   An administrator needs to decommission one of three BIG-IP DNS devices in an iQuery mesh. The device to be removed is currently the sync master. The administrator wants to minimize disruption to DNS resolution services. What should the administrator do first?

   • AChange the sync master role to one of the remaining devices, verify sync, then remove the device from the mesh.
   • BPower down the device, then remove it from the mesh using the CLI.
   • CForce a manual sync from the device to be removed to the remaining devices, then remove it from the mesh.
   • DRemove the device from the mesh using the Configuration utility, then power it down.

   An engineer is adding a new BIG-IP DNS device to an existing iQuery mesh. The engineer has verified TCP 4353 connectivity from the new device to all existing mesh members. The new device's NTP is synchronized. However, the add operation fails with a certificate validation error. The existing mesh members use self-signed certificates. What is the most likely cause and solution?

   • AThe new device's management IP is not reachable from the existing members; verify reverse connectivity.
   • BThe existing mesh members' certificates have expired; renew them on all devices and retry.
   • CThe new device does not trust the existing members' certificates; import the existing members' certificates into the new device's trust store.
   • DThe new device's clock is skewed by more than the allowed tolerance; resynchronize NTP and retry.

   An administrator is removing a BIG-IP DNS device from an iQuery mesh. The device is currently the sync master. The administrator has already transferred the sync master role to another device and verified that synchronization is healthy. What is the next step?

   • APower down the device before removing it from the mesh.
   • BBack up the device's configuration before removal.
   • CRemove the device from the mesh using the Configuration utility.
   • DReboot the device to ensure it releases the sync master role.
