• Question 76:

  An administrator is configuring load-balancing settings in Horizon Console for a RDSH Farm. Which two check boxes can be selected to influence the load balancing behavior? (Choose two.)

  A. The floating dynamic host profile setting, created in the vSphere profile section.

  B. The use custom script setting for customized RDSH load balancing.

  C. The Include Session Count setting to include the session count on the RDSH for load balancing.

  D. The Horizon DRS setting for fully automated vSphere load balancing.

  Correct Answer: BC

  Load balancing is a feature that allows administrators to distribute the load of published desktop and application sessions across multiple RDS hosts in a farm. Load balancing can improve the performance and availability of the sessions and the hosts. Horizon offers two ways of configuring load balancing for RDS hosts: using load balancing settings in Horizon Console or using custom load balancing scripts. The load balancing settings in Horizon Console allow administrators to define how Horizon calculates the server load index, which indicates the load on each RDS host. The server load index can range from 0 to 100, where 0 represents no load and 100 represents full load. A server load index of -1 indicates that load balancing is disabled. Horizon uses the server load index to determine which RDS host is the best candidate for placing a new session request. The load balancing settings in Horizon Console include the following check boxes that can be selected to influence the load balancing behavior: The use custom script setting for customized RDSH load balancing: This setting allows administrators to override the default behavior of the load balancing settings and control the placement of new sessions by writing and configuring custom load balancing scripts. The custom scripts must write the server load index to a specific registry key on each RDS host. Horizon will use the value from the registry key instead of calculating it from the other settings. The Include Session Count setting to include the session count on the RDSH for load balancing: This setting allows administrators to include the number of sessions (connected, pending, and disconnected) on each RDS host as a factor in calculating the server load index. By default, Horizon uses the following formula to calculate the server load index based on the session count: (connected sessions + pending sessions + disconnected sessions)/ (maximum session count). If the maximum session count is configured as unlimited, Horizon falls back to using the absolute number of total sessions. The other options are not check boxes that can be selected in the load balancing settings in Horizon Console: The floating dynamic host profile setting, created in the vSphere profile section: This option is not related to load balancing for RDS hosts, but rather to dynamic environment manager for instant-clone desktops. A dynamic host profile is a vSphere profile that contains configuration settings for instant-clone desktops, such as network settings, domain join settings, and customization scripts. A floating dynamic host profile is a type of dynamic host profile that applies to floating desktop pools, where users are assigned a random desktop from a pool at each login. The Horizon DRS setting for fully automated vSphere load balancing: This option is not related to load balancing for RDS hosts, but rather to distributed resource scheduler (DRS) for vSphere clusters. DRS is a feature that monitors and balances the CPU and memory resources across multiple ESXi hosts in a cluster. DRS can also migrate virtual machines between hosts using vMotion to optimize resource utilization and performance. Horizon DRS is an extension of DRS that integrates with Horizon and provides additional capabilities, such as affinity rules, maintenance mode, and power management. Horizon DRS can be configured with different automation levels, such as fully automated, partially automated, or manual.

• Question 77:

  On a VMware vCenter managed virtual machine, how does the VMware Horizon Agent know which Connection Server it should register with during the Instant Clone pool creation process?

  A. Administrator provides this information in the "Add Pool" creation wizard.

  B. Horizon Agent retrieves this information from an DNS SRV record.

  C. Administrator provides this information in the Horizon Agent Installation Wizard on the master image.

  D. Horizon Agent queries VMware Tools for a Guestlnfo Variable during the cloning process.

  Correct Answer: D

  On a VMware vCenter managed virtual machine, the VMware Horizon Agent knows which Connection Server it should register with during the Instant Clone pool creation process by querying VMware Tools for a Guestlnfo Variable during the cloning process. The Guestlnfo Variable is a custom property that is set on the parent virtual machine and contains the FQDN of the Connection Server. When the parent virtual machine is cloned, the Guestlnfo Variable is copied to the clone and read by the Horizon Agent. The Horizon Agent then registers with the Connection Server specified in the Guestlnfo Variable12. The other options are not correct for this scenario: Administrator provides this information in the "Add Pool" creation wizard. This option is not correct because the administrator does not need to provide the Connection Server information in the "Add Pool" creation wizard. The administrator only needs to select the vCenter Server, data center, cluster, resource pool, datastore, network, and snapshot of the parent virtual machine. The Connection Server information is already embedded in the parent virtual machine as a Guestlnfo Variable3. Horizon Agent retrieves this information from an DNS SRV record. This option is not correct because the Horizon Agent does not use DNS SRV records to find the Connection Server during the Instant Clone pool creation process. DNS SRV records are used by Horizon Client devices to discover Connection Servers when they connect to a Horizon environment. DNS SRV records are optional and can be configured by the administrator to simplify client connections4. Administrator provides this information in the Horizon Agent Installation Wizard on the master image. This option is not correct because the administrator does not need to provide the Connection Server information in the Horizon Agent Installation Wizard on the master image. The administrator only needs to select the features and options that are required for the desktop pool, such as VMware Horizon Instant Clone Agent, VMware Dynamic Environment Manager, VMware App Volumes, and so on. The Connection Server information is set on the master image after it is converted to a parent virtual machine by using a PowerShell script5. References: Instant Clones: How Does It Work?

• Question 78:

  Which pre-requisite should be met before installing the Horizon Connection Server?

  A. The host system must be a vSphere VM with a static IP address.

  B. Use a domain user account with administrator privileges on the Horizon Connection Server.

  C. An SSL server certificate must be installed on the Horizon Connection Server.

  D. Install AD DS and AD LDS Tools on the Horizon Connection Server.

  Correct Answer: B

  One of the prerequisites for installing the Horizon Connection Server is to use a domain user account with administrator privileges on the system. This is because the installer needs to access and modify certain system files and registry settings, as well as create and configure the VMware Horizon View services. The installer also authorizes an Administrators account that has full administration rights for the Horizon environment, including the right to install replicated Connection Server instances. The other options are not prerequisites for installing the Horizon Connection Server. The host system can be a physical or virtual machine, but it must have an IP address that does not change. An SSL server certificate is not required for the initial installation, but it is recommended to replace the default self-signed certificate with a valid certificate from a trusted CA after the installation. AD DS and AD LDS Tools are not required for installing the Horizon Connection Server, but they can be useful for troubleshooting and managing the ADAMdatabase that stores the Horizon configuration data.

• Question 79:

  Which vCenter privileges are required only for instant clones VMs with a Trusted Platform Module (vTPM) device?

  A. Upgrade virtual machine compatibility

  B. Manage KM5

  C. Configure Host USB device

  D. Manage custom attributes

  Correct Answer: B

  A Trusted Platform Module (vTPM) is a virtualized version of a physical TPM device that provides enhanced security for virtual machines. A vTPM device can be added to a virtual machine to enable features such as encryption, attestation,

  and key management. A vTPM device requires a Key Management Server (KMS) to store and manage the encryption keys.

  To create instant clones VMs with a vTPM device, the vCenter Server user must have certain privileges in addition to those required for instant clones without a vTPM device. One of these privileges is Manage KMS, which allows the user to

  perform cryptographic operations on the vTPM device, such as cloning, decrypting, encrypting, migrating, and registering. The Manage KMS privilege is part of the Cryptographic operations privilege group on vCenter Server.

  The other options are not required only for instant clones VMs with a vTPM device:

  Upgrade virtual machine compatibility: This privilege allows the user to upgrade the virtual hardware version of a virtual machine to support new features and capabilities. This privilege is required for instant clones VMs regardless of whether

  they have a vTPM device or not.

  Configure Host USB device: This privilege allows the user to configure USB devices on an ESXi host and attach them to a virtual machine. This privilege is not related to vTPM devices or instant clones VMs.

  Manage custom attributes: This privilege allows the user to create, edit, and delete custom attributes for vCenter Server objects. Custom attributes are user-defined fields that can store additional information about objects. This privilege is not

  related to vTPM devices or instant clones VMs.

• Question 80:

  In a load balanced Horizon POD with three Connection Servers, there are 450 active Blast sessions connected. What happens if one of these Connection Servers runs into an unplanned outage?

  A. All 450 active sessions are disconnected, and have to re-connect again by the end-user.

  B. All active sessions will stay connected, because HTTPS Secure Tunnel and Blast Secure Gateway are disabled.

  C. All 450 active session are logged off immediately.

  D. Only the active sessions from the failed Connection Server are disconnected, because HTTPS Secure Tunnel is disabled.

  Correct Answer: D

  In a load balanced Horizon POD with three Connection Servers, there are 450 active Blast sessions connected. If one of these Connection Servers runs into an unplanned outage, only the active sessions from the failed Connection Server are disconnected, because HTTPS Secure Tunnel is disabled. This means that the other two Connection Servers can still handle the remaining sessions without interruption. The HTTPS Secure Tunnel is a feature that allows Horizon Client devices to establish secure connections to virtual desktops and applications through the Connection Server. When this feature is enabled, all the display protocol traffic is tunneled through the Connection Server, which acts as a proxy between the client and the desktop. This increases the security and simplifies the network configuration, but also adds some overhead and dependency on the Connection Server availability1. When this feature is disabled, the Horizon Client devices connect directly to the desktops using their IP addresses or hostnames, bypassing the Connection Server. This reduces the load and dependency on the Connection Server, but also requires more network configuration and firewall rules to allow direct access to the desktops2. The Blast Secure Gateway is a similar feature that allows Horizon Client devices to establish secure connections to virtual desktops and applications using the Blast Extreme protocol through the Connection Server. When this feature is enabled, the Blast Extreme traffic is tunneled through the Connection Server, which acts as a gateway between the client and the desktop. When this feature is disabled, the Horizon Client devices connect directly to the desktops using Blast Extreme3. In this scenario, both HTTPS Secure Tunnel and Blast Secure Gateway are disabled, which means that the Horizon Client devices connect directly to the desktops using Blast Extreme. Therefore, if one of the Connection Servers fails, only the sessions that were authenticated by that Connection Server are affected. The other sessions can continue without interruption, as long as they can reach their desktops directly4. The other options are not correct for this scenario: All 450 active sessions are disconnected, and have to re-connect again by the end-user. This would be true if HTTPS Secure Tunnel or Blast Secure Gateway were enabled, and all the display protocol traffic was tunneled through the Connection Server. In that case, any failure of a Connection Server would disconnect all the sessions that were using it as a proxy5. All active sessions will stay connected, because HTTPS Secure Tunnel and Blast Secure Gateway are disabled. This would be true if there was no dependency on the Connection Server after authentication. However, even with HTTPS Secure Tunnel and Blast Secure Gateway disabled, there is still some communication between the Horizon Client and the Connection Server for session management and heartbeat monitoring. If a Connection Server fails, these communications are lost and the sessions are terminated. All 450 active session are logged off immediately. This would be true if there was a global setting in Horizon Console to log off users when a Connection Server fails. However, there is no such setting in Horizon Console. The default behavior is to disconnect users when a Connection Server fails, not log them off.
