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
✓
Check the Service Connection routing configuration to ensure DNS traffic destined for internal DNS servers is correctly routed across the Service Connection tunnel.
Troubleshooting branch office DNS resolution involves checking DNS server IP configuration in remote network settings, Service Connection routing for DNS traffic, and security rules allowing DNS.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Check the Service Connection routing configuration to ensure DNS traffic destined for internal DNS servers is correctly routed across the Service Connection tunnel.
Why this is correct
If internal DNS queries are not routed over the Service Connection, queries fail to reach the corporate DNS servers.
- ✓
Examine Security Policy rules to ensure that DNS traffic (Port 53 TCP/UDP) is permitted between the branch zone and the Service Connection / internal zones.
Why this is correct
Blocking DNS ports in security policies prevents resolution requests from completing.
- ✗
Verify the GlobalProtect client portal certificate.
Why it's wrong here
GlobalProtect portal certificates apply to mobile users, not site-to-site Remote Network DNS resolution.
- ✗
Check the WildFire threat prevention subscription license key.
Why it's wrong here
WildFire subscription status has no impact on DNS packet forwarding or resolution.
- ✓
Verify that the primary and secondary DNS server IP addresses are correctly configured in the Remote Network settings in Panorama.
Why this is correct
Branch networks rely on configured DNS server addresses to forward client queries.
