Question 14

A company needs to store customer orders, where each order can contain multiple items. Which database design is most appropriate?

Accepted Answer

Two tables: Orders and OrderItems, linked by an OrderID foreign key.. It uses a normalized relational design with two tables: Orders (holding order-level data) and OrderItems (holding individual item details per order). The OrderID foreign key in OrderItems creates a one-to-many relationship, allowing each order to contain multiple items without data redundancy or update anomalies. This design ensures referential integrity and efficient querying, which is the standard approach for transactional order systems.

Answer

Three tables: Orders, Customers, and Items, with no direct link.

Answer

A single table storing all data in a JSON column.

Answer

A single table with columns for order details and repeated item information.

Question 15

Which TWO concerns are most critical when selecting a backup method? (Select exactly two.)

Accepted Answer

Recovery time objective. Recovery time objective (RTO) is critical because it defines the maximum acceptable downtime after a failure, directly influencing the choice of backup method (e.g., full vs. incremental) and storage medium (e.g., local disk vs. cloud). A shorter RTO requires faster restoration, often necessitating more frequent backups or technologies like snapshots or replication.

Answer

Network topology

Answer

Display resolution

Answer

Operating system version

Question 16

Which THREE of the following are common features of word processing applications?

Answer

Tracking financial transactions

Question 17

A web application constructs SQL queries by concatenating user input directly. What is the primary security risk?

Accepted Answer

SQL injection. When a web application constructs SQL queries by concatenating user input directly, an attacker can inject malicious SQL code into the query. This allows the attacker to manipulate the database, such as by bypassing authentication, retrieving unauthorized data, or executing arbitrary commands. This is the classic definition of SQL injection, which exploits the lack of input sanitization or parameterized queries.

Answer

Denial of service

Answer

Cross-site scripting

Answer

Buffer overflow

Question 19

A database designer wants to ensure that no two employees have the same email address. Which constraint should be applied to the Email column?

Accepted Answer

UNIQUE. The UNIQUE constraint ensures that all values in the Email column are distinct, preventing any two employees from having the same email address. Unlike PRIMARY KEY, UNIQUE allows NULL values (though typically email columns are set to NOT NULL), and it can be applied to non-key columns. This directly enforces the business rule of unique email addresses without requiring the column to be the table's primary identifier.

Answer

PRIMARY KEY

Answer

CHECK

Answer

FOREIGN KEY
