Hypothesize Verify Collaborate and Research Learn - not confirmed What is a consequence of working in isolation on long-lived code branches? Deployments will fail Rollbacks will be difficult Trunk/main will not always be in a deployable state Static analysis tests will fail What identifies potential changes to the current-state Value Stream that could improve flow? Future-state mapping Value Stream identification Impact mapping Problem-solving workshop Which incident response practice most strongly suggests a lack of DevOps culture? On-call developers Frequent fix-forward changes Manual rollback procedures Frequent server reboots • Trunk/main will not always be in a deployable state • Future-state mapping • Manual rollback procedures Explanation: • The trunk-based development is where all the developers (for a certain deployable unit) commit to a single shared branch under source-control. This branch is referred to as the 'trunk'. It includes continuous integration and continuous delivery. In order words, it comprises no long-lived branches as they make continuous delivery impossible. Here, the team requires merging back as earliest as possible, at most once a day. • Value Stream Mapping is referred to as a planning tool that is utilized to analyze the current state furthermore develop the future state for a sequence of events that takes the service or product from the starting of the particular process until it reaches the user. It represents both data and materials as they progress through the process. The future state mapping determines improvement to be implemented to the value stream, which will shorten the entire lead time. It represents the picture of the lean transformation process for a particular value stream. • The primitive principles of DevOps are fast reply to feedback, continuous delivery, and automation. The DevOps relies on automation to facilitate speed, repeatable processes, consistency, and environment development. It simply recognized that the manual processes are the enemy of high productivity, fast value delivery, and safety. Moreover, here automation is not only saving time. It improves development, testing, packaging, and implementation of the processes that could be made routine. Automation also provides faster response and learning to market demand and user feedback. Moreover, frequent-fix forward changes or on-call developers are the technical support for fast recovery.Reference: https://www.emsstrategies.com/dd020107article.html Reference: https://www.scaledagileframework.com/devops/37. What is a consequence of working in isolation on long-lived code branches?

To track the results of automated test cases for use by corporate audit To generate synthetic test data inputs in order to validate test scenarios for automated tests maintained in version control To automate provisioning data to an application in order to set it to a known state before testing begins To truncate data from the database to enable fast-forward recovery To provide a viable option for disaster-recovery management 39. What organizational anti-pattern does DevOps help to address?

Which two skills appear under the Respond sub-dimension? (Choose two.) Automatic rollback Version control Cross-team collaboration Telemetry Service virtualization 41. What differentiates Deployment and Release in the Continuous Delivery Pipeline? Deployment is performed by Development; release is performed by Operations Deployment occurs every iteration; release occurs at PI boundaries Deployment involves moving value to production; release involves making value available to end users Deployment is done on a cadence; release is done on demand 33. Which statement describes what could happen when Development and Operations do not collaborate early in the pipeline? Teams build things quickly but build the wrong things Lead times are reduced Automation of integration test is not possible Surprises are found in deployment that lead to significant rework and delay 34.
