Which document can the consultant use to verify all tasks have been closed out?
A. As-Built Guide B. Deployment Questionnaire C. Deployment Guide D. Deployment Checklist
D. Deployment Checklist
Explanation/Reference:
To verify that all in-scope tasks for a new cluster deployment have been completed, the consultant should refer to the:

Question 273:
A customer has a G6 AHV cluster with 4x10GbE NICs on each node and the following configuration:
1.
Networking is set to default
2.
Only two NICs are connected
The customer receives the following critical message:
The NIC is disconnected from the switch, or the switchport is failing.
What should the consultant verify to resolve the issue?
A. The NICs are configured for active-backup. B. The VLANs are configured correctly on the switch or tagged on the cluster. C. The other two 10GbE connections are removed from the default bond. D. The NICs are connected for balance-slb.
A. The NICs are configured for active-backup.
Explanation/Reference:
Given the critical message about the NIC being disconnected or the switchport failing, the consultant should first verify the bonding mode of the NICs, especially since only two out of four 10GbE NICs are connected. In an AHV cluster, the NICs can be configured in different bonding modes such as active-active or active-backup. Ensuring that the NICs are configured for active-backup can provide redundancy by allowing one NIC to take over if the other fails, which seems to be necessary given the critical error indicating a possible disconnection or switchport failure.

Question 274:
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
C. Portfast
Explanation/Reference:
In this scenario, the delay and packet loss during failover when one of the network cables is disconnected can be addressed by enabling "Portfast" on the switch ports connected to the Nutanix nodes. Portfast is a Cisco network switch feature that allows network switches to immediately bring ports into the forwarding state during connectivity changes, bypassing the usual listening and learning states of Spanning Tree Protocol (STP). This significantly reduces the time to reestablish network connectivity, thereby minimizing the packet loss during such failover events. Enabling Portfast is crucial for endpoints like servers where quick recovery from disconnections is necessary.References: Cisco Networking Academy materials on STP and Portfast, Nutanix Bible.
Question 275:
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.
C. The duster data services IP address is a bottleneck, shared with other iSCSI traffic
Question 276:
An administrator is deploying a new application to a Nutanix Enterprise Cloud. The application requires a security to prevent unauthorized access. The application also uses many non-standard ports that are unique to it. Security should not be changed for existing applications.
What should the administrator do to meet these requirement?
A. Use existing categories for the VMs. and create new security policies to use the existing categories. B. Use existing categories for the VMs and modify existing security policies to include the specific port. C. Create new categories for the VMs, and create new security policies that include the new categories. D. Create new categories for the VMs, and modify existing security policies to include the new categories.
C. Create new categories for the VMs, and create new security policies that include the new categories.
Explanation/Reference:
To ensure the new application is securely deployed without affecting existing applications, the administrator should create new categories for the VMs hosting the new application. This approach allows for targeted application of security policies without impacting other applications. After creating these new categories, the administrator should then create new security policies that incorporate these categories and specify the unique, non-standard ports used by the application, ensuring that security is tailored specifically to the new application's needs.References: Nutanix Prism Central Guide, Nutanix Security Configuration Best Practices.
Question 277:
A customer has two mission-critical applications and needs to have them backed up to a remote location. The remote location is connected using a leased line and has an average latency of 7 ms.
Which Nutanix technology will provide the shortest RPO possible?
A. NearSync B. Leap C. Metro Availability D. AsynandDR
A consultant is not able to run the As-Built Tool for a technical reason.
What action should the consultant take to gather information and provide customer documentation?
A. Manually create documentation using As-Built document template. B. Use RVTools for vSphere and Hyper-V deployments. C. Create a support case on behalf of a customer. D. Access portal.nutanix.com, search Software Documentation.
A. Manually create documentation using As-Built document template.
Explanation/Reference:
If the As-Built Tool cannot be run due to technical reasons, the next best action for the consultant is to manually create documentation using an As-Built document template. This approach ensures that documentation is still provided to the customer detailing the setup, configuration, and operational state of their environment, which is crucial for ongoing management and future audits. This method is proactive and ensures customer needs are met despite technical setbacks. References: Nutanix Technical Documentation Guidelines, Best Practices in Nutanix System Documentation.
Question 279:
A customer buys ultimate licensing and wants to use the built-in Nutanix software encryption on their new AHV cluster. The customer needs to create three storage containers and asks the consultant to complete the process as fast as possible.
The optimal sequence for deploying a Nutanix AHV cluster with built-in software encryption involves the following steps:
Create Cluster: Establish the cluster foundation, which sets up the basic network and cluster configurations.
Install License Key: The ultimate licensing must be applied before enabling encryption because the feature depends on this license. Encrypt Cluster: Once the cluster is created and licensed, enable encryption to secure the data at rest. This
step should be done before creating storage containers to ensure that all data written to the containers is encrypted from the outset. Create Storage Containers: Finally, create the storage containers. With encryption already enabled, any data
written to these containers will be automatically encrypted.

Question 280:
An administrator receives a notification that storage in a Nutanix cluster is unavailable. The cluster consists of five nodes and is configured with a Fault-Tolerance level of 1 (FT-1).
Upon investigation, the administrator finds the following:
1.
All AHV hosts are powered on and the CVMs are running
2.
Nodes A, B, and C are connected to one top of rack switch
3.
Nodes D and E are connected to a second top of rack switch
4.
The cluster status command run on Node A shows that CVM services on nodes D and E are down
Which issue is causing the storage outage?
A. The default gateway for the CVMs and AHV hosts is down. B. The switch connecting Nodes D and E is down. C. The genesis process is down on both Nodes D and E. D. Nodes D and E are in maintenance mode.
