Authentic CompTIA Certification Exam N10-009 Questions Answers

224.0.0.1 is a multicast address that allows packets to be sent to all hosts within a multicast group. Since video streaming often uses multicast to efficiently distribute data to multiple clients without unnecessary duplication, this is the correct answer.

•Why not the other options?

•127.0.0.1 (A) – This is the loopback address used for internal device testing, not for multicast traffic.

•172.17.1.1 (B) – This is a private unicast address, meaning it can only send packets to one specific host.

•240.0.0.1 (D) – This falls within the reserved experimental IP address range and is not used for multicast.

Microwaves are known to interfere with the 2.4GHz frequency, which is the same frequency used by many wireless networks. This can cause signal degradation and intermittent connectivity issues, especially if the WAP is placed near such devices.

=================

An Extended Service Set Identifier (ESSID) allows multiple access points to share the same SSID, enabling seamless roaming for users. This means that users can move between different access points within the same ESSID without losing connection or having to reauthenticate. This provides a better user experience, especially in large environments such as office buildings or campuses.References: CompTIA Network+ study materials. ​
