NEW QUESTION # 21
Which of the following statements describes the principal concept behind test driven development?
- A. The only acceptable reason to write a test is to prevent fixed bugs from occurring again.
- B. Instead of testing software automatically, manual tests are performed and logged daily.
- C. Tests may not be written by the same development team that wrote the tested code.
- D. All tests are generated automatically from the tested source code.
- E. Tests are written before the function / method is implemented.
Answer: E
Explanation:
Test-Driven Development (TDD) is a software development process where tests are written before the code that needs to pass the tests is implemented. The principal concept behind TDD is to write a test for a new function or method, see it fail, then write the minimum amount of code required to make the test pass, and finally refactor the code while keeping the tests green.
* Write a Test: Before writing code, a developer writes a test for the desired function or method.
* Run the Test: The new test should fail initially because the function or method hasn't been implemented yet.
* Write Code: Implement the minimum code necessary to pass the test.
* Run Tests: Run all tests to ensure the new code passes and doesn't break any existing functionality.
* Refactor: Clean up the code while ensuring all tests continue to pass.

Which of the following statements is true about load balancers?
- A. Load balancers cannot use connection content, such as HTTP cookies, to route traffic.
- B. Load balancers are a single point of failure because they cannot be deployed redundantly.
- C. Load balancers are a security risk because they obfuscate the origin of connections.
- D. Load balancer help to improve the availability and scalability of a service.
- E. Load balancer require access to private keys in order to be able to forward HTTPS traffic.
Answer: D
Explanation:
Load balancers distribute incoming network traffic across multiple servers, improving the availability and scalability of applications. They help to ensure that no single server becomes overwhelmed, thereby enhancing the overall performance and reliability of the service.
* Availability: Distributing traffic prevents any single server from becoming a bottleneck or point of failure.
* Scalability: Adding more servers behind the load balancer allows the system to handle increased traffic.
* Redundancy: Load balancers can be deployed in a redundant configuration to prevent them from being a single point of failure.

The other options are incorrect:
* A: There is no cloud-init-worker command.
* C: Cloud-init does not replace the instance's original init system.
* D: Cloud-init does not provide a Linux kernel module.
