NEW QUESTION # 15
You are proposing HPE Aruba Networking Central for a customer. Which customer requirement can only be fulfilled by AAS license, as opposed to an AAE license?
Answer: B
Explanation:
AAS/aaS SKUs provide flexible consumption options such as license co-termination, which lets licenses purchased at different times align to a common end date.
NEW QUESTION # 16
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?
Answer: A
Explanation:
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.
NEW QUESTION # 17
A customer running VMware with NSX asks whether they still need to design VLANs on the physical CX switches. What is the correct guidance?
Answer: D
Explanation:
Even with NSX handling overlay segmentation for workloads, the physical underlay still requires basic VLANs/subnets for functions like VTEP/transport connectivity and out-of-band management; NSX segments do not need to map one-to-one with physical VLANs, and a pure L2 underlay is not required (a routed underlay is typically preferred).
NEW QUESTION # 18
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?
Answer: D
Explanation:
NFS over RDMA/RoCE requires lossless Ethernet behavior with DCB features such as PFC/ETS and ECN. For CX 9300-based RoCE designs, ECN is supported in the underlay, not in the VXLAN overlay, so RDMA storage traffic should not be carried through VXLAN tunnels.
NEW QUESTION # 19
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.
Given the scenario, what environmental information should be gathered to complement the design? (Choose two.)
Answer: A,B
Explanation:
Heat dissipation and power requirements are environmental details that still need to be validated for the physical deployment.
