- A) Managing lifecycle of services
- B) Managing database transactions
- C) Optimizing memory usage
- D) Handling API requests
Answer: A) Managing lifecycle of services
Explanation: Dependency Injection in .NET Core is used to manage the lifecycle and dependencies of services, promoting loose coupling and easier unit testing.
Question 3: In Entity Framework Core, which of the following is used to create database schema from your models?
- A)
Add-Migration - B)
Update-Database - C)
Create-Database - D)
DbContext.SaveChanges()
Answer: A) Add-Migration
Explanation: Add-Migration is used to generate migration files, which can then be applied to create or update the database schema.
Section 3: Quiz for Golang Programming

Question 1: In Go, which of the following data types is not implicitly initialized with zero values?
- A)
int - B)
float64 - C)
map - D)
string
Answer: C) map
Explanation: In Go, types like map, slice, and channel are initialized as nil (not zero values), whereas other types like int, float64, and string are initialized to 0, 0.0, and "" respectively.
Question 2: Which keyword is used in Go to declare a constant?
- A)
constant - B)
var - C)
const - D)
define

- A)
return err; if err != nil - B)
err.throw() - C)
error.handle() - D)
