Exam 70-745: Implementing a Software-Defined Datacenter Practice Test
Exam 70-745 practice addresses software-defined datacenter operations built around Windows Server and Hyper-V. The question bank samples decisions involving virtual networking, storage services, host configuration, and protected virtual machines. These areas connect infrastructure design with tasks such as provisioning workloads, maintaining resilient connectivity, and applying security controls across a virtualized fabric.
Exam overview
About the Exam 70-745: Implementing a Software-Defined Datacenter Exam
Datacenter work in this area involves configuring Hyper-V hosts and virtual machines, choosing ways to reuse prepared images, and balancing host resources when memory is constrained. Network scenarios can involve Software-Defined Networking (SDN), the Network Controller, virtual switches, network virtual appliances, and port access control lists. Storage questions touch on highly available SMB file shares and the roles that provide them. Security decisions include shielding virtual machines against inspection or tampering by the fabric, while operational considerations include consistent time across domain-joined servers and guests. The practice bank also refers to network adapter teaming for resilient virtual switch connectivity and to virtualized network functions that can serve different workloads. Consider how each configuration supports availability, isolation, manageability, and workload requirements rather than memorizing feature names alone.
Sample Practice Questions
Review a selection from this exam's published US Practice Tests practice bank.
A Windows Server datacenter team wants to deploy and manage a virtualized network function as a service that can be instantiated for different workloads. Which approach best fits this goal?
Show answer
Correct answer: ANFV implements network functions in software, allowing them to run on general-purpose compute infrastructure and be deployed or managed as workloads. It does not require a dedicated physical appliance for every service.
A Windows Server administrator needs to configure a Hyper-V host to use a defined amount of memory for the management operating system when virtual machines are under memory pressure. Which setting is most relevant?
Show answer
Correct answer: BHost Resource Protection helps preserve resources for the host by limiting the resources available to virtual machines when the host detects that a VM is causing excessive resource use. Smart Paging is a temporary VM-start mechanism, while memory settings such as minimum memory and weight govern VM memory allocation or priority.
What is the purpose of a network virtual appliance in an SDN environment?
Show answer
Correct answer: AA network virtual appliance implements network services in software, such as routing, firewalling, or load balancing, and can be integrated with virtualized networks.
A Windows Server deployment needs to provide highly available file shares to applications using the SMB protocol. Which role is the most direct fit?
Show answer
Correct answer: CScale-Out File Server is designed to provide continuously available, scale-out SMB file shares, commonly for application data such as Hyper-V or SQL Server workloads. DFS Namespaces organizes paths, FSRM manages file policies, and BranchCache supports content caching.
A Windows Server host needs a protected virtual machine whose state and data are encrypted to help guard against inspection or tampering by the fabric. Which feature is designed for this purpose?
Show answer
Correct answer: AShielded Virtual Machines use protections such as encryption and guarded-fabric controls to help protect VM data and state from unauthorized access, including by potentially compromised fabric administrators.
In a Windows Server datacenter, what is the main benefit of using a consistent time source for domain-joined servers and virtual machines?
Show answer
Correct answer: BConsistent time synchronization supports Kerberos authentication and makes timestamps in logs and events useful for troubleshooting and correlation. Time synchronization does not provide network forwarding, CPU scheduling guarantees, or data replication.
A Hyper-V host has several physical network adapters and needs to combine them into one resilient logical interface for virtual switch connectivity. Which Windows Server feature provides this capability?
Show answer
Correct answer: ANIC Teaming combines multiple network adapters into a team that can provide resilience and, depending on configuration, load distribution for host networking. Network Load Balancing serves a different cluster model, MPIO handles storage paths, and IPsec protects IP traffic.
How to use this practice test
The free practice session draws up to 20 random questions from the 50-question bank. Answer the scenarios as infrastructure decisions, then use the session results to identify which Windows Server, Hyper-V, networking, storage, or security concepts need further review.
Preparation tips
- For SDN questions, distinguish the Network Controller's management role from the functions of virtual switches, network virtual appliances, and virtualized network functions.
- Compare Hyper-V host memory settings with virtual-machine memory configuration; focus on what each setting protects or allocates under memory pressure.
- Trace how virtual switch connectivity depends on physical adapters, teaming, and port ACLs, including the resilience or traffic-control purpose of each feature.
- Review the difference between SMB file-service availability and virtual-machine protection features, and match each to the asset or workload it protects.
- Practice explaining how prepared VM images, consistent time sources, and shielded virtual machines affect provisioning, operations, and fabric security.
