In this lesson
Prepare for the Linux+ XK0-006 exam (CompTIA Linux+ V8). In this lesson: archives and compression (tar, cpio, gzip, bzip2, xz), copy and read tools (rsync, dd, ddrescue), QEMU and KVM, disk images with qemu-img, VM states and operations with virsh, templates, cloning, migration, and virtual network types, with Pinecrest Media, a fictional video streaming company, as the running example. Includes three original practice questions.
Preview the topics
- A disk in an old archive server is failing, and reads of some areas return errors. The team wants to copy as much data as possible to an image file before the disk dies. Which tool fits?
- A partner sends a virtual disk in VMDK format, and Pinecrest wants to run it on KVM, in the qcow2 format, with snapshots. Which command prepares the image?
- New encoding machines must be reachable from the office network, with addresses on the same subnet as the physical servers. Which virtual network type fits?
