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?
at the core layer, to otter the possibility to isolate STP domains
at me 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

A customer migrates from a traditional Layer 2 data center network into a new SDN-based spine-and-leaf VXLAN EVPN data center within the same location The networks are joined to enable host migration at Layer 2 What is the final migration step after hosts have physically migrated to have traffic flowing through the new network without changing any host configuration?
Shut down legacy Layer 3 SVIs. clear ARP caches on all hosts being migrated and then configure the legacy VRRP address onto new VXLAN core switches
Increase VRRP priorities on new infrastructure over legacy VRRP values, then shut down legacy SVIs
Shut down legacy infrastructure to allow VXLAN gateways to become active
Shut down legacy Layer 3 SVIs and activate new preconfigured Layer 3 SVIs on VXLAN
