F5 Networks 301b BIG IP Local Traffic Manager LTM Specialist Maintain & Troubleshoot LTM Exam Practice Test

In preparation for a maintenance task, an LTM Specialist performs a "Force to Standby" on LTM device Unit 1. LTM device Unit 2 becomes active as expected. The maintenance task requires the reboot of Unit 1. Shortly after the reboot is complete, the LTM Specialist discovers that Unit 1 has become active and Unit 2 has returned to standby.

What would cause this behavior?

The pool members are serving up simple static web content.

The current virtual server configuration is given as follows:

tmsh list ltm virtual simple

ltm virtual simple {

destination 10.10.10.10:80

ip-protocol tcp

mask 255.255.255.255

profiles {

http { }

httpcompression { }

oneconnect { }

tcp { }

}

snat automap

vlans-disabled

}

tmsh list ltm pool simple_pool

ltm pool simple_pool {

members {

10.10.10.11:80 {

address 10.10.10.11 }

10.10.10.12:80 {

address 10.10.10.12 }

10.10.10.12:80 {

address 10.10.10.13 }

}

}

Which three objects in the virtual server configuration can be removed without disrupting functionality of the virtual server? (Choose three.)

The decoded TCPDump capture is a trace of a failing health monitor. The health monitor is sending the string shown in the capture; however, the server response is NOT as expected. The receive string is set to 'SERVER IS UP'.

Refer to the exhibit.

An LTM Specialist is investigating reports that users are unable to perform some commands through an FTP virtual server. The users are receiving the FTP error "500 Illegal PORT command." The virtual server is configured to SNAT using automap. The LTM Specialist performs a capture on the server side of the LTM device.

Why is the server returning this error?

Which file should be modified to create custom SNMP alerts?

Given:

Filesystem Size Used Avail Use% Mounted on

/dev/md11 248M 248M 0 100% /

/dev/md13 3.0G 76M 2.8G 3% /config

/dev/md14 3.0G 214M 2.6G 8% /var

prompt 4.0M 12K 4.0M 1% /var/prompt

/dev/md15 12G 8.3G 3.1G 74% /var/lib/mysql

Which command is used to produce this output?

An LTM Specialist has just manually failed the active LTM device over to the standby LTM device. The LTM Specialist notices the newly active LTM device is NOT currently receiving traffic. The LTM Specialist verifies the newly active device is responding to ARP but still no traffic is hitting the virtual servers. The LTM Specialist also notices that the virtual servers eventually start responding.

What should be added to the configuration to resolve the problem?
