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) When you apply a policy to one network, it is recommended to add all the networks in its VRF to PSM.
B) An ingress policy not egress policy, is the correct direction for controlling traffic from endpoints.
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. You are designing a CX data center network for a customer who has indicated that they must integrate the switches in their automation workflows. Which capability enables your customer to fulfill their objectives?

A) REST API with JSON
B) gRPC
C) NETCONF
D) XML API

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 Primary 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 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/
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 Community VLAN in a PVLAN configuration is generally not recommended for endpoints because they can communicate freely with all endpoints on the secondary VLANs.

4. You are designing an L3 spine and leaf architecture for a customer based on CX 10000 Series switches as leaf switches. The customer has added a requirEMENT that the leaf switches also support servers' iSCSI adapters. You have verified your design also meETS The customer's needs for lossless iSCSI. The customer asks for advice on ensuring that THE East-west firewall permits the iSCSI traffic. What should you explain?

A) CX 10000 switches do not implement east-west firewall policies on traffic in a no-drop PFC queue.
B) Fabric Composer supports VM tag-based Endpoint Groups (EPGs) which will make it easy for the customer to select the iSCSI traffic and permit it.
C) The customer should place the iSCSI adapters in a PVLAN primary VLAN to ensure trafFIC Is permitted.
D) The custOMER should place the iSCSI adapters in a PVLAN isolated VLAN to ensure traFFIC is forwarded without disruption from VM traffic.

5. The customer operates a 24/7 production facility and is concerned that the migration will disrupt the production line. What are two ways to minimize or eliminate this disruption? (Choose two.)

A) Close the production site for at least 1 day to do a bing-bang approach
B) Whenever possible, ramp up the new infrastructure in parallel and do transparent switching from old to new core switch.
C) Create a Migration Plan which describes a phased approach, i.e. access layer first, distribution layer second, etc.
D) Replace one access switch at a time and patch the ports by using a patch plan.
