Chaos engineering quiz (5/5/2023)

what does chaos engineering help us to accomplish?

• Helps you preemptively find issues

• • Increases confidence in the resiliency of your system

• • Helps you identify and alleviate areas with technical debt

• All of the above

This defines what term below?

a practice that balances the tension between development and operations, and allows for data driven decisions in moving from new features to reliability development.

• SWE

• SRE

• SLI

• SLO

Which of the choices below is defined by the following?

a specific metric, that helps companies measure some aspect of the level of service to their customers (such as latency)

• SLA

• SLI

• SLO

Answer explanation

A SLI - is a specific metric, that helps companies measure some aspect of the level of service to their customers

what does SLI stand for

• Service level index

• Service level intimidator

• Service Level Indicator

• Service level inflection point

What makes a good SLI?

• Represents user experience

• its Specific

• Architecture-agnostic

• All of the above

what does SLO stand for

• Service level observation

• Service level objective

• service level oscillation

• service level objection

What makes a good SLO?

• Represents user expectations

• Defensible

• Represents business value

• all of the above

The following is the definition of what term?

• Allowable amount of time to not meet SLO target within a rolling time period.

• or A measurement of how much error or downtime your system can withstand before the SLO is breached

• Downtime Budget

• Error period

• Error budget

Answer explanation

the allowable amount of time to not meet a SLO, is your "Error Budget"

note: Once this time (error budget) is depleted, you would switch from feature development to reliability development

which of the following is true, as you go from 99.99% uptime to 99.999% up time?

• not breaching the 99.999% SLO, takes exponentially more money and effort then 99.99%

• the user tends to not even notice how much more reliable the system is then when it had 99.99% up time

• the user usually doesnt care about this extremely small incremental improvement

• all of the above

whats one of the "four golden signals of monitoring"?
