HPE Network Data Center Professional Architect Exam Sample Questions (Q57-Q62):

NEW QUESTION # 57
What is an advantage of using a VSX-pair instead of two discrete switches to connect servers, storage, firewalls, and other workloads?

A. You can save half the number of licenses needed for AFC.
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 only need to configure a single routing control-plane.

Answer: C

Explanation:
A VSX pair allows downstream devices such as servers, storage, and firewalls to connect with active-active LAGs across two physical switches, improving redundancy without requiring the endpoint to run a complex HA protocol.

NEW QUESTION # 58
What are important characteristics to mention while discussing possible connections for VMware hosts to server-access-switches?

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

Answer: C

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 # 59
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 Isolated 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 is generally not recommended for endpoints because they can communicate freely with all endpoints on the secondary VLANs.

Answer: D

Explanation:
In PVLAN design, regular endpoints should be placed in secondary VLANs, such as isolated or community VLANs. The primary VLAN is typically for promiscuous/default-gateway connectivity and can bypass the intended endpoint isolation.

NEW QUESTION # 60
Waratah Hospital, based in Australia, is planning to move many data center services to new facility. (The remaining legacy data center will not be part of this project.) Waratah Hospital hired an external consultant to assist with the new data center network design.
Based on the requirements for the data center network infrastructure, the external consultant has created a high-level design. The below summarizes the content of the design document.
Requirements and information:
- Six racks in the data center room (single row).
- Redundant Top of Rack leaf switches with back-to-front cooling in each rack, providing 10/25 Gbps connectivity to servers, storage, and other devices.
- Four 100 GbE uplinks per leaf switch.
- The customer requested to install all switch ports facing the back of the rack racks (hot aisle.)
- OOB management for servers, storage, and network has to be provided through an external switch with back-to-front cooling. This switch has to be included in the solution. One OOB switch provides connectivity for two racks.
- Core equipment for the OOBM network is being reused.
- Middle-of-row spine switches.
-The data center should connect to the hospital building with links that provide 400 Gbps.
- Internet access is provided through an existing firewall cluster with two firewalls, each firewall in one data room. The second firewall is operating in standby mode, VRRP is utilized on the firewalls for failover. The data center network should connect to these firewalls with links that total
100 Gbps.
- The external link is a dark fiber direct link based on single-mode fiber (OS2). The distance to the main hospital 1.5 KM. The links will terminate on two core switches in the hospital.
The customer also requires:
- 99.999% uptime for this life-critical environment.
- Planned and unplanned downtime has to be minimized.
- Software upgrades are only allowed once per year with close to zero downtime.
- All life-critical resources are accessed locally, and all resources exist within the hospital campus.
- Waratah Hospital requires a highly secure environment for the data center. Encrypted wire speed connectivity between the data room and the hospital is a must-have because the link between the buildings crosses a public road.
- Waratah Hospital has a mix of virtualized (vSphere) servers. Nutanix storage, bare metal servers, backup servers and other devices.
In the past, the hospital has had a security breach that resulted in data loss, network downtime, and identity theft.
Refer to the scenario. You are trying to decide between the CX 9300 and CX 8325 switches for the border leaf switches. What is a hard requirement for this customer that affects this decision?

A. The mixed speed requirements to connect to both the hospital and the internet firewall
B. The bandwidth requirements on the links to the hospital
C. The need to minimize downtime during software upgrades
D. Hardware encryption on the links to the hospital

Answer: D

Explanation:
The scenario states that encrypted wire-speed connectivity is a must-have because the link crosses a public road.

NEW QUESTION # 61
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 OOBM network
C. In the cloud with access to any overlay VRF to which policies will be applied
D. In the network underlay

Answer: B

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.
