NEW QUESTION # 36
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 Precision Time Protocol (PTP) source.
- B. Ensure that each ESXi host is configured to use a Network Time Protocol (NTP) source.
- C. Ensure that each ESXi host is configured to use a Precision Time Protocol (PTP) source.
- D. Ensure that each vCenter Server Appliance is configured to use a Network Time Protocol (NTP) source.
Answer: C
Explanation:
To comply with the policy of synchronizing time with an external source that is accurate to the microsecond, the administrator needs to ensure that each ESXi host is configured to use a PTP source, which provides higher accuracy than NTP.

NEW QUESTION # 38
An administrator needs to consolidate a number of physical servers by migrating the workloads to a software-defined data center solution.
Which VMware solution should the administrator recommend?
- A. VMware vSphere
- B. VMware
- C. VMware vSAN
- D. VMware Horizon
Answer: A
Explanation:
Explanation
Option C is correct because VMware vSphere is the solution that provides a software-defined data center platform that can consolidate physical servers by migrating the workloads to virtual machines. Option A is incorrect because VMware Horizon is a solution for virtual desktop infrastructure (VDI) and application delivery. Option B is incorrect because VMware vSAN is a solution for software-defined storage that is integrated with vSphere. Option D is incorrect because VMware NSX is a solution for software-defined networking that is integrated with vSphere. References: https://www.vmware.com/products/vsphere.html
NEW QUESTION # 39
Refer to the exhibit.
After updating a predefined alarm on VMware vCenter, an administrator enables email notifications as shown in the attached alarm; however, notifications are NOT being sent.
Where must the mail server settings be configured by the administrator to resolve this issue?
- A. in the vCenter Management Interface
- B. In the ESXi host system config
- C. In the vCenter settings in the vSphere Client
- D. In the alarm rule definitions
Answer: C
Explanation:
Explanation
Option C is correct because it allows the administrator to configure the mail server settings in the vCenter settings in the vSphere Client, which are required for sending email notifications for alarms. Option A is incorrect because it configures the mail server settings on an ESXi host system, which are not used for sending email notifications for alarms. Option B is incorrect because it configures the alarm rule definitions, which are already enabled in the exhibit. Option D is incorrect because it configures the vCenter Management Interface, which is not used for sending email notifications for alarms. References:

- A. On the vCenter Management Interface
- B. On the vCenter Server Appliance
- C. In the vSphere Client when viewing the vCenter virtual machine
- D. On the ESXi host using the Direct Console User Interface
Answer: B
Explanation:
Explanation
The administrator can find log files containing information related to user login activities on the vCenter Server Appliance, which is a preconfigured Linux-based virtual machine that runs all vCenter Server services.
The log files are located in /var/log/vmware/vmware-vpx/vpxd.log and
/var/log/vmware/sso/ssoAdminServer.log directories. References:

NEW QUESTION # 46
An administrator is tasked with looking into the disaster recovery options for protecting a database server using VMware vSphere Replication.
The following requirements must be met:
* The virtual machine must remain online during the protection.
* The virtual machine's snapshots must be used as part of the replication process.
Which step must the administrator complete to accomplish this task?
- A. Configure network traffic isolation for vSphere Replication.
- B. Perform a full initial synchronization of the source virtual machine to the target location.
- C. Configure the virtual machine storage policy.
- D. Enable guest OS VSS quiescing for this virtual machine.
Answer: D
Explanation:
Explanation
Option B is correct because it indicates that enabling guest OS VSS quiescing for this virtual machine is required for protecting a database server using VMware vSphere Replication, as this will ensure that application-consistent snapshots are used as part of the replication process. Option A is incorrect because configuring the virtual machine storage policy does not affect how vSphere Replication protects a database server. Option C is incorrect because performing a full initial synchronization of the source virtual machine to the target location does not affect how vSphere Replication protects a database server after synchronization.
Option D is incorrect because configuring network traffic isolation for vSphere Replication does not affect how vSphere Replication protects a database server. References:

NEW QUESTION # 47
An administrator is working with VMware Support and Is asked to provide log bundles for the ESXI hosts in an environment.
h three options Joes the administrator have? (Choose three.)
- A. Generate a separate log bundle for each ESXI host using the vSphere Client.
- B. Generate a combined log bundle for all ESXI hosts using the vSphere Client.
- C. Generate a combined log bundle for all ESXi hosts using the vSphere Host Client.
- D. Generate a combined log bundle for all ESXI hosts using the vCenter Management Interface.
- E. Generate a separate log bundle for each ESXI host using the vSphere Host Client.
- F. Generate a separate log bundle for each ESXI host using the vCenter Management Interface.
Answer: A,B,E
Explanation:
Option B, C and D are correct because they are valid methods to generate log bundles for individual or multiple ESXi hosts using different interfaces. Option A and E are incorrect because they are not possible options to generate log bundles for all ESXi hosts using the vCenter Management Interface. Option F is incorrect because it is not possible to generate a combined log bundle for all ESXi hosts using the vSphere Host Client.

NEW QUESTION # 52
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 has multiple extents.
- B. SAS disks are used for the datastore.
- C. The datastore contains Raw Device Mappings (RDMs).
- D. The datastore is using ISCSI.
- E. The administrator is using NFS storage.
Answer: A,C
Explanation:
Explanation
SIOC configuration may fail if the datastore contains RDMs or has multiple extents, as these are not supported by SIOC.

NEW QUESTION # 53
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. Create a child resource pool for the Test 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. Assign a memory reservation value to the resource pool containing the Production VMs.
Answer: B,E
Explanation:
Explanation
Option B and E are correct because they allow the administrator to create resource pools for the Production and Test VMs and assign memory reservation values to the Production resource pool, which guarantees that the Production VMs are always allocated their full memory. Option A is incorrect because assigning a custom memory share value to the Production resource pool does not guarantee that the Production VMs are always allocated their full memory, but only gives them higher priority when there is contention. Option C is incorrect because creating a parent resource pool for the Production VMs does not change anything unless there are child resource pools under it. Option D is incorrect because creating a sibling resource pool for each of the Production and Test VMs does not change anything unless there are different resource settings for each pool.
