ClusterXL is Check Point's high-availability and load-sharing solution, which monitors critical components to ensure cluster functionality. PNOTEs (Problem Notifications) are specific conditions or processes monitored by ClusterXL to detect failures or issues that could impact the cluster's operation. When a PNOTE is triggered, ClusterXL may initiate a failover to maintain service continuity.
Option A: Correct. TED (Threat Emulation Daemon) is not monitored as a PNOTE by ClusterXL. TED is part of the Threat Emulation blade, which handles sandboxing and emulation tasks, but it is not a critical cluster component monitored by ClusterXL.
Option B: Incorrect. Policy installation status is monitored as a PNOTE by ClusterXL. If a policy fails to install or becomes corrupted, ClusterXL can detect this as a critical issue and trigger a failover.
Option C: Incorrect. RouteD (Routing Daemon) is monitored as a PNOTE by ClusterXL. Routing issues, such as the failure of dynamic routing protocols, are critical for cluster operations, especially in environments with dynamic routing enabled.
Option D: Incorrect. VPND (VPN Daemon) is monitored as a PNOTE by ClusterXL. VPN functionality is critical in many deployments, and ClusterXL monitors VPND to ensure VPN tunnels remain operational.
Reference:
The Check Point R81.20 ClusterXL Administration Guide details the components monitored by ClusterXL via PNOTEs, including policy installation, routing (RouteD), and VPN (VPND). The CCTE R81.20 course covers ClusterXL troubleshooting, including understanding PNOTEs and their role in failover decisions. While TED is part of Check Point's Threat Prevention suite, it is not listed as a PNOTE in ClusterXL documentation.
