NEW QUESTION # 107
During discovery, you learn the customer's current data center has no automation and all changes are made via CLI on individual switches. What follow-up Qis most important for scoping the design?
Answer: A
Explanation:
Understanding whether the customer wants to move toward automated, intent-based fabric management directly affects switch model selection, licensing, and overall architecture. The other options are irrelevant to design scope.
NEW QUESTION # 108
You are designing an L3 spine and leaf topology that uses CX switches. Those switches implement EVPN VXLAN with a distributed gateway model. You are helping implementers to assemble a list of required loopback interface IDs and IP blocks. What information do you need from the customer to complete this list?
Answer: B
Explanation:
The choice of single-AS versus dual-AS affects the BGP control-plane configuration and AS numbering, not principally the required loopback inventory. Distributed-gateway designs can require dedicated per-VRF loopback addressing for services such as DHCP relay and unique source addressing. HPE also recommends planning an IP block for the loopbacks assigned to each overlay VRF.
NEW QUESTION # 109
Which two questions should be asked to properly size the data center fabric's east-west bandwidth requirements? (Choose two.)
Answer: D,E
Explanation:
Understanding the east-west to north-south traffic ratio and the intended server-to-leaf oversubscription ratio are both essential inputs for sizing spine and leaf uplink bandwidth correctly. The remaining options are irrelevant to fabric sizing.
NEW QUESTION # 110
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?
Answer: D
Explanation:
Fabric Composer high availability uses a three-node deployment model.
NEW QUESTION # 111
A customer's data center uses structured cabling based on MMF O'5. The customer wants to upgrade the spine switches in their spine and leaf topology. A key goal of this upgrade is to eventually support 400GbE leaf-to-spine links. However, for a while, many of the leaf switches will continue to support 100GbE uplinks. What is a valid recommendation for the spine switches?
Answer: B
Explanation:
With existing MMF OM5 structured cabling, 400G QSFP-DD MPO-16 optics are the valid migration choice for 400GbE spine links. The 4x100G DR option is for single-mode fiber, not MMF.
