurements are stale, traffic will be sent to the wrong region.
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
Latency-based routing selects the region with the lowest measured latency, so a misconfigured or stale policy would explain Asian users being sent to Europe despite healthy Asian resources. Investigating this policy first satisfies the stem's routing anomaly, since resource health and DNS resolution are already confirmed working.
- ✗
The DNS TTL settings
Why it's wrong here
TTL settings govern how long resolvers cache records; they cannot cause Asian users to be routed to Europe, only delay propagation of a fix. It is tempting because stale cached records can mask DNS changes, and TTL tuning is the correct focus when updates propagate too slowly.
- ✗
The geo-location records in the DNS provider
Why it's wrong here
Geo-location records map client IPs to regions; if they misclassify Asian ranges, users are routed to Europe despite healthy Asian resources. It is tempting because geo records do steer traffic, and they would be the right focus when routing is correct but regional mapping is inaccurate.
- ✗
The load balancer configuration in the Asian region
Why it's wrong here
The Asian load balancer only distributes traffic already routed to Asia; since users never reach it, its configuration cannot cause European routing. It is tempting because load balancers do influence regional traffic, and it would be correct if Asian users reached Asia but experienced uneven distribution.
