Question 141:
Administrator successfully installs VMware ESXi onto the first host of a new vSphere duster but makes no additional configuration changes. When attempting to log into the vSphere Host Client using the Fully Qualified Domain Name (FQDN) of the host, the administrator receives the following error message:
"server Not Found –we can't connect to the server at esxit101.corp.local." Host FQDN: esxi 101. Corp. local Management VLAN ID: 10 DHCP: No Management IP Address: 172.16.10.101/24 Management IP Gateway: 172.16.10.1 Corporate DNS Servers: 172.16.10.5, 172.16.10.6 DNS Domain: corp.local
Which three high level tasks should the administrator complete, at a minimum, in order to successfully log into the
the vSphsrs Host Client using the FQDN for the exxi101 and complete the configuration (Choose three.)
A. Ensure a DNS A Record Is created for the VMware ESXI host on the corporate DNS servers, B. Update the VMware ESXI Management Network DNS configuration to use the corporate DNS servers for name, resolution, C. Update the VMware ESXI Management Network IPv4 configuration to use a static a IPv4 address. D. Configure at least two network adapters for the VMware ESXI Management Network. E. Set the value of the VMware ESXI Management Network VLAN ID to 10. F. Disable IPv6 for the VMware ESXI Management Network.
A. Ensure a DNS A Record Is created for the VMware ESXI host on the corporate DNS servers, B. Update the VMware ESXI Management Network DNS configuration to use the corporate DNS servers for name, resolution,
Explanation/Reference:
To successfully log into the vSphere Host Client using the FQDN for the ESXi host, the administrator needs to ensure a DNS A Record is created for the VMware ESXi host on the corporate DNS servers, which maps its FQDN to its IP address; and update the VMware ESXi Management Network DNS configuration to use the corporate DNS servers for name resolution, which allows resolving its FQDN.

Question 142:
Which tool is used to monitor the vCenter Server Appliance resources? (Choose the best answer.)
An administrator creates a new corporate virtual machine (VM) template every month to include all of the latest patches. The administrator needs to ensure that the new VM template is synchronized from the primary data center site (London) to two secondary data center sites (Tokyo and New York). The administrator is aware that datastore space is limited within the secondary data center sites. The administrator needs to ensure that the VM template is available in the secondary sites the first time a new virtual machine is requested.
Which four steps should the administrator take to meet these requirements? (Choose four.)
A. Create a new published content library at the primary site. B. Add the virtual machine template to the subscribed content library. C. Create a new published content library in each secondary site. D. Create a new subscribed content library in each secondary site. E. Configure the subscribed content library to download content when needed. F. Configure each subscribed content library to download content immediately. G. Add the virtual machine template to the published content library.
A. Create a new published content library at the primary site. D. Create a new subscribed content library in each secondary site. E. Configure the subscribed content library to download content when needed. G. Add the virtual machine template to the published content library.
Explanation/Reference:
To meet the requirements of synchronizing and protecting images and templates with limited datastore space, the administrator needs to create a new published content library at the primary site, which makes it available for subscription by other vCenter Server instances; create a new subscribed content library in each secondary site, which allows accessing content from a published content library; configure the subscribed content library to download content when needed, which saves datastore space by only downloading content on demand; and add the virtual machine template to the published content library, which makes it available for other hosts to use.

Question 144:
An administrator successfully installs VMware ESXi onto the first host of a new vSphere cluster but makes no additional configuration changes. When attempting to log into the vSphere Host Client using the Fully Qualified Domain Name
(FQDN) of the host, the administrator receives the following error message:
"Server Not Found - We can't connect to the server at esxi101.corp.local?
The following information has been provided to complete the configuration:
Host FQDN esxi101.corp.local
Management VLAN ID: 10
DHCP: No
Management IP Address: 172.16 10.101 / 24
Management IP Gateway: 172.16.10.1
Corporate DNS Servers: 172.16 10.5, 172.16.10.6
ONS Domain: corp.local
In addition, all host configurations must also meet the following requirements:
The management network must use only IPv4 network protocols.
The management network must be fault tolerant
Which three high level tasks should the administrator complete, at a minimum, in order to successfully log into the vSphere Host Client using the FQDN for esxi101 and complete the configuration? (Choose three.)
A. Ensure a DNS A Record is created for the VMware ESXi host on the corporate DNS servers. B. Update the VMware ESXi Management Network DNS configuration to use the corporate DNS servers for names resolution C. Update the VMware ESXi Management Network IPv4 configuration to use a static a IPv4 address D. Configure at least two network adapters for the VMware ESXi Management Network E. Set the value of the VMware ESXi Management Network VLAN ID to 10 F. Disable IPv6 for the VMware ESXi Management Network

Question 145:
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 Horizon B. VMware vSAN C. VMware vSphere D. VMware
C. VMware vSphere
Explanation/Reference:
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
Question 146:
Which step is required when adding an existing hard disk that is configured as a boot disk during virtual machine creation? (Choose the best answer.)
A. Enable Secure Boot. B. Select `RDM Disk' from the `Add New Device' drop-down menu. C. Remove the existing disk before adding the boot disk. D. Set the boot delay to at least 5,000 milliseconds.
C. Remove the existing disk before adding the boot disk.
Question 147:
An administrator has configured Storage I/O Control (SIOC) on a Virtual Machine File System (VMFS) datastore.
The datastore supports 30,000 IOPS
Storage I/O Control has been set to manual
Storage I/O Control is triggered when latency hits 30 ms
The datastore contains 3 virtual machines (VMs)
A gold tier VM
A silver tier VM
A bronze tier VM
Assuming the datastore latency does not exceed 29ms, what is the maximum number of IOPS the bronze tier VM is entitled to?
A. 30,000 B. 20,000 C. 10.000 D. 5,000
A. 30,000
Explanation/Reference:
The bronze tier VM is entitled to 30,000 IOPS, which is the maximum number of IOPS that the datastore supports. Storage I/O Control (SIOC) does not limit the IOPS of any VM unless the datastore latency exceeds the threshold, which is 30 ms in this case. Therefore, as long as the datastore latency is below 29 ms, the bronze tier VM can use up to 30,000 IOPS.

Question 148:
Which feature can be used to specify data services for virtual disks, such as caching or replication? (Choose the best answer.)
A. Host profiles B. Virtual machine storage policies C. VM Customization Specification D. Storage Distributed Resource Scheduler (DRS)
An administrator wants to be able to send vCenter Server log files to a remote syslog server and analyze logs using vRealize Log Insight. Which step must the administrator take to meet this requirement? (Choose the best answer.)
A. Configure the vCenter Server logging options using the vSphere Client. B. Specify the remote syslog server name at deployment using the vCenter Server GUI Installer. C. Specify the vRealize Log Insight system name using the vSphere Client. D. Configure log file forwarding using the vCenter Server Management Interface.
D. Configure log file forwarding using the vCenter Server Management Interface.
Question 150:
An administrator manually configures a reference ESXi host that meets company security standards for vSphere environments. The administrator now needs to apply all of the security standards to every identically configured host across multiple vSphere clusters within a single VMware vCenter instance.
Which four steps would the administrator complete to meet this requirement? (Choose four.)
A. Extract the host profile from the reference host B. Export the host profile from vCenter. C. Import host customization on the reference host. D. Attach the host profile to each cluster that requires the secure configuration. E. Check the compliance of each host against the host profile. F. Reset host customization on the reference host. G. Remediate all non-compliant hosts.
A. Extract the host profile from the reference host D. Attach the host profile to each cluster that requires the secure configuration. E. Check the compliance of each host against the host profile. G. Remediate all non-compliant hosts.
Explanation/Reference:
To apply the security standards from a reference host to other hosts across multiple clusters, the administrator needs to extract a host profile from the reference host, which captures its configuration settings; attach the host profile to each cluster that requires the same configuration; check the compliance of each host against the host profile, which compares their settings; and remediate all non-compliant hosts, which applies the configuration settings from the host profile.
