Which statement correctly describes containers compared with virtual machines?
Answer: Containers share the OS kernel and isolate application runtime environments lightweightly
Containers share the host OS kernel and run applications with their dependencies isolated.
Which description best matches edge computing?
Answer: Processing data close to sensors or devices to reduce latency and traffic
In IoT and similar contexts, processing near devices helps improve real-time behavior and reduce communication volume.
Which description best matches the zero trust model?
Answer: Do not assume trust inside or outside the network; continuously authenticate, authorize, and verify
Zero trust emphasizes verifying each access rather than relying only on perimeter defense.
What is binary 1010 converted to decimal?

Which description of logical AND is correct?
Answer: It is true only when both operands are true
AND is true only when both conditions are true. Also understand OR, NOT, and XOR.
Which condition is required for binary search?
Answer: The target data is sorted

Which description of a foreign key in a relational database is correct?
Answer: A key that references a primary key or similar key in another table and represents relationships between tables
A foreign key represents a reference relationship between tables and helps maintain referential integrity.
