Question 1

Which of the following technologies would allow an administrator to build a software RAID on a Windows server?



Answer : B

Dynamic disk is a technology that allows an administrator to build a software RAID on a Windows server. Dynamic disk is a type of disk management that supports creating volumes that span multiple disks, stripe data across disks, mirror data between disks, or use parity for fault tolerance. Dynamic disk can be used to create RAID 0 (striping), RAID 1 (mirroring), RAID 5 (striping with parity), or spanned volumes on Windows servers. Logical volume management is a technology that allows creating and resizing logical volumes on Linux servers. GPT (GUID Partition Table) is a standard for defining the partition structure on a disk. UEFI (Unified Extensible Firmware Interface) is a specification for the interface between the operating system and the firmware.

Question 2

Which of the following is used for fail over, providing access to all the services currently in use by an organization without having to physically move any servers or employees?



Answer : A

The solution that is used for failover, providing access to all the services currently in use by an organization without having to physically move any servers or employees, is the cloud. The cloud is a term that refers to a network of remote servers that are hosted on the Internet and provide various services, such as storage, computing, networking, and applications. The cloud can be used for failover, which is a backup operation that automatically switches to a standby system or service in case of a failure or disruption of the primary system or service. By using the cloud for failover, an organization can ensure continuous availability and accessibility of its services without requiring any physical relocation or intervention.


Question 3

Which of the following types of locks utilizes key fobs or key cards held against a sensor/reader to gain access?



Answer : C

Lock Type:The type of lock utilizing key fobs or key cards is anelectronic door lock(Option C).

Electronic locks use electronic credentials (such as key cards) for access control.


Question 4

Which of the following licensing models allows the greatest number of concurrent Windows VMS to run on a host for the lowest cost?



Answer : A

The answer to this question may depend on several factors, such as the number and type of Windows VMs, the number and type of host machines, the number and type of users, and the specific licensing terms and conditions of each licensing model. However, based on the information available from the web search results, one possible answer is per user.

Per user licensing model is a licensing model that allows a user to access Windows VMs from any device, regardless of the number of devices or VMs. Per user licensing model is available for Windows 10 Enterprise E3/E5, Windows VDA E3/E5, and Microsoft 365 F3/E3/E5. Per user licensing model may offer the greatest number of concurrent Windows VMs to run on a host for the lowest cost if the following conditions are met:

The user needs to access multiple Windows VMs from different devices, such as desktops, laptops, tablets, or smartphones.

The user needs to access Windows VMs that run different versions or editions of Windows, such as Windows 10 Enterprise, Windows 10 Pro, or Windows 7 Enterprise.

The user needs to access Windows VMs that run on different types of host machines, such as physical servers, virtual servers, or cloud servers.

The user does not need to access Windows VMs that run on dedicated hardware or have specific performance or security requirements.

According to the web search results1, per user licensing model costs $84 per user per year for Windows 10 Enterprise E3, $168 per user per year for Windows 10 Enterprise E5, $100.80 per user per year for Windows VDA E3, and $196.80 per user per year for Windows VDA E5.These prices are based on the Open License Program and may vary depending on the volume and agreement level2

Per core licensing model is a licensing model that requires a license for each core of the processor on the host machine that runs Windows VMs. Per core licensing model is available for Windows Server 2022 Datacenter andStandard editions. Per core licensing model may offer a lower cost than per user licensing model if the following conditions are met:

The host machine has a low number of cores or a high core density.

The host machine runs a high number of Windows VMs with low resource consumption.

The host machine runs only Windows Server VMs with the same edition as the host machine.

According to the web search results2, per core licensing model costs $6,155 for 16 core licenses for Windows Server 2022 Datacenter edition and $1,069 for 16 core licenses for Windows Server 2022 Standard edition.These pricesare suggested retail prices and may vary depending on the reseller2

Per instance licensing model is a licensing model that requires a license for each instance of Windows that runs on a host machine or a VM. Per instance licensing model is available for Windows Server 2022 Essentials edition and some older versions of Windows Server. Per instance licensing model may offer a lower cost than per user or per core licensing model if the following conditions are met:

The host machine runs only one instance of Windows Server with low resource consumption.

The host machine does not need to run any other VMs or applications.

The host machine does not need any advanced features or functions that are available in Datacenter or Standard editions.

According to the web search results2, per instance licensing model costs $501 for one server license for Windows Server 2022 Essentials edition.This price is suggested retail price and may vary depending on the reseller2

Per concurrent user licensing model is a licensing model that allows a certain number of users to access Windows VMs at the same time, regardless of the number of devices or VMs. Per concurrent user licensing model is not available for any current version of Windows or Windows Server. Per concurrent user licensing model was available for some older versions of Windows Server Terminal Services or Remote Desktop Services, but it was discontinued due to complexity and compliance issues. Therefore, per concurrent user licensing model cannot be used for running Windows VMs on a host.


Question 5

The management team has mandated the use of data-at-rest encryption on all corporate servers. Using this encryption paradigm will ensure:



Answer : B

Data-at-rest encryption is a method of encrypting data while it is stored on a storage device, such as a hard drive, an SSD, or a tape library. This ensures that if the data is stolen or lost, it will be unreadable without the encryption key. Data-at-rest encryption does not protect data while it is in transit over the network, in use by the CPU or memory, or attached to an email.


Question 6

A certain application initially uses 1TB of drive space, but this is expected to double each year for the next two years. Which of the following is the minimum number of 1TB drives that are needed in a RAID 5 configuration?



Answer : C

RAID 5 is a storage configuration that uses striping with parity, providing both improved performance and fault tolerance. It requires a minimum of three disks, where data and parity information are distributed across all drives. The storage capacity of a RAID 5 array is calculated as (N - 1) * S, where N is the number of drives, and S is the size of each drive.

Storage Requirements:

Initial Storage: 1TB

After 1 Year: Doubles to 2TB

After 2 Years: Doubles again to 4TB

To accommodate 4TB of data in a RAID 5 setup, we use the formula:

(N - 1) * 1TB 4TB

Solving for N:

N - 1 4

N 5

Therefore, a minimum of 5 drives, each 1TB in size, is required to meet the projected storage needs. This configuration will provide a total usable capacity of 4TB, with 1TB allocated for parity to ensure fault tolerance.

Question 7

Which of the following would MOST likely be part of the user authentication process when implementing SAML across multiple applications?



Answer : A

The term that is most likely part of the user authentication process when implementing SAML across multiple applications is SSO. SSO (Single Sign-On) is a way for users to be authenticated for multiple applications and services at once. With SSO, a user signs in at a single login screen and can then use a number of apps without having to enter their credentials again. SSO improves user experience and security by reducing password fatigue and phishing risks. SAML (Security Assertion Markup Language) is a protocol that enables SSO by providing a standardized way to exchange authentication and authorization data between an identity provider (IdP) and a service provider (SP). SAML uses XML-based messages called assertions to communicate user identity and attributes between parties.
