                  HPE Network Data Center Professional Architect Sample Questions:

                  1. 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) An ingress policy not egress policy, is the correct direction for controlling traffic from endpoints.
                  B) When you apply a policy to one network, it is recommended to add all the networks in its VRF to PSM.
                  C) The customer must enable strict firewall mode before applying policies to ensure they take effect.
                  D) The customer should apply the egress policy at both the VRF and network level to ensure that it works properly.


                  2. Which of the following best describes the purpose of a "risk register" in a data center network design project?

                  A) A tracked list of identified risks, their likelihood/impact, and mitigation or contingency plans
                  B) A record of every email exchanged with the customer
                  C) A list of the switches to be purchased
                  D) A financial ledger of the project's profit margin


                  3. 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 Isolated VLAN in a PVLAN configuration is generally not recommended for endpoints because they can communicate freely with all endpoints on the secondary VLANs.
                  B) 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.
                  C) 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.
                  D) 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/


                  4. 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) Link 1 and Link 3 should be one VSX LAG. Link 2 and Link 4 should be another VSX LAG.
                  B) Each link should be a routed-only port (ROP) in a /31 subnet.
                  C) Link 1 and Link 2 should be one VSX LAG. Link 3 and Link 4 should be another VSX LAG.
                  D) All links should be in the same VSX LAG.


                  5. A customer currently has a data center network that uses CX switches and Pensando to implement east-west firewalling. The data center is currently highly virtualized with VMware.
                  However, the customer is considering migrating some workloads to HPE VMs running on HPE Morpheus VM Essentials (VME). What should you explain?

                  A) The customer will not be able to implement microsegmentation between the HPE VMs on the same subnet, but can implement segmentation between VMs on different subnets.
                  B) The customer will not be able to implement the east-west firewall policies for traffic originating from the HPE VMs, but can continue to use the1nnatingcies to secure other data center traffic.
                  C) The customer should use the VME DSS plug-in to utilize the full firewall features, including microsegmentation.
                  D) The customer should purchase the HPE Morpheus Enterprise license to enable support for PVLAN and the full firewall features, including microsegmentation.
