NEW QUESTION # 28
You are finalizing a proposal for a data center network consisting of 14 CX 8325 switches, 6 CX
6300M switches, and Fabric Composer licenses for those switches. What is one assumption that you might include in the assumptions documentation?
Answer: A
Explanation:
Aruba Fabric Composer is deployed as a virtual appliance, so the proposal can reasonably document an assumption that the customer has suitable virtualization resources and OOBM connectivity available.
NEW QUESTION # 29
You are planning a pair of CX switches to act as ToR switches. The switches implement VSX as part of a data center L2 topology and connect to the core on VSX LAGs. To meet expansion requirements, you need to keep as many ports open as possible. What option should you recommend for VSX LAGs?
Answer: C
Explanation:
VSX keepalives should use an independent path from the ISL. Using the OOBM management interface preserves front-panel data ports while still providing a separate keepalive path.
NEW QUESTION # 30
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 # 31
What is an advantage of using a VSX-pair instead of two discrete switches to connect servers, storage, firewalls, and other workloads?
Answer: A
Explanation:
A VSX pair allows downstream devices such as servers, storage, and firewalls to connect with active-active LAGs across two physical switches, improving redundancy without requiring the endpoint to run a complex HA protocol.
NEW QUESTION # 32
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: B
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.
