NEW QUESTION # 15
You delivered an L3 spine and leaf topology to a customer several years ago. The solution consisted of two CX 8325-32C switches at the spine and 20 CX 8325-48Y8C leaf switches. The leaf switches operate as 10 VSX pairs. The customer would now like to double the forwarding capacity of the topology. What should you recommend?
Answer: C
Explanation:
The current design has 2 spine switches, with each leaf connecting to each spine. Adding 2 more spines doubles the number of ECMP spine paths and therefore doubles the leaf-to-spine forwarding capacity, while staying within CX 8325-32C port limits.
NEW QUESTION # 16
What is the best practice for using VSX at the Core of a two-tier design?
Answer: A
Explanation:
In a two-tier L2 access design, VSX at the core provides redundant active-active connectivity and default gateway resiliency for access switches. For L3-only or EVPN-VXLAN access designs, routed spine/core behavior is preferred instead.
NEW QUESTION # 17
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 # 18
A customer has deployed CX 10000 switches. Fabric Composer, and Pensando Policy and Services Manager (PSM). The switches are discovered in PSM but no VRFs or networks are added. Now the customer wants to get started by applying micro-segmentation to one network.
The customer tells you that they plan to add a policy with rules for permitting desired traffic from endpoints in this network. They will apply it as an egress policy to the network. At this point they will not add any other networks to PSM or apply policies to them. What warning should you give the customer about this plan?
Answer: D
Explanation:
For CX 10000/PSM policy enforcement, networks in the same VRF should be consistently represented in PSM. Adding only one network can lead to incomplete policy context and unexpected segmentation behavior.
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.
Refer to the scenario. One of your junior colleagues has recommended deploying CX 8325-32C BF 6F 2AC Bundle switches for border leaf switches. What issue should you point out with this plan?
Answer: B
Explanation:
The hospital link has strict requirements for high-capacity, encrypted wire-speed connectivity, so the proposed border leaf choice must be validated against that requirement.
