An LTM Specialist needs to loadbalance an application using an LTM device to meet the requirements:
The application servers do NOT Support SSL, but client access to the application should be secured.
Multiple requests from the same client should be sent to the same pool member.
All pool members will have roughly the same processing power, and traffic should be distributed evenly.
The LTM device is NOT the pool members' default gateway.

Why was the second client flow permitted by the web server?
An LTM Specialist has a OneConnect profile and HTTP profile configured on a virtual server to load balance an HTTP application.
The following HTTP headers are seen in a network trace when a client connects to the virtual server:

An LTM device has been configured for load balancing a number of different application servers. Configuration changes need to be made to the LTM device to allow administrative management of the servers in 172.16.10/24, 172.16.20/24, and 172.16.30/24 networks. The servers require outbound access to numerous destinations for operations.
Which solution has the simplest configuration changes while maintaining functionality and basic security?
An LTM is configure an application that isseparated into several subdomains across multiple virtual servers. Many of these subdomains require encryption and could be accessed by anyone on the internet. The configuration must NOT result in SSL warnings to end users.
How should the LTM Specialist configure the SSL profiles for these virtual servers?
An TLM Specialist needs to configure a virtual server to terminate SSL connection on the LTM device.
Cryptographic information must be re-authorized for SSL sessions that remain open for longer than 30 seconds.
Which settings should the LTM Specialist configure in the client SSL profile?
When re-licensing an LTM device from the command line interface, which tmsh command should the LTM Specialist use to generate the required information to provide on the F5 licensing portal?
Refer to the exhibit.
A BIG-IP Administrator needs to fall over the active device. The administrator logs into the Configuration
Unity and navigates to Device Management > Traffic Group. However, Force to Standby is greyed out
What is causing this issue?
The BIG-IP Administrator creates a custom iRule that fails to work as expected. Which F5 online resource should the administrator use to help resolve this issue?

An LTM Specialist is reconfiguring a virtual server to redirect all clients to HTTPS. Testing reveals that the redirect is functioning incorrectly. As part of the troubleshooting process, the LTM Specialist performs a packet capture.
What is the issue?
An LTM Specialist needs to create a virtual server to pass TCP traffic to three pool members.
Which two virtual server types should be used to meet the requirements? (Choose two)
A BIG-IP Administrator suspects that one of the BIG-IP device power supplies is experiencing power
outages.
Which log file should the BIG-IP Administrator check to verify the suspicion?
Some users who connect to a busy Virtual Server have connections reset by the BIG-IP system. Pool member resources are NOT a factor in this behavior. What is a possible cause for this behavior?
While investigating the cause of a device failover, an LTM Specialist discovers the following events in /var/log/ltm:
01010029:5: Clock advanced by 518 ticks
01010029:5: Clock advanced by 505 ticks
01010029:5: Clock advanced by 590 ticks

Which issue caused the failover?
Refer to the exhibit.
The BIG-IP Administrator has modified an iRule on one device of an HA pair. The BIG-IP Administrator
notices there is NO traffic on the BIG-IP device in which they are logged into.
What should the BIG-IP Administrator do to verify if the iRule works correctly?
An LTM Specialist has noticed in the audit log that there are numerous attempts to loginto the Admin account. Theses attempts are sourced from a suspicious IP address range to the Configuration Utility of the LTM device.
How should the LTM Specialist block these attempts?
An application is configured on an LTM device:
Virtual server: 10.0.0.1:80 (VLAN vlan301)
SNAT IP: 10.0.0.1
Pool members: 10.0.1.1:8080, 10.0.1.2:8080, 10.0.1.3:8080 (VLAN vlan302)
Which packet capture should the LTM Specialist perform on the LTM device command line interface to capture only client traffic specifically for this virtual server?
