Question 1: What is FALSE about SLO? m An SLO is a service level objective: m To begin with, you always get to choose its value m Using hardware or software to monitor system resources and performance • Choosing an appropriate SLO is complex. m A natural structure for SLOB is thus SLI 5 target or lower bound s SLI s upper bound. Question 2: What is the definition of Telemetry? m Monitoring and managing performance and availability of software applications m Using hardware or software to monitor system resources and performance Q Ways for engineers to communicate quantitative data about systems m Highly automated communications process collecting measurements and other data from remote points for monitoring Question 3: How does SRE contribute to ITSM (IT Service Management)? m SRE and ITSM are entirely separate frameworks. m SRE helps with ITSM compliance through automation and engineering. • SRE hinders ITSM compliance activities. m SRE is not mentioned in relation to ITSM. Question 4: What is the definition for Mean Time to Resolution (MTTRe) 0 Average time required to repair/recover a failed component or device. 0 How long it takes for a production-impacting issue to be resolved. 0 How long a vulnerability or software bug/defect exists before its identified. Question 5: Why is exec level support important for the success of BRE implementation? m To increase user growth. m To gain popularity among engineers. m To ensure shared ownership and responsibility. m To reduce the need far allocated funding. Question 6: What is the primary benefit of Infrastructure as Code? m Developers can test their code in production since infrastructure code is treated the same as application code Q The same code is used to create consistent environments in development, test, staging, and production m It sets the stage for containerization m It allows SREs to increase reliability even with more features being pushed into production faster Question 7: Which is NOT a benefit of provisioning with Infrastructure as Code? m Easier testing and auditing of changes in production 0 Consistency across all environments, pre-production, and post-production Q Developers understanding environments to write infrastructure code Q Easier identification of errors in test environments Question B: What is the BEST description of a metric? 0 Used to measure time from when the CI or IT service fails 0 Something that is measured and reported upon io help manage a process, IT service or activity 0 Most minimal version of a product Question 9: What is the primary benefit of regular lire drIlls? Q To ensure the organization can introduce chaos engineering Q To ensure funding for the business continuity plan is adequate Q To ensure the business can continue to operate during unforeseen events or failures Q Identify production incidents before they become major incidents Question 10: What characterizes Open Source Software? m Software distributed with its source code, allowing modification
