What Are Two Functions Of Hypervisors? (Choose Two.)
Hypervisors perform two primary functions: creating and managing virtual machines (VMs) by abstracting physical hardware resources, and isolating VMs from each other to ensure security and stability....
Which statement describes an important characteristic of a site-to-site VPN?
A site-to-site VPN securely connects two or more networks over the internet, allowing data to travel between them as if they were on the same local network. This ensures encrypted communication, provi...
Which Port Allows For The Transmission Of High Definition Video Using The Displayport Protocol?
The DisplayPort protocol transmits high-definition video primarily through port number 5000 (UDP/TCP), though some implementations may use alternative ports. DisplayPort itself is a digital display in...
Match The File System With The Respective Description.
The keyword "Match The File System With The Respective Description" refers to an activity or question format where users pair different file systems (e.g., NTFS, FAT32, ext4) with their correct charac...
Which statement describes a characteristic of SRAM in a PC?
SRAM (Static Random Access Memory) in a PC is faster and more reliable than DRAM, as it doesn't require refreshing. It’s used in cache memory for quick data access. Learn more about its characteristic...
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...
