3V0-22.21N Sample Questions

3V0-22.21N Sample Questions & Answers

Setting up networking and storage, then managing and remediating hosts and clusters, carries the most weight, next to standing up vCenter with SSO, HA and DRS clustering, configuring advanced VM settings, and troubleshooting resource, network and storage problems.

    Troubleshooting and Repairing · Troubleshoot network and storage issues

    A vSphere administrator is troubleshooting a vSAN cluster where a specific VM has become inaccessible. Upon checking the vSAN health, the object health status shows 'Inaccessible'.

    Which of the following scenarios would lead to an object becoming 'Inaccessible' rather than 'Absent'?

    Show answer & explanation

    Correct answer: A

    If more than 50% of an object's components (votes) are missing, the object loses quorum and becomes Inaccessible. 'Absent' is typically used for transient failures (like a host reboot or network partition) where the data is expected to return shortly, but quorum loss results in immediate inaccessibility.

  2. Question 2Intermediate

    Administrative and Operational Tasks · Set up networking and storage

    You are configuring a vSphere Distributed Switch (VDS) to support Link Aggregation Control Protocol (LACP) for increased bandwidth and redundancy. The physical switch ports are configured for dynamic LACP.

    Which Load Balancing algorithm MUST be selected on the LAG (Link Aggregation Group) for LACP to function correctly?

    Show answer & explanation

    Correct answer: A

    When configuring a LAG on a VDS, you cannot use the standard VDS load balancing policies (like Route based on physical NIC load). You must select one of the supported LACP hashing algorithms available within the LAG configuration properties.

  3. Question 3Intermediate

    Installing, Configuring, and Setup · Set up DRS clustering

    True or False: In a vSphere 7.x cluster with DRS enabled, 'Scalable Shares' are disabled by default and must be explicitly enabled to solve the 'resource pool pie paradox' where high-priority pools with few VMs might receive fewer resources than low-priority pools with many VMs.

    Show answer & explanation

    Correct answer: A

    This is True. Scalable Shares are disabled by default in vSphere 7. When enabled, they ensure that resource entitlement is dynamic based on the number of VMs in the pool, preventing the scenario where a High priority pool with 1 VM gets less total resource than a Low priority pool with 100 VMs.

  4. Question 4Intermediate

    Administrative and Operational Tasks · Host and cluster management and remediation

    You are managing a vSphere Lifecycle Manager (vLCM) cluster. You need to ensure that the firmware on the HBA cards across all hosts matches the driver version included in the ESXi image.

    What component must you configure in vLCM to achieve this full-stack compliance?

    Show answer & explanation

    Correct answer: A

    The Hardware Support Manager (HSM) is a plugin provided by the hardware vendor (e.g., Dell OMIVV, HPE OneView) that integrates with vLCM to manage firmware updates and ensure they align with the drivers in the software image.

  5. Question 5Advanced

    Administrative and Operational Tasks · Content libraries

    Case Study:

    Scenario

    GlobalBank Corp has a vSphere 7.x environment spanning two data centers (DC1 and DC2) connected by a 10Gbps link with 5ms latency. They are implementing a Content Library to manage VM templates and ISOs.

    Requirements

    1. The 'Master' library must exist in DC1.
    2. DC2 must have local copies of all templates for fast deployment.
    3. Bandwidth usage for synchronization must be minimized during business hours.
    4. Storage space in DC2 is limited; only frequently used templates should be stored physically, others should be pulled on demand.

    Current Situation

    Currently, administrators manually copy OVF files between sites, which is error-prone. The team wants to automate this using vCenter Content Libraries.

    Question

    Based on the requirements, how should you configure the Content Library in DC2?

    Show answer & explanation

    Correct answer: A

    Creating a Subscribed Library with 'Download content when needed' (On-demand) meets the requirement to save storage space. Only metadata is synced initially. When a template is deployed, the content is downloaded. This satisfies the storage constraint while automating the availability of templates.

  6. Question 6Intermediate

    Troubleshooting and Repairing · Troubleshoot vSphere infrastructure issues

    You are attempting to perform a Storage vMotion of a running virtual machine, but the migration fails with an error indicating 'The virtual machine is configured with a device that prevents the operation'.

    Which of the following device configurations would prevent a live Storage vMotion?

    Show answer & explanation

    Correct answer: D

    A CD-ROM connected to a 'Client Device' (the administrator's local machine) or a local host file path that is not accessible to the destination can prevent vMotion. Disconnecting the CD-ROM or setting it to a shared datastore ISO resolves this.
