You are designing a Data Center with Spine Leaf architecture. Spine Switches are 8400 with 12 QSFP28 ports (F-B airflow) and leaf switches are 8360 switches stacked with VSX in each rack. The Customer sent you the following Specifications Each Spine Switch uses:

* 1 x 100G QSFP28 5M DACs to each Leaf switch Each Leaf Switch uses:

* 1 x 100G QSFP28 5M DACs to each Spine switch

* 2 x 100G 1M DAC for ISL

* 1 x 25G SFP28 DAC for Keep alive

What is the scalability in this design?

Solution can scale to 12 total racks using the same subscription rates.

Solution can scale to 24 total racks using the same subscription rates.

Solution can scale to 36 total racks using the same subscription rates.

Solution can scale to 48 total racks using the same subscription rates.

Question 55

In one of the spine and leaf designs, VMware vSphere is used including VMware NSX. OSPF is used for routing protocol across the spine and leaf topology. What do you need to consider in this design? (Select three)

Adding an anycast loopback interface on each VSX pair

Using a L2 MTU of 9198 on leaf-to-spine links

Using an IP MTU of 9198 on leaf-to-spine links

Question 56

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 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

Question 58

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?

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
