Paper For Above instruction

1. What happens if you attempt to add workgroup servers to Server Manager?

a. Server Manager allows only servers that are members of an Active Directory Domain Services (AD DS) domain to be managed.

b. Server Manager adds and allows management of any computer, whether a member of an AD DS domain or workgroup.

c. Server Manager will not permit workgroup servers to be added and managed.

d. Server Manager usually allows you to add workgroup servers, but attempts to access the remote server fail with a “Credentials not valid” error.

Justification: The correct answer is (a). Server Manager is designed primarily to manage servers that are part of an Active Directory domain because it relies on domain credentials and policies for remote management. Workgroup computers do not participate in Active Directory, and therefore, Server Manager restricts management to domain-joined servers, ensuring security and proper management practices.

2. Once a server is added to Server Manager, what actions are taken to permit remote server management?

a. No further action is needed. For example, you may immediately use the Add Roles and Features Wizard.

b. No further action is needed, because Windows Remote Management (WinRM) is enabled on the source Windows Server 2012.

c. No further action is needed because WS-Management Protocol is already running.

d. No further action is needed thanks to Windows Management Instrumentation (WMI) and Windows PowerShell.

Justification: The correct answer is (b). Windows Server 2012 has WinRM enabled by default, which facilitates remote management through Server Manager and other management tools. While WMI and PowerShell are also components of remote management, WinRM is the underlying protocol that needs to be enabled and configured for remote connections, making option (b) the most accurate.

3. What is the primary difference between the Windows Server 2012 Server Manager and previous versions?

a. Windows Server 2012 Server Manager allows management of multiple remote servers at once.

b. Windows Server 2012 Server Manager allows management of remote servers, categorized in role groups.

c. Windows Server 2012 Server Manager allows remote management of other servers, including down-level Windows servers.

d. Windows Server 2012 Server Manager has been tested with nearly 100 servers added to the interface.

Justification: The correct answer is (a). The most significant enhancement in Windows Server 2012 Server Manager is its ability to manage multiple servers simultaneously across the network, providing centralized management capabilities. Although categorization and broader support are features, the core advancement is its multi-server management functionality.

4. What functional benefit is derived from creating server groups?

a. Server groups allow administrators to add roles to several servers at once.

b. Server groups allow administrators to navigate and organize several servers at once.

c. Server groups allow administrators to navigate several servers at once.

d. Server groups allow administrators to organize several servers at once.

Justification: The correct answer is (b). Creating server groups helps organize and navigate multiple servers efficiently within Server Manager, improving manageability and oversight. While options (c) and (d) are similar, (b) explicitly emphasizes the organizational and navigational benefits, which are crucial in server management contexts.

5. The security configuration of the Windows PowerShell Web Access Gateway server is crucial, employing a security certificate from a trusted certification authority and userspecific authorization rules. Why are these security measures so crucial?

a. There is often both client and server side security, but only server end measures are controlled.

b. There is no mandatory security on the client side of the application, relying more on server side security.

c. There is no security on the client side of the application, instead relying on robust server side security.

d. There is often both client and server side security, but only client end measures are controlled.

Justification: The correct answer is (b). Security certificates and user-specific rules are essential because they address potential vulnerabilities on the client side and ensure that only authorized users gain access through the Web Access Gateway, which relies heavily on server-side security mechanisms.

6. Hyper-V in Windows Server 2012 is a Type I virtualization architecture. What is the fundamental difference between Hyper-V and older, Type II virtualization architectures?

a. Hyper-V creates environments called partitions, each with its own operating system installed.

b. Its hypervisor designates the first partition as the parent partition and all subsequent partitions as child partitions.

c. Its hypervisor is an abstraction layer and interacts directly with computer hardware, rather than as a host OS application.

d. Computer subsystems such as Plug and Play and power management are managed by Hyper-V’s parent partition.

Justification: The correct answer is (c). Type I hypervisors, like Hyper-V, run directly on hardware, providing efficient resource management and isolation. This contrasts with Type II hypervisors, which run within a host operating system, making direct hardware interaction a key difference.

7. Windows Server 2012 includes Hyper-V in which edition(s)?

a. All editions

b. The Datacenter edition

c. The Standard and Datacenter editions

d. The Essentials, Standard, and Datacenter editions

Justification: The correct answer is (c). Hyper-V is included in both the Standard and Datacenter editions of Windows Server 2012. Other editions, such as Essentials and Foundation, do not include Hyper-V support, focusing more on smaller environments.

8. After installing the Hyper-V role, what is the startup procedure for Windows Server 2012?

a. The newly installed hypervisor starts first, and then loads the operating system as the primary or parent partition.

b. The actual startup procedure is not altered.

c. The newly installed hypervisor starts first, and then loads the operating system as a child partition.

d. The newly installed hypervisor starts second, after the operating system loads as a partition.

Justification: The correct answer is (a). When Hyper-V is installed, the hypervisor loads first during system startup, then the parent (or host) operating system loads as a special partition, which manages the virtual machines.

9. What is the primary purpose of the software package offered by Hyper-V called guest integration services?

a. Guest integration services improves communications between the parent partition and child partitions.

b. Guest integration services resolves compatibility issues of certain guest operating systems experiencing non-functioning features.

c. Guest integration services improves data exchange between the parent partition and child partitions.

d. Guest integration services improves time synchronization between the parent partition and child partitions.

Justification: The correct answer is (a). Guest Integration Services facilitate seamless communication and synchronization between the host and guest operating systems, enabling features like time sync, heartbeat, and data exchange critical for virtual machine operation.

10. What is Resource Monitoring in Windows Server 2012?

a. Resource Monitoring is a PowerShell-based feature that enables you to document virtual machine usage.

b. Resource Monitoring is a Server Manager feature that enables you to monitor virtual machine resources.

c. Resource Monitoring is a PowerShell-based feature that enables you to redistribute virtual machine resources.

d. Resource Monitoring is a Server Manager feature that enables you to document virtual machine communications.

Justification: The correct answer is (b). Resource Monitoring in Windows Server 2012, accessible through Server Manager, provides administrators with insights into resource usage of virtual machines and host servers, facilitating effective management and troubleshooting.

11. Deciding between two virtual disk formats (VHD and VHDX), you need one to accommodate image sizes up to 2 TB (terabytes) and be compatible with both Windows Server 2012’s Hyper-V and Microsoft’s older product, Virtual PC. Which format do you choose and why?

a. VHD, because it supports up to 2 TB image files.

b. VHDX, because it supports file sizes far beyond 2 TB—up to 64 TB.

c. VHD, because it supports both new and old hypervisor products.

d. VHDX, because it supports larger block sizes for tuning storage performance.

Justification: The correct answer is (a). VHD supports up to 2 TB file sizes, making it compatible with both Hyper-V on Windows Server 2012 and previous versions like Virtual PC. VHDX surpasses this size limit but is not backward compatible with Virtual PC, making VHD the suitable choice here.

12. You need to connect a virtual hard disk with a virtual machine (VM). What disk format do you choose and why?

a. VHDX, because it’s the only one available when creating a new disk.

b. VHD or VHDX if using an existing virtual hard disk.

c. VHD with an existing hard disk and a Type II hypervisor product.

d. Either one is possible and applicable.

Justification: The correct answer is (b). When creating or attaching existing virtual disks, both VHD and VHDX formats are viable options, providing compatibility depending on the hypervisor version and disk requirements.

13. You intend to create a new virtual hard disk, specifying a 700 GB VHDX image file with a logical sector size of 4 KB. How do you proceed?

a. With Server Manager, using Hyper-V Manager’s New Disk feature.

b. With the utilities included in Hyper-V’s guest integration services.

c. Those exact specifications are not possible in Hyper-V Manager.

d. With PowerShell, using the New-VHD cmdlet with appropriate parameters.

Justification: The correct answer is (d). Creating a VHDX file with specified size and sector size can be achieved efficiently using PowerShell’s New-VHD cmdlet, which allows detailed configuration options not always available in GUI tools.

14. Is it possible for a VM to access a hard disk directly?

a. No. VMs access virtual hard disks, areas of space on the physical hard disk.

b. Yes. VMs can have “pass-through disks,” a special virtual disk that directly accesses the physical disk if made exclusively available to the VM.

c. No. VMs can never access physical hardware, but only through the hypervisor.

d. Yes. VMs use virtual hard disks, which are essentially the physical hard disks.

Justification: The correct answer is (b). Hyper-V supports pass-through disks, allowing a VM to directly access a physical disk for improved performance or compatibility, bypassing the virtual disk layer.

15. What is a key benefit of using differencing disks?

a. They enable you to use baseline images.

b. They enable you to keep a fixed image in its original state.

c. They allow you to experiment without repercussions.

d. They let you create parent and child-differencing disks.

Justification: The correct answer is (c). Differencing disks are useful for testing and development because they allow changes and experiments without modifying the baseline or parent image, ensuring a stable original environment.
