Scenario: A Citrix Engineer is designing a Provisioning Services environment based on the following environmental factors:
-A large number of target devices are spread over multiple subnets.
-The subnets include non-Provisioning Services machines that rely on starting up over the network
-A security mandate prohibits the use of TFTP.
-Provisioning Services 7.6 Update 1 is being used to maintain LTSR compliance.
Which Provisioning Services boot method is appropriate for the target devices?
Given the environmental factors, the most appropriate Provisioning Services boot method is BDM Disk Partition. This method allows for booting without the need for TFTP, which is prohibited by the security mandate. It’s also suitable for a large number of target devices spread across multiple subnets, as it eliminates the reliance on network-based boot methods like PXE or TFTP. Additionally, since Provisioning Services 7.6 update 1 supports Boot Device Manager (BDM), using a disk partition provides a stable and compliant solution.
I think the answer is "D" - BDM Disk Partition. "As of XenDesktop version 7.x, when using XenDesktop setup wizard we can create and assign a small BDM hard disk partition, which will be attached to the virtual machine as a separate virtual disk. Using this method the above mentioned two-stage approach is no longer needed because partition already contains all the PVS drivers. This way all the information needed will be directly available without the need of PXE,TFTP & DHCP." https://support.citrix.com/article/CTX227725 BIOS Embedded option is specifically for certain OEM physical workstations that have been preconfigured with the bootstrap file embedded within the target device BIOS at the factory.
BDM Disk Partition should be the best option. "Provisioning Services has included support for a Boot Device Manager (BDM) Partition since version 7.0" https://www.atumvirt.com/2016/06/updating-your-boot-device-manager-bdm-partition-with-provisioning-services-7-9/
I believe C is correct here. BDM ISO is a two staged boot, the second stage of which uses TFTP. DHCP options uses TFTP, and BDM Disk Partition I believe only became a viable option in Provisioning Services 7.9 https://www.atumvirt.com/2016/06/updating-your-boot-device-manager-bdm-partition-with-provisioning-services-7-9/ BIOS Embedded is an alternative to using PXE, the Boot Device Manager (BDM) can create a bootstrap file on a local hard drive, USB flash drive, or ISO image. The bootstrap file will then be used to boot the target device. https://docs.citrix.com/en-us/legacy-archive/downloads/provisioning-services-7-6.pdf
