Which survey includes information about cabling in walls and splitter locations?

The Pre-Installation Survey is the correct choice because it specifically focuses on gathering detailed information about the site where installation will take place. This includes assessing the existing physical infrastructure, such as cabling in walls and splitter locations, which are crucial for ensuring proper layout and connectivity of the network. By evaluating these elements before installation begins, technicians can identify potential challenges and plan accordingly, leading to a more efficient and effective installation process.

In contrast, a Site Evaluation Survey typically provides a broader look at the overall environment and suitability for a network but may not dig into specific details about cabling and splitters. A Post-Implementation Review occurs after installation to assess the project's success and is not utilized for gathering preliminary information. Lastly, a Network Assessment usually refers to evaluating the performance and health of an existing network rather than the specific infrastructure setups prior to installation.
