A high failure rate of changes duringPost Implementation Review (PIR)inITIL’s change management process suggests a deficiency in theassessment and evaluation of change requests(A). Proper assessment involves analyzing risks, impacts, and feasibility before approving changes. If this step is inadequate (e.g., overlooking conflicts or underestimating impacts), changes are more likely to fail, as they may not align with objectives or be poorly planned.

Insufficient resources (B):May cause delays but is less directly tied to failed objectives compared to poor assessment.

CAB meetings not taking place (C):The CAB reviews changes, but the scenario doesn’t indicate meetings are absent; poor assessment can occur even with CAB involvement.

Insufficient budget (D):May limit implementation but is less likely the primary cause of failed objectives.

For a government system handling land title transfers, the key requirements arespeed of transmissionandprivacy. Aprivate blockchainis most suitable because it restricts access to authorized participants, ensuring privacy and confidentiality of sensitive data such as land ownership records. Private blockchains are controlled by a single organization or a limited group, allowing faster transaction processing compared to public blockchains, which require consensus from a large, decentralized network. This aligns with the need for quick and secure transactions in a controlled environment.

Public blockchains (B) are open to anyone, which compromises privacy for sensitive government data. Community blockchain (A) is not a standard term in blockchain technology, and consortium blockchains (D), while involving multiple organizations, are less suitable for a single government entity needing full control.

To ensurecontinuityin vendor selection, the key criteria includehead count(vendor’s staffing capacity to deliver services),support(availability of ongoing technical and operational support), andfinancial stability(ensuring the vendor remains viable to provide services long-term). These factors directly impact the vendor’s ability to maintain service delivery without interruptions, which is critical for business continuity.

Scope, maintenance, and price (A):Scope and price are important but don’t directly ensure continuity; maintenance is a subset of support.

Terms and conditions, maintenance, and terms of engagement (B):These are contractual elements, but they don’t fully address operational continuity like staffing or financial stability.

Price, training, and support (C):Training is less critical for continuity compared to staffing capacity or financial health.

According tovendor management frameworks, continuity is ensured by evaluating the vendor’s operational capacity and long-term reliability, making head count, support, and financial stability the minimum criteria.

Ause caseoruser storydescribes interactions between a user (role) and the system to achieve a specific goal, defining what the system must do. This corresponds to afunctional requirement(A), which specifies the system’s features or capabilities (e.g., “the system shall allow users to submit a return request”). According toSDLCand requirements engineering, functional requirements focus on specific functionalities, as captured in use cases.

Behavioral requirement (B):Not a standard term; it may refer to system behavior but is less specific than functional requirements.

Non-functional requirement (C):Covers performance, scalability, or usability (e.g., response time), not specific user interactions.

Security requirement (D):A subset of non-functional requirements focused on security, not general use case interactions.

For abusiness continuity planrequiring a site to facilitate desks for workers, ahot site(A) is recommended. A hot site is a fully equipped, operational facility with real-time data replication, allowing immediate resumption of operations with minimal downtime. According toISO 22301, hot sites are ideal for critical operations requiring desks, IT infrastructure, and immediate availability for workers to continue business processes post-disaster.

Cold site (B):A basic facility with minimal equipment, requiring significant setup time, unsuitable for immediate worker use.

Warm site (C):Partially equipped with some infrastructure but not fully operational, requiring setup time.

Mobile site (D):A temporary, portable solution, less suitable for sustained operations compared to a hot site.
