Question 2

As a part of the Setup Utility, the administrator sets the host name for the BIG IP. What would be the
result if the two systems in a redundant pair were set to the same host name?

• A. Host names do not matter in redundant pair communication.
• B. In a redundant pair, the two systems will always have the same host name. The parameter is synchronized between the systems.
• C. The first time the systems are synchronized the receiving system will be assigned the same self-IP addresses as the source system.
• D. When the administrator attempts to access the configuration utility using the host name, they will always connect to the active system.

Answer:

C

• B. Only the active system's configuration screens are active.
• C. The status (Active/Standby) is embedded in the command prompt.
• D. The ifconfig a command displays the floating addresses on the active system.

Answer:

A, C

Question 4

Which two statements are true concerning the default communication between a redundant pair of

• A. Synchronization occurs via a TCP connection using ports 683 and 684.
• B. Connection mirroring data is shared via a TCP connection using port 1028.
• C. Persistence mirroring data is shared via a TCP connection using port 1028.
• D. Connection mirroring data is shared through the serial fail over cable unless network failover is enabled. 101/102 Questions & Answers PDF P-

Question 6

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

Answer:

C

Question 7

• 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.

Answer:

B

Question 8

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?
A. ftppool
B. telnetpool

Which statement describes a typical purpose of iRules?

• A. iRules can be used to add individual control characters to an HTTP data stream.
• B. iRules can be used to update the timers on monitors as a server load changes.
• C. iRules can examine a server response and remove it from a pool if the response is unexpected.
