NEW QUESTION # 57
You are sizing spine switches for a new leaf-spine fabric supporting 48 leaf switches, each with two 100G uplinks. What is the minimum number of 100G ports required per spine switch if there are 4 spine switches and full redundancy is desired?
Answer: C
Explanation:
Each leaf has 2 uplinks distributed across 4 spines (1 uplink to 2 of the 4 spines, or evenly spread), so each spine needs to support 48 leaves ÷ 4 spines × 2 uplinks = 24 ports per spine to provide full connectivity and redundancy.
NEW QUESTION # 58
You have designed an L3 spine and leaf topology for a customer's data center which is highly virtualized with VMware vSphere. This customer already uses HPE Aruba Networking mobility and switching solutions in the campus. You are recommending CX 8325 and CX 9300 switches and Fabric Composer The customer asks you to justify the cost of the Fabric Composer licenses.
What should you explain?
Answer: D
Explanation:
Fabric Composer provides VMware vSphere integration and automation for data center fabric operations, including simplifying/automating VLAN and network provisioning.
NEW QUESTION # 59
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: B
Explanation:
Fabric Composer high availability uses a three-node deployment model.
NEW QUESTION # 60
Hotspot Question
Click where you would implement the CX 10000 network segmentation policy in this data center deployment.
Answer:
Explanation:
Explanation:
Network segmentation/microsegmentation for server workloads is implemented at the CX 10000 ToR enforcement points, closest to the workloads. The edge gateway is for north-south/WAN edge services, not the primary workload segmentation policy placement.
NEW QUESTION # 61
Which factor should most influence the decision to use a two-tier (spine-leaf) versus a three-tier (spine-super spine-leaf) fabric design?
Answer: D
Explanation:
When the required scale exceeds what a single spine tier can support (i.e., more leaf switches than available spine ports allow), a super-spine tier is introduced to interconnect multiple spine- leaf "pods," forming a three-tier design. Scale, not aesthetics or unrelated org details, drives this decision.
