NEW QUESTION # 43
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.
What are valid assumptions that can be made for this scenario when creating the network design documentation? (Choose two.)
Answer: A,C
Explanation:
It is valid to document assumptions that sufficient virtualization resources will exist for required software and that sufficient inter-site cabling will be available for the design.
NEW QUESTION # 44
A customer is upgrading their data center structured cabling to SMF. At the same time 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: D
Explanation:
The CX 9300-32D is appropriate as a 100/400GbE spine and supports breakout use cases, while
4x100G DR QSFP-DD supports SMF and lets the spine connect to current 100GbE leaves during migration to 400GbE.
NEW QUESTION # 45
Drag and Drop Question
Match the switch family with the capability.
Answer:
Explanation:
Explanation:
CX 9300 supports high-density 400G/100G breakout designs, CX 8360 uses Aruba Gen7 ASIC, CX 10000 provides Pensando-powered distributed services, and CX 6405 is a modular chassis platform with redundant management module support.
NEW QUESTION # 46
A customer's security team requires micro-segmentation down to the individual workload level within the data center. Which technology combination best satisfies this requirement in an Aruba CX + VMware environment?
Answer: B
Explanation:
NSX's distributed firewall enforces security policy at the vNIC/workload level regardless of physical topology, while the CX VXLAN/EVPN fabric provides the underlying transport. VLANs alone can't achieve workload-level granularity, physical firewalls per server pair are impractical, and disabling east-west traffic breaks application functionality.
NEW QUESTION # 47
Your customer wants to host endpoints on the Border Leaf switches. Is this a supported topology?
Answer: C
Explanation:
A border leaf can still function as a leaf switch and host endpoint VLANs/SVIs, while also providing external connectivity for the fabric.
