Correct answer: Press 'e' at the GRUB menu, append the parameter to the line starting with 'linux' or 'linux16', and press Ctrl+X to boot.

Pressing 'e' at the GRUB menu allows you to temporarily edit the boot entry for that specific session. Appending the parameter to the kernel line (starting with linux or linux16) and booting with Ctrl+X applies the parameter only once. Editing /etc/default/grub makes the change persistent, which violates the requirement for a temporary change.

Correct answer: True

RISC-V is a widely adopted open-standard ISA provided under open-source licenses. Unlike proprietary architectures (such as x86 or ARM), it does not require licensing fees, making it an increasingly popular choice for custom hardware and embedded Linux systems.

Correct answer: Wayland clients communicate directly with the compositor, eliminating the middleman display server present in X11, which enhances security.

In the Wayland architecture, the compositor IS the display server. Clients communicate directly with the compositor, which securely handles input and rendering. This eliminates the legacy X11 design where any application could eavesdrop on other applications' input events via the X server.

Correct answers: modprobe -r; modprobe

The 'modprobe' command is the modern standard for managing kernel modules because it automatically resolves and loads/unloads dependencies using the modules.dep file. The '-r' flag removes the module and its unused dependencies. 'rmmod' and 'insmod' do not handle dependencies automatically.

The 'modprobe' command intelligently loads the module and any prerequisites it depends on. This makes it superior to 'insmod', which requires manual dependency loading.

Correct answer: 1. pvcreate /dev/sdc 2. vgextend vg_data /dev/sdc 3. lvextend -l +100%FREE /dev/vg_data/lv_db 4. xfs_growfs /dev/vg_data/lv_db

To expand LVM storage onto a new disk: First, initialize the disk as a physical volume (pvcreate). Second, add it to the volume group (vgextend). Third, extend the logical volume to use the newly available space (lvextend). Finally, grow the XFS filesystem natively online (xfs_growfs). XFS cannot be resized with resize2fs, which is for ext-based filesystems. flowchart TD A[pvcreate /dev/sdc] --> B[vgextend vg_data /dev/sdc] B --> C[lvextend -l +100%FREE lv_db] C --> D[xfs_growfs /dev/vg_data/lv_db]

Correct answer: btrfs

Btrfs (B-Tree Filesystem) is a modern Linux filesystem designed with native support for advanced features like Copy-on-Write (CoW) snapshots, dynamic subvolumes, and built-in RAID. Ext4 and XFS are high-performance journaling filesystems but require LVM to achieve snapshot functionality.
