Free LFCA: Linux Foundation Certified IT Associate Exam Questions and Answers
Linux Foundation Certified IT Associate is one of the Linux Foundation tests covered here, sat under the code LFCA. The Linux Foundation administers these exams on behalf of different projects rather than owning one scheme — the Kubernetes credentials come from CNCF, the LFC ones from the Linux Foundation itself, and others from Hyperledger, FinOps and RISC-V. The final letter usually marks seniority, with A for associate and S or E for practitioner, and the leading letters name the technology.

Question #1
A file named fruits.txt contains six lines in this order: apple, banana, apple, cherry, banana, apple. An administrator runs the command uniq fruits.txt without any options. How many lines does the command print?
Correct answer: D
Explanation
uniq only collapses identical lines that are next to each other. In fruits.txt no line is directly followed by a copy of itself, so all six lines are printed. Running sort fruits.txt | uniq would first group the duplicates and give three lines.

Question #5
A development team deploys an application that needs a database password. Which approach BEST protects the password?

Question #7
An IT associate is deploying a customer-facing web application in the cloud. The application must stay available if a single data center in the region fails. Which design follows best practice?
Correct answer: A
Explanation
Spreading instances across availability zones removes the single data center as a point of failure, and the load balancer sends traffic only to healthy instances. Several instances in one zone still fail together, and a larger instance only adds capacity. Nightly snapshots help recovery but do not keep the application running during the failure.

Question #8
While troubleshooting a service, an IT associate wants to watch new entries appear in /var/log/messages as they are written. Which command does this?

Question #9
A company's disaster recovery plan states that, after a database server failure, no more than 15 minutes of transactions may be lost. Which disaster recovery term does this requirement describe?
Correct answer: B
Explanation
The recovery point objective is the maximum acceptable amount of data loss measured in time, and it drives how often backups or replication must occur. The recovery time objective is the maximum acceptable downtime, which is the common mix-up. The other terms describe reliability and contracted service levels.
