An administrator is designing a vSAN cluster and needs to understand the role of the witness component in vSAN objects. Which statement accurately describes the witness component's purpose?

A vSAN administrator needs to configure a storage policy that can tolerate two host failures while minimizing storage overhead. The cluster has 8 hosts. Which configuration should be implemented?

During a vSAN health check, an administrator notices the 'Network latency check' is failing with high latency values between hosts. Which action should be taken first to identify the root cause?

What is the minimum number of hosts required to create a vSAN cluster using RAID-5 erasure coding?

An organization is deploying a two-node vSAN cluster. Which component is mandatory for this configuration to function properly?

A vSAN administrator notices that resynchronization operations are consuming excessive bandwidth during business hours. Which configuration change would help control the impact of resync operations?

In a vSAN environment, what is the primary function of the disk group's cache tier when using all-flash configurations?

A company is deploying vSAN in a stretched cluster configuration across two sites. An administrator needs to configure the failure domain settings. What is the minimum number of hosts required at the preferred site to maintain operations if the secondary site fails?

An administrator observes that vSAN performance has degraded. Upon investigation, they find that many disk groups show high congestion values. What is the most likely cause?

Which vSAN feature automatically redistributes data across the cluster when capacity usage becomes unbalanced between hosts?

A vSAN cluster is experiencing performance issues. The administrator notices that several virtual machines have object components in a 'degraded' state. What is the most appropriate immediate action?

An administrator needs to enable vSAN encryption on an existing cluster. Which prerequisite must be met before encryption can be configured?

In a vSAN environment, what does the 'Site disaster tolerance' storage policy setting control in a stretched cluster?

A vSAN cluster has deduplication and compression enabled. An administrator notices that the space savings ratio is lower than expected. Which workload characteristic would result in minimal space savings?

An administrator is planning to place a vSAN host into maintenance mode. The cluster is running at 75% capacity utilization. Which maintenance mode option ensures that all data remains fully compliant with storage policies but requires the most free space?

A vSAN administrator needs to understand component placement logic. When vSAN places components of an object across the cluster, which factor does it primarily consider to optimize placement?

An organization is designing a vSAN cluster for mixed workloads including latency-sensitive applications and batch processing jobs. Which approach provides the best isolation for latency-sensitive workloads?

A vSAN health check shows the alarm 'vSAN cluster partition detected'. What is the most likely cause of this issue?

What is the function of the vSAN Cluster Service (CMMDS) in the vSAN architecture?
