Reliability design principles in GCP - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is the main goal of reliability design in cloud infrastructure?

To ensure that services and applications stay available and work correctly even when problems happen.

beginner

What does 'redundancy' mean in reliability design?

Having extra copies or backups of components so if one fails, others can take over without stopping the service.

intermediate

Why is 'automated recovery' important in reliability?

It helps fix problems quickly without waiting for a person, reducing downtime and keeping services running smoothly.

intermediate

Explain 'graceful degradation' in cloud services.

When parts of a system fail, the service still works but with fewer features or slower performance instead of completely stopping.

beginner

What role does monitoring play in reliability design?

Monitoring watches the system to find problems early so they can be fixed before causing big failures.

Which of the following best describes redundancy in cloud reliability?

A Having backup components ready to take over if one fails

B Stopping services when errors occur

C Ignoring small failures to save resources

D Manually fixing problems after they happen

Redundancy means having backups so the system keeps working even if one part fails.

What is the purpose of automated recovery in cloud systems?

A To fix issues quickly without human help

B To increase manual checks

C To delay fixing problems

D To shut down services during failures

Automated recovery helps fix problems fast, reducing downtime.

What does graceful degradation allow a system to do?

A Ignore all errors

B Stop working completely when a failure happens

C Continue working with reduced features or performance

D Restart the entire system manually

Graceful degradation means the system still works but with fewer features or slower speed.

Why is monitoring important for reliability?

A To reduce system performance

B To find problems early and fix them quickly

C To avoid detecting failures

D To increase system downtime

Monitoring helps detect issues early so they can be fixed before causing big problems.

Which design principle helps keep services running even if one data center fails?

A Single point of failure

B Manual recovery

C Ignoring failures

D Redundancy across regions

Redundancy across regions means having backups in different locations to avoid total failure.

Describe three key reliability design principles and how they help keep cloud services available.

Think about backups, fixing problems fast, and watching the system.

Explain what graceful degradation means and why it is useful in cloud infrastructure.

Consider how a system behaves when parts fail but it still works.
