The BIOS settings are stored in CMOS memory powered by a small battery on the motherboard.
- True
- False
Answer: True
CMOS (Complementary Metal-Oxide-Semiconductor) memory stores BIOS/UEFI settings (boot order, system time, hardware config) and is powered by a coin-cell battery (CR2032). If battery dies, settings reset to defaults and system clock loses time. Replacing battery restores persistent storage.
The protocol that automatically assigns IP addresses to devices on a network is called ________.
- SWAYAM
- FAME
- DHCP
- NIDHI
Answer: DHCP

The technology that allows a single physical server to run multiple isolated operating systems is called ________.
- Doping
- Web Application / DAST
- Rectifier
- Virtualization
Answer: Virtualization
Virtualization uses hypervisor software to create multiple virtual machines (VMs) on one physical server, each running independent OS. Improves resource utilization, enables testing, disaster recovery, and cloud infrastructure. Types: full virtualization, para-virtualization, containerization (Docker).
Which practice helps prevent unauthorized access to Wi-Fi networks?
- Using default password
- Disabling SSID broadcast
- WEP encryption
- Open network
Answer: Disabling SSID broadcast
Disabling SSID broadcast hides network name from public scans, adding obscurity layer. However, strong security requires WPA3 encryption, complex password, MAC filtering, and regular firmware updates. WEP is broken; default passwords are easily guessable; open networks offer no protection.
A static IP address never changes, while a dynamic IP address can change periodically.
