VMware Advanced Design VMware NSX-T Data Center Sample Questions:
An architect is helping an organization with the Physical Design of an NSX-T Data Center solution.
This information was gathered during a workshop:
There are six hosts and hardware has already been purchased.
Customer is planning a collapsed Management/Edge/Compute cluster.
Each host has two 10Gb NICs connected to a pair of switches.
There should be no single point of failure in any proposed design.
Which virtual switch design should the architect recommend to the organization? (Choose the best answer.)
- A. Create an NSX-T Virtual Distributed Switch (N-VDS) for Management VMkernel and overlay traffic and assign a new virtual NIC.
- B. Create an NSX-T Virtual Distributed Switch (N-VDS) for Management VMKernel and overlay traffic and assign both NICs.
- C. Create an NSX-T Virtual Distributed Switch (N-VDS) for Management VMkernel traffic and assign one NIC. Also, create an NSX-T Virtual Distributed Switch (N-VDS) for overlay traffic and assign one NIC.
- D. Create a vSphere Distributed Switch (vDS) for Management VMkernel traffic and assign one NIC. Also, create an NSX-T Virtual Distributed Switch (N-VDS) for overlay traffic and assign one NIC.
Correct Answer: B 🗳️
A customer has a requirement to implement a next generation firewall (NGFW) to improve security network introspection. The customer wants to apply the NGFW to all workloads exposed both internally and externally. The customer wants the NGFW to work seamlessly with NSX-T Data Center and vSphere.
Which solution should be recommended to the customer? (Choose the best answer.)
- A. Use network introspection only on the external workloads and use NSX DFW for internal workloads.
- B. Apply the NGFW to internal and external workloads for increased protection and use NSX-T Data Center with Federation to set network policies.
- C. Apply the NGFW on bare metal hosts which will offer better performance of inline network introspection.
- D. Use NSX-T Data Center leveraged with NSX Intelligence to protect all workloads at the network inspection level.
Correct Answer: A 🗳️
