- A
rsyslog reads log messages directly from the journal files in /var/log/journal.
Why wrong: rsyslog does not read journal files; it receives messages via socket or from journald forwarding.
- B
The command 'journalctl --list-boots' lists only the current boot's journal entries.
Why wrong: --list-boots lists all boots for which journal data is available, not just the current.
- C
The command 'journalctl -u sshd.service' outputs the same as 'tail -f /var/log/messages' for SSH logs.
Why wrong: /var/log/messages is a text file; journalctl outputs from the binary journal, and they may not be identical.
- D
The journal stores logs in a structured binary format, allowing filtering by fields like _UID or _SYSTEMD_UNIT.
journald uses structured logging with various metadata fields.
- E
The journal can forward log messages to rsyslog by setting ForwardToSyslog=yes in /etc/systemd/journald.conf.
This configuration enables forwarding from journald to syslog.
Quick Answer
The correct answer is that the systemd journal stores log data in a structured binary format, enabling precise field-based filtering via journalctl, while rsyslog uses plain-text log files. This distinction matters because the journal’s binary format supports queries by specific fields like _UID or _SYSTEMD_UNIT, offering far more granularity than rsyslog’s traditional text-based logs. On the Red Hat Certified System Administrator EX200 exam, this concept tests your understanding of modern log management in RHEL 8 and 9, often appearing in questions about log forwarding or troubleshooting. A common trap is assuming both tools store logs identically; remember that rsyslog is for text-based syslog messages, while the journal is a binary database. To forward logs from the journal to rsyslog, you set ForwardToSyslog=yes in /etc/systemd/journald.conf. Memory tip: “Binary journal for field queries, text rsyslog for legacy syslog.”
EX200 Operate running systems Practice Question
This EX200 practice question tests your understanding of operate running systems. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which TWO statements about systemd journal and rsyslog are correct?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
The journal stores logs in a structured binary format, allowing filtering by fields like _UID or _SYSTEMD_UNIT.
Option D is correct because the systemd journal stores log data in a structured binary format (using the journald protocol), which allows filtering by specific fields such as _UID, _SYSTEMD_UNIT, or _COMM. This enables precise queries via journalctl, unlike plain-text log files.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
rsyslog reads log messages directly from the journal files in /var/log/journal.
Why it's wrong here
rsyslog does not read journal files; it receives messages via socket or from journald forwarding.
- ✗
The command 'journalctl --list-boots' lists only the current boot's journal entries.
Why it's wrong here
--list-boots lists all boots for which journal data is available, not just the current.
- ✗
The command 'journalctl -u sshd.service' outputs the same as 'tail -f /var/log/messages' for SSH logs.
Why it's wrong here
/var/log/messages is a text file; journalctl outputs from the binary journal, and they may not be identical.
- ✓
The journal stores logs in a structured binary format, allowing filtering by fields like _UID or _SYSTEMD_UNIT.
Why this is correct
journald uses structured logging with various metadata fields.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse the journal's structured binary format with plain-text log files, or assume rsyslog reads journal files directly, when in fact forwarding is configured via journald.conf.
Trap categories for this question
Command / output trap
/var/log/messages is a text file; journalctl outputs from the binary journal, and they may not be identical.
Detailed technical explanation
How to think about this question
The systemd journal uses a binary format with indexed fields, enabling efficient filtering and metadata storage (e.g., priority, facility, boot ID). The ForwardToSyslog directive in /etc/systemd/journald.conf controls whether journal messages are sent to the traditional syslog socket, allowing rsyslog to process them. In real-world scenarios, administrators often use journalctl with field filters (e.g., _UID=1000) to isolate user-specific logs without parsing text files.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the EX200 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
