Question 12

An administrator is planning network changes for an environment where endpoints communicate through a corporate HTTP proxy. To ensure Cortex XDR agents maintain continuous connectivity to the XSIAM tenant, what must the administrator verify regarding the proxy configuration?

Accepted Answer

The proxy must allow outbound HTTPS traffic to XSIAM FQDNs and support websocket connections without SSL inspection. Cortex XDR agents must be configured with the correct proxy settings (either via installer properties or agent settings) and the proxy must allow outbound HTTPS traffic to the required XSIAM FQDNs without SSL decryption interference.

Answer

The proxy server must run a local Broker VM instance to cache agent heartbeat signals

Answer

The proxy must translate all UDP syslog packets into TCP streams before forwarding

Answer

The proxy must perform full SSL decryption on all agent-to-cloud traffic to inspect security payloads

Question 13

During a high-availability planning session for an on-premises Broker VM deployment, an architect considers deploying multiple Broker VMs behind a load balancer to handle syslog collection from thousands of network devices. What is a critical architectural limitation or consideration when placing Broker VMs behind a load balancer for syslog collection?

Accepted Answer

Load balancing TCP or UDP syslog streams requires careful session persistence and source IP retention to ensure parser context is maintained. When configuring UDP syslog load balancing, statefulness and IP persistence must be carefully managed, and TCP syslog requires persistent connections or proper session handling to prevent log interleaving and parsing corruption.

Answer

Broker VMs cannot accept syslog data if they are registered to the same XSIAM tenant token

Answer

Load balancers prevent the Broker VM from communicating with the Cortex XSIAM cloud backend via port 443

Answer

Broker VMs automatically sync local log queues across the load balancer using BGP routing

Question 14
