A reboot and restart of the services brings the LTM device to Active mode for a short time, but then it goes into Standby mode again.

Which two configuration components caused this condition? (Choose two.)

A.

VLAN Fail-safe

B.

System Fail-safe

C.

Gateway Fail-safe

D.

Switch Board Failure

E.

Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8

Accept-LanguagE. en-US,en;q=0.5

Accept-EncodinG. gzip, deflate

Cache-Control: no-cache

Connection: keep-alive

CookiE. somecookie=1

Although a stream profile has been added to the virtual server, the content within the HTTP response is NOT being matched, and therefore NOT modified.
