Question 19

A standard virtual server is defined with a pool and a SNAT using automap. All other settings for the virtual server are at defaults. When client traffic is processed by the BIG-IP, what will occur to the IP addresses?

A. Traffic initiated by the pool members will have the source address translated to a self-IP address but the destination address will not be changed.

B. Traffic initiated to the virtual server will have the destination address translated to a pool member address and the source address translated to a self-IP address.

C. Traffic initiated by selected clients, based on their IP address, will have the source address translated to a self-IP address but the destination will only be translated if the traffic is destined to the virtual server.

D. Traffic initiated to the virtual server will have the destination address translated to a pool member address and the source address translated to a self-IP addres

E. Traffic arriving destined to other destinations will havethe source translated to a self-IP address only.

Correct Answer:B

Question 20

How should a BIG-IP Administrator control the amount of traffic that a newly enabled pool member receives.

A. set the Slow Ramp Time

B. set a Connection Limit

C. set the Priority Group Activation

D. set a Health Monitor

Correct Answer:A
Slow Ramp Time
Specifies the duration during which the system sends less traffic to a newly-enabled pool member. The amount of traffic is based on the ratio of how long the pool member has been available compared to the slow ramp time, in seconds. Once the pool member has been online for a time greater than the slow ramp time, the pool member receives a full proportion of the incoming traffic. Slow ramp time is particularly useful for the least connections load balancing mode.
Setting this to a nonzero value can cause unexpected Priority Group behavior, such as load balancing to a low-priority member even with enough high-priority servers.

Question 21

A BIG-IP Administrator makes a configuration change to the BIG-IP device. Which file logs the message regarding the configuration change?

A. /var/log/messages

B. /var/log/audit

C. /var/log/user.log

D. /var/log/secure

Correct Answer:B
About audit logging
Audit logging is an optional feature that togs messages whenever a BIG-IP® system object, such as a virtual server or a load balancing pool, is confined (that is. created, modified, or deleted). The BiGIP system logs the messages for these auditing events in the file /var/log'audit
There are three ways that objects can be configured
• By user action
• By system action
• By loading configuration data
Whenever an object is configured in one of these ways, the BIG-IP system logs a message to the audit log
