- It could be any of the addresses of the members of the load balancing pool.
-
What does the insert X-Forwarded option in an HTTP profile do?
- A BIG-IP self-IP is inserted in the source address field on the server-side connection.
- A BIG-IP self-IP is inserted in the source address field on the client-side connection.
- The client IP addresses are inserted into messages sent to remote syslog servers.
- The client IP addresses are inserted into HTTP header.
-
When defining a load balancing pool using the command line, if the load balancing method is not specified, what is the result?
- The default load balancing method would be used.
- The load balancing method of the previous pool would be used.
- The system would prompt the user for a load balancing method.
- An error would be displayed since no load balancing method was specified.
-
What occurs when a save-config command is issued?
- The current configuration files are backed up.

Which is a potential result when a trunk is configured on a BIG-IP?
- No additional trunks can be configuration since each BIG-IP is limited to one trunk
- Packets flowing to the VLAN could arrive on any of the interfaces in the trunk
- Since any VLANs associated with the trunk are necessarily associated with multiple interfaces, the VLAN using the must use tagged packets.
- VLAN failsafe is not available for any VLAN associated with any trunks.
-

- All current BIG-IP platform can perform hardware compression.
- Only 2U BIG-IP Platform have an option of a second power supply.
- All BIG-IP have capacity to perform bulk encryption I decryption of SSL traffic independent of the CPU.
-
Which is the result when multiple monitors are assigned to a pool member?
- The member is marked available if sufficient monitors succeed, and as unavailable if insufficient monitors succeed.
- The member is marked as available if any of the monitors succeed.
- The member is marked as unavailable if any of the monitors fails.
- The member is marked available if all monitors succeed, and as marginal if one or more monitors fail(s).
