HVIT Sample Test 1 questions Flashcards
A centralized IT department is adopting site reliability engineering to increase the resilience and performance of IT systems.
What is this an example of?
A. High velocity IT
B. Digital technology
C. IT transformation
D. Digital transformation
C. IT transformation
A business analyst has recognized that business managers have conflicting hypotheses about their needs for departmental improvement. They also find it difficult to articulate their requirements.
Which approach is BEST for obtaining requirements?
A. Conduct an interview based on a carefully prepared script of detailed questions
B. Allocate a week to analyse how the department works, and then make logical conclusions
C. Develop multiple prototypes of a possible solution, and adopt what works best
D. Ask the director to enforce what the business analyst considers to be the most plausible solution
C. Develop multiple prototypes of a possible solution, and adopt what works best.
The conflicting hypotheses of the business managers and their difficulty in articulating their requirements indicate that this is a complex context. “Complex – Unclear and unknowable causality requiring safe-to-fail experimentation (emergent practice)”.
An organization wants to introduce chaos engineering. Various experiments will be conducted in the production environment to see how it responds.
Which is an example of an extra service continuity management measure to support this way of working?
A. Logging information about bandwidth, throughput, response times, and other performance data during the periods of experimentation
B. Investigating the results of the experiments to identify potential vulnerabilities in the production environment
C. Validating backup network connectivity and testing it for the anticipated workload
D. Providing a clear set of service models to understand the impact of service outages on business activities
C. Validating backup network connectivity and testing it for the anticipated workload.
“Designing service continuity measures with sufficient resilience and redundancy to cope with the unexpected outages caused by chaos engineering tools” is a service continuity management activity associated with chaos engineering
A service provider spends a long time carefully planning and designing its new services with its customers and users. There is high customer and user satisfaction with the services when they are introduced. The satisfaction levels dramatically reduce for most services during the first year of live operation.
Which is the BEST approach to improve this situation?
A. Introduce a phased approach to the design
B. Improve the measurement and metrics of the new services
C. Increase the length of the initial service design activity
D. Offer free service upgrades to customers when their satisfaction levels start to dip
A. Introduce a phased approach to the design.
“It is important to consider iterative and incremental approaches to service design, which can ensure that products and services introduced to live operation can continually adapt in alignment with the evolving needs of the organization and its customers.”
A financial organization is adopting a DevOps approach to the development and management of digital products. The organization is subject to strict regulation and undergoes external audits every year.
Which practice would BEST help to support the HVIT objective of assured conformance?
A. Risk management
B. Relationship management
C. Availability management
D. Infrastructure and platform management
A. Risk management.
“Creating a balanced and practical approach between enterprise risk management, technical risk management, and new ways of working” is how the ‘risk management’ practice contributes to the objective of assured conformance.
A service provider plans to launch a number of mobile phone apps into a new but volatile market where speed to market and regular enhancements are essential to build competitive advantage.
What contribution is made by the ‘software development and management’ practice to achieving this advantage?
A. Analysing and documenting user requirements to ensure that their expectations are met
B. Leveraging infrastructure as code to support the need to make rapid changes to the apps
C. Ensuring that the ‘definition of done’ includes non-functional requirements to reduce the likelihood that the apps will fail in the live environment
D. Prioritizing the requirements so that the expenditure used to develop the mobile apps provides the appropriate return on investment
B. Leveraging infrastructure as code to support the need to make rapid changes to the apps.
The ‘software development and management’ practice should be involved in deciding the approach taken to developing software quickly and reliably. The software development and management practice success factor “agree and improve an organization’s approach to development and management of software”, “concerns itself with the tactical decision to select from this pre-defined set of approaches, the best approach for each software product, based on the organization’s requirements for the product”. The ‘software development and management’ practice contributes to fast development by “Developing software architecture and code to leverage fast delivery/provisioning of virtual hardware infrastructure”.
An organization has found that poor website speed is having an impact on customer experience and is causing the organization to lose sales. The organization has challenged the IT department to remedy the matter prior to the launch of a new marketing campaign.
Which is the BEST technique that the capacity and performance management practice can consider to address this problem?
A. ChatOps
B. Site reliability engineering (SRE)
C. AIOps
D. Chaos engineering
C. Correct. This approach recommends proactive monitoring and also takes into consideration the need for capacity planning relative to the marketing campaigns. “AIOps platforms are used to enhance and partially replace many primary IT operations functions, such as availability and performance monitoring, failure recognition, predictive analysis, and event correlation and analysis.” “AIOps provides capabilities for identifying patterns and anomalies, determining the capacity and utilization of assets, and planning the capacity of future products or services.”
Which TWO of the service value chain activities are the MOST closely related to the high-velocity IT objective of ‘fast development’?
A. ‘Obtain/build’ and ‘design and transition’
B. ‘Design and transition’ and ‘deliver and support’
C. ‘Deliver and support’ and ‘obtain/build’
D. ‘Design and transition’ and ‘resilient operations’
A. ‘Obtain/build’ and ‘design and transition’.
“The fast development objective is mainly achieved by the application development and infrastructure engineering that takes place as part of the design and transition and obtain/build value chain activities”.
