   An administrator is configuring a prober pool to monitor a virtual server. They have created the prober pool and need to add the prober virtual servers. Each prober virtual server must be configured with a unique destination IP and port. What is the purpose of assigning a unique destination IP and port to each prober virtual server?

   • ATo ensure that the prober virtual server can be reached by the BIG-IP DNS management interface.
   • BTo define the IP address and port of the monitored virtual server that the prober will check.
   • CTo allow the prober virtual server to listen for incoming health check requests from other BIG-IP systems.
   • DTo ensure that each prober sends probes from a distinct network address, allowing the BIG-IP DNS to identify which prober is reporting.

   A BIG-IP DNS administrator is troubleshooting a virtual server that is not receiving traffic. The virtual server has a TCP monitor attached. The monitor is configured with a timeout of 5 seconds and an interval of 10 seconds. The administrator checks the monitor status and sees that the virtual server is marked 'down'. What does this status indicate about the monitor's findings?

   • AThe TCP monitor is misconfigured because it should be an HTTP monitor for a virtual server.
   • BThe virtual server's pool members are all down, causing the virtual server to be marked down.
   • CThe TCP connection to the virtual server's IP and port failed within the 5-second timeout on the most recent probe.
   • DThe monitor has not yet run its first probe, so the status is temporarily 'down' until the first interval elapses.

   An administrator is setting up a prober pool to monitor a set of virtual servers. They have created the prober pool and need to add the individual probe generators. Each generator must be a BIG-IP virtual server that listens on a specific IP and port, and is associated with the monitor that will be used for the health checks. Which BIG-IP object must the administrator create and add to the prober pool to serve as the probe generator?

   • AA prober virtual server with a defined destination IP and port, and the monitor assigned to it.
   • BA self-IP address on the BIG-IP system's external VLAN.
   • CA SNAT pool with translation addresses on the internal network.
   • DA standard virtual server with a pool of backend web servers attached.

   A company is deploying BIG-IP DNS to manage traffic across two data centers. They have created a data center object for each physical location. Inside each data center, they have defined server objects that represent the BIG-IP systems, and virtual server objects that represent the specific application endpoints. The administrator notices that the data center object shows a status of 'down' even though the BIG-IP server objects inside it are showing 'up'. What is the most likely reason for this discrepancy?

   • AThe BIG-IP server objects are reporting 'up' but the data center is down because the network link between the data centers is down.
   • BThe data center status is derived from the status of the virtual server objects, not the server objects.
   • CThe server objects must be manually marked as 'up' before the data center can be considered up.
   • DThe data center object is always 'down' until a monitor is explicitly assigned to it.
