    B. Use separate IP per NSX Manager appliance per rack.
    C. Use another NSX Manager IP in case an appliance fails.
    D. Deploy a single active NSX Manager appliance in rack 1.
    E. Deploy an NSX Manager Appliance per rack and cluster them.
    F. Use a physical/internal load-balancer with the cluster.

  • Question 4:

    An architect is helping an organization with the Conceptual Design of an NSX-T Data Center solution. This information was gathered by the architect during the Discover Task of the Engagement Lifecycle: There are applications which use IPv6 addressing.

    Network administrators are not familiar with NSX-T Data Center solutions.

    Hosts can only be configured with two physical NICs.

    There is an existing management cluster to deploy the NSX-T components.

    Dynamic routing should be configured between the physical and virtual network.

    There is a storage array available to deploy NSX-T components.

    Which risk was documented by the architect? (Choose the best answer.)

    A. Network administrators are not familiar with NSX-T Data Center solutions.
    B. Dynamic routing should be configured between the physical and virtual network.
    C. There are applications which use IPv6 addressing.
    D. There is a storage array available to deploy NSX-T components.

  • Question 5:

    A. Any solution should add more value to current and future customers engagements.
    B. The design should offer agility and freedom for application phases.
    C. All application servers have hardcoded IP addresses.
    D. Current business continuity and disaster recovery plans are based on tape technology.
    E. Different vendors are used for the storage solution.

  • Question 6:

    An architect is designing a solution for containerization. The solution will include high availability and security using NSX-T Data Center. The architect plans to provide a basic required components list in the Logical Design. Which solution should the architect recommend? (Choose the best answer.)

    A. 3 NSX Managers, 3 virtual NSX Edges, two Tier-0 gateways in Active/Standby, BGP configuration
    B. 2 NSX Managers, 2 virtual NSX Edges, one Tier-0 gateway, BGP configuration and a static route
    C. 3 NSX Managers, 3 virtual NSX Edges, one Tier-0 gateway and a static route and OSPF
    D. 1 NSX Manager, 2 virtual NSX Edges, two Tier-0 gateways in Active/Active, BGP configuration

  • Question 7:

    Which selection must be taken into consideration when creating a Logical Design for a planned migration? (Choose the best answer.)

    A. An N-VDS can only attach to a single Overlay transport zone.

    C. An N-VDS can attach to both an Overlay and a VLAN transport zone to a N-VDS having different name/s.
    D. An N-VDS must be disabled before attaching both Overlay and VLAN transport zones.

  • Question 8:
