Refer to the exhibit.

Which two sets of procedures are best practices for Layer 2 and 3 failover
alignment? (Choose two.)

A.
Configure the D-SW1 switch as the active HSRP router and the STP root for all VLANs.
Configure the D-SW2 switch as the standby HSRP router and backup STP root for all VLANs.

B.
Configure the D-SW2 switch as the active HSRP router and the STP root for all VLANs.
Configure the D-SW1 switch as the standby HSRP router and backup STP root for all VLANs.

C.
Configure the D-SW1 switch as the active HSRP router and the STP root for VLANs 11 and
110. Configure the D-SW2 switch as the active HSRP router and the STP root for VLANs 12 and
120.

D.
Configure the D-SW1 switch as the standby HSRP router and the backup STP root for VLANs
12 and 120. Configure the D-SW2 switch as the standby HSRP router and the backup STP root
for VLANs 11 and 110.

E.
Configure the D-SW1 switch as the standby HSRP router and the STP root for VLANs 11 and
110. Configure the D-SW2 switch as the standby HSRP router and the STP root for VLANs 12 and
120.

F.
Configure the D-SW1 switch as the active HSRP router and the backup STP root for VLANs 11
and 110. Configure the D-SW2 switch as the active HSRP router and the backup STP root for
VLANs 12 and 120.

Explanation:
The “best practices for Layer 2 and 3 failover alignment” here means using load sharing of HSRP
where different VLANs use different active routers to load balance the traffic.
To load sharing with HSRP, we can divide traffic into two HSRP groups, where one group assigns
the active state for one switch and the other group assigns the active state for the other switch
