220-1102 Exam Dumps - CompTIA A+ Questions and Answers

DNS (domain name system) is a protocol that translates domain names to IP addresses. If the computer has an incorrect DNS address assigned, it will not be able to resolve the domain names of web-based applications and access them. A firewall, a VLAN (virtual local area network) and a browser cache are not the most likely reasons for the issue, since the computer can ping known IP addresses on the internet and receive a response.

EOL (end-of-life) is a term that indicates a vendor no longer supports a product. It means that the product will no longer be sold, updated or patched by the vendor, and that the users should migrate to a newer version or alternative product. AUP (acceptable use policy), EULA (end-user license agreement) and UAC (user account control) are not terms that indicate a vendor no longer supports a product.

A VPN (virtual private network) is a protocol that creates a secure tunnel between two devices over the internet, hiding their IP addresses and encrypting their traffic. DNS (domain name system) is a protocol that translates domain names to IP addresses. IPS (intrusion prevention system) is a device that monitors and blocks malicious network traffic. SSH (secure shell) is a protocol that allows remote access and command execution on another device.

The correct answers are A and D. Zombies and botnets are types of infections that allow malicious actors to remotely control infected computers and use them to launch distributed denial-of-service (DDoS) attacks against a target. A DDoS attack is a type of cyberattack that aims to overwhelm a server or a network with a large volume of traffic from multiple sources, causing it to slow down or crash.

A keylogger is a type of malware that records the keystrokes of a user and sends them to a remote server, often for the purpose of stealing passwords, credit card numbers, or other sensitive information.

Adware is a type of software that displays unwanted advertisements on a user’s computer, often in the form of pop-ups, banners, or redirects. Adware can also collect user data and compromise the security and performance of the system.

Ransomware is a type of malware that encrypts the files or locks the screen of a user’s computer and demands a ransom for their restoration. Ransomware can also threaten to delete or expose the user’s data if the ransom is not paid.

Spyware is a type of software that covertly monitors and collects information about a user’s online activities, such as browsing history, search queries, or personal data. Spyware can also alter the settings or functionality of the user’s system without their consent.

AutoRun is a feature of Windows that automatically executes a program or file when a removable media such as a USB drive is inserted into the computer. Disabling AutoRun can prevent a USB drive containing malicious software from covertly installing malware on a workstation, as it would require the user to manually open the drive and run the file. Restricting user permissions can also prevent a USB drive containing malicious software from covertly installing malware on a workstation, as it would limit the user’s ability to execute or install unauthorized programs or files. Installing a host-based IDS, restricting log-in times, enabling a BIOS password, updating the password complexity, and updating the antivirus definitions are not actions that can directly prevent this incident from happening again.

One of the possible ways to access the user’s computer remotely is to use RDP, which stands for Remote Desktop Protocol. RDP is a protocol that allows a user to connect to another computer over a network and use its graphical interface. RDP is commonly used for remote desktop software, such as Microsoft Remote Desktop Connection1. To use RDP, the user’s computer must run RDP server software, and the technician must run RDP client software. The technician can then enter the user’s IP address or hostname, and provide the appropriate credentials to log in to the user’s computer. Once connected, the technician can view and control the user’s desktop, and review the Outlook settings.

EFS (Encrypting File System) is a feature that allows a user to encrypt a single folder or file on a Windows PC. It uses a public key encryption system to protect the data from unauthorized access. FAT32 and exFAT are file system formats that do not support encryption. BitLocker is a feature that encrypts the entire drive, not a single folder or file.

APFS stands for Apple File System and it is the default filesystem type for macOS since High Sierra (10.13) version1. APFS is optimized for flash storage and supports features such as encryption, snapshots, cloning, and space sharing1.

FileVault is a macOS utility that uses AES-128 (Advanced Encryption Standard) to encrypt the startup disk of a Mac computer. It protects the data from unauthorized access if the computer is lost or stolen. fdisk and Diskpart are disk partitioning utilities for Linux and Windows, respectively. Disk Utility is another macOS utility that can perform disk management tasks, such as formatting, resizing, repairing, etc. Verified References: https://www.comptia.org/blog/what-is-filevault https://www.comptia.org/certifications/a

Shoulder surfing is a threat that involves someone looking over another person’s shoulder to observe their screen, keyboard, or other sensitive information. Shoulder surfing can be used to steal passwords, personal identification numbers (PINs), credit card numbers, or other confidential data. The use of a privacy screen on a computer can help prevent shoulder surfing by limiting the viewing angle of the screen and making it harder for someone to see the screen from the side or behind. Impersonation, whaling, and tailgating are not threats that can be prevented by using a privacy screen on a computer.

Zombies and botnets are terms that describe the types of infections that can cause internal workstations to participate in a DDoS (distributed denial-of-service) attack. A DDoS attack is a malicious attempt to disrupt the normal functioning of a website or a network by overwhelming it with a large amount of traffic from multiple sources. Zombies are infected computers that are remotely controlled by hackers without the owners’ knowledge or consent. Botnets are networks of zombies that are coordinated by hackers to launch DDoS attacks or other malicious activities. Keylogger, adware, ransomware, and spyware are not types of infections that can cause internal workstations to participate in a DDoS attack.

A corporate security policy can restrict a corporate-managed mobile device from updating its OS automatically, even if the auto-update feature is turned on. This can be done to prevent compatibility issues, security risks or performance problems caused by untested or unwanted updates. The device administrator can control when and how the updates are applied to the device. The device not having enough free space, needing domain administrator confirmation or being incompatible with the newest version of the OS are not likely causes of the issue, since the user would receive an error message or a notification in those cases.

An equipment lock is a physical security device that attaches a laptop to a fixed object, such as a desk or a table, with a cable and a lock. This can prevent the laptop from being stolen by unauthorized persons. Encryption, LoJack, multifactor authentication and bollards are other security measures, but they do not physically prevent theft.
