HPE Network Data Center Professional Architect Exam HPE7-A12 Prüfungsfragen mit Lösungen (Q24-Q29):

24. Frage
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 have learned that the customer needs to extend two VRFs between the new data center network and the firewall. To meet with the requirements of the scenario and general best practices, what should you recommend for connecting border leaf switches to the hospital core?

A. One VSX LAG that includes a full mesh of 25 GbE links between the border leaf switches and firewall cluster, two SVIs on the LAG.
B. 2x 25 GbE routed only ports between border leaf switch 1 and the active firewall 2x 25 GbE routed only ports between border leaf switch 2 and the passive firewall.
C. One VSX LAG to each firewall consisting of 25 GbE links on the border leaf switches, two SVIs on each LAG.
D. One 100 GbElink between border leaf switch 1 and the active firewall. One 100 GbE link between border leaf switch 2 and the passive firewall. Two subinterfaces on each link that act as ROPs.

Antwort: C

Begründung:
For two VRFs and an active/standby firewall pair, each firewall should have redundant VSX LAG connectivity with separate VLAN/SVI transit per VRF.

25. Frage
A customer has deployed CX 10000 switches. Fabric Composer, and Pensando Policy and Services Manager (PSM). The switches are discovered in PSM but no VRFs or networks are added. Now the customer wants to get started by applying micro-segmentation to one network.
The customer tells you that they plan to add a policy with rules for permitting desired traffic from endpoints in this network. They will apply it as an egress policy to the network. At this point they will not add any other networks to PSM or apply policies to them. What warning should you give the customer about this plan?

A. The customer should apply the egress policy at both the VRF and network level to ensure that it works properly.
B. An ingress policy not egress policy, is the correct direction for controlling traffic from endpoints.
C. When you apply a policy to one network, it is recommended to add all the networks in its VRF to PSM.
D. The customer must enable strict firewall mode before applying policies to ensure they take effect.

Antwort: C

Begründung:
For CX 10000/PSM policy enforcement, networks in the same VRF should be consistently represented in PSM. Adding only one network can lead to incomplete policy context and unexpected segmentation behavior.

26. Frage
You have successfully installed, configured, and migrated the customer to the new Aruba CX data center equipment. What documents are normally part of the post-installation deliverables?

A. Completed RFP Responses
B. Support entitlement QR codes
C. Equipment data sheets
D. Inventory

Antwort: D

Begründung:
Post-installation deliverables normally include updated as-built documentation such as device inventory, configurations, topology, and implementation details. Data sheets and RFP responses are pre-sales/design documents.

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

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

Antwort: C

Begründung:
In VMware ESXi, VLAN ID 4095 on a port group means VLAN trunking/VGT, allowing guest VMs to tag traffic themselves. You need to identify the actual VLAN tags used by those VMs.

28. Frage
You are finalizing a proposal for a data center network consisting of 14 CX 8325 switches, 6 CX
6300M switches, and Fabric Composer licenses for those switches. What is one assumption that you might include in the assumptions documentation?

A. The customer has an Internet connection over which switches' mgmt ports can receive access to the cloud-based management solution.
B. The customer has ESXi or KVM hosts that have sufficient resources to run Fabric Composer and can connect to the OOBM network.
C. The customer has attended or enrolled for training on using Fabric Composer.
D. The customer has sufficient OPEX budget to pay for the Fabric Composer licenses

Antwort: B

Begründung:
Aruba Fabric Composer is deployed as a virtual appliance, so the proposal can reasonably document an assumption that the customer has suitable virtualization resources and OOBM connectivity available.
