• Resources allocated for CPU memory, network interfaces, and disk space
• Virtual disk created
• The guest is NOT running
The guest is NOT running in which state is the VCMP guest
An TLM Specialist has an Exchange that must use the LTM device to route traffic to the internet.

A new DNS virtual server has been configured. Testing reveals that DNS server has failed to accept DNS over TCP. The configuration of the virtual server is as follows:
Which action should be taken to correct this issue?
Refer to the exhibit
Given the bigip conf extract shown where the servers only talk http on port 80, which node will receive the next user request?
Six servers have a varying number of connections that change based on the user load.
Which load balancing method should an LTM Specialist apply to divided the web application traffic to the servers on the relative performance trend?
An LTM Specialist needs to force only FTP traffic, sourced from subnet 10.10.10.0/24 to virtual server 10.10.20.1 to the new FTP1 server. The following virtual servers are configured on the LTM device:
Traffic sourced from 10.10.10/24 must use the specific pool member for load balancing.
Which configuration change is needed to meet the requirements?
The web application team requests help from the LTM Specialist to Improve the performance of their web sites that are load balanced by the F5 LTM device with a Standard Virtual Server.
Which virtual server type will improve the performance of the web application servers?
An LTM Specialist creates an Analytics wide to show the type of browsers used to access a certain application. However, the generated statistics only sum up all transaction for that application under one item called ‘ Aggregated.’’
What should the LTM Specialist do to resolve this problem?
An application is sensitive to packet loss and unexpected session termination. A pair of LTM devices is configured in an Active/Standby high availability configuration. SNATS are NOT used and the virtual server contains a Universal Persistence profile.
which two actions must an LTM Specialist take to ensure the sessions are maintained between the client and server during an LTM device failover event while maintaining maximum uptime? (Choose two.)
An LTM Specialist needs to create a pool with a set of monitor that checks both the pool members and corresponding application service ports. The pool members have services on port 80. The application service is on port 8009.
