Question 2

A BIG-IP has two load balancing virtual servers at 150.150.10.10:80 and 150.150.10.10:443. The port 80 virtual server has SNAT automap configured. There is also a SNAT configured at 150.150.10.11 set for a source address range of 200.200.1.0 / 255.255.255.0. All other settings are at their default states. If a client with the IP address 200.200.1.1 sends a request to https://150.150.10.10,

What is the source IP address when the associated packet is sent to the pool member?

A200.200.1.1

B150.150.10.11

CFloating self IP address on VLAN where the packet leaves the system

DFloating self IP address on VLAN where the packet arrives on the system

Answer : B

Question 3

Which statement describes a typical purpose of iRules?

AiRules can be used to add individual control characters to an HTTP data stream.

BiRules can be used to update the timers on monitors as a server load changes.

CiRules can examine a server response and remove it from a pool if the response is unexpected.

DiRules can be used to look at client requests and server responses to choose a pool member to select for load balancing

Answer : A

Question 4

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 UserAgent] contains "MSIE" }

{ pool MSIE_pool }

else { pool Mozilla_pool }

If a user connects to http://10.10.1.100/foo.html and their browser does not specify a UserAgent, which pool will receive the request?

AMSIE_pool

BMozilla_pool

CNone. The request will be dropped.

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

Answer : B

Question 5

A virtual server is listening at 10.10.1.100:any and has the following iRule associated with it:

when CLIENT_ACCEPTED { if {[TCP::local_port] equals 21 } { pool

ftppool } elseif {[TCP::local_port] equals 23 } { pool telnetpool }

If a user connects to 10.10.1.100 and port 22, which pool will receive the request?

Aftppool

Btelnetpool
