- A
Remove the unused packages and disable the unnecessary services and ports.
Removing unused packages and disabling unneeded services directly reduces the server attack surface. Fewer active services means fewer listening ports, fewer vulnerabilities, and fewer opportunities for misuse. This is the most immediate hardening step when a server contains features that are not required for its role.
- B
Document the approved build and enforce it with configuration management or drift detection.
A documented baseline gives the team a known-good target, and configuration management or drift detection helps keep the host aligned with that target over time. This addresses the root problem of settings being re-enabled during maintenance. It also creates a repeatable process for auditing and restoring the hardened state.
- C
Allow administrators to enable any service they need without approval during maintenance windows.
Why wrong: Unrestricted changes during maintenance windows encourage configuration drift and make it difficult to prove the host still matches the approved baseline. Temporary convenience can become permanent exposure if changes are not tracked and reversed. Controlled change management is safer than informal administrator discretion.
- D
Keep the default installation profile so vendor updates are easier to apply.
Why wrong: Default installations often include unnecessary components and broader attack surfaces than the server actually needs. Ease of updating does not outweigh the risk created by unnecessary services on a database host. A hardened role-specific baseline is more appropriate than keeping general-purpose defaults.
- E
Open the firewall broadly and rely only on strong passwords.
Why wrong: Broad firewall rules weaken the boundary around the host and do not correct the unnecessary services already running. Strong passwords are important, but they do not compensate for exposed and unused management or legacy services. Hardening requires reducing both exposure and drift.
SY0-701 Security Architecture Practice Question
This SY0-701 practice question tests your understanding of security architecture. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
After a server rebuild, a Linux database host still has several unnecessary services enabled, including a graphical desktop, Telnet, and a printer service. The operations team wants a secure baseline that prevents the same drift from happening again after future maintenance. Which two actions best address the issue? Select two.
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue:
"best"Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
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
Remove the unused packages and disable the unnecessary services and ports.
Removing unused packages and disabling unnecessary services directly reduces the attack surface by eliminating potential entry points like Telnet (which transmits credentials in cleartext) and unused printer services. This aligns with the principle of least functionality, ensuring only required services run on the Linux database host.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may think removing services is sufficient without also enforcing the baseline via configuration management, or they may mistakenly believe that strong passwords alone can compensate for insecure services like Telnet.
Detailed technical explanation
How to think about this question
Configuration management tools like Ansible, Puppet, or Chef can enforce a desired state by automating package removal (e.g., `apt-get remove telnetd`) and service disabling (e.g., `systemctl disable cups`). Drift detection tools (e.g., Tripwire, Osquery) continuously compare the current system state against the approved baseline, alerting on any unauthorized changes, which is critical in regulated environments like PCI DSS where service inventory must be maintained.
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 security analyst at a medium-sized enterprise encounters this scenario during an investigation or architecture review. The correct answer reflects best practice for the specific threat or control described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Security exam questions test whether you can match controls to threats in context — not just recall definitions.
