HP Creating HPE Software-defined Networks - HPE2-Z38 Exam Questions [2026]

QUESTION NO: 1
What is a key advantage of software-defined networking (SDN) as compared to traditional networking?

A. SDN allows companies to deploy software-only switches and routers, which can be managed from a centralized console. B. With SDN, a network can be influenced by external applications to enable it to change as the applications require. C. SDN promotes interoperability through open standards such as OpenFlow but supports vendor-specific features as needed. D. With SDN, network management is simplified because all pure OpenFlow switches can be managed through a single pane-of-glass management console

Correct Answer: A

QUESTION NO: 2
A company has an HP VAN SDN Controller solution that runs the HP Network Protector SDN Application.
The application should continue to permit connectivity for legitimate traffic and to protect against new threats if the controller hardware fails.
How can the network administrator meet this requirement?

A. Increase the timeout for the inspection flow entries and the blocking entries to the maximum B. Deploy additional HP VAN SDN Controllers and configure them as a team. C. Configure all switches controlled by the controller to use "secure" for their connection interruption mode. D. Deploy an additional HP VAN SDN Controller in standby or passive mode.

Correct Answer: C

QUESTION NO: 3
A company has HP VAN SDN Controllers which form a team Assume that all switches are configured correctly to use all controllers in the team The team leader fails After the team detects the failure, what happens?

A. The team elects one of the remaining controllers as the new leader, and operations continue after a brief application interruption during election. B. The team temporarily operates without a leader and enters a suspended state. The team continues to control network devices and communicate with applications but cannot receive configuration changes. C. The team temporarily operates without a leader and enters a suspended state It can continue to communicate with applications but cannot send new flows to network devices. D. The team elects one of the remaining controllers as the new leader. The team continues to control network devices but cannot receive new flows from applications.

Correct Answer: C

QUESTION NO: 4
A company has an HP Network Protector SDN Application solution that controls HP 5406R zl2 switches. Why should the network administrator ensure that HP switches use service insertion tunnels, rather than OpenFlow, to send traffic to the HP VAN SDN Controller?

A. because the service insertion tunnels provide faster failover capabilities B. because the service insertion tunnels provide stronger security C. because the service insertion tunnels provide per packet statistics D. because the service insertion tunnels provide a higher packet_in rate

Correct Answer: D

QUESTION NO: 5
new aces HP Network Optimizer SUN Application improve quality for Microsoft Lync traffic?

A. It uses deep packet inspection (DPI) analysis to identify voice and video traffic; it then dynamically configures switches to prioritize this traffic. B. It is pre-programmed with the correct sets of TCP and UDP ports for Lync traffic; it automatically deploys the correct QoS maps to controlled switches. C. It configures Lync clients to automatically prioritize their traffic correctly, and it configures switches to trust this prioritization. D. It dynamically configures controlled switches to prioritize the voice and video traffic flows based on session information from the controller.

Correct Answer: A

QUESTION NO: 6
A switch is configured to support OpenFlow 1.0 and 1.1. What happens when the switch sends an OpenFlow hello message to a standalone HP VAN SDN Controller 2.5?

A. The controller and switch will use OpenFlow 1.0. B. The controller requires all switches in the same VLAN to use OpenFlow 1.1. C. The controller responds with an error message because the controller does not support
OpenFlow 1.1. D. The controller uses OpenFlow 1.3. which is backwards compatible

Correct Answer: A

QUESTION NO: 7

The network administrator is setting up a controller team.
The team address is 192.168.100.100, and the three controllers are using 192.168.100.110, 192.168.100.111 and 192.168.100.112.
The administrator is configuring a switch with only basic IP connectivity that can reach the controller team.
The administrator starts to configure a new OpenFlow instance by using the commands shown in the exhibit.
The instance fails to activate.
How should the administrator change the configuration to enable it to activate?

A. Change the default setting for controller mode from single to team. B. Move to the appropriate VLAN context and add the OpenFlow instance. C. Change the IP address for all controllers to the team address. D. Add one or more VLANs to the OpenFlow instance.

Correct Answer: B
