N10-009 COMPTIA NETWORK+ PRACTICE EXAM A network administrator's device is experiencing severe Wi-Fi interference within the corporate headquarters causing the device to constantly drop off the network. Which of the following is most likely the cause of the issue? A. Too much wireless reflection B. Too much wireless absorption C. Too many wireless repeaters D. Too many client connections - (ANSWER)Answer: A Explanation: Severe Wi-Fi interference within a corporate headquarters causing devices to constantly drop off the network is most likely due to too much wireless reflection. Wireless reflection occurs when Wi-Fi signals bounce off surfaces like walls, metal, or glass, causing multipath interference. This can lead to poor signal quality and frequent disconnections. Other causes like wireless absorption, too many repeaters, or too many client connections can also affect Wi-Fi performance, but excessive reflection is a common culprit in environments with many reflective surfaces.

A company wants to implement data loss prevention by restricting user access to social media platforms and personal cloud storage on workstations. Which of the following types of filtering should the company deploy to achieve these goals? A. Port B. DNS C. MAC D. Content - (ANSWER)Answer: D Explanation: To implement data loss prevention (DLP) and restrict user access to social media platforms and personal cloud storage, the company should deploy content filtering. Content filtering examines the data being transmitted over the network and can block specific types of content or websites based on predefined policies. This type of filtering is effective in preventing access to specific web services and ensuring that sensitive information does not leave the network through unauthorized channels. Port, DNS, and MAC filtering serve different purposes and are not as effective for DLP in this context. Reference: CompTIA Network+ Certification Exam Objectives - Network Security section.
