Which statement is true concerning a functional iRule?
A.iRules use a proprietary syntax language.
B.iRules must contain at least one event declaration.
C.iRules must contain at least one conditional statement.
D.iRules must contain at least one pool assignment statement.

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.
D.If an iRule references an event that doesn't occur during the client's communication, the client's connection will be terminated prematurely.

Which statement is true concerning cookie persistence?
A.Cookie persistence allows persistence independent of IP addresses.
B.Cookie persistence allows persistence even if the data are encrypted from client to pool member.
C.Cookie persistence uses a cookie that stores the virtual server, pool name, and member IP address in clear text.
D.If a client's browser accepts cookies, cookie persistence will always cause a cookie to be written to the client's file system.
[单选题]
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.

Which statement is true concerning the default communication between a redundant pair of BIG-IP devices?

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.
D.Connection mirroring data is shared through the serial fail over cable unless network failover is enabled.

Which two statements are true about SNATs? (Choose two.)
A.SNATs are enabled on all VLANs, by default.
B.SNATs can be configured within a Profile definition.
C.SNATs can be configured within a Virtual Server definition.

Which statement is true about the synchronization process, as performed by the Configuration Utility or by typing b config sync all?
A.The process should always be run from the standby system.
B.The process should always be run from the system with the latest configuration.
C.The two /config/bigip.conf configuration files are synchronized (made identical) each time the process is run.
D.Multiple files, including /config/bigip.conf and /config/bigip_base.conf, are synchronized (made identical) each time the process is run.

Which statement is true regarding failover?
A.Hardware failover is disabled by default.
B.Hardware failover can be used in conjunction with network failover.
C.If the hardware failover cable is disconnected, both BIGIP devices will always assume the active role.
D.By default, hardware fail over detects voltage across the failover cable and monitors traffic across the internal VLAN.

Assume a BIG-IP has no NATs or SNATs configured. Which two scenarios are possible when client traffic arrives on a BIG-IP that is NOT destined to a self-IP? (Choose two.)
A.If the destination of the traffic does not match a virtual server, the traffic will be discarded.
B.If the destination of the traffic does not match a virtual server, the traffic will be forwarded based on routing tables.
C.If the destination of the traffic matches a virtual server, the traffic will be processed per the virtual server definition.
D.If the destination of the traffic matches a virtual server, the traffic will be forwarded, but it cannot be loadbalanced since no SNAT has been configured.

Which statement accurately describes the difference between two loadbalancing modes specified as "member" and "node"?
A.There is no difference; the two terms are referenced for backward compatibility purposes.
B.When the loadbalancing choice references "node", priority group activation is unavailable.
C.Loadbalancing options referencing "nodes" are available only when the pool members are defined for the "any" port.
D.When the loadbalancing choice references "node", the addresses' parameters are used to make the loadbalancing choice rather than the member's parameters.
