How to approach hard difficulty questions

These are the questions most candidates get wrong. They require connecting multiple concepts, reading tricky output, or knowing edge-case behaviour that isn't on most study cards. Practising them trains you to operate under uncertainty — a necessary skill on the real exam.

Quick answer

Hard Difficulty Questions questions test whether you can apply the concept in context, not just recognise a definition.

How the topic appears in realistic exam-style scenarios.

Which detail in the question changes the correct answer.

How to eliminate plausible but wrong options.

How to connect the question back to the wider exam objective.

Refer to the exhibit. The performance data shows MEMCTL at 5% and SWPOUT at 2%. What does this indicate about the host?

Exhibit

Refer to the exhibit.
```
esxtop -b -d 30 -n 2 > /tmp/perf.csv

An administrator is troubleshooting a vLCM cluster that has multiple ESXi hosts with non-compliant status. The cluster uses a single image with an HSM for firmware. Which TWO actions should the administrator take to identify the root cause of non-compliance? (Choose two.)

Question 6hardmulti select

Which THREE components are required to implement vSphere with Tanzu (Workload Management)? (Choose three.)

Question 7hardmultiple choice
Full question →

A company has a vSphere environment with 20 ESXi hosts and 500 VMs. The security team mandates that all administrative access to vCenter Server must be through a single, highly restricted account with multi-factor authentication (MFA). The account must be used for both the vSphere Client and API integrations. Which step should the administrator take?

Question 8hardmulti select
Full question →

Which THREE factors should be considered when sizing a host cluster for a VDI environment with 1000 desktops? (Choose three.)

Question 9hardmultiple choice
Full question →

A company has a cluster with DRS set to Fully Automated. A VM named VM1 has a reservation of 4 GHz and a limit of 8 GHz on a host with 10 GHz available. The VM is running a batch job that requires as much CPU as possible. The administrator notices that the VM's CPU usage never exceeds 4 GHz. What is the most likely reason?

Question 10hardmultiple choice
Full question →

A company runs a large vSphere environment with multiple clusters using vSAN. The performance team observes that some VMs are experiencing high latency on reads. The vSAN cluster is configured with 5 hosts, each having one cache tier (NVMe) and one capacity tier (SATA SSD). The VMs are all-flash storage policies. What should the administrator check first?

Question 11hardmultiple choice

An administrator is using vLCM to manage a cluster with 4 ESXi hosts. After a remediation, two hosts show a compliance status of 'Non-Compliant' with the message 'Firmware is not compatible with the selected image'. What is the most likely cause?

Question 12hardmultiple choice
Full question →

An administrator has a vLCM-managed cluster with a desired image that includes a custom VIB from a third party. After remediation, one host shows 'Compliant' but the custom VIB is missing. What is the most likely cause?

Question 13hardmulti select
Full question →

An administrator is troubleshooting a vLCM cluster where remediation fails with 'Host cannot be updated due to missing VIB'. The desired image includes the VIB. Which THREE actions should the administrator take?

Question 14hardmultiple choice
Full question →

A security audit reveals that an ESXi host has been compromised due to an attacker gaining root access via the DCUI. The host is configured with a default DCUI password. Which security best practice should have been implemented to prevent this?

Question 15hardmultiple choice
Full question →

An administrator is troubleshooting a vLCM cluster where a host fails to remediate with the error: 'Host does not meet the requirements of the selected image'. The host is running ESXi 7.0 U3 and the desired image is ESXi 8.0 U1. What should the administrator check first?

Question 16hardmultiple choice
Full question →

A vSphere environment uses Active Directory for authentication. The administrator notices that users from a specific AD group cannot log in to the vCenter Server, although other AD users can. The group is added to vCenter Server with the correct permissions. What is the most likely cause?

Question 17hardmultiple choice
Full question →

An administrator is designing a new vSphere cluster for a mission-critical application that requires extremely low network latency between VMs within the same cluster. The cluster will use vSphere vMotion for maintenance. Which network configuration best meets these requirements?

Which TWO actions are required to enable encrypted vSphere vMotion for all virtual machines in a cluster?

Question 19hardmulti select
Full question →

Which THREE actions can be performed on a VMFS datastore without unmounting it or putting the ESXi host into maintenance mode?

Question 20hardmultiple choice
