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

An LTM Specialist has a single HTTPS virtual server doing SSL termination. No server SSL profile is defined. The pool members are on the internal VLAN answering on HTTP port 80. Users with certain browsers are experiencing issues.Which two locations are most appropriate to gather packets needed to determine the SSL issue? (Choose two.)

• server interface
• user's computer
• LTM device's external VLAN
• LTM device's internal VLAN
• LTM device's management interface

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?

• Unit 1 is set with the redundancy state preference of active in devices groups.
• Unit 1 is set with the redundancy state preference of active in high availability.
• A traffic group is configured with Auto Failback, and Unit 1 is the default device.
• A device group is configured with Auto Failback, and Unit 1 is the default device.

What is the effect of an iRule error such as referencing an undefined variable?

• The iRule execution will continue with the next statement.
• The execution of the current event within the iRule will be terminated.
• The iRule execution will be terminated, and both the client and server side connections will be reset.
• The connection will continue, but the iRule will NOT be executed again for the lifetime of the connection.

A new web application is hosted at www.example.net, but some clients are still pointing to the legacy web application at www.example.com.Which iRule will allow clients referencing www.example.com to access the new application?

• when HTTP_REQUEST { if {[HTTP::host] equals 'www.example.*' }{ HTTP::redirect 'http://www.example.net' } }
• when HTTP_REQUEST { if {[HTTP::host] equals 'www.example.com' }{ HTTP::redirect 'http://www.example.net' } }
• when HTTP_DATA { if {[HTTP::host] equals 'www.example.*' }{ HTTP::redirect 'http://www.example.net' } }
• when HTTP_RESPONSE { if {[HTTP::host] equals 'www.example.com' }{ HTTP::redirect 'http://www.example.net' } }

An LTM Specialist must perform a hot fix installation from the command line.What is the correct procedure to ensure that the installation is successful?

• import the hot fix to the /var/shared/images directory check the integrity of the file with an md5 checksum tmsh apply sys software hotfix volume .iso
• import the hot fix to the /var/shared/images directory check the integrity of the file with an md5 checksum tmsh install sys software hotfix .iso volume
• import the hot fix to the /shared/images directory check the integrity of the file with an md5 checksum tmsh apply sys software hotfix volume .iso
• import the hot fix to the /shared/images directory check the integrity of the file with an md5 checksum tmsh install sys software hotfix .iso volume

An LTM Specialist sees these entries in /var/log/ltm:Oct 25 03:34:31 tmm warning tmm[7150]: 01260017:4: Connection attempt to insecure SSL server (see RFC5746) aborteD. 172.16.20.1:443Oct 25 03:34:32 tmm warning tmm[7150]: 01260017:4: Connection attempt to insecure SSL server (see RFC5746) aborteD. 172.16.20.1:443Oct 25 03:34:32 tmm warning tmm[7150]: 01260017:4: Connection attempt to insecure SSL server (see RFC5746) aborteD. 172.16.20.1:443Oct 25 03:34:32 tmm warning tmm[7150]: 01260017:4: Connection attempt to insecure SSL server (see RFC5746) aborteD. 172.16.20.1:443Oct 25 03:34:32 tmm warning tmm[7150]: 01260017:4: Connection attempt to insecure SSL server (see RFC5746) aborteD. 172.16.20.1:443Oct 25 03:34:33 tmm warning tmm[7150]: 01260017:4: Connection attempt to insecure SSL server (see RFC5746) aborteD. 172.16.20.1:443Assume 172.16.20.0/24 is attached to the VLAN 'internal.'What should the LTM Specialist use to troubleshoot this issue?

• curl -d - -k https://172.16.20.1
• ssldump -i internal host 172.16.20.1
• tcpdump -i internal host 172.16.20.1 > /shared/ssl.pcap ssldump < /shared/ssl.pcap
• tcpdump -s 64 -i internal -w /shared/ssl.pcap host 172.16.20.1 ssldump -r /shared/ssl.pcap

A device on the network is configured with the same IP address as the management address of the active LTM device, causing the management GUI to be inaccessible.Which two methods should the LTM Specialist use to access the LTM device in order to change the management IP address? (Choose two.)

• Connect via ssh to the AOM IP address.
• Connect via ssh to the management address.
• Connect to the LTM device via serial connection.
• Connect a monitor and keyboard to the LTM device.
• Connect via ssh to the standby unit and connect via ssh across the serial link between the devices.

Which command will identify the active LTM device currently handling client traffic?

• b ha table show
• tmsh list /sys ha-status
• tmsh show /cm traffic-group
• tmsh run /sys failover standby
• tmsh show /sys ha-status all-properties

An LTM Specialist is troubleshooting an issue where one LTM device in a three LTM device group is failing to synchronize after a synchronize to group command is issued. The LTM Specialist verifies there are no packet filters, port lock down, or network issues preventing the connection.What are two reasons the synchronization group is having issues? (Choose two.)

• Certificates expired on all of the peer LTM devices.
• Certificates stored for the device trusts on all of the peer LTM devices are corrupted.
• Admin passwords changed on one of the peer LTM devices that are able to synchronize.
• Admin password changed on the LTM device NOT receiving the synchronized configurations.
• Certificates stored for the device trusts on the LTM device NOT receiving the configuration are corrupted.

An LTM Specialist is troubleshooting an issue with a new virtual server. When connecting through the virtual server, clients receive the message 'The connection was reset' in the browser, although connections directly to the pool member show the application is functioning correctly.ltm pool srv1_https_pool {members {192.168.2.1:https{address 192.168.2.1}}}ltm virtual https_example_vs {destination 192.168.1.155:httpsip-protocol tcpmask 255.255.255.255pool srv1_https_poolprofiles {http { }tcp { }}snat automapvlans-disabled}How should the LTM Specialist resolve this issue?

• Enable HTTP monitoring on the pool.
• Add a ClientSSL profile to the virtual server.
• Disable SNAT Automap on the virtual server.
• Remove the HTTP profile from the virtual server.
