Free Aruba Certified Data Center Architect Exam HPE7-A04 Exam Practice Test

What is a use case for a two-tier L2 design for a dedicated data center?

• Server room adjacent to campus core
• Customers with medium-to-large data centers with application demanding requirements
• Customers with small-to-medium data centers with less demanding requirements
• Data Center that is located in a separate building to the campus network

What is recommended for the routing protocol setup on leaf VSX pairs?

• Configure the leaf VSX members to establish neighbor relationships with each other over one of the server subnets
• Have the VSX members connect to each spine switch on an L3 VSX LAG and become neighbors with each other and the spine on its subnet
• Add a dedicated VLAN to the VSX ISL, assign it a /31 subnet, and run the routing protocol on it
• Do not configure the routing protocol to run directly between the leaf VSX members

What Fiber Optic standard supports up to 400 Gbps

• No standard supports that bandwidth
• QSFP+
• QSFP28
• QSFP-DD

Which switch model has the following specifications:32 ports of 100GbE, 200GbE, or 400GbE400 Gbps ports can be configured as 4x100GbE, 2x200GbE, or 1x400GbE

• CX 8100 Switch Series
• CX 8360v2 Switch Series
• CX 8325 Switch Series
• CX 9300 Switch Series

What is a rule of thumb for oversubscription ratio on the ToR switches for a two-tier network design?

• 12:1-14:1
• 1:1-2:1
• 6:1-10:1
• 3:1-5:1

HPE Aruba Networking switch selector is accessible from

• Intangi IRIS design tool
• Aruba Support Portal
• HPE PSNow tools
• From NetEdit management tool

You are designing an overlay solution for two Data Centers based on the Aruba CX platform. Each Data Center has two rooms and each room is its own fabric. What is the underlay routing protocol run within each room?

• iBGP
• eBGP
• OSPF
• IS-IS

Which of these protocols carries commands for reading from/writing to storage over a TCP/IP session?

• RDMA
• iSCSI
• NVMeoF-RDMA
• FCoE

What is the transit VLAN that runs between VSX members?

• Must not be assigned IP addresses on any switch.
• It is used as a keepAlive mechanism
• It is a routed VLAN allowed in the ISL to ensure that the two switches within a VSX pair can learn routes from one another, in potential failover situations
• Must be assigned identical IP address on both of the switches

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
