HP HPE7-A12 Exam Syllabus Topics:

HPE Network Data Center Professional Architect Sample Questions:

1. You have designed a two-tier L2 data center network for a customer. When you are presenting the solution, the customer indicates that they have a mission-critical multicast application with sources and receivers in the data center. Which CX feature, beyond features provided by the PIM-SM standard, should you explain to emphasize the value of your solution?

A) Bootstrap router (BSR) support, which makes the solution more automated and resistant to link failures
B) Fast switchover from the RP tree to the shortest path tree
C) VSX active forwarding, which enables multiple switches to act as PIM-SM active designated routers at the same time
D) PIM-SM active-active with VSX which enables near instant failover for multicast streams if one core switch fails

2. You have designed a spine and leaf topology, which includes 16 leaf switches and four spine switches. The customer has no existing overlay solution. You are helping the implementer work with the customer to obtain IP address blocks for the design. You plan to ask for these /24 subnets. One for an individual loopback interface for each switch. One for point-to-point connections between leaf and spine switches. What is one of the corrections you must make?

A) Change the /24 subnet request for the individual loopback addresses to a /25 subnet
B) Ask for another subnet for point-to-point links in the overlay VRF
C) Change the /24 subnet request for the point-to-point links to a /23 subnet
D) Ask for another subnet for loopback IP addresses shared by the two members of each VSX pair

3. To prepare for a data center network implementation, you have asked a customer for a list of VLANs to support. The customers list for several VMware ESXi hosts includes 4095. What follow up question should you ask?

A) Because this VLAN ID is reserved for the system on CX switches, is the customer open to changing that VLAN ID?
B) What VLAN tags do the VMs connected to the 4095 port group use?
C) Is the customer using NSX to support this non-standard VLAN?
D) Is VLAN 4095 associated with the same subnet on all of those hosts?

4. A customer asks whether they should adopt a routed (Layer 3) access design or a bridged (Layer
2) access design for their new data center fabric. Which factor most strongly favors a routed access design?

A) The customer wants to minimize the fault domain size and avoid spanning-tree dependency, and applications don't require L2 adjacency beyond the rack
B) The customer has no requirement for scalability
C) The customer has many legacy applications requiring Layer 2 adjacency across racks
D) The customer wants to run VMware vMotion across the entire data center without any L3 boundary

5. To secure the network, which feature or capability should be implemented?

A) Bluetooth dongle
B) Control-Plane Access Control Lists
C) VSF on spines/cores layer
D) Disable access to RESTAPI
