LPIC-2 202-450 study guide
LPIC-2 202-450 · Work through your exam, one topic at a time.
LPIC-2 is the second level in the multi-level professional certification program of the Linux Professional Institute (LPI), and the 202-450 exam is one of the two exams required for it. According to LPI, LPIC-2 "will validate the candidate's ability to administer small to medium–sized mixed networks," which makes it a natural next step for administrators who already hold LPIC-1 and now manage real services rather than single hosts. The current version is 4.5, and 202-450 is paired with 201-450. The 202 exam focuses on the service side of administration: Domain Name Server, Web Services, File Sharing, Network Client Management, E-Mail Services and System Security. The LPIC-2 202-450 study guide has 6 sections and about 2,071 words.
01Domain Name Server
Domain Name Server (DNS) in LPIC-2 202-450 tests BIND 9 administration: authoritative zones, delegation, replication, query tools, and DNSSEC. You must read a named.conf, correct a zone file, and diagnose resolution without guessing.
332 words, about 2 min02Web Services
Web Services covers Apache 2.4 and nginx: virtual hosting, TLS termination, reverse proxying, logging, and safe reloads. Expect configuration repair rather than memorizing every directive.
371 words, about 2 min03File Sharing
File Sharing tests Samba and NFS: exporting directories, mapping identities, controlling access, and mounting from clients. The exam favors working configuration over broad theory.

322 words, about 2 min05E-Mail Services
E-Mail Services focuses on Postfix and Dovecot: accepting mail, routing aliases and virtual domains, queue management, TLS, and IMAP/POP3 delivery. You need to trace a message from SMTP ingress to mailbox.
343 words, about 2 min06System Security
System Security covers packet filtering, OpenSSH hardening, and cryptographic tooling. The exam expects rules that work in order, services that stay reachable, and an understanding of key trust.
