   How does iQuery contribute to LTM monitoring between BIG-IP systems?

   • AIt synchronizes the configuration of monitors across devices.
   • BIt provides a secure channel for transferring log files between devices.
   • CIt enables devices to notify each other of status changes, such as a node going down.
   • DIt performs active health checks on behalf of the LTM system.

   A company is setting up a sync group for BIG-IP DNS devices in different geographic regions. The administrator has confirmed that NTP is configured and device trust is established. What is the most important network requirement for the sync group to function?

   • AAll devices must have a public IP address.
   • BAll devices must be on the same subnet.
   • CAll devices must be in the same DNS domain.
   • DTCP port 4353 must be open between all devices.

   A company is deploying a sync group for BIG-IP DNS across two sites. The administrator has configured device trust and NTP. However, the sync group is not functioning correctly, and the administrator suspects that the WAN link is dropping iQuery packets. What is the best way to verify this?

   • AReview the virtual server statistics.
   • BUse tcpdump on the management interface to capture iQuery traffic.
   • CCheck the DNS zone transfer logs.
   • DPing the peer device from the management interface.

   A DNS administrator is troubleshooting a sync group that was working but has stopped synchronizing configuration changes. The devices can still ping each other, and device trust is intact. What should the administrator check first?

   • AWhether the virtual servers are configured with the same profiles.
   • BWhether the DNS zone files are correctly signed.
   • CWhether the devices have the same software version.
   • DWhether iQuery traffic is being blocked by a firewall or ACL.

   An organization runs a pair of BIG-IP LTM devices in an active-standby configuration. The standby device is not receiving health-check status updates for the pool members, so it cannot take over cleanly if the active device fails. The network path between the devices is confirmed to be up. What is the most likely cause of this issue?

   • AThe virtual server is not assigned to a sync group.
   • BThe standby device has a different software version than the active device.
   • CThe iQuery service is not enabled or is blocked between the two devices.
   • DThe pool members are not configured with a health monitor.
