NEW QUESTION # 12
A customer is upgrading their data center structured cabling to SMF. At the same time the customer wants to upgrade the spine switches in their spine and leaf topology A key goal of this upgrade is to eventually support 400GbE leaf-to-spine links. However, for a while, many of the leaf switches will continue to support 100GbE uplinks. What is a valid recommendation for the spine switches?
Answer: A
Explanation:
The CX 9300-32D is appropriate as a 100/400GbE spine and supports breakout use cases, while
4x100G DR QSFP-DD supports SMF and lets the spine connect to current 100GbE leaves during migration to 400GbE.
NEW QUESTION # 13
You are modernizing a customer's legacy three-tier architecture with an L3 spine and leaf topology. The CX switches in the topology will provide the overlay. The customer data center uses six VRFs. The customer has asked for service leaf switches to connect to two clustered firewalls, which route and filter traffic between the VRFs. How should the service leaf switches connect to the firewalls?
Answer: C
Explanation:
Create one multi-chassis LAG to each firewall. Each LAG operates as a Layer 2 trunk carrying a separate transit VLAN for every VRF. HPE's validated border-leaf configuration uses two MC- LAGs-one to each firewall-with the external VRF VLANs permitted on both.
NEW QUESTION # 14
What is the correct statement with regard to flow synchronization on the HPE Aruba Networking CX 10000 Distributed Services Modules (DSM) operating in VSX?
Answer: A
Explanation:
In a CX 10000 VSX pair, firewall flows are synchronized across the logical VSX VTEPs, and DSM flow sync is done between matching DSMs, not randomly or cross-mapped between DSM1 and DSM2.
NEW QUESTION # 15
You are delivering a spine and leaf architecture based on 18 CX 8360-48Y6C v2 leaf switches and two CX 8325-32C spine switches. The leaf switches support servers with 10 and 25 GbE ports. Currently you are planning to use two 100 Gbps uplinks per leaf switch. The customer returns with the requirement to increase the uplink bandwidth by at least 50% per leaf switch.
What is a valid change to the plan?
Answer: C
Explanation:
Each leaf currently has 2 × 100GbE uplinks = 200Gbps. Adding a third spine with one 100GbE link from each leaf increases each leaf to 300Gbps, meeting the 50% increase requirement. The CX 8325-32C has enough ports to connect to all 18 leaves.
NEW QUESTION # 16
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. You are trying to decide between the CX 9300 and CX 8325 switches for the border leaf switches. What is a hard requirement for this customer that affects this decision?
Answer: D
Explanation:
The scenario states that encrypted wire-speed connectivity is a must-have because the link crosses a public road.
