XDR-Engineer Maintenance And Troubleshooting Practice Question
An administrator wants to ensure high availability and load balancing for log collection using Cortex XDR Broker VMs. Which TWO architectural best practices should be implemented? (Choose two)
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
✓
Configure syslog sources to point to a network load balancer that distributes traffic across multiple Broker VM instances.
Broker VM high availability is achieved by deploying multiple Broker VMs behind a load balancer or configuring multiple syslog forwarders.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Cluster Broker VMs into a single IP address using Windows Failover Clustering.
Why it's wrong here
Broker VMs run on Linux virtual appliances (OVA), not Windows Clustering.
- ✓
Configure syslog sources to point to a network load balancer that distributes traffic across multiple Broker VM instances.
Why this is correct
A network load balancer provides failover and load distribution across multiple Broker VMs.
- ✗
Route all syslog traffic through a single Broker VM to prevent packet loss.
Why it's wrong here
Routing all traffic through a single VM creates a single point of failure and potential performance bottlenecks.
- ✗
Configure active-passive clustering using VRRP directly inside the Broker VM appliance settings.
Why it's wrong here
Broker VMs do not use built-in VRRP clustering; scaling is handled via multiple independent VMs or load balancers.
- ✓
Deploy multiple Broker VMs in the environment to distribute log forwarding loads from large numbers of sources.
Why this is correct
Multiple Broker VMs can share ingestion workloads across different network segments.
