NEW QUESTION # 66
You are delivering a data center network based on CX 8360 switches. The network uses a spine and leaf topology and EVPN VXLAN. Not long before the deployment the customer comes with a new requirement. In one server rack the customer hosts servers for different tenants. The leaf switches in that rack must be able to reuse the same VLAN IDs for different logical L2/L3 domains. What should you explain?
Answer: D
Explanation:
VLAN translation lets the leaf switches reuse the same customer-facing VLAN IDs for different tenants by translating them to unique internal VLAN/VNI mappings in the EVPN-VXLAN fabric.
NEW QUESTION # 67
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: A
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 # 68
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.
Given the scenario, which environmental requirements are provided in this scenario? (Choose two.)
Answer: A,E
Explanation:
The scenario provides switch placement requirements and airflow direction, including back-to- front cooling and ports facing the hot aisle.
NEW QUESTION # 69
You have designed an L3 spine and leaf topology for a customer's data center which is highly virtualized with VMware vSphere. This customer already uses HPE Aruba Networking mobility and switching solutions in the campus. You are recommending CX 8325 and CX 9300 switches and Fabric Composer The customer asks you to justify the cost of the Fabric Composer licenses.
What should you explain?
Answer: A
Explanation:
Fabric Composer provides VMware vSphere integration and automation for data center fabric operations, including simplifying/automating VLAN and network provisioning.
NEW QUESTION # 70
To prepare for a data center network implementation, you have asked a customer for a list of VLANs to support. The customers list for several VMware ESXi hosts includes 4095. What follow up question should you ask?
Answer: A
Explanation:
In VMware ESXi, VLAN ID 4095 on a port group means VLAN trunking/VGT, allowing guest VMs to tag traffic themselves. You need to identify the actual VLAN tags used by those VMs.
