  A. /war /log/daemon.log

  B. /var/log/kern.log

  Correct Answer: C

• Question 232:

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

  Correct Answer: B

• Question 233:

  A BIG-IP Administrator needs to remove a pool specific health monitor. There is a pool named Best Pool with two members, one named Best pool member and one named Best pool member2. In the Local Traffic section of the administrative GUI, which stops should the BIG-IP Administrator take to remove a pool level monitor?

  A. Pool > Pool List > Best Pool > Members > Health Monitors

  B. Nodes > Node List> Best _pool_memberl > Heath Monitors

  C. Monitors > Monitor Name> Instances

  D. Pool > Pool List> Best Pool > Health Monitors

• Question 234:

  Where should the BIG-IP Administrator apply this monitor?

  A. Local Traffic > Profiles ?Protocol>; TCP

  B. Local Traffic > Nodes > Default Monitor

  C. Local Traffic > Pools > De Pool > Members

  D. Local Traffic > Pools > DB Pool > Properties

  Correct Answer: D

• Question 235:

  Generally speaking, should the monitor templates be used as production monitors or should they be customized prior to use.

  A. Most templates, such as http and tcp, are as effective as customized monitors.

  B. Monitor template customization is only a matter of preference, not an issue of effectiveness or performance.

  C. Most templates, such as https, should have the receive rule customized to make the monitor more robust.

  D. While some templates, such as ftp, must be customized, those that can be used without modification are not improved by specific changes.

  Correct Answer: C

• Question 236:

  A BIG-IP Administrator needs to find which modules have been licensed for use on the BIG-IP system. In which section of the Configuration Utility can the BIG-IP Administrator find this information?

  A. System > Services

  B. System > Resource Provisioning

  C. System > Platform

  D. System > Support

  Correct Answer: B

• Question 237:

  A BIG-IP Administrator uses a device group to share the workload and needs to perform service on a BIG-IP device currently active for a traffic group. The administrator needs to enable the traffic group to run on another BIG-IP device in the device group. What should the administrator do to meet the requirement?

  A. Create a new Traffic Group and then fail to Standby Unit

  B. Select Traffic Group and then select Failover

  C. Select Traffic Group and then select Force to Standby

  D. Select Traffic Group on Primary Unit and then select Demote

  Correct Answer: C

• Question 238:

  Which Virtual Server type should be used to load balance HTTP traffic to a pool of servers?

  A. Standard

  B. Stateless

  C. Forwarding (IP)

  D. Forwarding (Layer 2)

  Correct Answer: A

• Question 239:

  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

  Explanation: 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 240:

  Given that VLAN failsafe is enabled on the external VLAN and the network that the active BIG-IP's external VLAN is connected to has failed, which statement is always true about the results?

  A. The active system will note the failure in the HA table.

  B. The active system will reboot and the standby system will go into active mode.

  C. The active system will failover and the standby system will go into active mode.

  D. The active system will restart the traffic management module to eliminate the possibility that BIG-IP is the cause for the network failure.

  Correct Answer: A
