In which type of attack is falsified information used to redirect users to malicious internet sites?
This type of attack, known as DNS spoofing or DNS cache poisoning, uses falsified information to redirect users to malicious websites. It tricks users into visiting harmful sites without their knowled...
What device is considered a supplicant during the 802.1X authentication process?
In the 802.1X authentication process, a supplicant is the device requesting network access, like a laptop or smartphone. It communicates with an authenticator (switch/AP) and authentication server. Fo...
What Type Of Attack Occurs When Data Goes Beyond The Memory Areas Allocated To An Application?
A buffer overflow attack occurs when data exceeds the memory boundaries allocated to an application, overwriting adjacent memory spaces. This can corrupt data, crash the program, or allow attackers to...
What Are Three Examples Of Administrative Access Controls? (Choose Three.)
Administrative access controls are policies and procedures that manage user access to systems and data. Three examples include role-based access control (RBAC), which assigns permissions based on job...
What are signatures as they relate to security threats?
Signatures in security threats are unique patterns or identifiers (like code snippets) used to detect malware or attacks. They help security tools recognize and block known threats. Regularly updating...
Which Type Of Memory Is Primarily Used As Cache Memory?
Cache memory primarily uses static random-access memory (SRAM) due to its high speed and low latency, enabling faster data access for the CPU compared to dynamic RAM (DRAM). SRAM retains data without...
What is a wireless security mode that requires a RADIUS server to authenticate wireless users?
A wireless security mode that requires a RADIUS server to authenticate users is typically WPA2-Enterprise. It ensures secure access by verifying users through centralized authentication. For detailed...
What is the result of a DHCP starvation attack?
A DHCP starvation attack occurs when an attacker floods a network with fake DHCP requests, exhausting the available IP addresses. This causes legitimate devices to be unable to obtain an IP address, d...
What data is stored in the CMOS memory chip?
CMOS memory chip stores essential system data like BIOS settings, system time, date, and hardware configuration. It helps your computer boot properly and retain settings even when powered off. For mor...
Which network service automatically assigns IP addresses to devices on the network?
The network service that automatically assigns IP addresses to devices is called DHCP (Dynamic Host Configuration Protocol). It simplifies network management by automatically providing IP addresses, g...
Which factor affects the speed of an inkjet printer?
The speed of an inkjet printer depends on factors like print resolution, paper type, ink drying time, and printer hardware. Higher DPI settings slow printing, while draft mode speeds it up. For more p...
What Is The Main Aim Of A Cyber Security Incident Response Team (CSIRT)?
The main aim of a Cyber Security Incident Response Team (CSIRT) is to detect, manage, and mitigate cybersecurity incidents effectively to minimize damage, restore normal operations, and prevent future...
What type of device is able to create physical movement?
Devices like motors, actuators, and robots create physical movement. Motors convert electrical energy into motion, while actuators (e.g., hydraulic or pneumatic) enable precise control. Robots combine...
What Is A Characteristic Of DDR SDRAM?
A characteristic of DDR SDRAM (Double Data Rate Synchronous Dynamic Random-Access Memory) is its ability to transfer data on both the rising and falling edges of the clock signal, effectively doubling...
Which device can scan a document and attach the scan to an email?
A scanner or all-in-one printer can scan documents and attach them to emails. Many modern devices and smartphone apps (like CamScanner) also offer this feature. For more tech tips and study resources,...
Match The Port Number To The Email Protocol.
Matching port numbers to email protocols involves linking specific protocols like SMTP, POP3, and IMAP to their default ports. SMTP (Simple Mail Transfer Protocol) uses port 25 for sending emails, whi...
What would cause an inkjet printer to fail to print any pages?
An inkjet printer may fail to print due to clogged nozzles, empty/low ink, incorrect settings, paper jams, or driver issues. Check ink levels, clean printheads, and verify connections. For more tech t...
How can you keep your personal browsing history hidden from other users on a shared computer?
To hide your browsing history on a shared computer, use private browsing modes (like Chrome’s Incognito or Firefox’s Private Window), clear cache/cookies regularly, and avoid saving passwords. For sec...
What Are Two Ways That IOS Differs From Android? (Choose Two.)
iOS differs from Android in two key ways: closed-source vs. open-source and hardware exclusivity. iOS is proprietary software, exclusively for Apple devices, while Android is open-source, allowing cus...
Which Of The Following Is An Example Of Two Factor Authentication?
Two-factor authentication (2FA) adds an extra layer of security by requiring two different verification methods. An example is logging into an account with a password (first factor) and then entering...
