HPE Network Data Center Professional Architect Exam

Question 1

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. Ask for another subnet for point-to-point links in the overlay VRF

B. Ask for another subnet for loopback IP addresses shared by the two members of each VSX pair

C. Change the /24 subnet request for the point-to-point links to a /23 subnet

D. Change the /24 subnet request for the individual loopback addresses to a /25 subnet

Question 2

Which two factors should be part of a data center network's high availability (HA) design?
(Choose two.)

A. Disabling LACP to simplify configuration

B. VSX (Virtual Switching Extension) between top-of-rack switch pairs

C. Selecting a single top-of-rack switch per rack with no backup

D. Redundant power and diverse uplinks between tiers

E. Placing all spine switches in a single power zone

Question 3

Which of the following is an appropriate deliverable to include in a High-Level Design (HLD) document, as opposed to a Low-Level Design (LLD)?

A. Exact port-by-port cabling diagram

B. Specific IP addressing for every VLAN

C. Switch configuration CLI commands

D. Conceptual topology diagram and overall architecture rationale

Question 4

You have delivered a CX 10000-based data center network to a customer. The customer wants to ensure a smooth transition to the new network before starting to implement the security capabilities. What should you recommend for the initial deployment?

A. Making sure that all networks have been added to PSM with an egress policy that has no rules

B. Making sure that all VRFs have been added to PSM with an ingress policy that has no rules

C. Making sure that strict firewall bypass is enabled for ARP broadcasts

D. Making sure that strict firewall mode is disabled

Question 5

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?

Question 6

A customer wants to convert as many upfront costs into smaller ongoing bills as possible. For which components can HPE GreenLake for Networking provide recurring billing?

A. Hardware software, and support

B. Hardware and software, but not support

C. Hardware and support, but not software

D. Software and support, but not hardware

Question 7

When creating an endpoint group in Aruba Fabric Composer, which option do you select in the endpoints section if you want to protect the hypervisor?

A. VM Kernel Adapter

B. VM Name

C. VNIC

D. VM Tag

Question 8

Refer to the exhibit.

You are designing a data center network. This customer requests that you connect the data center core their firewalls. The customer uses six VRFs for segmentation, and the firewalls are responsible for handling traffic in all of the VRFs.
What is the recommended design for the links between the data center core switches and the firewalls?

A. Link 1 and Link 3 should be one VSX LAG. Link 2 and Link 4 should be another VSX LAG.

B. Link 1 and Link 2 should be one VSX LAG. Link 3 and Link 4 should be another VSX LAG.

C. All links should be in the same VSX LAG.

D. Each link should be a routed-only port (ROP) in a /31 subnet.

Question 9

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. PIM-SM active-active with VSX which enables near instant failover for multicast streams if one core switch fails

B. Fast switchover from the RP tree to the shortest path tree

C. Bootstrap router (BSR) support, which makes the solution more automated and resistant to link failures

D. VSX active forwarding, which enables multiple switches to act as PIM-SM active designated routers at the same time
