Absolutely! I will create tailored scenarios for each exam objective, along with three potential solutions, as described. These scenarios will help test your understanding and allow us to focus on areas that need improvement. Here’s how we’ll structure it:

  • Scenario: A detailed, practical problem.
  • Solutions: Three possible approaches (one fully correct, one partially correct, and one incorrect).
  • Explanation: Detailed feedback based on your answer.

Objective 1: Deploy Nutanix Files

Scenario 1:

You are tasked with deploying Nutanix Files for a company that requires both SMB and NFS file-sharing protocols. The client environment includes Windows and Linux clients, and they need secure access to the shared storage with minimal administrative effort. DNS, NTP, and Active Directory are set up.

Solutions:

  1. Solution A (Fully Correct):
    You configure Nutanix Files with both SMB and NFS shares, securing them with Active Directory integration for Windows clients and NFS Kerberos for Linux. You onboard the file shares into Data Lens for monitoring. You block certain file types and configure permission rules using the Files console.

  2. Solution B (Partially Correct):
    You configure Nutanix Files with SMB and NFS shares. You ensure SMB is secured with AD but don’t configure NFS security, assuming Linux users can rely on local system permissions. Data Lens is not set up yet, but you plan to add it later.

  3. Solution C (Incorrect):
    You configure Nutanix Files but only create SMB shares for the Windows clients and rely on basic file permissions for Linux. You don’t secure NFS with Kerberos, and the deployment skips Data Lens onboarding and Active Directory integration.

Objective 2: Deploy Nutanix Objects

Scenario 2:

You need to deploy Nutanix Objects in an environment that requires multi-region replication and API-based access for developers. The storage should be accessible using S3 endpoints, and the security team wants to enforce WORM (Write-Once-Read-Many) policies for legal retention compliance.

Solutions:

  1. Solution A (Fully Correct):
    You deploy Nutanix Objects with S3 endpoints for API access. Multi-region replication is configured to ensure data availability, and you enforce WORM policies on selected buckets to comply with legal retention. You onboard the object store to Data Lens for advanced monitoring and analytics.

  2. Solution B (Partially Correct):
    You deploy Nutanix Objects with S3 endpoints but do not configure multi-region replication immediately. You enable WORM policies for all buckets but skip onboarding to Data Lens, planning to add monitoring later.

  3. Solution C (Incorrect):
    You deploy Nutanix Objects without configuring replication or WORM policies, relying only on standard bucket access permissions. No Data Lens onboarding is done, and API access is restricted to internal use only.

Objective 3: Upgrade and Scale Nutanix Files and Objects

Scenario 3:

Your organization is running Nutanix Files and Objects on AOS 6.0, and they need to upgrade to AOS 6.5. The team also expects a high increase in storage demands in the next six months, so scaling is a priority. They rely on distributed SMB shares and S3 for their object storage.

Solutions:

  1. Solution A (Fully Correct):
    You first upgrade AOS to 6.5, ensuring all components, including Files and Objects, are compatible. After the upgrade, you scale the Files cluster by adding more FSVMs and enable scaling for Nutanix Objects by expanding the object store and enabling auto-scaling for S3 endpoints.

  2. Solution B (Partially Correct):
    You upgrade AOS and Nutanix Files but postpone the scaling of the Files and Objects cluster. You add additional capacity to Nutanix Objects but don't configure FSVM scaling, planning to monitor load before scaling.

  3. Solution C (Incorrect):
    You scale the Nutanix Files cluster first, then upgrade AOS to 6.5. Nutanix Objects are left unchanged, with no scaling or upgrades performed. The distributed SMB shares are not considered during the process.

Objective 4: Configure Advanced Nutanix Volumes

Scenario 4:

A client wants to use Nutanix Volumes to present storage to a set of physical servers running a critical SQL Server workload. They require iSCSI connectivity with high availability and need to ensure that both performance and security are optimized. The storage should be presented in a way that allows for future scaling without requiring reconfiguration.

Solutions:

  1. Solution A (Fully Correct):
    You configure Nutanix Volumes using iSCSI with CHAP authentication for secure connections. You assign a cluster-wide iSCSI data services IP to balance storage requests and ensure scalability. The configuration allows for future growth without client reconfiguration.

  2. Solution B (Partially Correct):
    You configure Nutanix Volumes with iSCSI but skip CHAP authentication for simplicity. You use individual FSVM IPs for iSCSI connectivity but configure the storage to scale.

  3. Solution C (Incorrect):
    You configure Nutanix Volumes without using CHAP or a cluster-wide iSCSI data services IP. You rely on basic iSCSI connectivity with static IPs for each server and no plans for future scalability.

Objective 5: Monitor and Troubleshoot Nutanix Unified Storage

Scenario 5:

Your team has noticed high latency when accessing certain Nutanix Volumes, affecting performance on a set of physical servers. The storage is provided through iSCSI, and no major changes have been made recently. You need to identify and resolve the issue while ensuring minimal disruption to production workloads.

Solutions:

  1. Solution A (Fully Correct):
    You check the iSCSI data services IP for any network congestion and verify the load-balancing configuration. You then inspect client CHAP authentication and network performance to identify potential bottlenecks. After diagnosing the issue, you adjust the load distribution and monitor the performance in Prism Central.

  2. Solution B (Partially Correct):
    You check the iSCSI connection on each physical server but focus only on the server-side performance metrics. You overlook potential network congestion on the cluster-wide data services IP and rely on basic troubleshooting tools.

  3. Solution C (Incorrect):
    You assume the issue is with the physical servers and restart the iSCSI connection on each one. No checks are made on the Nutanix side, and you ignore potential network bottlenecks in the cluster.

Objective 6: Use File Analytics for Data Security

Scenario 6:

The security team suspects that some unusual file access patterns could indicate a ransomware attack on a Nutanix Files server. They need to use File Analytics to detect any abnormal behavior and prevent further damage.

Solutions:

  1. Solution A (Fully Correct):
    You enable anomaly detection in File Analytics and review the audit trails to identify suspicious access patterns. You configure ransomware protection policies to automatically detect and block any further suspicious activity. A custom report is created for the security team.

  2. Solution B (Partially Correct):
    You enable anomaly detection and audit trails but do not configure automated ransomware protection. You rely on manual monitoring to detect further activity.

  3. Solution C (Incorrect):
    You only check the file server logs manually and disable anomaly detection in File Analytics, assuming that the built-in antivirus will catch any ransomware.

Objective 7: Troubleshoot Nutanix Objects

Scenario 7:

You’ve deployed Nutanix Objects for storing critical logs, but users report that the object store is unreachable. Upon checking, you find that a recent network configuration change may have caused this issue. Your task is to troubleshoot and restore access.

Solutions:

  1. Solution A (Fully Correct):
    You verify that the object store endpoints are correctly configured and accessible through their S3 API. You check the network configuration and ensure that the proper firewall rules are in place for the required ports. After resolving the misconfiguration, you test connectivity and confirm access.

  2. Solution B (Partially Correct):
    You check the firewall settings and endpoint configuration but don’t test the S3 API directly. You assume the issue is related to network changes and revert the last configuration update without further testing.

  3. Solution C (Incorrect):
    You restart the Objects cluster, assuming that the problem is due to an internal service failure. No network or endpoint checks are done, and the firewall configuration is left unchanged.

Objective 8: Troubleshoot a Failed Upgrade

Scenario 8:

During an upgrade of Nutanix Files, you encounter a pre-upgrade check failure indicating that the Active Directory validation step didn’t pass. The upgrade cannot proceed, and production workloads cannot be affected by downtime. Your goal is to resolve the issue and continue the upgrade.

Solutions:

  1. Solution A (Fully Correct):
    You check the Active Directory service accounts and verify the AD integration with Nutanix Files. You revalidate the DNS records and ensure that all AD-related services are reachable. After fixing the AD validation error, you proceed with the upgrade.

  2. Solution B (Partially Correct):
    You skip the AD validation step and proceed with the upgrade after checking that all other pre-upgrade checks passed. You assume the AD issue won’t affect the upgrade.

  3. Solution C (Incorrect):
    You restart the Nutanix Files cluster and attempt the upgrade again without addressing the AD validation error. The upgrade fails again due to the same validation issue.
