Questions # 36:

A custom TCP application using a single server is being migrated to the LTM device. A server is being added to the pool. The application is known to violate the TCP protocol RFC. Theapplication currently works without error from a user perspective.

Which virtual server type is appropriate in this situation?

Options:

A.

Stateless TCP protocol is not applicable


B.

Questions # 37:

A development team needs to apply a software fix and troubleshoot one of its servers. The BIG-IP Administrator needs to immediately remove all connections from the BIG-IP system to the back end server. The BIG-IP Administrator checks the Virtual Server configuration and finds that a persistence profile is assigned to it. What should the 8IG-IP Administrator do to meet this requirement?

Options:

A.

Set the pool member to a Forced Offline state and manually delete easting connections through the command line.


B.

Set the pool member to a Forced Offline state.


C.

Set the pool member to a Disabled state.


D.

Set the pool member to a Disabled state and manually delete existing connections through the command line.
