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 local proxy configurations and ensure the agent profile has correct proxy credentials defined if required.
Agent connectivity troubleshooting requires checking outbound HTTPS reachability to the tenant and verifying valid agent proxy or DNS resolution settings.
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 that the Broker VM has direct SSH access to the endpoint.
Why it's wrong here
Broker VMs do not manage or SSH into endpoints.
- ✗
Verify that UDP port 514 is listening locally on the endpoint.
Why it's wrong here
Port 514 is for syslog collection on Broker VMs, not endpoint agent communication.
- ✓
Check local proxy configurations and ensure the agent profile has correct proxy credentials defined if required.
Why this is correct
Proxy misconfigurations are a primary cause of agent disconnection in enterprise networks.
- ✓
Verify that outbound TCP port 443 traffic to the Cortex XDR tenant URL is not blocked by a firewall or security gateway.
Why this is correct
Outbound TCP port 443 is required for agent-to-cloud communication.
- ✗
Verify that inbound TCP port 22 is open on the endpoint for remote management.
Why it's wrong here
Cortex XDR agents do not require inbound SSH (port 22) from the cloud console.
