Question 1

Where should the variables that a program uses be defined?
A) At the end of a program
B) In the middle of a program
C) At the top of the program
D) When the code needs it

Accepted Answer

The variables should be defined at the top of the program to make it clear and easy to read for other programmers. This is also a common convention in most programming languages.

Question 2

A method's signature is an example of limited code.

Accepted Answer

A method's signature is a concise way of representing its input parameters and return type, which can be helpful for readability and understandability of the code. However, it is not necessarily limited in its functionality or scope.

Question 3

Parameter-driven software is software that looks up values stored in a database and determines what to display, allow, or execute based on those values.

Accepted Answer

Parameter-driven software relies on values stored in a database to make decisions and determine what action to take.

Question 4

After the debug methods are built into the program, they can be called anywhere at anytime within the program you need to test.

Accepted Answer

Once the debug methods are integrated into the program, they can be called from anywhere to test and fix various errors in the program.

Question 5

How can an application alert stakeholders of invasion?
A) cancel the user's password
B) send out SMS messages
C) log the activity in a log file
D) catch all errors

Accepted Answer

Sending out SMS messages is the most effective way of alerting stakeholders of an invasion in real-time, as it is likely to be noticed quickly. Cancelling the user's password and catching all errors may be beneficial, but they do not provide immediate notification of an invasion. Logging the activity in a log file may help with future analysis, but it does not alert stakeholders in real-time.

Question 6

Which program language is vulnerable to a buffer overflow attack?
A) JAVA
B) C++
C) PHP
D) Perl

Accepted Answer

C++ is vulnerable to buffer overflow attacks due to its lack of built-in memory management safeguards. It allows direct memory access and manipulation, leaving it open to exploitation by attackers. While other programming languages, such as Java, PHP, and Perl, can also be vulnerable, C++ is considered the most susceptible.

Question 7

What is it called when developers write a piece of software for a specific purpose
A) software diversity
B) code unit
C) parameter-driven code
D) limited code

Accepted Answer

The answer of What is it called when developers write...

Question 8

What is it called when existing bodies of logic are broken up and moved into many smaller bodies of code?
A) reusable code
B) refactor code
C) code review
D) code debugging

Accepted Answer

The process described is called refactoring, which involves reorganizing code to improve its structure and maintainability without changing its external behavior. This can be done by breaking up existing bodies of logic into smaller, more modular pieces of code. Option A, reusable code, refers to code that can be used multiple times throughout a program or across multiple programs. Option C, code review, involves analyzing code to identify errors or areas for improvement, but does not necessarily involve breaking up existing logic. Option D, code debugging, refers to the process of identifying and fixing errors in code, but again does not necessarily involve breaking up existing logic.

Question 9

It is best to wait to add debugging techniques to the code when the code is broken.

Accepted Answer

Debugging techniques should be incorporated throughout the development process, not just when there is an issue with the code. It can be helpful to catch and address potential issues before they cause larger problems.

Question 10

Which item is NOT a characteristic of self-monitoring code?
A) Canceling user passwords
B) Requiring physical requests for data
C) Code refactoring
D) Alerting stakeholders of invasion

Accepted Answer

The answer of Which item is NOT a characteristic of...

Question 11

When reusable code gets buried into other code, the logic can and should be reused by other use cases.

Accepted Answer

When reusable code is buried within other code, it becomes difficult to access and reuse, which defeats the purpose of creating reusable code. Reusable code should be modular and easily accessible for different use cases.

Question 12

How should a developer code for DEBUGS?
A) Add the DEBUG statements in when needed
B) Build the debug logic into the code while developing
C) Use a debug editor
D) Use a peer review process

Accepted Answer

It is best to build the debug logic into the code while developing, as this allows for easier and more efficient debugging. Debug statements can clutter the code and should only be used when necessary. Debug editors and peer review processes can be helpful, but building in debug logic is the most effective way to ensure easy debugging.

Question 13

What type of software looks up values stored in a database and determines what to display, allow, or execute based on those values
A) limited code
B) software diversity
C) parameter-driven
D) debugging

Accepted Answer

Parameter-driven software retrieves data from a database and uses those values to determine what actions to perform, what information to display, and what permissions to grant. This type of software is commonly used in web applications and enterprise-level systems for managing user access and determining user roles. Limited code refers to software with strict code limitations, software diversity is not related to the context of the question, and debugging is the process of finding and fixing errors in software.

Question 14

If logic bombs or Trojan horses were to be snuck in, what type of file would the easiest target?
A) JAR files
B) Java files
C) SQL scripts
D) ANT scripts

Accepted Answer

JAR files are executable Java archive files that contain multiple files and are commonly used to distribute Java applications. Because JAR files contain executable code, they are a common target for attackers attempting to sneak in logic bombs or Trojan horses. Therefore, JAR files are the easiest target among the given options.

Question 15

What design pattern forces the server to create only one object in its heap, thus making the server run very efficiently while using minimum RAM?
A) MVC
B) Template
C) Singleton
D) Abstract

Accepted Answer

The Singleton design pattern ensures that only one object of the class is created and no other object can be created. This is useful in scenarios where there is a need to maintain only one object of a class throughout the application, like in a database connection object or a configuration object. By creating only one object, the server can run efficiently and use minimum RAM. Therefore, the Singleton pattern is a good choice in such scenarios. The other options such as MVC, Template, and Abstract are design patterns but do not have the same benefits as the Singleton pattern in this scenario.

Question 16

What is the best way to turn off DEBUG statements in the code?
A) automate a script
B) look at the code and manually turn them off
C) leave them on since the information only goes to a log file
D) Use the IDE to turn them off

Accepted Answer

The answer of What is the best way to turn...

Question 17

What is it called when software is developed on the premise that specifications, data, and environments will change?
A) software diversity
B) limited code
C) parameter-driven code
D) debugging code

Accepted Answer

Question 18

If requesting the application to provide sensitive information over the public network can sometimes be too risky, what should be done?
A) Take the chance and send the data
B) Log all activity
C) Send it but encrypt the data
D) Requiring Physical Requests for Data

Accepted Answer

The answer of If requesting the application to provide sensitive...

Question 19

Which option is NOT a characteristics of Organized code?
A) Import only the classes that are needed to run the program
B) Avoid spaghetti code
C) Declare variables he program uses at the top
D) Use an IDE

Accepted Answer

All of the other options are characteristics of organized code. Using an IDE is not a necessary characteristic, although it can be helpful in organizing and writing code.

Question 20

What should the application do if the user has failed to log in after 5 attempts?
A) allow the user to keep trying
B) cancel the user and force them to request a new id
C) cancel the user for 24 hours
D) cancel the user's password

Accepted Answer

The answer of What should the application do if the...
