This LPIC-2 practice question tests your understanding of system security. 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.
Your company runs a web application on a Linux server that uses Apache HTTPD with mod_ssl for HTTPS. Recently, after a security audit, it was discovered that the server is vulnerable to the POODLE attack on SSLv3. The server is running RHEL 8 with Apache 2.4. The SSL configuration file /etc/httpd/conf.d/ssl.conf currently has the line 'SSLProtocol all -SSLv2'. You need to disable SSLv3 and also disable all versions of TLS below 1.2, while still allowing TLS 1.2 and 1.3. The server must remain available immediately. Which action should you take?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "immediately / without restart"
Why it matters: Time or reboot constraint — the correct answer must take effect right away without requiring a reboot or reload.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Change 'SSLProtocol all -SSLv2' to 'SSLProtocol TLSv1.2 TLSv1.3'
Option C is correct. Changing 'SSLProtocol all -SSLv2' to 'SSLProtocol TLSv1.2 TLSv1.3' disables SSLv3 and older TLS versions. Option A would disable more than needed (TLSv1 and TLSv1.1 are included in 'all -SSLv2 -SSLv3'), but it doesn't explicitly allow TLS 1.2/1.3; however, 'all' includes TLS 1.2, but removing SSLv3 still allows TLS 1.0 and 1.1? Actually 'all' includes TLS 1.0,1.1,1.2, so 'all -SSLv2 -SSLv3' would allow TLS 1.0 and 1.1, which are too old. Option B only adds -SSLv3 but does not disable TLS 1.0/1.1. Option D removes SSLv2 and SSLv3 but still allows TLS 1.0/1.1 via 'all'. Only option C explicitly sets only the desired protocols.
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.
✗
Change 'SSLProtocol all -SSLv2' to 'SSLProtocol all -SSLv2 -SSLv3'
Why it's wrong here
This disables SSLv3 but still allows TLS 1.0 and 1.1, which are deprecated.
✗
Add 'SSLProtocol -SSLv3' after the existing line
Why it's wrong here
The second line would override? Actually Apache uses last occurrence, but this might cause conflicts; still allows TLS 1.0/1.1.
✓
Change 'SSLProtocol all -SSLv2' to 'SSLProtocol TLSv1.2 TLSv1.3'
Why this is correct
This explicitly enables only TLS 1.2 and 1.3, disabling all older protocols.
Clue confirmation
The clue word "immediately / without restart" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
Change the line to 'SSLProtocol TLSv1.2 TLSv1.3 -SSLv2 -SSLv3'
Why it's wrong here
Redundant: the minus options are unnecessary if you explicitly list the allowed protocols. This would still work but is not standard.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→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 LPIC-2 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.

What is the correct answer to this question?
The correct answer is: Change 'SSLProtocol all -SSLv2' to 'SSLProtocol TLSv1.2 TLSv1.3' — Option C is correct. Changing 'SSLProtocol all -SSLv2' to 'SSLProtocol TLSv1.2 TLSv1.3' disables SSLv3 and older TLS versions. Option A would disable more than needed (TLSv1 and TLSv1.1 are included in 'all -SSLv2 -SSLv3'), but it doesn't explicitly allow TLS 1.2/1.3; however, 'all' includes TLS 1.2, but removing SSLv3 still allows TLS 1.0 and 1.1? Actually 'all' includes TLS 1.0,1.1,1.2, so 'all -SSLv2 -SSLv3' would allow TLS 1.0 and 1.1, which are too old. Option B only adds -SSLv3 but does not disable TLS 1.0/1.1. Option D removes SSLv2 and SSLv3 but still allows TLS 1.0/1.1 via 'all'. Only option C explicitly sets only the desired protocols.
