- LPIC-2 202-450 is the second of two required exams for LPIC-2; passing it alone does not award the certification.
- The paper contains 60 multiple-choice and fill-in-the-blank questions with a 90-minute time limit.
- Exam 202 covers six areas: DNS, web services, file sharing, network client management, e-mail, and system security.
- An active LPIC-1 certification is required before LPI will award LPIC-2.
What LPIC-2 202-450 Actually Is
LPIC-2 202-450 is the second exam in the Linux Professional Institute's advanced-level certification track. Its full title is LPIC-2 Exam 202 (Part 2 of 2), version 4.5. The "450" in the exam code identifies the 4.5 objectives revision published by LPI, and the "202" identifies it as the second of the two papers that together make up LPIC-2.
Where Exam 201 concentrates on the Linux system itself (kernel, boot process, storage, and general system administration), Exam 202 turns outward to the network. It tests whether you can build, configure, and secure the services a Linux server provides to other machines: name resolution, web serving, file sharing, client network configuration, mail delivery, and the security controls that wrap around all of it.
If you are looking for the broader definition of the credential, the companion article on the LPIC-2 202-450 certification covers the credential at a higher level. This article focuses on what the Exam 202 paper itself is and what it demands from you.
How Exam 202 Fits Into the LPIC-2 Certification
The single most common misunderstanding about this exam is that passing it earns you a credential. It does not, at least not by itself. LPIC-2 is awarded only when you hold an active LPIC-1 certification and have passed both exams in the LPIC-2 series: 201-450 and 202-450.
Because the two papers are separate sittings, you can treat them as two focused projects instead of one enormous one. Candidates who administer production servers often find the services-heavy 202 material closer to their daily work and take it first. For a full breakdown of eligibility rules, see the LPIC-2 202-450 requirements guide.
Exam Format and Question Style
Exam 202 consists of 60 questions delivered in 90 minutes. That works out to roughly a minute and a half per question, which is comfortable for recognition-style items but tight if you stall on configuration syntax you have not practiced.
The question types are:
- Multiple-choice (single answer): pick the one correct option from a list.
- Multiple-choice (multiple answers): select all correct options, where partial knowledge is penalized.
- Fill-in-the-blank: type a short answer such as a command name, a configuration directive, or a file path.
The fill-in-the-blank format is what separates LPI exams from many other IT certifications. There is no list of options to jog your memory. If a question asks which directive restricts a Samba share to a set of users, or which command reloads zone data in BIND, you have to produce the term yourself. That makes hands-on repetition far more valuable than reading.
The Six Content Areas, Explained
LPI publishes Exam 202 as six topic headings. Weights are assigned to individual objectives within them rather than to the headings as a whole, so you should not budget study time by assuming equal or fixed percentages per area. For the objective-level view, see the complete guide to the six content areas. Here is what each area asks of you.
Domain 1: Domain Name Server
You must be able to configure and operate authoritative and caching DNS using BIND, and understand how to secure it.
- Writing and validating zone files, including forward and reverse zones
- Record types and their purposes (A, AAAA, MX, NS, CNAME, PTR, SOA, TXT)
- Master and slave relationships and zone transfers
- Running a caching or forwarding resolver
- Securing a DNS server, including chroot operation, restricting transfers, and DNSSEC concepts
Domain 2: Web Services
This area covers serving web content and proxying it, with Apache as the centerpiece.
- Apache configuration: modules, virtual hosts, and per-directory control
- HTTPS with SSL/TLS certificates and the related directives
- Access control and authentication for web content
- Squid as a caching and access-controlling proxy
- Nginx as a web server and reverse proxy
Domain 3: File Sharing
Here you demonstrate that Linux can serve files to both Windows and Unix-style clients.
- Samba server configuration, share definitions, and user mapping
- Samba's role in domain environments
- NFS exports, mount options, and access restrictions
- Diagnosing permission and name-mapping problems between clients and servers
Domain 4: Network Client Management
This area is about the services that configure and authenticate clients on a network.
- DHCP server configuration, scopes, and static reservations
- PAM configuration and its role in authentication
- LDAP client usage and directory concepts
- Configuring a Linux system to authenticate against central services
Domain 5: E-Mail Services
Running mail is notoriously detail-heavy, and the exam reflects that.
- Postfix configuration, including main.cf parameters and queue management
- Managing mail aliases and local delivery
- Sieve-based mail filtering
- Dovecot for IMAP and POP3 access
- Understanding how SMTP relays, sender restrictions, and mail routing fit together
Domain 6: System Security
The final area ties everything together with hardening and protection of exposed services.
- Firewalling and packet filtering on a Linux host
- Securing remote access with OpenSSH, including key-based authentication
- Intrusion detection and network monitoring tools
- OpenVPN for encrypted tunnels
- Reducing the attack surface of the services configured in the other five areas
Who Should Take It and Who Hires for It
This exam suits people whose work involves running Linux servers that other people and systems depend on. Typical job titles associated with LPIC-2 level skills include Linux systems administrator, network or infrastructure administrator, DevOps and platform engineers who manage their own service stacks, and hosting or managed-services engineers. Employers who run mixed fleets of web servers, mail servers, and internal infrastructure tend to value a credential that proves you can do all of it, not just one slice.
Because Exam 202 is explicitly service-oriented, the knowledge maps directly onto tasks like standing up a mail relay, delegating a DNS zone, or exposing a Samba share to a Windows department. That practicality is the credential's main selling point to hiring managers. For a view of the kinds of roles that ask for it, see the LPIC-2 202-450 jobs article, and if you are weighing the credential's value, the ROI analysis and salary guide go deeper.
Key Takeaway
The exam rewards people who have actually configured these services. If you have never run BIND, Postfix, or Samba outside a lab guide, plan extra hands-on time before booking, because the fill-in-the-blank questions expose memorization without practice.
Registration, Fees, and Validity Mechanics
LPI exams are delivered through Pearson VUE, where you create or use an existing LPI candidate ID, choose the exam, and schedule either at a testing center or, where offered, through online proctoring. Because delivery options and regional pricing vary, confirm the current details with LPI and Pearson VUE at booking time rather than relying on a figure quoted elsewhere. Our certification cost breakdown and exam dates and scheduling guide explain how to plan around this.
Two facts are worth stating plainly:
- Validity: LPIC-2 certification is valid for 5 years. Check LPI for current renewal options, since those policies can change.
- Prerequisite: An active LPIC-1 is required to receive LPIC-2, even though you can sit Exam 202 itself in the way that suits your schedule.
A Domain-Ordered Prep Sequence
Rather than treating all six areas as interchangeable, sequence them by dependency. DNS underpins almost everything else, so it comes first. Mail and web services both rely on name resolution, and security is easiest to study last because it wraps the services you have already built. Here is one ordering that follows those dependencies:
Domain Name Server
- Build a master and slave BIND pair in a lab
- Practice forward and reverse zone files until you can write them from memory
Web Services
- Configure Apache virtual hosts with HTTPS
- Stand up a Squid proxy and an Nginx reverse proxy
File Sharing and Network Client Management
- Share a directory via Samba and NFS to different clients
- Configure DHCP, PAM, and LDAP client authentication
E-Mail Services
- Deploy Postfix with Dovecot and test local and remote delivery
- Write a Sieve filter and verify it
System Security and Review
- Harden SSH, set up OpenVPN, and review firewall rules
- Take timed practice sets against the objectives
Adjust the pacing to your own background. Someone who already manages mail servers daily can compress Week 4 and spend the time on file sharing instead. For a fuller plan, the LPIC-2 202-450 study guide and the quick-reference cheat sheet are good companions, and structured options are covered under training.

Frequently Asked Questions
No. LPIC-2 requires passing both 201-450 and 202-450, and you must hold an active LPIC-1. Passing Exam 202 alone does not award the certification.
The paper has 60 multiple-choice and fill-in-the-blank questions with a 90-minute time limit. The fill-in-the-blank items require you to type exact commands, directives, or file names.
It covers six areas: Domain Name Server, Web Services, File Sharing, Network Client Management, E-Mail Services, and System Security. LPI weights individual objectives rather than whole areas, so see the domains guide for the objective-level breakdown.
Difficulty depends heavily on your hands-on experience with BIND, Apache, Samba, and Postfix. Candidates who have only read about these tools tend to struggle most with the fill-in-the-blank items. See our difficulty guide and pass rate discussion for what can and cannot be said about the numbers.
LPIC-2 certification is valid for 5 years. Verify current renewal options and any regional pricing or delivery details with LPI and Pearson VUE before you plan your timeline.
