You are employed as a network administrator at ABC.com. ABC.com has an Active Directory
domain named ABC.com. All servers on the ABC.com network have Windows Server 2012
installed.
You are running a training exercise for junior network administrators. You are currently discussing
DHCP failover architecture. You have informed the trainees that DHCP servers can be deployed
as failover partners in either hot standby mode or load sharing mode.
Which of the following is TRUE with regards to hot standby mode? (Choose all that apply.)
A.
It is when two servers function in a failover relationship where an active server is responsible
for leasing IP addresses and configuration data to all clients in a scope or subnet.
B.
It when two servers in a failover relationship serve IP addresses and options to clients on a
given subnet at the same time.
C.
It is best suited to deployments where a data center server acts as a standby backup server to
a server at a remote site.
D.
It is best suited to deployments where both servers in a failover relationship are located at the
same physical site.

Explanation:
In hot standby mode, two servers operate in a failover relationship where an active server is responsible for leasing IP addresses and configuration information to all clients in a scope or subnet. The partner server assumes a standby role, with responsibility to issue leases to DHCP clients only if the active server becomes unavailable. Hot standby mode is ideal for scenarios where the failover partner is only intended to be used temporarily when the active server is unavailable.
The hot standby mode of operation is best suited to deployments where a central office or data center server acts as a standby backup server to a server at a remote site, which is local to the DHCP clients (ex: hub and spoke deployment). In such deployments, it is undesirable to have a remote standby server service any clients unless the local DHCP server becomes unavailable. The following figure is an example of a hub and spoke deployment.
