Depending on a switch's role in the topology, the demands on various tables differ. Several HPE Aruba CX switch models support different profiles, each of which optimizes the correct table for a switch with the corresponding role:

L3 Aggregates profile allocates more space to the ARP/ND table compared to L3 core profile

L3 Aggregates profile allocates more space to the support more overlay host entries table compared to leaf switches

L3 Aggregates profile allocates more space to the routing table compared to L3 core profile

L3 Aggregates profile allocates more space to the ARP/ND table compared to L3 core profile

L3 Aggregates profile allocates more space to the routing table compared to Spine switch

A customer currently has a three-tier architecture in which aggregation switches are the default gateways. Pairs of aggregation switches use VRRP. You are migrating to an L2 two-tier architecture in which the core switches are the default gateways. How should you migrate the default gateway functionality?

Add the core switches to the aggregation switches' VRRP groups and use VRRP to fail over to the new switches

Use a DHCP server to assign servers new gateway IP addresses, which are configured on the new core switches

Configure VSX active gateway on the new core switches using the current default gateway IP address as the virtual IP and a new virtual MAC address

Add the core switches to the aggregation switches' VRRP groups and use VRRP to fail over to the new switches

Configure VSX active gateway on the new core switches using a new default gateway IP address as the virtual IP and the existing VRRP MAC for the virtual MAC address

In preparation for the deployment, what statement is correct from the below?

Migrate Layer 2 functionality (e.g., VLAN tagging on uplinks) then cut over to Layer 3 function (e.g., default gateways)

It is best if you migrate Layer 2 functionality (e.g., VLAN tagging on uplinks) and Layer 3 function (e.g., default gateways) simultaneously

If you have spent good time on your design, there is no need to have any rollback plan

It is not best practice to build the new network in parallel to the existing network

Migrate Layer 2 functionality (e.g., VLAN tagging on uplinks) then cut over to Layer 3 function (e.g., default gateways)
