How to Set a Tuned Performance Profile for Database Workloads
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.
An administrator needs to configure system tuning profiles for a database server. Which command is used to set the 'throughput-performance' profile?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue:
"which command"Why it matters: Tests specific CLI syntax. Recall the exact command and its required context — near-synonyms and partial matches are common distractors.
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
✓
tuned-adm profile throughput-performance
The `tuned-adm profile throughput-performance` command is correct because Tuned is the system tuning service on Red Hat Enterprise Linux, and `tuned-adm` is the command-line tool used to activate predefined tuning profiles. The 'throughput-performance' profile optimizes the system for maximum network and disk throughput by disabling power-saving features and tuning kernel parameters.
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.
- ✗
powertop --set-profile=throughput-performance
Why it's wrong here
powertop is for power tuning, not general throughput.
- ✗
sysctl -w kernel.throughput=1
Why it's wrong here
sysctl sets individual kernel parameters but not a predefined profile.
- ✗
systemctl set-profile throughput-performance
Why it's wrong here
systemctl does not manage tuning profiles.
- ✓
tuned-adm profile throughput-performance
Why this is correct
tuned-adm is the correct tool for applying tuning profiles.
Clue confirmation

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse `systemctl` (which manages systemd services) with `tuned-adm` (which manages Tuned profiles), or they assume a generic sysctl parameter exists for setting a complete tuning profile.
Detailed technical explanation
How to think about this question
Tuned profiles are defined in `/etc/tuned/` and consist of shell scripts and configuration files that adjust sysctl parameters, kernel boot options, and device power management settings. The 'throughput-performance' profile, for example, sets `kernel.sched_min_granularity_ns` to 10,000,000 and `vm.dirty_ratio` to 40, favoring I/O throughput over latency. In a real-world scenario, a database server handling large sequential writes would benefit from this profile to maximize disk write throughput, but it may increase latency for small random queries.
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.

Same concept, more angles
1 more ways this is tested on EX200
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. An administrator wants to optimize system performance for a database workload. Which tool should be used to select a performance profile?
medium- A.performance-tune --profile database
- B.setroubleshoot
- ✓ C.tuned-adm profile throughput-performance
- D.systemctl set-profile database
Why C: C is correct because `tuned-adm profile throughput-performance` selects a Tuned performance profile optimized for high throughput, which is suitable for database workloads that benefit from increased I/O and network performance. Tuned is the systemd-based dynamic system tuning daemon in RHEL that adjusts kernel parameters, disk schedulers, and other settings based on the selected profile.
