The primary area of focus when an organization decides to outsource technical support for its external customers is to align service level agreements (SLAs) with current needs. SLAs are contracts that define the scope, quality, and expectations of the services provided by the vendor, as well as the remedies or penalties for non-compliance. SLAs are essential for ensuring that the outsourced technical support meets the customer' s requirements and satisfaction, as well as the organization's objectives andstandards. By aligning SLAs with current needs, the organization can specify the key performance indicators (KPIs), metrics, and targets that reflect the desired outcomes and value of the technical support. This can also help to monitor and evaluate the vendor's performance, identify gaps or issues, and implement corrective actions or improvements.

Asset life cycle management is a technique of asset management where facility managers maximize the usable life of assets throughplanning, purchasing, using, maintaining, and disposing of assets1. The mainaim of assetlife cycle management is to reduce costs and increase productivity by optimizing the performance, reliability, and lifespan of assets2. Asset life cycle management can help prevent the situation of having unused applications by ensuring that the applications are aligned with the business needs, objectives, and strategies, and that they are regularly reviewed, updated, or retired as necessary3.
The other options are not as effective as asset life cycle management for preventing unused applications. A formal request for proposal (RFP) process is a method of soliciting bids from potential vendors or suppliers for a project or service. A RFP process can help select the best application for a specific requirement, but it does not ensure that the application will be used or maintained throughout its lifecycle. Business case development procedures are a set of steps that involve defining the problem, analyzing the alternatives, and proposing a solution for a project or initiative. Business case development procedures can help justify the need and value of an application, but they do not guarantee that the application will be utilized or supported after its implementation. An information asset acquisition policy is a document that outlines the rules and standards for acquiring information assets such as applications. An information asset acquisition policy can help ensure that the applications are acquired in a consistent and compliant manner, but it does not address how the applications will be managed or disposed of after their acquisition.

The most effective way to minimize downtime during system conversions is to use a parallel run. A parallel run is a method of system conversion where both the old and new systems operate simultaneously for a period of time until the new system is verified to be functioning correctly. Thisreduces the risk of errors, data loss, or system failure during conversion and allows for a smooth transition from one system to another. References: CISA Review Manual, 27th Edition, page 467

A single point of failure is a component or system that, if it fails, will cause the entire system to stop functioning. In virtual environments, the hypervisor is the software layer that enables multiple virtual machines to run on a single physical host. If the hypervisor is compromised, corrupted, or unavailable, all the virtual machines running on that host will be affected. This can result in data loss, downtime, or security breaches.
