SEC MCQ 1 / 8 Which feature of IPv6 addresses the main problem of IPv4? A. Uses 32 bits for addresses, providing about 4.3 billion possibilities B. Requires NAT for all networks to simplify connectivity C. Has 128 bits, offering practically unlimited addresses to avoid exhaustion D. Includes a variable header size for more efficient processing 2 / 8 Device drivers are necessary because: A. The OS can directly understand all hardware designs without translation B. They only run in user mode to prevent system crashes C. They are built-in for all devices and never need installation D. Hardware manufacturers use different designs, so drivers translate OS commands to device-specific instructions 3 / 8 What is a key advantage of CLI over GUI according to the comparison table? A. It is more user-friendly for beginners with graphics and animations B. It uses higher resources but allows drag-and-drop for files C. It is excellent for automation through scripts and has low resource usage D. It is slower for experts but provides better precision in clicking 4 / 8 In the context of operating system services, what does 'Resource Allocation' primarily involve? A. Loading programs into memory and terminating them B. Deciding which process gets CPU time, memory, or I/O devices C. Organizing files into directories and setting permissions D. Providing a command line interface for user interaction 5 / 8 Which of the following best describes a monolithic kernel, as compared to a microkernel? A. Runs all services in user mode for better security but slower performance B. Includes everything like file systems and drivers in kernel mode, making it fast but prone to system crashes if one part fails C. Only handles basic scheduling, with other services in kernel mode for efficiency D. Is used exclusively in desktop OS like Windows 10, not in servers 6 / 8 What is the primary role of the kernel in an operating system? A. To provide a graphical user interface for users B. To act as a bridge between applications and hardware, managing processes, memory, and devices C. To handle only file system operations like creating directories D. To optimize network connections using TCP/IP protocols 7 / 8 Which of the following best describes a monolithic kernel, as compared to a microkernel? A.
