QUESTION 1.
A district requires teachers to select a cloud-based collaboration platform for student
group projects. The primary concern is compliance with student privacy regulations
,while maintaining efficient collaboration. Which criterion should receive the highest
priority during platform selection?
A. Availability of administrative controls for user permissions, data protection, and
audit capabilities
B. Number of integrated emoji and social interaction features
C. Quantity of built-in presentation templates
D. Frequency of interface redesigns
Correct Answer: A. Availability of administrative controls for user permissions,
data protection, and audit capabilities
Explanation: Administrative controls directly support secure management of
student accounts, access permissions, and compliance with educational privacy
requirements. Templates, interface updates, and social features may improve
usability but do not adequately address the primary concern of protecting student
information.

QUESTION 2.
Students are analyzing a large environmental dataset collected over several months.
Which approach best enables them to identify seasonal trends while minimizing the
influence of daily fluctuations?
A. Displaying all values in alphabetical order
B. Applying aggregation techniques and creating time-series visualizations
C. Converting numerical data into paragraph summaries only
D. Removing all outlier observations regardless of cause
Correct Answer: B. Applying aggregation techniques and creating time-series
visualizations
Explanation: Time-series charts combined with appropriate aggregation reveal
meaningful patterns while reducing short-term variability. Alphabetical
organization provides no analytical value, narrative summaries obscure
, quantitative relationships, and removing all outliers without investigation may
eliminate valid observations.
────────────────────────────────────────
QUESTION 3.
A teacher introduces a block-based programming activity in which students
repeatedly duplicate similar instructions. Which modification best demonstrates
computational thinking through abstraction?
A. Adding more repeated commands for consistency
B. Replacing all variables with constants
C. Creating a reusable procedure or function for repeated tasks
D. Randomizing execution order
Correct Answer: C. Creating a reusable procedure or function for repeated
tasks
Explanation: Abstraction reduces redundancy by encapsulating repeated behavior
into reusable components, improving readability and maintenance. Additional
repetition increases complexity, constants reduce flexibility, and random execution
typically introduces logical errors.
────────────────────────────────────────
QUESTION 4.
A student discovers copyrighted images through an internet search and intends to
include them in a publicly distributed multimedia project. What is the most
appropriate professional response?
A. Use every image because educational projects are always exempt from copyright
restrictions.
B. Remove attribution since crediting the author eliminates copyright concerns.
C. Modify each image slightly so permission is unnecessary.
D. Verify the license or obtain permission before using images not authorized for
reuse.
, Correct Answer: D. Verify the license or obtain permission before using images
not authorized for reuse.
Explanation: Copyright protections remain applicable unless a license, permission,
or other legal exception authorizes use. Attribution alone does not replace
permission, educational use is not automatically exempt, and minor modifications
do not eliminate copyright obligations.
────────────────────────────────────────
QUESTION 5.
A classroom network experiences intermittent slowdowns only when multiple
students simultaneously stream high-definition instructional videos. Which
networking factor is the most likely cause?
A. Bandwidth limitations causing network congestion
B. Incorrect spreadsheet formatting
C. Excessive monitor resolution
D. Low printer toner levels
Correct Answer: A. Bandwidth limitations causing network congestion
Explanation: Simultaneous high-bandwidth activities can exceed available network
capacity, producing congestion and degraded performance. The remaining options
are unrelated to network throughput and would not explain widespread streaming
slowdowns.
────────────────────────────────────────
QUESTION 6.
Which instructional activity most effectively promotes higher-order information
literacy?
A. Memorizing browser shortcut keys
B. Comparing multiple credible sources, evaluating bias, and synthesizing findings
into an evidence-based conclusion
