EX200 Deploy, configure, and maintain systems Practice Question
This EX200 practice question tests your understanding of deploy, configure, and maintain systems. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
A junior system administrator configures rsyslog on a RHEL 9 server to forward logs to a remote centralized log server. They add the line *.* @192.168.1.100:514 to /etc/rsyslog.conf and restart rsyslog with systemctl restart rsyslog. Local logging works fine, but the remote server does not receive any logs. The administrator checks the local firewall and confirms that UDP port 514 is open outbound. They also verify network connectivity using nc. What is the most likely cause?

Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The SELinux boolean rsyslog_remote is disabled, blocking outbound syslog.
Option C is correct because on RHEL 9, SELinux enforces a targeted policy that blocks rsyslog from making outbound network connections by default. The boolean `rsyslog_remote` controls this behavior; when disabled, SELinux denies the outbound syslog traffic even though the local firewall allows it. The administrator must enable this boolean with `setsebool -P rsyslog_remote on` to allow rsyslog to forward logs via UDP or TCP.
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.
✗
The systemd unit for rsyslog is masked, preventing it from running.
Why it's wrong here
The service restarted successfully, so it is not masked.
✗
The remote rsyslog server is not listening on UDP port 514.
Why it's wrong here
Possible but less likely; the administrator should check remote configuration first, but the local SELinux boolean is a common oversight.
✓
The SELinux boolean rsyslog_remote is disabled, blocking outbound syslog.
Why this is correct
SELinux blocks rsyslog from sending network traffic if boolean is off; enabling it resolves the issue.
Clue confirmation
The clue word "most likely" in the question point toward this answer.

✗
The configuration should use @@ for TCP instead of @ for UDP.
Why it's wrong here
The remote server might be configured for UDP; the admin used @ which is correct for UDP.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates focus on network-level troubleshooting (firewall, connectivity) and overlook SELinux, which is a mandatory access control layer that can block outbound connections even when the firewall is open.
Detailed technical explanation
How to think about this question
Under the hood, SELinux uses type enforcement to confine rsyslogd. The `rsyslog_remote` boolean controls the `rsyslogd_t` domain's ability to create UDP or TCP sockets to remote hosts. Even if the firewall allows outbound traffic, SELinux will deny the socket connect() call, logging an AVC denial in `/var/log/audit/audit.log`. In real-world scenarios, administrators often forget to check SELinux after verifying firewall rules, leading to silent log forwarding failures.

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 network engineer segments a warehouse floor into three subnets: 20 scanners, 5 printers, and 2 management hosts. Picking the wrong mask wastes addresses or leaves too few usable hosts. Exam questions test whether you can apply CIDR notation, calculate block size, and identify the correct usable-host range for a given prefix.
