HP HPE7-A12 valid study dumps : HPE Network Data Center Professional Architect Exam

To prepare for a data center network implementation, you asked a customer for a list of VLANs to support.
The customer's list for several VMware ESXi hosts includes 4095.
What follow-up question should you ask?

• A. Is VLAN 4095 associated with the same subnet on all of those hosts?
• B. Because this VLAN ID is reserved for the system on CX switches, is the customer open to changing that VLAN ID?
• C. Is the customer using NSX to support this non-standard VLAN?
• D. What VLAN tags do the VMs connected to the 4095 port group use?

Waratah Hospital, located in Australia, plans to move many data-center services to a new facility. (The remaining legacy data center is not included in this project.) Waratah Hospital has hired an external consultant to help design the new data-center network.
Based on the data-center network-infrastructure requirements, the external consultant has produced a high- level design. The following summarizes the design document.
Requirements and information:
Six racks in the data-center room (a single row).
Redundant top-of-rack leaf switches with back-to-front cooling in every rack, providing 10/25 Gbps connectivity to servers, storage, and other devices.
Four 100 GbE uplinks per leaf switch.
The customer requested that all switch ports face the back of the rack racks (hot aisle).
OOB management for servers, storage, and network must be provided through an external switch with back- to-front cooling. This switch must 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 must connect to the hospital building using links that provide 400 Gbps.
Internet access is supplied through an existing firewall cluster with two firewalls, with one firewall in each data room. The second firewall operates in standby mode, and VRRP is used on the firewalls for failover. The data-center network must connect to these firewalls using links totaling 100 Gbps.
The external link is a dark-fiber direct link based on single-mode fiber (OS2). The distance to the main hospital is 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 must be minimized.
Software upgrades are permitted only once per year with close to zero downtime.
All life-critical resources are accessed locally, and all resources reside within the hospital campus.
Waratah Hospital requires a highly secure data-center environment. Encrypted wire-speed connectivity between the data room and the hospital is mandatory 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 experienced a security breach that resulted in data loss, network downtime, and identity theft.
Given the scenario, which environmental requirements are stated? Choose two.

• A. available power to racks
• B. encrypted connectivity
• C. switch placement
• D. traffic micro-segmentation
• E. airflow direction

What is the recommended practice for using VSX at the core of a two-tier design?

• A. You should implement VSX at the core when the access switches implement EVPN VXLAN.
• B. You should implement VSX at the core when the access layer operates at layer 2 only.
• C. You should never implement VSX at the core of a two-tier design.
• D. You should implement VSX at the core when the access is layer 3 only with OSPF routed traffic forwarding between core and access.

You are upgrading a customer's legacy three-tier architecture to an L3 spine-and-leaf topology. The CX switches in the topology will supply the overlay. The customer data center uses six VRFs. The customer has requested service leaf switches that connect to two clustered firewalls, which route and filter traffic between the VRFs.
How should the service leaf switches be connected to the firewalls?

• A. On four ROPs (two per switch), each ROP being in the default VRF
• B. On two VSX LAGs, each of which carries one VLAN per VRF
• C. On four ROPs (two per switch), each ROP being attached to the six data center VRFs
• D. On two VSX LAGs, which are in the default VRF

You are designing an L3 spine-and-leaf topology using CX switches. The switches implement EVPN VXLAN. The customer does not need VRF segmentation for any data-center endpoint traffic.
What should you recommend for the VRF that contains the SVIs for server, VM, and other endpoint VLANs?

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