F5 301b - LTM Specialist: Maintain & Troubleshoot

An LTM Specialist is troubleshooting a problem on an eCommerce website. The user browses the online store using port 80, adding items to the shopping cart. The user then clicks the "Checkout" button on the site, which redirects the user to port 443 for the checkout process. Suddenly, the user's shopping cart is shown as empty. The shopping cart data is stored in memory on the server, and the default source address persistence profile is used on both virtual servers.

What is the issue?

A web application requires knowledge of the client's true IP address for logging and analysis purposes. Instances of the application that can decode X-Forwarded-For HTTP headers reside in pool_a, while pool_b instances assume the source IP is the true address of the client.

Which iRule provides the proper functionality?

An LTM Specialist realizes that a datacenter engineer has changed the console baud rate.

Which command determines the current baud rate via the command line interface?

Given this as the first packet displayed of an ssldump:

In reviewing the rest of the ssldump, the application data is NOT being decrypted.

Why is ssldump failing to decrypt the application data?

The active LTM device in a high-availability (HA) pair performs a failover at the same time the network team reports an outage of a switch on the network.

Which two items could have caused the failover event? (Choose two.)

A stand-alone LTM device is to be paired with a second LTM device to create an active/standby pair. The current stand-alone LTM device is in production and has several VLANs with floating IP addresses configured. The appropriate device service clustering (DSC) configurations are in place on both LTM devices.

Which two non-specific DSC settings should the LTM Specialist configure on the second LTM device to ensure no errors are reported when attempting to synchronize for the first time? (Choose two.)

A pair of LTM devices are deployed in a high-availability (HA) pair as the diagram shows. After inserting a new rule on the firewalls, the LTM devices become Standby. The rule drops all outbound sessions to the Internet. Only inbound connections are allowed from the Internet. There are no other changes to the environment.

What triggered the LTM device failover?

A web application requires the client to provide the destination server and service identification.

Which HTTP header will supply this information?

An LTM Specialist configures two LTM devices in a high-availability pair with trusts established and device groups configured properly using network failover. After several months, the LTM Specialist notices that changes made to one LTM device do NOT cause the synchronization status to update to "changes pending," and this device does NOT synchronize with the device group.

Which two steps should the LTM Specialist take to identify the issue? (Choose two.)
