Question 2 of 57

Which three IPv6 features are supported in an NSX-T Data Center design? (Choose three.)

Answer choices
Show answer

Correct answers: B, E, F

The three IPv6 features supported in an NSX-T Data Center design are IPv6 static routing, IPv6 Distributed Firewall, and IPv6 VXLAN. IPv6 static routing is a fundamental routing method supported by NSX-T. The IPv6 Distributed Firewall feature allows the implementation of security policies for IPv6 traffic. Lastly, while traditional VXLAN does not inherently support IPv6, NSX-T has incorporated support for IPv6 VXLAN. IPv6 OSPF is not a typical feature in NSX-T designs, IPv6 switch security is a vague term that doesn't specify a clear feature, and IPv6 DNS is generally handled outside the scope of NSX-T designs.

Question 3 of 57

An architect is helping an organization with the Physical Design of an NSX-T Data Center solution.

This information was gathered during a workshop:

  • Some workloads should be moved to a Cloud Provider.
  • Extend network's VLAN or VNI across sites on the same broadcast domain.
  • Enable VM mobility use cases such as migration and disaster recovery without IP address changes.
  • Support 1500 byte MTU between sites.

Which selection should the architect include in their design? (Choose the best answer.)

Answer choices
Show answer

Correct answer: D

An L2 VPN allows the extension of Layer 2 networks across different sites, effectively creating a single broadcast domain. This enables VM mobility use cases without the need for IP address changes and supports seamless migration and disaster recovery scenarios. Additionally, it supports the requirement for a 1500 byte MTU between sites, ensuring compatibility across the network.

Question 4 of 57

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.)
Answer choices
Show answer

Correct answer: C

The virtual switch design that should be recommended involves creating an NSX-T Virtual Distributed Switch (N-VDS) for both Management VMKernel and overlay traffic and assigning both NICs. This approach ensures that there is no single point of failure by utilizing both available 10Gb NICs, which corresponds to redundancy and higher availability, aligning with the requirement that there should be no single point of failure in the proposed design.

Question 5 of 57

What selection is the key design benefit provided by a dedicated Edge Cluster VM or Bare Metal? (Choose the best answer.)

Answer choices
Show answer

Correct answer: B

A dedicated Edge Cluster VM or Bare Metal solution ensures predictable network performance because it eliminates contention for resources typically seen in a shared virtual environment. With dedicated hardware, the network services such as routing and firewalling can operate without interference from other workloads, leading to consistent performance and reliability. This predictability is crucial for applications that demand stable and reliable network performance.

Stories from the certified

As this was my first certification exam, I was understandably nervous about what to expect. These study materials made the preparation process much easier, and many of the questions closely reflected those on the actual exam.

Wasted about a month going through the free dump sites scattered all over reddit, half the answers were wrong and the other half were for a version of the exam that doesn't even exist anymore. Eventually gave in and paid the small fee here, and the difference was night and day.

Honestly, I had already gone through the official documentation quite thoroughly, but still didn't feel fully confident going in. This helped things finally click for me. I realized I knew the material, but just hadn't connected all the pieces yet.

Used this along with Microsoft Learn and the combo worked really well. The practice questions made the stuff I'd read actually stick. Passed first attempt, no complaints from me.

I don't usually leave reviews, but this one felt worth sharing. The questions were quite close to what actually appeared on the exam, more than I expected. I spent about a week going through the material before my test, and it helped me feel more prepared.
