What is the difference between the pilot light and warm standby disaster recovery

$($DR$)$ patterns? $($Select TWO.$)$

Pilot light has a scaled$-$down version of all infrastructure that runs until a

disaster occurs.

Warm standby has a scaled$-$down version of all infrastructure that runs until

a disaster occurs.

Warm standby has a second fully functional set of infrastructure that runs

all the time.

Pilot light has minimal infrastructure that always runs. The rest does not run

until a disaster occurs.

With warm standby, all infrastructure runs in sleep mode and is awakened

when a disaster occurs.
