When securing an ESX 4.x host using the built-in firewall,the Startup Policy conterols how services start based on the state of the ports they usE. Which of the following are valid startuo policies?

A.
Start and stop with host

B.
Start and stop automatically

C.
Start automatically if any ports are open, and stop when all ports are closed

D.
Start automatically, opening any closed ports used by this service

Explanation:
Automating Service Behavior Based on Firewall Settings
* Start automatically if any ports are open, and stop when all ports are closed � The default setting for
these services that VMware recommends. If any port is open, the client attempts to contact the network
resources pertinent to the service in question. If some ports are open, but the port for a particular service
is closed, the attempt fails, but there is little drawback to such a case. If and when the applicable outgoing
port is opened, the service begins completing its tasks.
* Start and stop with host� The service starts shortly after the host starts and closes shortly before the host
shuts down. Much like Start automatically if any ports are open, and stop when all ports are closed, this
option means that the service regularly attempts to complete its tasks, such as contacting the specified
NTP server. If the port was closed but is subsequently opened, the client begins completing its tasks shortly
thereafter.
* Start and stop manually � The host preserves the user-determined service settings, regardless of whether
ports are open or not. When a user starts the NTP service, that service is kept running as long as the host
is powered on. If the service is started and the host is powered off, the service is stopped as part of the
shutdown process, but as soon as the host is powered on, the service is started again, preserving the userdetermined state.
