Scenarios P4 Flashcards
A vSphere environment is experiencing intermittent short bursts of CPU contention, causing brief
production outages for some of the virtual machines (VMs). To understand the cause of the issue,
the administrator wants to observe near real-time statistics tor all VMs.
Which two vSphere reporting tools could the administrator use? (Choose two.)
A. Advanced Performance Charts
B. esxcli
C. resxtop
D. Overview Performance Charts
E. esxtop
Answer: CE
Explanation:
Advanced performance charts for cpu (ready and usage counters) are only for esxi’s cpu, but we
can only view the same counters individually for every vm’s in their monitoring tab. Only esxtop and
resxtop are displaying the cpu counters for all the vms of a host in a single view.
An administrator is performing maintenance activities and discovers that a Virtual Machine File
System (VMFS) datastore has a lot more used capacity than expected. The datastore contains 10
virtual machines (VMs) and, when the administrator reviews the contents of the associated
datastore, discovers that five virtual machines have a snapshot file (-delta.vmdk files) that has not
been modified in over 12 months. The administrator checks the Snapshot Manager within the
vSphere Client and confirms that there are no snapshots visible.
Which task should the administrator complete on the virtual machines to free up datastore space?
A. Consolidate the snapshots for each VM.
B. Inflate the disk files for each VM.
C. Delete all snapshots for each VM.
D. Storage vMotion each VM to another datastore.
Answer: A
Explanation:
The presence of redundant delta disks can adversely affect the virtual machine performance. You
can combine such disks without violating a data dependency. After consolidation, redundant disks
are removed, which improves the virtual machine performance and saves storage space.
An administrator is attempting to configure Storage I/O Control (SIOC) on five datastores within a
vSphere environment. The administrator is being asked to determine why SIOC configuration
completed successfully on only four of the datastores.
What are two possible reasons why the configuration was not successful? (Choose two.)
A. The datastore contains Raw Device Mappings (RDMs).
B. SAS disks are used for the datastore.
C. The datastore has multiple extents.
D. The datastore is using ISCSI.
E. The administrator is using NFS storage.
Answer: AC
Explanation:
Storage I/O Control is supported on Fibre Channel-connected, iSCSI-connected, and NFS-
connected storage. Raw Device Mapping (RDM) is not supported.
Storage I/O Control does not support datastores with multiple extents.
An administrator has mapped three vSphere zones to three vSphere clusters.
Which two statements are true for this vSphere with Tanzu zonal Supervisor enablement? (Choose
two.)
A. One Supervisor will be created in a specific zone.
B. One Supervisor will be created across all zones.
C. Three Supervisors will be created in Linked Mode.
D. Individual vSphere Namespaces will be placed into a specific zone.
E. Individual vSphere Namespaces will be spread across all zones.
Answer: AD
Explanation:
In a three-zone Supervisor, a namespace resource pool is created on each vSphere cluster that is
mapped to a zone. The namespace spreads across all three vSphere clusters in each zone
An administrator is investigating reports of users experiencing difficulties logging into a VMware
vCenter instance using LDAP accounts.
Which service should the administrator check as part of troubleshooting?
A. vSphere Authentication Proxy Service
B. Lookup Service
C. Identity Management Service
D. VMware Authentication Framework Daemon
C

consists of 75 hosts and is expected to grow up to 100 hosts over the next three years.
Which deployment size should the administrator select?
A. Medium
B. Tiny
C. Large
D. Small
Answer: D
An administrator has been notified that a number of hosts are not compliant with the company
policy for time synchronization.
The relevant portion of the policy states
All physical servers must synchronize time with an external time source that is accurate to the
microsecond.
Which step should the administrator take to ensure compliance with the policy?
A. Ensure that each vCenter Server Appliance is configured to use a Network Time Protocol (NTP)
source.
B. Ensure that each ESXi host is configured to use a Precision Time Protocol (PTP) source.
C. Ensure that each ESXi host is configured to use a Network Time Protocol (NTP) source.
D. Ensure that each vCenter Server Appliance is configured to use a Precision Time Protocol (PTP)
source
B
Following a merger with another company, an administrator is tasked with configuring an identity
source for VMware vCenter so that all vSphere administrators can authenticate using their existing
Active Directory accounts. Each company has user accounts in their own Active Directory forests.
The following additional information has been provided:
The corporate policy states that only Windows-based machine accounts are allowed in Active
Directory.
Which action should the administrator take to configure vCenter Single Sign-On (SSO) to meet this
requirement?
A. Configure SSO to use Active Directory over LDAP as the identity source.
B. Configure SSO to use OpenLDAP as the identity source.
C. Join the vCenter Server Appliance to the LDAP domain.
D. Configure SSO to use Active Directory (Integrated Windows Authentication) as the identity source.
Answer: A
Explanation:
Integrated Windows Authentication is now depreciated (from v7). The Active Directory over LDAP
identity source is preferred over the Active Directory (Integrated Windows Authentication) option.
Which two performance tools can be used to monitor virtual machines outside the guest operating
system? (Choose two.)
A. vCenter Server performance charts
B. Task Manager
C. top
D. esxtop
E. Perfmon
Answer: AD
Explanation:
Perfmon is an inside OS tool that’s why it is wrong
esxtop is used to troubleshoot perf issues.
What is the default shutdown order of virtual machines (VMs) on a host? (Choose the best answer.)
A. Alphabetical based on VM names
B. Highest utilization to lowest utilization
C. Largest VM to smallest VM
D. Reverse of the startup order
Answer: D
Explanation:
The order in which virtual machines are powered off is the reverse of their startup order
An administrator is tasked with applying updates to a vSphere cluster running vSAN using vSphere
Lifecycle Manager. Downtime to the ESXi hosts must be minimal while the work is completed.
The administrator has already completed the following steps and no errors have been returned:
- Downloaded all applicable software and created a new image.
- Attached the new image to the cluster and run a compliance check against the image for the
cluster.
- Ran a remediation pre-check for the cluster.
Which two series of steps should the administrator perform to start the remediation of the cluster
using the new image? (Choose two.)
A. 1. Use the Remediate option in vSphere Lifecycle Manager to remediate all of the ESXi hosts in
the cluster in parallel.
2. Allow vSphere Lifecycle Manager to automatically control maintenance mode on the ESXi hosts.
B. 1. Place each of the ESXi hosts into maintenance mode manually.
2. Use the Stage option in vSphere Lifecycle Manager to stage the required software on all ESXi
hosts one at a time.
C. 1. Leave all ESXi hosts in the cluster operational.
2. Use the Stage All option in vSphere Lifecycle Manager to stage the required software onto all
ESXi hosts one at a time.
D. 1. Leave all ESXi hosts in the cluster operational.
2. Use the Stage All option in vSphere Lifecycle Manager to stage the required software onto all
ESXi hosts in the cluster in parallel.
E. 1. Use the Remediate option in vSphere Lifecycle Manager to remediate all of the ESXi hosts in
the cluster in sequence.
2. Allow vSphere Lifecycle Manager to automatically control maintenance mode on the ESXi hosts
Answer: CE
Explanation:
Generally you would want to patch a vSAN cluster a node at a time (sequentially) so you do not
inadvertently cause a storage outage in the cluster. Also, if you look in the link below, you cannot
remediate a vSAN cluster in parallel mode:
Parallel remediation is deactivated by default, but you can enable it during remediation or in the
vSphere Lifecycle Manager general remediation settings.
You cannot remediate in parallel hosts in a vSAN cluster.

D. VMware NSX
C
An administrator is tasked with configuring remote direct memory access (RDMA) over Converged
Ethernet v2 (RoCE v2).
Which two types of adapters must the administrator configure? (Choose two.)
A. Paravirtual RDMA adapter
B. RDMA network adapter
C. Software iSCSi adapter
D. Fibre Channel over Ethernet (FCoE) adapter
E. Software NVMe over RDMA storage adapter
Answer: BE
Explanation:
ESXi 7 and later supports RoCE v2 technology, which enables RDMA over an Ethernet network.
Hosts use an RDMA network adapter installed on the host and a software NVMe over RDMA
storage adapter.
An administrator has a host profile named Standard-Config. The administrator wants to change the
other host profiles to use only the storage configuration settings that are defined in the Standard-
Config host profile.
What should the administrator do to make this change?
A. Export host customizations and import them to the other host profiles.
B. Copy the storage settings from Standard-Config to all other host profiles.
C. Duplicate the Standard-Config host profile and only modify the storage configuration settings.
D. Export the Standard-Config host profile and attach it to tile other hosts.
B
A vSphere cluster has the following configuration:
- Virtual machines (VMs) are running Production and Test workloads vSphere Distributed Resource
Scheduler (DRS) is enabled
- There are no resource pools in the cluster
Performance monitoring data shows that the Production workload VMs are not receiving their fully
allocated memory when the vSphere cluster is fully utilized.
A combination of which two steps could the administrator perform to ensure that the Production
VMs are always guaranteed the full allocation of memory? (Choose two.)
A. Assign a custom memory share value to the resource pool containing the Production VMs.
B. Assign a memory reservation value to the resource pool containing the Production VMs.
C. Create a parent resource pool for the Production VMs.
D. Create a sibling resource pool for each of the Production and Test VMs.
E. Create a child resource pool for the Test VMs.
Answer: BC
Explanation:
You guarantee resources by setting a reservation on the pool. You cannot set a reservation on a
pool that doesn’t exist
