NEW QUESTION # 93
A customer's compliance team requires that PCI-scoped systems be logically isolated from the rest of the data center, with all inter-zone traffic inspected. Which design element addresses this requirement?
Answer: C
Explanation:
VRF (or overlay-based) segmentation logically isolates the PCI-scoped systems, and routing all inter-VRF traffic through a firewall/service insertion point ensures it is inspected, satisfying the compliance requirement. MTU and STP settings do not address segmentation or inspection requirements.
NEW QUESTION # 94
To secure the network, which feature or capability should be implemented?
Answer: D
NEW QUESTION # 95
A customer wants to migrate from a traditional VLAN-based data center network to a VXLAN/EVPN fabric with minimal disruption. What is an appropriate first step in the design process?
Answer: B
Explanation:
Migrations should minimize disruption; a border leaf function bridges legacy VLAN-based segments into the new VXLAN/EVPN fabric so services can be migrated incrementally. EVPN is the standard control plane for VXLAN and should not be skipped, since it provides MAC/IP learning and reduces flood-and-learn behavior.
NEW QUESTION # 96
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 rack requirements in the scenario. Which additional information can help you choose between CX 8325-48Y8C and CX 8360-48Y6C models?
Answer: C
Explanation:
The scenario gives 10/25GbE requirements, but the exact current and future port-speed mix helps validate the best ToR model.
NEW QUESTION # 97
Identify the documentation resources for finding validated information that assists the architect in designing the solution (Choose two.)
Answer: B,C
Explanation:
Architects should rely on validated vendor documentation such as configuration guides for supported designs/settings and data sheets for product capabilities, specifications, and limits.
