Shreeji Infrastructure Interview Questions and Answers

Performance testing is a type of testing to ensure software applications perform well under expected workload.

• Performance testing measures the speed, responsiveness, and stability of an application under various load conditions.

• It helps identify bottlenecks, assess scalability, and determine if the system meets performance requirements.

• Types of performance testing include load testing, stress testing, and scalability t...read more

Stress testing is a type of performance testing that evaluates the system's stability and reliability under extreme conditions.

• Simulates high traffic or heavy load on the system

• Helps identify the breaking point of the system

• Measures how the system recovers from stress

• Examples: sending a large number of simultaneous requests to a web server, running multiple applications on a device to test its performance

M20 refers to the mix ratio of concrete, where M stands for mix and 20 represents the compressive strength of concrete in N/mm^2 after 28 days.

• M20 is a commonly used mix ratio in construction for concrete.

• It means 1 part cement, 1.5 parts sand, and 3 parts aggregate.

• The compressive strength of M20 concrete is 20 N/mm^2 after 28 days of curing.

• It is suitable for moderate exposure conditions.

Characteristic compressive strength is the strength of concrete at 28 days of curing.

• It is the maximum compressive stress that a concrete specimen can sustain at 28 days of curing.

• It is used to determine the quality of concrete and its ability to resist loads.

• It is usually expressed in megapascals (MPa).

• For example, a characteristic compressive strength of 30 MPa means that the concrete can withstand a maximum load of
