OS Process Management

Question 1

Which type of disk initialization is limited to 4 partitions?
A. GPT
B. MBR
C. HSM
D. TPM

Answer 1

B. MBR
MBR (Master Boot Record) disk initialization is limited to a maximum of 4 primary partitions. However, it is possible to create more than 4 partitions by using an extended partition, which can contain logical partitions, but the total number of partitions is still constrained by the structure of MBR.

Question 2

Which Linux command can be used to view BIOS version information?
A. lsblk
B. lsusb
C. cpuinfo
D. dmidecode

Answer 2

D. dmidecode
The dmidecode command is used to retrieve hardware information from the system’s BIOS or UEFI, including the BIOS version. You can run dmidecode with appropriate privileges to view detailed system information, including the BIOS version.
A. lsblk: Lists information about block devices (e.g., hard drives), but not BIOS version information.
B. lsusb: Lists USB devices, not BIOS details.
C. cpuinfo: Displays information about the CPU, not the BIOS version.

Question 3

What is wrong with this Linux command?
sudo status service ssh
A. ‘sudo’ must be removed
B. The words ‘status’ and ‘service’ must be changed
C. ‘ssh’ is not a valid daemon name
D. ‘service’ should be ‘serviceunit’

Answer 3

B. The words ‘status’ and ‘service’ must be changed
The correct syntax for checking the status of a service using the service command is:
sudo service ssh status

Question 4

Which tool can be used to view and modify the Windows registry?
A. Regedit
B. RDP
C. CertUtil
D. MMC

Answer 4

A. Regedit
Regedit (Registry Editor) is the built-in tool in Windows that allows users to view and modify the Windows registry. It provides a graphical interface to navigate, search, and make changes to the registry, which stores system configuration settings.

Question 5

Which Linux runlevel reboots a system?
A. 0
B. 6
C. 3
D. 5

Answer 5

B. 6
In Linux, runlevels are used to define the state of the system. The runlevel that specifically causes the system to reboot is runlevel 6.

Here’s what each runlevel generally represents:
0: Halt (shutdown the system)
1: Single-user mode (used for maintenance, with minimal services)
2: Multi-user mode without networking
3: Multi-user mode with networking (full multi-user text mode)
4: Not used or reserved for custom configurations
5: Multi-user mode with graphical interface (GUI)
6: Reboot (this will restart the system)

Question 6

Which hardware security component can be used to store BitLocker encryption keys?
A. SLA
B. TPM
C. PCI
D. HSM

Answer 6

B. TPM
TPM (Trusted Platform Module) is a hardware-based security component that is commonly used to store cryptographic keys, including BitLocker encryption keys, in a secure manner. It provides a protected area on the motherboard to store keys and other sensitive data, making it resistant to tampering or unauthorized access.

Question 7

How does a Window data collector set (DCS) differ from using Performance Monitor?
A. A DCS can be scheduled
B. Performance Monitor can be scheduled
C. Performance Monitor cannot monitor memory utilization
D. A DCS cannot monitor memory utilization

Answer 7

A. A DCS can be scheduled
Data Collector Sets (DCS) in Windows Performance Monitor are used to collect and store performance data over time, and they can be scheduled to start and stop automatically at specified times. This allows for more advanced and automated monitoring tasks, including data collection over extended periods.

Performance Monitor (PerfMon) is a real-time tool that can be used to monitor performance, but it typically requires manual operation unless a Data Collector Set is used. While Performance Monitor can be scheduled, this scheduling is typically done via Data Collector Sets, which is the more structured method for continuous monitoring.

Question 8

Your Windows server performance has degraded significantly. You need to determine if a specific service is consuming most of the CPU time. Which tool should you use?
A. Group Policy
B. Regecit
C. Task Manager
D. Performance Monitor

Answer 8

C. Task Manager
Task Manager is the most straightforward tool for quickly identifying which processes and services are consuming the most CPU time. It provides real-time data on CPU usage, memory usage, disk activity, and more. You can access it by pressing Ctrl+Shift+Esc or by typing “Task Manager” in the search bar. Under the “Processes” tab, you can sort the processes by CPU usage to identify which service or application is consuming resources.

Question 9

Which Linux command is used to create a filesystem?
A. partprobe
B. mkfs
C. fdisk
D. mount

Answer 9

B. mkfs
The mkfs (make filesystem) command is used in Linux to create a filesystem on a storage device or partition. It prepares the partition for use by a specific filesystem type (e.g., ext4, xfs, etc.).
