• Question 124:

  A consultant needs to verify the make and model of the systems that will be imaged with Foundation. The consultant does not have the Bill of Materials (BOM) available to review. When should the consultant verify the make and model to prepare for the cluster deployment?

  A. During the Foundation Process

  B. While conducting the Tech Review Call

  C. Upon arriving on-site

  D. When reviewing the Statement of Work (SOW)

  Correct Answer: A

• Question 125:

  An administrator is deploying an application using Nutanix Volumes. After configuring the volume group and connecting the guest's iSCSI initiator to the volume group, they begin performance testing.

  The administrator learns that performance on the virtual disk attached to the iSCSI initiator is far less than that of a virtual disk connected directly to the VM.

  Which situation is causing this condition?

  A. The VM's iSCSI traffic is being routed to the data services IP subnet

  B. The performance test is generating small block random 10.

  C. The duster data services IP address is a bottleneck, shared with other iSCSI traffic

  D. Data Locality ensures that VM attached disks are always faster than iSCSI volumes.

  Correct Answer: C

• Question 126:

  An administrator is deploying a three-tier application on a Nutanix Enterprise Cloud consisting of web, application, and database VMs. Traffic between theservers must be limited to specific services/ports. There is an application layer firewall VM deployed on one host in the cluster.

  In which way should the administrator meet this requirement?

  A. Create a network for each type of VM, and use policy-based routing to control the traffic flow

  B. Configure a security policy and service chain redirecting the server traffic through the firewall

  C. Separate the web. application and database VMs on to dedicated VLANs

  D. Categorize the VMs in Prism Central and utilize Flow to set a security policy

  Correct Answer: D

• Question 127:

  During a technical call with a customer, it is identified that this installation will be software only on Dell servers. The out-of-band management interfaces will not be given IP addresses until the consultant is onsite. Which Foundation method should be used for this type of installation?

  A. Bare metal using iDRAC MAC addresses.

  B. Bare metal using LAN MAC addresses.

  C. Bare metal using block serial numbers.

  D. Bare metal using node serial numbers.

  Correct Answer: A

• Question 128:

  After installation, network ports are properly configured with the default active-backup bonding.

  One 10GbE port goes to switch 1. Another 10GbE port goes to switch 2. A consultant tests failover by manually pulling one of the cables and notices it is taking too much time to failover, which is causing excessive packet loss.

  What should the consultant enable to resolve this issue?

  A. LACP on switch

  B. PAgP

  C. Portfast

  D. Jumbo frames

  Correct Answer: C

• Question 129:

  Which Data Protection Method should be used?

  A. Async

  B. Metro Availability

  C. Near Sync

  D. Cloud Connect

  Correct Answer: C
