Final answer:
The help desk should be contacted for assistance when Sophia is having trouble with the company's e-mail program and when Horatio is facing issues with the new project management tracking system. These scenarios involve technical difficulties where help desk support can provide immediate troubleshooting and solutions.
Step-by-step explanation:
In scenarios where individuals are having trouble with technology or need specific guidance on using a company's systems, they should contact a help desk for assistance. The appropriate scenarios are:
- Sophia is having trouble developing an invitation list using her company's e-mail program. She is not sure what she is doing wrong. - Since she is experiencing issues with an existing system, the help desk can provide troubleshooting support.
- Horatio is having problems inputting his time using the company's new project management tracking system. - Similarly, Horatio's issues with the time tracking system are exactly the sort of technical problems a help desk is equipped to resolve.
The other scenarios, such as Bella signing up for training or Alfonso wanting to set up a training session, are proactive measures that do not usually require immediate help desk support but instead involve scheduled training and planning, which could be resolved without the help desk unless the assistance is related to organizing or technical issues with the training tools themselves.
