During a design workshop, the customer states their applications are highly sensitive to latency and jitter, such as real-time market data feeds. What design change might you propose?

• A. Implement a non-blocking, low-latency spine-leaf fabric with minimal oversubscription and hardware timestamping/PTP support if needed
• B. Reduce the number of spine switches to simplify the topology
• C. Use store-and-forward switches exclusively to guarantee accuracy over speed
• D. Add additional aggregation tiers to increase path diversity

You are designing an L3 spine and leaf topology that uses CX switches. Those switches implement EVPN VXLAN. The customer does not require VRF segmentation for any of the data center endpoint traffic. What should you recommend for the VRF in which to place the SVIs for server, VM and other endpoint VLANs?

• A. Use whichever VRF the switch VXLAN loopback interface is attached to
• B. Use the default VRF
• C. Use any VRF name except default
• D. Use whichever VRF the switch individual loopback interface is attached to

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.)

• A. power requirements
• B. connectivity requirements
• C. heat dissipation requirements
• D. switch placement requirements

What is the correct statement with regard to flow synchronization on the HPE Aruba Networking CX 10000 Distributed Services Modules (DSM) operating in VSX?

• A. Flow state on the DSMs is not synchronized between the VSX members.
• B. Flow state on DSM1 of a VSX member is synchronized to DSM2 on the other VSX member.
• C. Flow state on DSM1 of a VSX member is synchronized to any DSM on the other VSX member.
• D. Flow state is synchronized between the matching DSMs between the VSX peers.

During requirements gathering, the customer's application owner states RTO must be under 60 seconds for a critical database cluster. Which network-level design decision most directly supports this requirement?

• A. Increasing the ARP cache timeout to reduce protocol overhead
• B. Relying solely on manual failover procedures
• C. Using default STP timers throughout the fabric
• D. Using fast-converging protocols (e.g., BFD with routing protocols, sub-second VSX failover) and minimizing L2 dependency for that segment
