CompTIA SK0-005 CompTIA Server+ Certification Exam Practice Test

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.

Answer : B

SSH (Secure Shell) is a protocol that would most likely be implemented to encrypt data in transit for remote administration. SSH provides secure communication between two devices over an unsecured network by using public-key cryptography and symmetric encryption. SSH can be used to remotely execute commands, transfer files, or tunnel other protocols. Telnet, TFTP, and rlogin are protocols that do not encrypt data in transit and are considered insecure for remote administration.Reference: [CompTIA Server+ Certification Exam Objectives], Domain 2.0: Networking, Objective 2.4: Given a scenario involving network security/access methods, implement an appropriate solution.

Answer : D

Few people are expected to use the database at the same time and users don't need to customize the design of the database.

The server role that the administrator will most likely need to install for a server that will hold large amounts of information and will need to be accessed by multiple users at the same time is database. A database is a collection of structured data that can be stored, queried, manipulated, and analyzed using various methods and tools. A database server is a server that hosts one or more databases and provides access to them over a network. A database server can handle large amounts of information and support concurrent requests from multiple users or applications.

Answer : C

A tower server is a type of server architecture that is best suited to minimize cost when deploying a single server to monitor and record the security cameras at a remote site. A tower server is a standalone server that has a similar form factor and design as a desktop computer. It does not require any special mounting equipment or rack space and can be placed on or under a desk or table. A tower server is suitable for small businesses or remote offices that need only one or few servers for basic tasks such as file sharing, print serving, or security monitoring. A tower server is usually cheaper and easier to maintain than other types of servers, but it may have lower performance, scalability, and redundancy features. A virtual server is a type of server architecture that involves creating and running one or more virtual machines on a physical host using a hypervisor such as Hyper-V or VMware. A virtual server can reduce hardware costs and improve flexibility and efficiency, but it requires additional software licenses and management tools. A blade server is a type of server architecture that involves inserting multiple thin servers called blades into a chassis that provides power, cooling, network, and management features. A blade server can improve performance, density, and scalability, but it requires more initial investment and specialized equipment. A rack mount server is a type of server architecture that involves mounting one or more servers into standardized frames called racks that provide power, cooling, network, and security features

Answer : A

Comprehensive Detailed Explanation with all CompTIA Server+ SK0-005 Study Guide Reference:The most likely cause of a speed mismatch (100Mbps instead of 1Gbps) is a defective or incompatible network cable. Gigabit Ethernet requires at least Cat5e or Cat6 cables; using older cables (e.g., Cat5) or damaged cables can limit speeds to 100Mbps.

Port securityandVLAN misconfigurationwould typically prevent communication entirely, not reduce speed.

Incorrect IP subnetdoes not affect link speed.Checking and replacing the network cable is a logical first troubleshooting step in this scenario.

Answer : D

Phishing is a type of attack that is the most difficult to mitigate with technology. Phishing is a technique of deceiving users into revealing their personal or confidential information, such as passwords, credit card numbers, or bank accounts, by sending them fraudulent emails or messages that appear to be from legitimate sources. Phishing relies on human factors, such as curiosity, greed, or fear, to trick users into clicking on malicious links or attachments, or entering their credentials on fake websites. Technology solutions, such as antivirus software, firewalls, or spam filters, can help detect and block some phishing attempts, but they cannot prevent users from falling victim to social engineering tactics.Reference: [CompTIA Server+ Certification Exam Objectives], Domain 5.0: Security, Objective 5.3: Given a scenario, explain methods and techniques to secure data.

Answer : D

NIC teaming is a feature that allows the use of multiple network interface cards (NICs) as a single logical interface with a single IP address. It can improve the network performance, bandwidth, and redundancy of a server. Verified Reference: [NIC teaming], [Network interface card]
