Question # 82

A Foundation install must be done on four NX nodes for a new customer. A consultant need to set up the network onsite before imaging the nodes through the Foundation tool.

The nodes are equipped with two SFP28 25GbE NICs with dual ports, and a 10GBase-T NIC with dual ports as well The customer’s ToR switches are 25GbE datacenter switches, already in production.

What is the appropriate hardware to perform the most reliable imaging of these NX nodes?

Options:

A.

A flat Ethernet switch, 4 compatible IGBase-T GBiCs, five Ethernet cables and a laptop.


B.

The 25GbE production switches. 4 DAC cables and 5 Ethernet cables with a flat Ethernet switch, and a laptop.


C.

A flat Ethernet switch. 9 Ethernet cables, and a laptop.


D.

The 25GbE production switches. 4 DAC cables, only one Ethernet cable with a 10GBase-T GBIC, and a laptop.

Questions # 85:

A VM does not have enough resources for the demand, which leads to performance bottlenecks. The VM is exhibiting one or more of following baseline values, based on the past 30 days:

• CPU usage > 90% (moderate), 95% (high)

• CPU ready time > 5%, 10%

Options:

A.

Constrained VM


B.

Bully VM


C.

Inactive VM


D.

Over-provisioned VM


Questions # 86:

An administrator of a Nutanix Enterprise Cloud has microsegmentation enabled and a firewall VM installed. The security team notifies the administrator that one of the VMs hosted in the environment has been exhibiting suspect network activity. The administrator wants to isolate the VM from the production network, but must still be able to access it to perform diagnostics.

What should the administrator do to meet the requirement?

Options:

A.

Disable the vNIC on the affected VM


B.

Quarantine the VM using the Forensic Method


C.

Create a firewall rule that blocks VM traffic but permits diagnostic access


D.

Create a security policy with a service chain directing that VMs traffic to the firewall VM


Questions # 87:

◦Take advantage of all available 10G links

◦Achieve maximum throughput per VM

◦Use of redundant ToR switches

◦Fastest reconvergence during link failure

How should the load balancing be configured on the host?

Options:

A.

In Prism Element, update the virtual switch uplink configuration to Active-Active with MAC pinning.


B.

In Prism Element, update the virtual switch uplink configuration to Active-Active.


C.

Use CLI to add the interfaces to bridge bro on all hosts.


D.

Use CLI to configure Balance-TCP on bridge bro.


Questions # 88:

B.

Set IP Addresses in CVM/Host subnet only.


C.

Set IP Addresses in both CVM/Host and IPMI subnets.


D.

Enable network segmentation.


Questions # 89:

An administrator manages the following two Nutanix AOS 5.15 cluster environment:

• Corp-cluster-01

• Corp-cluster-02

The VM images must be available only on Corp-cluster-01, but cannot be checked out to cluster Corp-cluster-02. The images also cannot be checked out to any other clusters that are registered with Prism Central in the future.

Which two configuration settings must the administrator choose when creating the image placement policy that satisfies the stated requirements? (Choose two.)

Options:

A.

Create an image placement policy that identifies cluster Corp-cluster-01 as the target cluster


B.

Set the policy enforcement to Soft.


C.

Set the policy enforcement to Hard.


D.

Create an image placement policy that identifies cluster Corp-cluster-02 as the target cluster.
