HP HPE7-A04 Aruba Certified Data Center Architect Exam Exam Practice Test Questions

• Question 1

  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 4

  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
