Question 244

What is the purpose of floating self-IP addresses?

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

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

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

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

Question 246

Which two statements are true concerning the default communication between a redundant pair of BIG-IP systems? (Choose two.)

Synchronization occurs via a TCP connection using ports 683 and 684.

Connection mirroring data is shared via a TCP connection using port 1028.

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

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

Question 247

Which two methods can be used to determine which BIG-IP is currently active? (Choose two.)

The bigtop command displays the status.

Only the active system's configuration screens are active.

The status (Active/Standby) is embedded in the command prompt.

The ifconfig a command displays the floating addresses on the active system.

Question 248

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?

Host names do not matter in redundant pair communication.

In a redundant pair, the two systems will always have the same host name. The parameter is synchronized between the systems.

The first time the systems are synchronized the receiving system will be assigned the same self-IP addresses as the source system.

When the administrator attempts to access the configuration utility using the host name, they will always connect to the active system.
