Explanation & Hint:
Two valid examples of beaconing traffic that may occur within an organization’s network are:
- 802.11 WLAN keepalive traffic: Wireless networks, including those using the 802.11 standard, often generate keepalive traffic to maintain connections. These periodic signals sent by wireless devices to the access point can be considered a form of beaconing, as they are regular, automated communications to ensure connectivity and network presence.
- NTP (Network Time Protocol) traffic: NTP is used to synchronize the clocks of computers over a network. The traffic generated by NTP can be considered a form of beaconing because it involves regular, scheduled communication between a client and an NTP server to maintain accurate time settings.
The other options do not represent typical beaconing traffic:
- 6G wireless: This refers to a future generation of wireless technology and is not specific to a type of network traffic or pattern.
- OSI Layer 1 IP traffic: OSI Layer 1 refers to the physical layer, which deals with the hardware transmission of raw bits over a physical medium and does not deal with IP traffic specifically.
- Client-server ping traffic: While regular ping traffic between a client and server could be considered a form of beaconing, it’s less common as a routine network function compared to WLAN keepalive or NTP traffic. Regular pings are more often used for diagnostic purposes rather than as a standard network function.
