What are the two common best principles of software applications in the
development process? Choose 2 answers.
Quality code
Secure code
Information security
Integrity
Availability - CORRECT ANSWER Quality code
Secure code
"Quality code" is correct. Quality code is efficient code that is easy to maintain
and reusable.
"Secure code" is correct. Secure code authorizes and authenticates every user
transaction, logs the transaction, and denies all unauthorized requisitions.
What ensures that the user has the appropriate role and privilege to view data?
Authentication
Multi-factor authentication
Encryption
Information security
Authorization - CORRECT ANSWER Authorization
Authorization ensures a user's information and credentials are approved by the
system.
Which security goal is defined by "guarding against improper information
modification or destruction and ensuring information non-repudiation and
authenticity"?
Integrity
Quality
Availability
Reliability - CORRECT ANSWER Integrity
,The data must remain unchanged by unauthorized users and remain reliable from
the data entry point to the database and back.
Which phase in an SDLC helps to define the problem and scope of any existing
systems and determine the objectives of new systems?
Requirements
Design
Planning
Testing - CORRECT ANSWER Planning
The planning stage sets the project schedule and looks at the big picture.
What happens during a dynamic code review?
Programmers monitor system memory, functional behavior, response times, and
overall performance.
Customers perform tests to check software meets requirements.
An analysis of computer programs without executing them is performed.
Input fields are supplied with unexpected input and tested. - CORRECT ANSWER
Programmers monitor system memory, functional behavior, response times, and
overall performance.
How should you store your application user credentials in your application
database?
Use application logic to encrypt credentials
Store credentials as clear text
Store credentials using Base 64 encoded
Store credentials using salted hashes - CORRECT ANSWER Store credentials using
salted hashes
Hashing is a one-way process that converts a password to ciphertext using hash
algorithms. Password salting adds random characters before or after a password
prior to hashing to obfuscate the actual password.
Which software methodology resembles an assembly-line approach?
V-model
Agile model
Iterative model
, Waterfall model - CORRECT ANSWER Waterfall model
Waterfall model is a continuous software development model in which the
development steps flow steadily downwards.
Which software methodology approach provides faster time to market and higher
business value?
Iterative model
Waterfall model
V-model
Agile model - CORRECT ANSWER Agile model
In the agile model, projects are divided into small incremental builds that provide
working software at the end of each iteration and adds value to business.
In Scrum methodology, who is responsible for making decisions on the
requirements?
Scrum Team
Product Owner
ScrumMaster
Technical Lead - CORRECT ANSWER Product Owner
The Product Owner is responsible for requirements/backlog items and prioritizing
them.
What is the reason software security teams host discovery meetings with
stakeholders early in the development life cycle?
To determine how much budget is available for new security tools
To meet the development team
To refactor functional requirements to ensure security is included
To ensure that security is built into the product from the start - CORRECT ANSWER
To ensure that security is built into the product from the start
To correctly and cost-effectively introduce security into the software
development life cycle, it needs to be done early.
