Question 11

Company XYZ, a global content provider, owns data centers on different continents. Their data center design involves a standard three-layer design with a Layer 3-only core. HSRP is used as the FHRP. They require VLAN extension across access switches in all data centers, and they plan to purchase a Layer 2 interconnection between two of their data centers in Europe. In the absence of other business or technical constraints, which termination point is optimal for the Layer 2 interconnection?

Options:

at the core layer, to offer the possibility to isolate STP domains

at the aggregation layer because it is the Layer 2 to Layer 3 demarcation point

at the access layer because the STP root bridge does not need to align with the HSRP active node

at the core layer because all external connections must terminate there for security reasons
