HPE Network Data Center Professional Architect Exam Sample Questions (Q91-Q96):

NEW QUESTION # 91
What are important characteristics to mention while discussing possible connections for VMware hosts to server-access-switches?

A. Source MAC Load balancing is always the best option.
B. VMware ESXi requires the appropriate license to support LACP.
C. Only bare metal servers running WindowsServer or Oracle Solaris can use LACP.
D. LACP is an old protocol and should no longer be used.

Answer: B

Explanation:
VMware hosts can use LACP only when the required vSphere features/licensing are available, typically with a vSphere Distributed Switch. This is important when designing host-to-access- switch connectivity.

NEW QUESTION # 92
You are designing an L3 spine and leaf topology that uses CX switches. Those switches implement EVPN VXLAN with a distributed gateway model. You are helping implementers to assemble a list of required loopback interface IDs and IP blocks. What information do you need from the customer to complete this list?

A. Whether the customer prefers OSPF or BGP as a routing protocol
B. For each overlay VRF whether the customer requires L2 multicast forwarding
C. Whether the customer prefers a single-AS or dual-AS design for the VXLAN control plane
D. For each overlay VRF, whether it will have DHCP servers to which relay is required

Answer: D

Explanation:
The choice of single-AS versus dual-AS affects the BGP control-plane configuration and AS numbering, not principally the required loopback inventory. Distributed-gateway designs can require dedicated per-VRF loopback addressing for services such as DHCP relay and unique source addressing. HPE also recommends planning an IP block for the loopbacks assigned to each overlay VRF.

NEW QUESTION # 93
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. VSX active forwarding, which enables multiple switches to act as PIM-SM active designated routers at the same time
B. PIM-SM active-active with VSX which enables near instant failover for multicast streams if one core switch fails
C. Fast switchover from the RP tree to the shortest path tree
D. Bootstrap router (BSR) support, which makes the solution more automated and resistant to link failures

Answer: B

Explanation:
Aruba CX with VSX supports enhanced multicast resiliency beyond standard PIM-SM by allowing active-active multicast forwarding and fast recovery if a VSX/core switch fails.

NEW QUESTION # 94
Which information should you attempt to discover during your first data center network design meetings with the customer? (Choose two.)

A. What's the budget allocated to this project?
B. What are the bandwidth requirements for the spine switches?
C. Is it a greenfield or brownfield deployment?
D. What are the data center's addresses?
E. What are the team's training needs for the project?

Answer: A,C

Explanation:
Early design meetings should establish key project context and constraints, such as whether the deployment is greenfield or brownfield and the available project budget. Detailed switch sizing and training planning come later.

NEW QUESTION # 95
You are planning a CX-based data center network that applies east-west firewall policies, managed by AMD Pensando Policy and Services Manager (PSM). Which network should be used to communicate with PSM?

A. In the cloud with access to any overlay VRF to which policies will be applied
B. In the cloud with access to one VRF in which all managed switches have an interface
C. In the network underlay
D. In the OOBM network

Answer: D

Explanation:
PSM is a management/control system for CX 10000 distributed services, so switch-to-PSM communication should use the out-of-band management network, separate from the data underlay and overlay traffic.
