A developer embeds a query in a high-level program to extract information from a database. This is an example of:

• database direct access.

• database utility access.

• database programmatic access.

• database manual access.

Answer explanation

A developer embedding a query in a high-level program to extract information from a database is an example of database direct access. This method involves using programming languages to interact with the database, allowing for more control and flexibility in data retrieval and manipulation.

Which of the following will a company do to update a customer’s address while using a flat file database?

• Update the address for each order the customer placed.

• Update the address in the customer address table.

• Update the address field in the customer order table.

• Update the primary key to reflect the customer’s address.

Answer explanation

In a flat file database, data is stored in a single table, so updating a customer's address would require updating the address field in the customer order table. This is because there is no separate customer address table or primary key related to the address in a flat file database.

A systems administrator wants to run a script but does not have access to the graphical user interface. Which of the following can be used to run scripts?

• Text editor

• Word processor

A security administrator is adding accounting features to a web application. Which of the following would be the BEST action?

• Enhance the granularity of user permissions.

• Enable an audit log.

• Implement smart card login.

• Adopt a procedure for adding accounts.

Answer explanation

Implementing smart card login is the best action for adding accounting features to a web application because it provides an additional layer of security through two-factor authentication. This ensures that only authorized users can access the application, enhancing the overall security and integrity of the accounting features.

A developer is in the process of creating a program and has started to draft the logic of the code. This process is an example of:

• drawing a value stream map.

• developing pseudocode.

• identifying functions.

• compiling the language.

Answer explanation

The question is about the process a developer undergoes when drafting the logic of a program. The correct answer is 'developing pseudocode.' Pseudocode is a simple way of writing programming code in English. It is a step in the programming process that helps developers plan out and visualize the logic of their code before writing the actual program.

Which of the following is the WEAKEST link in the security posture of an organization?

• Technology

• Infrastructure

• People

• Regulations

Answer explanation

The weakest link in the security posture of an organization is often the people. Despite having advanced technology, robust infrastructure, and strict regulations, human error or negligence can lead to security breaches. Therefore, people are considered the weakest link in an organization's security posture.

A technician is installing a plug-and-play USB mouse. Which of the following must the technician do to complete the installation?

• Manually install the driver software.

• Connect the mouse.

• Configure the USB port.

• Download the driver software.

Answer explanation

The question asks about the necessary step a technician must take to install a plug-and-play USB mouse. The correct answer is 'Connect the mouse.' This is because plug-and-play devices like a USB mouse are designed to be recognized and configured automatically by the computer once they are connected, eliminating the need for manual driver installation or USB port configuration.

Which of the following programming constructs would be used to repeat a statement 100 times in a loop?

• IF

• ELSE

• RETURN

• WHILE

Answer explanation

The correct answer is 'WHILE'. In programming, a 'WHILE' loop is used to repeat a statement or group of statements while a given condition is true. It tests the condition before executing the loop body. So, it can be used to repeat a statement 100 times by setting the condition accordingly.

Which of the following has the longest range?

• NFC

• Bluetooth

• WiFi

• Infrared

Answer explanation

The question asks which of the given options has the longest range. The options were NFC, Bluetooth, WiFi, and Infrared. Among these, WiFi has the longest range. While NFC and Infrared have a very short range, Bluetooth's range is moderate. However, WiFi can cover a much larger area, making it the correct answer.

A programmer is creating a program that makes a decision based on user input and has decided to use a branching statement. Which of the following commands would be BEST for the programmer to use?

• IF THEN

• WHILE

• FOR

• BEGIN

Answer explanation

The question asks about a branching statement in programming, which is used to make decisions based on user input. The 'IF THEN' command is the best choice for this purpose. It allows the program to execute a certain block of code if a specified condition is true. The other options, 'WHILE', 'FOR', and 'BEGIN', are not typically used for decision-making based on user input.
