   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?

   • AEnsure that each vCenter Server Appliance is configured to use a Network Time Protocol (NTP) source.
   • BEnsure that each ESXi host is configured to use a Precision Time Protocol (PTP) source.
   • CEnsure that each ESXi host is configured to use a Network Time Protocol (NTP) source.
   • DEnsure that each vCenter Server Appliance is configured to use a Precision Time Protocol (PTP) source.

   Show answer

   Answer: B

   Explanation

   B: All physical servers must synchronize time with an external time source that is accurate to the microsecond. NTP is milliseconds.

   An administrator is creating a content library to manage VM templates and ISO images. The administrator wants to password-protect the images and templates and share them with a remote site. Which two tasks must the administration perform when creating the content library? (Choose two.)

   • APublish the local content library.
   • BEnable the security policy.
   • CCreate a subscribed content library.
   • DSelect an NFS datastore.
   • EEnable authentication.

   Show answer

   Answer: AE

   Explanation

   AE is the answer. You enable authentication to password protect a content library. The security policy is to protect and enforce strict validation while importing an synchronizing OVF library items. https://docs.vmware.com/en/VMware-vSphere/8.0/vsphere-vm-administration/GUID-A58AF4FD-6CBE-4210-9E67-27EFBDCC1EF2.html

   An administrator is responsible for the management of a VMware vCenter instance that is currently experiencing performance issues. The administrator quickly identifies that the CPU and memory utilization of vCenter is consistently over 80%. Upon further analysis, it seems that the vpxd process is contributing significantly to the performance issue. A combination of which four steps should the administrator take to resolve the performance issues and ensure that a similar issue can be rectified without requiring downtime to vCenter moving forward? (Choose four.)

   • AGracefully shut down vCenter using the vSphere Client.
   • BEnable CPU Hot Add on the vCenter virtual machine.
   • CPower on the vCenter Server Appliance using the vSphere Host Client.
   • DEnable CPU and Memory Hot Add on the vCenter virtual machine.
   • EAdd additional CPU and memory to the vCenter Server Appliance.
   • FPower on the vCenter Server Appliance using the vSphere Client.
   • GEnable Memory Not Add on the vCenter virtual machine.

   Show answer

   Answer: ACDE

   Explanation

   ACDE: You cannot enable hot add while a VM is running, so you must shut it down first. B is wrong, you enable CPU & memory hot add, not just CPU. You add additional resources while it is powered off to increase performance. Lastly you must power it back on with the host client. You cannot power on vCenter with the vSphere client when vCenter is not running. ;)

   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.)

   • AEnsure a DNS A Record is created for the VMware ESXi host on the corporate DNS servers.
   • BUpdate the VMware ESXi Management Network DNS configuration to use the corporate DNS servers for names resolution.
   • CUpdate the VMware ESXi Management Network IPv4 configuration to use a static a IPv4 address.
   • DConfigure at least two network adapters for the VMware ESXi Management Network.
   • ESet the value of the VMware ESXi Management Network VLAN ID to 10.
   • FDisable IPv6 for the VMware ESXi Management Network.

   Show answer

   Answer: ACE

   Explanation

   The answer is correct based on what is the minimum requirement to log into the host client using the FQDN. B is not required just to log into the host client, you could set that later.

   An administrator is deploying a new all flash vSAN cluster based on the vSAN Original Storage Architecture (OSA). What is the minimum supported network throughput in Gb/s for each host?

   • A50
   • B10
   • C25
   • D1

   Show answer

   Answer: B

   Explanation

   Ans: B vSAN Express Storage Architecture (ESA) are only supported with 25Gbps and higher connection speeds. ESA ReadyNodes configured for vSAN ESA will be configured with 25/50/100Gbps NICs. vSAN OSA all-flash configurations are only supported with a 10Gb or higher connections. One reason for this is that the improved performance with an all-flash configuration may consume more network bandwidth between the hosts to gain higher throughput. https://core.vmware.com/resource/vmware-vsan-design-guide#sec6815-sub3

   An administrator enables Secure Boot on an ESXi host. On booting the ESXi host, the following error message appears: Fatal error: 39 (Secure Boot Failed) What is the cause of this issue?

   • AThe kernel hos been tampered with.
   • BThe Trusted Platform Module chip has failed.
   • CThe administrator attempted to boot with a bootloader that is unsigned or has been tampered with.
   • DA package (VIB or driver) has been tampered with.

   Show answer

   Answer: A

   Explanation

   A Troubleshooting UEFI Secure Boot If secure boot does not succeed at any level of the boot sequence, an error results. The error message depends on the hardware vendor and on the level at which verification did not succeed. If you attempt to boot with a bootloader that is unsigned or has been tampered with, an error during the boot sequence results. The exact message depends on the hardware vendor. It might look like the following error, but might look different. UEFI0073: Unable to boot PXE Device...because of the Secure Boot policy If the kernel has been tampered with, an error like the following results. Fatal error: 39 (Secure Boot Failed) If a package (VIB or driver) has been tampered with, a purple screen with the following message appears. UEFI Secure Boot failed: Failed to verify signatures of the following vibs (XX)
