Free HP HPE7-A12 Exam Dumps Questions & Answers

You are brought in to a customer with 1,115 employees to update the network and the previous network manager has left the company. What are methods to validate the current network state when the available network documentation is not up-to-date? (Choose two.)

• A.Use neighbor discovery protocols to learn neighbor relationships, document the connections and build a topology from the learned information.
• B.Documenting existing network configuration and topology is not required. Previous iterations of network designs are considered obsolete and the best practice is that new designs are 'clean- sheet' designs.
• C.Physically examine the network devices and trace the cables from device to device documenting the connections and cabling type.
• D.Begin searching through file shares for old documentation and compare the files and drawings to each other.
• E.Interview random company staff to gather the 'tribal knowledge' of how the network functions during normal operations and degraded states.

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.
Waratah Hospital requires a high availability deployment of Aruba Fabric Composer. How many nodes are supported with the high availability option?

• A.two nodes
• B.four nodes
• C.high availability is not supported
• D.three nodes

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

What is a key advantage of an active-active dual-homed server NIC design using VSX/MC-LAG at the access layer compared to active-standby NIC teaming?

• A.It eliminates the need for redundant switches entirely
• B.It is only supported on 1G links
• C.It requires no additional switch configuration
• D.It doubles the available bandwidth to the server under normal conditions and provides faster failover

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.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.
• B.The custOMER should place the iSCSI adapters in a PVLAN isolated VLAN to ensure traFFIC is forwarded without disruption from VM traffic.
• C.CX 10000 switches do not implement east-west firewall policies on traffic in a no-drop PFC queue.
• D.The customer should place the iSCSI adapters in a PVLAN primary VLAN to ensure trafFIC Is permitted.
