- LPIC-2 202-450 is Exam 202 (Part 2 of 2), version 4.5, issued by the Linux Professional Institute (LPI).
- The paper has 60 multiple-choice and fill-in-the-blank questions with a 90-minute time limit.
- Passing 202-450 alone does not award LPIC-2; you must also pass 201-450 and hold an active LPIC-1.
- Six objective areas: DNS, Web Services, File Sharing, Network Client Management, E-Mail Services, and System Security.
What the LPIC-2 202-450 Actually Is
The LPIC-2 202-450 is the second of two required exams for the Linux Professional Institute's LPIC-2 certification, the "Linux Engineer" tier in LPI's three-level professional track. Its full title is LPIC-2 Exam 202 (Part 2 of 2), version 4.5, and the exam code 202-450 identifies the objectives revision it tests. The authoritative source for what is covered is LPI's published objectives page for Exams 201 and 202 (version 4.5).
If you have searched the exam code and found unrelated material, that is because the same string appears in other contexts. This article covers only the LPI exam. Exam 202 is the network-services half of LPIC-2: where its sibling, Exam 201, focuses on the Linux kernel, system startup, filesystems, storage, and capacity planning, Exam 202 concentrates on the services a Linux administrator runs for a network and how to secure them.
For adjacent explanations of the naming, see our pages on what LPIC-2 202-450 stands for and the meaning of the exam code.
Where Exam 202 Fits in the LPIC-2 Path
LPIC-2 is not awarded for passing a single paper. Three conditions must all be satisfied:
- An active LPIC-1 certification.
- A pass on Exam 201 (201-450).
- A pass on Exam 202 (202-450).
Because the two exams are independent papers, a candidate who passes one and fails the other does not lose the pass. That makes Exam 202 a sensible first target if your daily work involves DNS, web servers, Samba, mail, or firewalls, since your hands-on experience carries more weight there than it would on kernel-compilation questions.
Exam Format and Question Style
Each LPIC-2 paper, including 202-450, consists of 60 questions delivered within 90 minutes. Two item types appear:
- Multiple-choice questions, including single-answer and multiple-answer variants where you must select every correct option.
- Fill-in-the-blank questions, where you type a command, option, filename, or directive from memory.
The fill-in-the-blank format is what separates LPI exams from many vendor-neutral competitors. You cannot eliminate wrong options by inspection; you need to recall the exact syntax. Expect prompts such as supplying the directive that limits zone transfers, the Postfix command that lists the mail queue, or the option that makes an NFS export read-only. At 90 minutes for 60 items, you have roughly a minute and a half per question, which is generous for recall items but tight for questions that present a configuration excerpt and ask you to find the fault.
The Six Objective Areas in Detail
LPI publishes Exam 202 as six headings, each containing individual objectives. LPI weights the individual objectives rather than publishing a single percentage per heading, so we do not assert aggregate domain weights. For a deeper walk-through, see the complete guide to all six content areas. Here is what each demands in practice.
Domain 1: Domain Name Server
This is DNS administration with BIND at the center, plus the security hardening around it.
- Authoritative zone configuration: zone files, record types, and reverse zones
- Caching and forwarding resolver setups
- Securing a DNS server: restricting queries and transfers, running in a chroot or as an unprivileged user, and using TSIG for signed transactions
- DNSSEC concepts and the operational steps they imply
- Diagnostic tools such as
dig,named-checkconf, andnamed-checkzone
Domain 2: Web Services
Apache HTTPD and Nginx configuration, with attention to both function and security.
- Virtual hosts, both name-based and IP-based
- SSL/TLS configuration, certificates, and client authentication
- Apache modules, access control, and URL rewriting
- Nginx as a web server and reverse proxy
- Squid as a caching proxy, including ACL logic
Domain 3: File Sharing
Moving files between Linux and other systems.
- Samba server configuration: shares, global settings, user mapping, and the roles Samba can play in a Windows-oriented network
- Samba diagnostics, including checking configuration syntax and listing shares
- NFS exports, export options, mounting, and security-related options
Domain 4: Network Client Management
Services that configure and authenticate clients on the network.
- DHCP server configuration: scopes, leases, static reservations, and relay behavior
- PAM modules and stack configuration for authentication
- LDAP client usage and directory concepts, including search filters and entries
- OpenLDAP server basics
Domain 5: E-Mail Services
Running a mail system end to end.
- Postfix configuration: main parameters, relaying, restrictions, and queue management
- Local delivery and mail aliases
- Remote mailbox access through IMAP and POP servers such as Dovecot
- Sieve filtering of incoming mail
Domain 6: System Security
Hardening a Linux host and its network exposure.
- Firewalling with packet filtering and NAT rules
- OpenSSH server and client hardening, including key-based authentication
- Intrusion detection tooling and security assessment utilities
- VPN concepts, including OpenVPN
- Operating-system-level security practices
One pattern to notice: Domains 1, 2, 3, and 5 are each anchored on a specific daemon, so memorizing that daemon's configuration structure pays off directly. Domains 4 and 6 are broader and reward conceptual understanding of how components interact.
Who Benefits From This Credential
The skills in 202-450 map to roles where Linux machines provide infrastructure services rather than just running applications:
- Linux systems administrators responsible for DNS, DHCP, mail, and file servers in small and mid-sized organizations
- Network and infrastructure engineers who maintain edge services such as proxies, VPN gateways, and firewalls
- Hosting and managed-service staff who configure web and mail stacks for many tenants
- Security-minded administrators who harden SSH, firewall rules, and service exposure
Employers rarely list "LPIC-2 202-450" by exam code; they ask for LPIC-2 or equivalent Linux engineering experience.

Registration, Validity, and What Is Not Fixed
LPI exams are delivered through Pearson VUE, which offers testing-center and online-proctored delivery in many regions. You create an LPI account, receive an LPI ID, and book the exam through the delivery partner. Several details are deliberately not hard-coded in this article because they vary:
| Item | What we can state |
|---|---|
| Questions | 60 multiple-choice and fill-in-the-blank |
| Time limit | 90 minutes |
| Certification validity | 5 years; verify current renewal options with LPI |
| Exam fee | Varies by region; confirm with LPI or Pearson VUE |
| Passing score | Not stated here; confirm directly with LPI |
| Pass rate | No verified official figure, so none is asserted |
For budgeting guidance and how to think about retake and renewal costs, see the certification cost breakdown. For booking logistics, see exam dates and scheduling. Note that we deliberately avoid quoting a pass rate; our pass rate page explains why published unofficial numbers should be treated cautiously.
Sequencing Your Preparation Around the Six Areas
The only study-method advice worth giving here is about order. The six areas are not equally independent: several build on shared networking knowledge, and a few create natural dependencies.
DNS first
- Many other services assume working name resolution, so a solid grasp of BIND zones and security pays off everywhere
- Practice with
diguntil reading its output is automatic
Web Services and File Sharing
- Build an Apache virtual host with TLS, then an Nginx reverse proxy in front of it
- Stand up a Samba share and an NFS export, then deliberately misconfigure each and diagnose it
Network Client Management and E-Mail
- DHCP, PAM, and LDAP interlock, so study them together
- Build a Postfix and Dovecot pair and trace a message through the queue
System Security and review
- Apply firewall rules and SSH hardening to the machines you built in earlier blocks
- Close with timed mixed practice to simulate the 60-question, 90-minute pace
Building the services yourself in a lab is the single most reliable way to handle the fill-in-the-blank items, because typing real configurations builds the recall the exam rewards. Our full study guide expands this plan, and the cheat sheet condenses the commands and directives worth memorizing. When you want exam-style repetition, the LPIC-2 202-450 practice tests are independently authored and mapped to the published objectives; they are original practice material, not actual LPI questions or an official exam simulation.
Key Takeaway
Treat 202-450 as six hands-on service families, not a theory exam. Candidates who have actually configured BIND, Apache, Samba, Postfix, DHCP, and a firewall find the fill-in-the-blank items far easier than those who only read about them.
If you are still deciding whether to pursue the credential or want more background, our overview pages on LPIC-2 202-450 certification and training options cover the broader context. To test your readiness against the objectives, you can start with a practice test and see which of the six areas needs work first.
Frequently Asked Questions
No. LPIC-2 requires passing both 201-450 and 202-450 while holding an active LPIC-1. Passing 202-450 alone completes only half of the requirement.
The paper contains 60 multiple-choice and fill-in-the-blank questions, with a 90-minute time limit. Fill-in-the-blank items require you to type exact commands or directives.
Six areas: Domain Name Server, Web Services, File Sharing, Network Client Management, E-Mail Services, and System Security. LPI weights individual objectives rather than publishing a percentage per heading.
Yes. The two papers are independent, so you may take them in either order. Many candidates start with whichever aligns with their current job, but you still need both passes and an active LPIC-1 for LPIC-2.
LPI certifications are valid for 5 years. Renewal options and regional pricing can change, so confirm the current details with LPI or Pearson VUE before planning.
