NEW QUESTION # 57
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.
In this scenario, the customers servers are HPE Servers. For the iLO ports, you propose a 6300M switch for each rack. What is the best practice to connect these switches to the data center data plane?
Answer: D
Explanation:
iLO/OOB management should remain on the out-of-band management network, separate from the production data plane.
NEW QUESTION # 58
You are presenting the proposed solution to the customer. The customer required micro- segmentation to be implemented so you designed the network to use the Aruba CX 10000 DSS.
The customer has questions about the implementation of PVLAN. What is a true statement about PVLAN that will help the customer understand the fundamentals of micro-segmentation?
Answer: B
Explanation:
In PVLAN design, regular endpoints should be placed in secondary VLANs, such as isolated or community VLANs. The primary VLAN is typically for promiscuous/default-gateway connectivity and can bypass the intended endpoint isolation.
NEW QUESTION # 59
Refer to the exhibit.
You are designing a data center network. This customer requests that you connect the data center to campus core switches. The customer uses VLANs for segmentation, but not VRFs.
What is the recommended design for the links between the data center core switches and the campus core switches?
Answer: C
Explanation:
The recommended campus-to-data-center core connection is Layer 3 routed links. Since the customer does not use VRFs, each physical link can be a simple point-to-point routed port using a /31 subnet.
NEW QUESTION # 60
What is the primary benefit of using EVPN as the control plane for a VXLAN overlay, compared to traditional flood-and-learn VXLAN?
Answer: A
Explanation:
EVPN leverages MP-BGP to advertise MAC and IP host routes proactively between VTEPs, avoiding the flooding and slow convergence associated with traditional flood-and-learn VXLAN. It still requires an underlay and VTEPs, and works with both IPv4 and IPv6.
NEW QUESTION # 61
You have delivered a CX 10000-based data center network to a customer. The customer wants to ensure a smooth transition to the new network before starting to implement the security capabilities. What should you recommend for the initial deployment?
Answer: A
Explanation:
For an initial CX 10000 deployment, disabling strict firewall mode allows traffic to pass while the customer validates network connectivity before gradually implementing segmentation/security policies.
