At this time, people should to need some good study materials. Not only will our study materials help you pass exam, but it will also save your valuable time. Now let me introduce our HPE7-A12 exam questions to you in detail.

DOWNLOAD DEMO

Multiple versions available

Unlike other study materials, there is only one version and it is not easy to carry. Our HPE7-A12 exam questions mainly have three versions, as long as you have mobile electronics, you can learn anywhere at any time. Now, let me introduce you to our three versions. The first one is PDF version, it is very easy for you to download PDF, and it has two ways to use. On the one hand, you can browse and learn our HPE7-A12 learning materials directly on the Internet. On the other hand, you can print it on paper so you can take notes. The second one is software version: this version can simulate a real test environment, which allows you to test the effect of using our HPE7-A12 preparation practice. The third one is the APP version: it has the functions of mock test, timed test and online correction. And the most important thing is that these three versions are unlimited in number and frequency. You can choose the version you like to study to get the HP certification.

The product quality can be guaranteed

If you compare the test to a battle, the examinee is like a brave warrior, and the good HPE7-A12 learning materials are the weapon equipments, but if you want to win, then it is essential for to have the good study materials. Our study materials are of high quality which is carefully prepared by professionals based on the changes in the syllabus and the latest development in practice. Our HPE7-A12 preparation practice are highly targeted and have a high hit rate, there are a lot of learning skills and key points in the exam, even if your study time is very short, you can also improve your HPE7-A12 exam scores very quickly. Even if you have a week foundation, I believe that you will get the certification by using our study materials.

HPE Network Data Center Professional Architect Sample Questions:

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

2. You delivered an L3 spine and leaf topology to a customer several years ago. The solution consisted of two CX 8325-32C switches at the spine and 20 CX 8325-48Y8C leaf switches. The leaf switches operate as 10 VSX pairs. The customer would now like to double the forwarding capacity of the topology. What should you recommend?

A) Upgrading the existing links to 200 GbE
B) Adding two more spine switches that connect to each leaf switches with 100 GbE links
C) Add two more 100GbE links between each leaf switch and spine switch
D) Adding one more spine switch that connects to each leaf switch with two 100 GbE links

3. 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.
In this scenario, the customers servers are HPE Servers. For the iLO ports, you propose a 6300M switch for each rack. What is the best practice to connect these switches to the data center data plane?

A) You should connect these switches to the border leaf.
B) You shouldn't connect these switches to the data center data plane.
C) You should connect to the ToR switches in each rack.
D) You should connect these switches to the spine.

4. You have been called in to help design an HPE Aruba Networking CX network solution to connect AI servers to file storage. The solution must support NFS over RDMA and provide 400 GbE links to the edge. The design currently consists of leaf and spine switches, which carry all traffic in VXLAN tunnels. Each switch is a CX 9300-32D switch. What is one correction that you should make to the design?

A) Redesign the solution to carry traffic without VXLAN to ensure support for DCB
B) Replace the CX 9300-32D switches with CX 9300S switches to ensure support for RoCEv1/v2
C) Eliminate the spine to establish a rail-only topology
D) Continue to use CX 9300-32D switches for the spine but use CX 9300S switches as leaf switches to optimize costs

5. You are designing an L3 spine and leaf topology that uses CX switches. Those switches implement EVPN VXLAN. The customer does not require VRF segmentation for any of the data center endpoint traffic. What should you recommend for the VRF in which to place the SVIs for server, VM and other endpoint VLANs?

A) Use whichever VRF the switch individual loopback interface is attached to
B) Use the default VRF
C) Use whichever VRF the switch VXLAN loopback interface is attached to
D) Use any VRF name except default
