The Seven Domains at a Glance
The published Exam 201 objective headings are listed below. LPI assigns weights to individual objectives rather than to whole domains, so do not trust any source quoting a neat percentage per domain. For a fuller walkthrough, see LPIC-2 201-450 Exam Domains: Complete Guide to All 7 Content Areas.
- Capacity Planning
- Linux Kernel
- System Startup
- Filesystem and Devices
- Advanced Storage Device Administration
- Networking Configuration
- System Maintenance
Notice the shape of the list: it moves from measuring a running system, to building and loading the kernel, to booting, to storage, to networking, and finally to maintaining software. That sequence is also a sensible order for review.
Capacity Planning and Linux Kernel Quick Reference
Domain 1: Capacity Planning
You are expected to measure, interpret and forecast resource usage on a Linux system, then act on what you find.
- Know the standard monitoring tools by purpose:
top,htop,vmstat,iostat,sar,mpstat,free,uptime. - Be able to read load average values and relate them to CPU count.
- Distinguish CPU-bound, memory-bound, I/O-bound and network-bound symptoms from tool output.
- Understand that
sardata collection relies on the sysstat package and its collected history files. - Know basic trend and forecasting concepts: collecting baseline data over time to predict when resources run out.
Domain 2: Linux Kernel
This domain is heavily command-and-path driven, which makes it a favorite for fill-in-the-blank items.
- Module handling:
lsmod,modinfo,modprobe,insmod,rmmod,depmod. - Know where module configuration lives:
/etc/modprobe.d/and the module tree under/lib/modules/. - Runtime kernel parameters:
sysctl,/proc/sys/, and persistent settings in/etc/sysctl.confor/etc/sysctl.d/. - Kernel compilation workflow: obtain source, configure (
make menuconfigand relatives), build, install modules, install the kernel, update the boot loader. - Identify hardware and kernel state with
uname,lspci,lsusb,dmesg, andudevadm. - Understand how udev rules in
/etc/udev/rules.d/influence device naming and behavior.
sysctl is the command and /etc/sysctl.conf is the persistence file, and that modprobe is the command while /etc/modprobe.d/ holds its configuration.System Startup Quick Reference
Domain 3: System Startup
Expect questions about the sequence from firmware to a usable login, and about repairing a system that will not boot.
- Boot order concept: firmware, boot loader, kernel with initial ramdisk, then init system.
- GRUB 2 essentials:
/etc/default/grubfor settings,grub-mkconfig(orgrub2-mkconfig) to regenerate, andgrub-installto place the loader. - Know the generated configuration file is not meant to be edited by hand.
- Recovery: using the boot loader edit prompt, rescue or single-user targets, and a live medium with
chroot. - systemd concepts: units, targets,
systemctl,journalctl,systemctl set-default, andsystemctl isolate. - Also be aware of legacy SysV runlevels and how they map conceptually to systemd targets.
- Understand the role of the initial RAM filesystem and tools that build it.
When reviewing this domain, practice writing the exact recovery sequence from memory: boot to a rescue environment, mount the root filesystem, chroot, fix the configuration, regenerate the loader configuration, reinstall if needed, exit and reboot. Candidates who can narrate that chain handle scenario questions well. Our LPIC-2 201-450 Study Guide shows where this fits into a full preparation plan.
Filesystems, Devices and Advanced Storage
Domain 4: Filesystem and Devices
This domain covers creating, mounting, checking and tuning filesystems.
- Mount management:
mount,umount,/etc/fstabfield order (device, mount point, type, options, dump, pass). - Identify devices persistently using UUID or label (
blkid,lsblk) instead of raw device names. - Filesystem tools:
mkfsvariants,fsck,e2fsck,tune2fs,dumpe2fs,resize2fs. - Know the main filesystems candidates meet: ext2/3/4, XFS, Btrfs, and the basic differences in their administration tools.
- Automounting concepts with
autofsand systemd mount or automount units. - Encrypted filesystems with LUKS via
cryptsetup. - Swap handling:
mkswap,swapon,swapoff.
Domain 5: Advanced Storage Device Administration
Here the exam moves to layered and networked storage.
- Software RAID with
mdadm: creating arrays, checking status through/proc/mdstat, adding and replacing failed members. - Know the common RAID levels and what each trades off in redundancy and capacity.
- LVM layering: physical volumes, volume groups, logical volumes, and the matching
pv*,vg*,lv*commands; know how to extend a volume and then grow the filesystem. - LVM snapshots and their purpose.
- Disk tuning and inspection:
hdparm,smartctlfor health data, and I/O scheduler concepts. - Network block and file storage concepts, including iSCSI initiator and target roles.
Networking Configuration Commands
Domain 6: Networking Configuration
Know both the modern and the legacy toolsets, because the objectives expect awareness of each.
- Interface and address management with
ip(ip addr,ip link,ip route) alongside olderifconfigandroutehabits. - Persistent configuration varies by distribution, so know that the files and managers differ and that NetworkManager and systemd-networkd exist as options.
- Routing and forwarding: static routes, default gateway, and enabling IP forwarding through a kernel parameter.
- Name resolution:
/etc/hosts,/etc/resolv.conf,/etc/nsswitch.conf. - Troubleshooting toolkit:
ping,traceroute,ss,netstat,tcpdump,nmap,dig. - Wireless and virtual interfaces, bonding and bridging concepts, and VPN awareness.
- Packet filtering basics and how rules relate to traffic flow.
A reliable review habit: for every symptom ("host reachable by IP but not by name"), write which layer is broken and which one command proves it. That mental map is more useful than memorizing syntax in isolation.
System Maintenance Essentials
Domain 7: System Maintenance
This domain addresses keeping a system current and recoverable.
- Building software from source: the configure, make, make install workflow and where installed files land.
- Package management on both major families: RPM-based tools (
rpm,yumordnf) and Debian-based tools (dpkg,apt). - Querying and verifying packages: which package owns a file, what files a package installed, and how to verify integrity.
- Backup and restore strategy: full versus incremental concepts, plus tools such as
tar,rsync,dd, andcpio. - Notifying users of maintenance events using login messages and broadcast tools.
Because this domain is practical, the best review is hands-on: install a package, query its files, remove it, then rebuild a small program from source and see where it ends up. If you are weighing how much effort the whole exam demands, How Hard Is the LPIC-2 201-450 Exam? gives an honest picture.
Reading the Question Style
The format mixes multiple-choice with fill-in-the-blank, and the fill-in-the-blank items are what separate casual users from administrators. Typical patterns include:
- Complete the command: supply the missing utility name or option from a described task.
- Name the file: identify the configuration file or directory that controls a behavior.
- Order the steps: choose the correct sequence for a procedure such as extending a logical volume.
- Interpret the output: read a snippet from
vmstat,/proc/mdstatorfstaband decide what it means.
Key Takeaway
With 60 questions in 90 minutes you have roughly a minute and a half each. Answer the fill-in-the-blank items you know cold first, flag the long scenario items, and return to them. Typed answers must be exact, so practice spelling commands and paths, not just recognizing them.
Since these are not official exam questions in any practice setting, treat any third-party material as objective-mapped practice only. You can drill the objective areas using the practice tests at the LPIC-2 201-450 Exam Prep practice site, which are independently authored and not issuer questions.
Scheduling the Domains
If you only follow one structure, tie the order to dependencies: later domains assume earlier ones. Here is a compact eight-week arrangement built around the domains themselves.
Capacity Planning
- Run each monitoring tool on a busy lab machine and interpret the output.
- Set up sysstat and read collected history.
Linux Kernel
- Load, inspect and blacklist modules; persist a sysctl change.
- Walk through a kernel build configuration.
System Startup
- Regenerate GRUB configuration and practice a chroot recovery.
- Change default targets and read the journal.
Filesystem and Devices, then Advanced Storage
- Build and resize filesystems, edit fstab, set up LUKS.
- Create RAID and LVM, simulate a disk failure, extend a volume.
Networking Configuration
- Configure routes, forwarding and name resolution; diagnose broken lab scenarios.
System Maintenance
- Compile from source, query packages on both families, run backup and restore drills.
Review and timed practice
- Take timed sets in the 60-question, 90-minute format and revisit weak objectives.
Storage gets two weeks because it combines the most commands and the highest risk of order-of-operations mistakes. Adjust to your own background: someone who administers networks daily can compress Week 6 and spend it on RAID and LVM instead.
Frequently Asked Questions
