An administrator is building a large virtual machine that will require as many vCPUs as the host cansupport. An ESXi 6.x host has these specifications: - Six 32-core Intel Xeon Processors - 256 GB of Memory - 512 GB Local disk space using VMFS5 What is the maximum number of virtual CPUs that the virtual machine can be allocated?
- A.
64
- B.
192
- C.
128
- D.
256
Correct Answer
C. 128Explanation
The maximum number of virtual CPUs that the virtual machine can be allocated is 128. This is because the host has six 32-core processors, which means a total of 192 cores. However, ESXi reserves some cores for system use, so not all 192 cores can be allocated to virtual machines. Typically, ESXi reserves 1 core per socket, so in this case, 6 cores would be reserved. Therefore, the maximum number of virtual CPUs that can be allocated is 192 - 6 = 186. However, ESXi also has a limit of 128 virtual CPUs per virtual machine, so the maximum number of virtual CPUs that can be allocated is 128.Rate this question:

Strict Lockdown Mode has been enabled on an ESXi host.Which action should an administrator perform to allow ESXi Shell or SSH access for users withadministrator privileges?
- A.
Grant the users the administrator role and enable the service.
- B.
Add the users to Exception Users and enable the service.
- C.
No action can be taken, Strict Lockdown Mode prevents direct access.
- D.
Add the users to vsphere.local and enable the service.
Correct Answer
B. Add the users to Exception Users and enable the service.Explanation
To allow ESXi Shell or SSH access for users with administrator privileges in Strict Lockdown Mode, the administrator should add the users to Exception Users and enable the service. This will exempt the specified users from the restrictions imposed by Strict Lockdown Mode and allow them to access the ESXi Shell or SSH. Granting the users the administrator role alone will not be sufficient as Strict Lockdown Mode prevents direct access, so the exception needs to be added to bypass this restriction.

To reduce the attack vectors for a virtual machine, which two settings should an administrator set tofalse? (Choose two.)
- A.
IdeX:Y.present
- B.
Serial.present
- C.
IdeX:Y.enabled
- D.
Serial.enabled
Correct Answer(s)
A. IdeX:Y.present
B. Serial.presentExplanation
To reduce the attack vectors for a virtual machine, an administrator should set the "ideX:Y.present" and "serial.present" settings to false. By disabling these settings, the virtual machine will not have access to any IDE or serial ports, which can be potential entry points for attackers. Disabling these settings ensures that the virtual machine is more secure and less vulnerable to attacks through these vectors.Rate this question:

Which two groups of settings should be reviewed when attempting to increase the security of virtualmachines (VMs)? (Choose two.)
- A.
Disable hardware devices
- B.
Disable unexposed features
- C.
Disable VMtools devices
- D.
Disable VM Template features
Correct Answer(s)
A. Disable hardware devices
B. Disable unexposed featuresExplanation
To increase the security of virtual machines (VMs), two groups of settings should be reviewed. First, disabling hardware devices is important as it prevents unauthorized access or tampering with the VMs through physical devices. By disabling hardware devices, only authorized personnel can access and control the VMs. Second, disabling unexposed features is crucial as it reduces the attack surface and minimizes the risk of vulnerabilities. Unexposed features may provide potential entry points for attackers, so disabling them ensures that only necessary and secure features are enabled on the VMs.Rate this question:

An administrator has been instructed to secure existing virtual machines in vCenter Server.Which two actions should the administrator take to secure these virtual machines? (Choose two.)
- A.
Disable native remote management services
- B.
Restrict Remote Console access
- C.
Use Independent Non-Persistent virtual disks
- D.
Prevent use of Independent Non-Persistent virtual disks
Correct Answer(s)
B. Restrict Remote Console access
D. Prevent use of Independent Non-Persistent virtual disksExplanation
The administrator should restrict Remote Console access to secure the virtual machines. By limiting access to the console, unauthorized users will not be able to interact with the virtual machines directly. Additionally, the administrator should prevent the use of Independent Non-Persistent virtual disks. These disks do not retain any changes made to them, which can be a security risk as any malicious activity or data breach would not be saved. By preventing their use, the administrator can ensure that all changes made to the virtual machines are persistent and can be audited if necessary.Rate this question:

Which two statements are correct regarding vSphere certificates? (Choose two.)
- A.
ESXi host upgrades do not preserve the SSL certificate and reissue one from the VMware Certificate Authority (VMCA).
- B.
ESXi host upgrades preserve the existing SSL certificate.
- C.
ESXi hosts have assigned SSL certificates from the VMware Certificate Authority (VMCA) during install.
- D.
ESXi hosts have self-signed SSL certificates by default.
Correct Answer(s)
B. ESXi host upgrades preserve the existing SSL certificate.
C. ESXi hosts have assigned SSL certificates from the VMware Certificate Authority (VMCA) during install.Explanation
ESXi host upgrades preserve the existing SSL certificate because the upgrade process does not involve replacing or reissuing the SSL certificate. Instead, it maintains the existing certificate, ensuring continuity in secure communication.
ESXi hosts have assigned SSL certificates from the VMware Certificate Authority (VMCA) during install. This means that during the installation process, the ESXi hosts are issued SSL certificates by the VMware Certificate Authority, ensuring that the communication between the hosts and other components is secure.Rate this question:

Which two solutions require Physical Mode Raw Device Mapping (RDM)? (Choose two.)
- A.
Direct access to the storage array device
- B.
Virtual Machine Snapshots
- C.
Hardware Acceleration
- D.
Guest Clustering across ESXi hosts
Correct Answer(s)
A. Direct access to the storage array device
D. Guest Clustering across ESXi hostsExplanation
Physical Mode Raw Device Mapping (RDM) is required for two solutions: direct access to the storage array device and guest clustering across ESXi hosts.
Direct access to the storage array device allows virtual machines to directly access the storage without going through the virtualization layer, which can be useful for certain applications or storage configurations.
Guest clustering across ESXi hosts requires RDM to provide shared access to the same storage device for multiple virtual machines in a cluster. This allows for high availability and failover capabilities within the cluster.Rate this question:

An administrator decides to change the root password for an ESXi 6.x host to comply with the company'ssecurity policies.What are two ways that this can be accomplished? (Choose two.)
- A.
Use the Direct Console User Interface to change the password.
- B.
Use the passwd command in the ESXi Shell.
- C.
Use the password command in the ESXi Shell.
- D.
Use the vSphere client to update local users.
Correct Answer(s)
A. Use the Direct Console User Interface to change the password.
B. Use the passwd command in the ESXi Shell.Explanation
The Direct Console User Interface (DCUI) is a text-based interface that allows administrators to perform various tasks on an ESXi host, including changing the root password. This can be done by accessing the DCUI directly on the host and navigating through the settings to change the password.
The passwd command in the ESXi Shell is another way to change the root password. The ESXi Shell is a command-line interface that provides access to the underlying operating system of the host. By using the passwd command, administrators can change the root password directly from the shell.
Both methods mentioned provide ways to change the root password on an ESXi host to comply with the company's security policies.Rate this question:
