HPE Network Data Center Professional Architect v1.0
Question 1
Refer to the exhibit.
You are designing a data center network. This customer requests that you connect the data center to campus core switches. The customer uses VLANs for segmentation, but not VRFs.
What is the recommended design for the links between the data center core switches and the campus core switches?
- A. Each link should be a routed-only port (ROP) in a /31 subnet.
- B. Link 1 and Link 3 should be one VSX LAG. Link 2 and Link 4 should be another VSX LAG.
- C. All links should be in the same VSX LAG.
- D. Link 1 and Link 2 should be one VSX LAG. Link 3 and Link 4 should be another VSX LAG.
Answer : A
Question 2
A customer has deployed CX 10000 switches. Fabric Composer, and Pensando Policy and Services Manager (PSM). The switches are discovered in PSM but no VRFs or networks are added. Now the customer wants to get started by applying micro-segmentation to one network. The customer tells you that they plan to add a policy with rules for permitting desired traffic from endpoints in this network. They will apply it as an egress policy to the network. At this point they will not add any other networks to PSM or apply policies to them.
What warning should you give the customer about this plan?
- A. The customer should apply the egress policy at both the VRF and network level to ensure that it works properly.
- B. The customer must enable strict firewall mode before applying policies to ensure they take effect.
- C. An ingress policy not egress policy, is the correct direction for controlling traffic from endpoints.
- D. When you apply a policy to one network, it is recommended to add all the networks in its VRF to PSM.
Answer : D
Question 3
You are planning a pair of CX switches to act as ToR switches. The switches implement VSX as part of a data center L2 topology and connect to the core on VSX LAGs. To meet expansion requirements, you need to keep as many ports open as possible.
What option should you recommend for VSX LAGs?
- A. Sending the keepalives to and from loopback interfaces overs the uplinks to the core.
- B. Adding a link between the switches dedicated to the keepalives.
- C. Sending the keepalives to and from loopback interfaces overs the VSX ISL.
- D. Using the OOBM interface to transmit keepalives.
Answer : D
Question 4
What is an advantage of using a VSX-pair instead of two discrete switches to connect servers, storage, firewalls, and other workloads?
- A. You only need to configure a single routing control-plane.
- B. The setup is much easier since both switches are sharing the same configuration.
- C. Bare metal servers can be connected via MLAGs using LACP.
- D. You can save half the number of licenses needed for AFC.
Answer : C
Question 5
Can EVPN/VXLAN Fabrics be configured to protect against Layer 2 loops?
- A. No, a Layer 2 loop on VXLAN Infrastructure is not possible.
- B. Yes, using Spanning-Tree over VXLAN
- C. No, AOS-CX does not support such capability.
- D. Yes, using Loop Protection over VXLAN.
Answer : D
Question 6
What are important characteristics to mention while discussing possible connections for VMware hosts to server-access-switches?
- A. LACP is an old protocol and should no longer be used.
- B. Source MAC Load balancing is always the best option.
- C. VMware ESXi requires the appropriate license to support LACP.
- D. Only bare metal servers running WindowsServer or Oracle Solaris can use LACP.
Answer : C
Question 7
You are proposing an L3 spine and leaf topology to a customer. The solution consists of four CX 8325-32C switches at the spine and two CX 8325-48Y8C switches in each server rack. For this customer, you are using the leaf switches in a rack to provide the border leaf functionality. The customer’s data center is growing and the customer asks you how many total server racks this solution can scale to support.
What should you say?
- A. 15
- B. 16
- C. 30
- D. 32
Answer : B
Question 8
Which statement is true about VSX design?
- A. VSX Inter-Switch Link can implemented over indirect links.
- B. VSX peer keepalive links only supports 40G and 100G ports.
- C. VSX peer keepalive can be implemented over a VSX LAG.
- D. VSX Inter-Switch Link must be implemented using direct links between peers.
Answer : D
Question 9
You are choosing switches for a new rack, which needs to support several types of traffic including HTTPS multicast streaming, and iSCSI traffic You are attempting to choose between CX 8360v2-32Y6C and CX 8325-48Y8C models both of which can meet the racks’ port requirements.
Which technical requirement should point you toward the 8325 model?
- A. A requirement to route the multicast traffic across multiple subnets
- B. A requirement to support a mix of 10GbE and 25GbE server connections
- C. A requirement to allocate two different specific amounts of buffer space to platinum-tier and to gold-tier iSCSI storage
- D. A requirement to support both IP ECN AND PFC
Answer : C
Question 10
Refer to the exhibit.
You could make a change to the services that will save the customer money without affecting the level of support provided. What is that change?
- A. Selecting hardware support only FC 4h OS HW
- B. Selecting SW + TechSupp
- C. Selecting HW Onsite + SW + TechSupp FC 4h OS CDMR
Answer : C
Question 11
What is the best practice for using VSX at the Core of a two-tier design?
- A. You should implement VSX at the core when the access layer operates at layer 2 only.
- B. You should never implement VSX at the core of a two-tier design.
- C. You should implement VSX at the core when the access switches implement EVPN VXLAN.
- D. You should implement VSX at the core when the access is layer 3 only with OSPF routed traffic forwarding between core and access.
Answer : A
Question 12
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 one VRF in which all managed switches have an interface
- B. In the network underlay

- D. In the OOBM network
Answer : D
Question 13
You have designed an L3 spine and leaf topology for a customer’s data center which is highly virtualized with VMware vSphere. This customer already uses HPE Aruba Networking mobility and switching solutions in the campus. You are recommending CX 8325 and CX 9300 switches and Fabric Composer The customer asks you to justify the cost of the Fabric Composer licenses.
What should you explain?
- A. This solution enables the customer to monitor the data center and campus solutions from the same cloud console, eliminating travel costs.
- B. This solution's deep integration with vSphere saves IT time and el’minates costly errors with features like automatic VLAN provisioning.
- C. This solution's integration with ITSMs such as ServiceNow helps cu’tomers troubleshoot more quickly.
- D. This solution uses agentic AI to run the network automatically, reducing IT operational costs.
Answer : B
Question 14
You are presenting the proposed solution to the customer. The customer required micro-segmentation to be implemented so you designed the network to use the Aruba CX 10000 DSS. The customer has questions about the implementation of PVLAN.
What is a true statement about PVLAN that will help the customer understand the fundamentals of micro-segmentation?
- A. The Primary VLAN in a PVLAN configuration does not support having endpoints connected because the local proxy ARP configuration on the SVI excludes the Primary VLAN and only functions for the secondary VLANs/
- B. The Community VLAN in a PVLAN configuration is generally not recommended for endpoints because they can communicate freely with all endpoints on the secondary VLANs.
- C. The Isolated VLAN in a PVLAN configuration is generally not recommended for endpoints because they can communicate freely with all endpoints on the secondary VLANs.
- D. The Primary VLAN in a PVLAN configuration is generally not recommended for endpoints because they can communicate freely with all endpoints on the secondary VLANs.
Answer : D
Question 15
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. For each overlay VRF whether the customer requires L2 multicast forwarding
- B. Whether the customer prefers a single-AS or dual-AS design for the VXLAN control plane
- C. For each overlay VRF, whether it will have DHCP servers to which relay is required
- D. Whether the customer prefers OSPF or BGP as a routing protocol
Answer : C
