A user is attempting to open on a mobile phone a HD video that is hosted on a popular media streaming website. The user is receiving connection timeout errors. The mobile reception icon area is showing two bars next to 3G. Which of the following is the most likely cause of the issue?
Answer(s): C
Streaming HD video requires substantial network throughput, typically several Mbps. With only a 3G connection showing two bars, the available bandwidth is likely too limited or inconsistent to sustain an HD stream, resulting in timeouts.
A technician notices that the weekly backup is taking too long to complete. The daily backups are incremental. Which of the following would most likely resolve the issue?
Answer(s): D
Synthetic full backups consolidate the most recent full backup and subsequent incremental backups into a new full backup on the backup storage, without repeatedly reading all data from the production systems. This approach significantly reduces the time impact on the network and source systems during the weekly backup window while still providing a full backup set for restoration.
A help desk technician needs to remove RAM from retired workstations and upgrade other workstations that have applications that use more memory with this RAM. Which of the following actions would the technician most likely take?

Answer(s): A
When you’ve exhausted your troubleshooting expertise and the customer is frustrated, the appropriate next step is to escalate the ticket to a more experienced technician or specialized team.

This maintains transparency, manages expectations, and ensures the issue is resolved as quickly as possible.
