Which Hyper-V virtual switch type allows VMs to communicate with each other and the host but not with external networks?
Answer: Internal virtual switch
An internal virtual switch allows communication between VMs and the Hyper-V management OS but provides no connectivity to external networks.
Which Hyper-V storage type provides the best I/O performance for intensive workloads by bypassing virtualization overhead?
Answer: Pass-through disk
Pass-through disks allow VMs to access physical storage directly without any virtual disk file abstraction, delivering the best possible I/O performance.
What is a differencing disk in Hyper-V?
Answer: A virtual disk that stores only changes relative to a parent disk
A differencing disk is linked to a parent disk and stores only the blocks that have changed, reducing storage consumption for derived VMs.
Which feature allows a physical network adapter to present virtual functions directly to VMs, bypassing the virtual switch?
Answer: SR-IOV (Single Root I/O Virtualization)
SR-IOV partitions a physical NIC into virtual functions that can be assigned directly to VMs, bypassing the Hyper-V virtual switch for reduced latency.
What native Windows Server 2012 feature combines multiple network adapters for bandwidth aggregation and failover?
Answer: NIC Teaming (LBFO)
NIC Teaming (Load Balancing and Failover) is a built-in Windows Server 2012 feature that aggregates multiple NICs for increased throughput and redundancy.
What does the Hyper-V Virtual Machine Queue (VMQ) feature do?
Answer: Delivers network packets directly to a VM's memory to reduce host CPU overhead
VMQ allows a physical NIC to deliver network packets directly into a VM's memory buffer, offloading CPU processing and improving network throughput.
