Answer-first summary for fast verification
Answer: Implementing automation for immediate recovery from failures., Conducting failure simulations to verify recovery processes.
The correct answers are C and E. Option C, 'Use automation to recover immediately from failure,' is a design principle for reliability because it allows systems to self-heal and minimize downtime. Option E, 'Simulate failures to test recovery processes,' is also correct as it helps ensure that the system can effectively recover from various types of failures. Option A is incorrect because tightly coupled resources can create a single point of failure, which is not resilient. Option B is related to security best practices, not reliability. Option D, while important for performance, does not directly contribute to the system's ability to recover from failures.
