A virtual server is listening at 10.10.1.100:80 and has the following iRule associated with it: when
HTTP_REQUEST { if { [HTTP::header User-Agent] contains "MSIE" } { pool MSIE_pool } else {

a User-Agent, which pool will receive the request?

A.

MSIE_pool

B.

Mozilla_pool

C.

None. The request will be dropped

D.

Unknown. The pool cannot be determined from the information provided.

equals 23 } { pool telnet pool } If a user connects to 10.10.1.100 and port 22, which pool will
receive the request?

A.

ftp pool

B.

telnet pool

C.

None. The request will be dropped.

D.

Unknown. The pool cannot be determined from the information provided.

When configuring a Virtual Server to use an iRule with an HTTP_REQUEST event, which lists
required steps in a proper order to create all necessary objects?

B.

create the Virtual Server, create required pools, create the iRule, edit the Virtual Server

C.

create a custom HTTP profile, create required pools, create the Virtual Server, create the iRule

D.

create required pools, create a custom HTTP profile, create the iRule, create the Virtual Server

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.

What is the purpose of floating self-IP addresses?

A.

to define an address that grants administrative access to either system at any time

B.

to define an address that allows either system to initiate communication at any time

C.

to define an address that allows network devices to route traffic via a single IP address

D.

to define an address that gives network devices greater flexibility in choosing a path to forward
traffic

C.

Persistence mirroring data is shared via a TCP connection using port 1028
