Refer to the exhibit. You are designing a data center migration from one location to another, which requires all existing VLANs spanned to the new data center to maintain host IP addressing. Two temporary Gigabit Ethernet circuits are available to extend the VLANs at Layer 2 to the new location as trunk links between core switches in each location. Which solution provides maximum fault isolation between the two data centers to ensure that a Layer 2 issue in one data center does not affect the other during the migration?
A) Perform BPDU filtering over the trunk links
B) Run the dual links as multichassis EtherChannel trunk between core switches within each location
C) Enable root guard on the trunk ports at the legacy DC site
D) Perform HSRP filtering over the trunk links to maintain active HSRP gateways within each data center for each VLAN
