Which one of the following considerations has the LEAST impact when considering transmission security?

Network bandwidth is the least important consideration when considering transmission security, as it is more related to the performance or efficiency of the network, rather than the security or protection of the data. Network bandwidth is the amount of data that can be transmitted or received over a network in a given time period, and it can affect the speed or quality of the communication1. However, network bandwidth does not directly impact the confidentiality, integrity, or availability of the data, which are the main goals of transmission security. Network availability, data integrity, and node locations are more important considerations when considering transmission security, as they can affect the ability to access, verify, or protect the data from unauthorized or malicious parties. References: 1: CISSP All-in-One Exam Guide, Eighth Edition, Chapter 7, page 402.
