Explanation:

Reclaim free space: Garbage Collection. Validate and repair data integrity issues: Scrubbing.
Data Deduplication ' s Garbage Collection job is the maintenance job specifically responsible for reclaiming disk space on a deduplicated volume: whenever optimized files are deleted, their referenced chunks in the chunk store are not immediately freed, since other files may still reference the same chunks, so Garbage Collection scans the chunk store, identifies chunks no longer referenced by any file (exactly the situation created when administrators deleted many optimized files during the paused schedule), and removes them to actually return the freed space to the volume, which directly matches the first requirement. The Scrubbing job is the job responsible for data integrity: it scans the chunk store and the deduplicated data for corruption, including damage caused by underlying storage problems such as the bad sectors reported by storage diagnostics here, and where redundant copies of a chunk exist (or where the underlying volume uses a resilient storage configuration), Scrubbing repairs the corrupted data automatically, matching the second requirement exactly. The Optimization job performs the initial and ongoing deduplication of new or changed files into chunks, and the Unoptimization job reverses deduplication entirely by rehydrating all optimized files back to their original, non-deduplicated state; neither job reclaims already-freed chunk space from deleted files, and neither validates or repairs data integrity issues on the chunk store.

Explanation:

Processor configuration: Expose virtualization extensions. Network configuration: Enable MAC address spoofing.
Nested virtualization, running the Hyper-V role inside a VM so that VM itself can host further, nested virtual machines, requires the parent VM ' s virtual processor to expose the hardware virtualization extensions (Intel VT-x/EPT or AMD-V equivalents) that the guest hypervisor inside VM1 needs to create and run its own nested VMs; this is enabled with the -ExposeVirtualizationExtensions $true parameter on Set-VMProcessor, and without it, VM1 ' s own attempt to enable Hyper-V would fail because the guest OS would detect no hardware virtualization support at all. Increasing the number of virtual processors or enabling processor compatibility mode (which is for live-migrating between hosts with different CPU generations) do nothing to expose the extensions nested virtualization depends on. On the networking side, nested VMs inside VM1 use their own, further-virtualized MAC addresses that VM1 ' s own virtual network adapter did not originally advertise to HV1 ' s external switch; unless MAC address spoofing is enabled on VM1 ' s virtual network adapter, HV1 ' s virtual switch will drop outbound frames from those nested VM MAC addresses as spoofed traffic, silently blocking their connectivity to the physical LAN. Enabling NIC Teaming, Router Guard, or port mirroring on VM1 ' s adapter address entirely different scenarios (link aggregation, rogue DHCP/router protection, and traffic monitoring, respectively) and would not allow nested VMs ' distinct MAC addresses to reach the physical network.

Explanation:
Preference extension: Drive Maps
Action: Replace
Group Policy Preferences provides the Drive Maps extension to create and manage mapped network drives for domain users.
The Drive Maps extension can assign drive F to the Finance share on FS1. Security Group item-level targeting ensures that the preference applies only to users who belong to Group1.
The Replace action deletes an existing mapped drive and recreates it during Group Policy refresh. This ensures that the configured mapping is restored even if a user modifies or removes it.
Selecting " Remove this item when it is no longer applied " also ensures that the mapping is removed when the user no longer meets the targeting conditions.
The Create action does not consistently recreate an existing modified mapping, while Update does not delete and rebuild the mapping.
Therefore, Drive Maps with Replace satisfies the requirements.

Explanation:
[Answer choice] can have production checkpoints. = VM1, VM2, and VM3
[Answer choice] can be hibernated. = Only VM1 and VM2
Hyper-V gates certain features by the virtual machine ' s configuration version (the number reported by Get- VM, which reflects which Hyper-V feature set the VM can use, independent of the current host ' s own version as long as the host supports at least that version). Production checkpoints were introduced at VM configuration version 6.2 and have remained supported at every version since; because VM1 (10.0), VM2 (9.0), and VM3 (8.0) are all at or above that 6.2 floor, all three virtual machines can use production checkpoints, regardless of their differing configuration versions. Hibernation support for a Hyper-V virtual machine, however, was introduced later, at configuration version 9.0, and is not available on VMs below that version. VM1 (10.0) and VM2 (9.0) both meet or exceed the 9.0 minimum and can therefore be hibernated, while VM3, at configuration version 8.0, falls below that threshold and cannot be hibernated no matter what host version Server1 is running, since the limitation is inherent to the VM ' s own configuration version rather than to Server1. Administrators who need to enable hibernation on VM3 would first need to run Update- VMVersion against it (which is a one-way, non-reversible upgrade) to bring it to at least version 9.0.
