How should I use these System Architecture practice questions?

Read each scenario carefully and choose your answer before revealing the explanation. Then check why your choice was right or wrong. Repeat until the reasoning feels automatic.

Can I practise just System Architecture questions in a focused session?

Yes — use the session launcher on this page to start a 10-, 20-, 30- or 50-question session drawn entirely from the System Architecture domain.

System Architecture practice questions

Use this page to practise System Architecture questions for this certification. Focus on how the exam tests system architecture in scenario format — understanding the why behind each answer builds more durable knowledge than memorising options.

Courseiva uses original exam-style practice questions designed for learning and revision. The goal is to understand the concepts, recognise exam patterns, and improve through explanations — not memorise copied exam dumps.

What the exam tests

What to know about System Architecture

System Architecture questions on this certification test your ability to deploy and manage system architecture concepts in scenario-based situations.

Core System Architecture concepts and how they apply in real-world cloud scenarios.

How to deploy system architecture correctly and verify the outcome.

Troubleshooting system architecture issues by interpreting error output and system state.

Cloud best practices and System Architecture design trade-offs tested by this certification.

Watch out for

Common System Architecture exam traps

▸Selecting the most expensive service when a simpler managed option meets the requirement.
▸Forgetting that cloud resources must be explicitly secured — defaults are rarely secure.
▸Choosing a global service fix when the issue is region-specific.
▸Overlooking cost implications of cross-region data transfer in architecture questions.

Which command shows the amount of free and used memory in the system, including swap?

Trap 1: top

While `top` displays real-time process activity and includes a memory summary line showing total, used, free, and swap figures, it fails to meet the question’s requirement because it does not provide a dedicated, static snapshot of memory and swap usage on demand; instead, it continuously refreshes a dynamic process list. It is tempting because its header does show memory and swap statistics, making it seem sufficient, and it would be the correct choice if the task were to monitor live memory consumption alongside CPU usage over time.

Trap 2: df -h

df shows disk usage, not memory.

Trap 3: vmstat

vmstat shows virtual memory statistics but not in a simple free/used summary.

A
top
Why wrong: While `top` displays real-time process activity and includes a memory summary line showing total, used, free, and swap figures, it fails to meet the question’s requirement because it does not provide a dedicated, static snapshot of memory and swap usage on demand; instead, it continuously refreshes a dynamic process list. It is tempting because its header does show memory and swap statistics, making it seem sufficient, and it would be the correct choice if the task were to monitor live memory consumption alongside CPU usage over time.
B
free -h
free -h specifically shows memory usage with swap.
C
df -h
Why wrong: df shows disk usage, not memory.
D
vmstat
Why wrong: vmstat shows virtual memory statistics but not in a simple free/used summary.

Which command shows the amount of free and used memory in the system, including swap?

A system administrator needs to blacklist the kernel module 'pcspkr' to disable the PC speaker. Which is the correct method?

A system administrator notices that the server's clock is consistently off by several minutes. Which service should be used to synchronize the time with an external time source?

During boot, the kernel must mount the root filesystem. Which of the following is responsible for providing the kernel with the location of the root filesystem?

A server has two disk drives: /dev/sda (SSD) and /dev/sdb (HDD). The administrator wants to place frequently accessed files on the SSD for performance. Which approach best achieves this using Linux filesystem features?

A technician is troubleshooting a system that fails to boot with the error 'Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)'. What is the most likely cause?

An administrator needs to ensure that a specific kernel module is loaded automatically at boot. Which file should be used to permanently load the module?

Which command displays information about the CPU, including model name, cache size, and flags?

A server with a udev rule fails to consistently assign a persistent network interface name. What is the most likely cause?

Which TWO of the following are valid methods to reduce boot time on a Linux system? (Select exactly 2.)

Exhibit

Refer to the exhibit. How many SATA controllers are detected, and what is the connection speed of the SSD?

Exhibit
