Security+ Set Q

Question 1

QA (quality assurance)

Answer 1

policies, procedures, and tools designed to ensure defect-free development and delivery

Question 2

QoS (quality of service)

Answer 2

systems that differentiate data passing over the network that can reserve bandwidth for particular applications. A system that cannot guarantee a level of available bandwidth is often described as Class of Service (CoS). Also known as CoS.

Question 3

qualitative analysis

Answer 3

a risk analysis method that uses opinions and reasoning to measure the likelihood and impact of risk

Question 4

quantitative analysis

Answer 4

a risk analysis method that is based on assigning concrete values to factors.

Question 5

quantum cyrptography

Answer 5

using quantum computing for cryptographic tasks, such as distributing keys or cracking crypto systems. Quantum computing works on the principle that its units (qubits) have more properties than the bits used in “classical” computers, notably (and very crudely) that a qubit can have a probability of being 1 or 0 and that inspecting the value of one qubit can instantly determine that of others (entaglement).
