Which statement is true concerning SNATs using automap?
A.Only specified self-IP addresses are used as automap addresses.
B.SNATs using automap will translate all client addresses to an automap address.
C.A SNAT using automap will preferentially use a floating self-IP over a nonfloating self-IP.
D.A SNAT using automap can be used to translate the source address of all outgoing traffic to the same address regardless of which VLAN the traffic is sent through.

Which statement is true concerning iRule events?
A.All iRule events relate to HTTP processes.
B.All client traffic has data that could be used to trigger iRule events.
C.All iRule events are appropriate at any point in the clientserver communication.

Which statement is true concerning the default communication between a redundant pair of BIG-IP devices?
A.Communication between the systems cannot be effected by port lockdown settings.
B.Data for both connection and persistence mirroring are shared through the same TCP connection.
C.Regardless of the configuration, some data is communicated between the systems at regular intervals.

Which statement is true concerning SSL termination?
A.A virtual server that has both ClientSSL and ServerSSL profiles can still support cookie persistence.
B.Decrypting traffic at the BIG-IP allows the use of iRules for traffic management, but increases the load on the pool member.
C.When any virtual server uses a ClientSSL profile, all SSL traffic sent to the BIG-IP is decrypted before it is forwarded to servers.
D.If a virtual server has both a ClientSSL and ServerSSL profile, the pool members have less SSL processing than if the virtual server had only a ClientSSL profile.
