Exam N10-008 topic 1 question 170 discussion

A is the correct answer. Multicast is "communication from one device to only systems that interested in receiving the information." The network technician wants to deploy software to only computers that should receive the software, so multicast is the correct answer. B is incorrect because anycast is "communication from one device that is an option out of many." Anycast communication is delivered to the closest interface, but the network technician wants to deploy it to all computers that need the software. Thus, anycast will not work. C is incorrect because unicast is "communication one device to another and no one else." Unicast is a direct one-to-one communication commonly used for web browsing and file transfers, but we want to deploy the software on the necessary computers as quickly as possible. Thus, unicast will not work. D is incorrect because broadcast is "communication from one device to everyone at once." Broadcast is a one-to-all communication commonly used in our Ethernet networks for the DHCP DORA process, ARP, NDP, etc. We do not want unnecessary to computers to receive the software deployment, so broadcast will not work.

Multicast = From one node to multiple accepting single node systems based on their personal IP & MAC addresses. Anycast = From one node to any node under accepting IP group. This requires IPv6. Unicast = From one node to another accepting node. Broadcast = From one node to every node on the network unless segmented by VLAN, or gateway router IP address.

Norton Ghost Software is a good example of this.

A. Multicast would be the BEST to use in this scenario. Multicast is a method of transmitting a single copy of data to a group of destinations on a network simultaneously. It allows a source to send a single copy of data to a specific group of hosts, rather than sending a separate copy of the data to each individual host. This is an efficient way to deploy software to multiple computers in one classroom, as it reduces network traffic and ensures that all computers receive the software update at the same time.

Multiple computers = One to many = Multicast.

A: In computer networking, multicast is group communication where data transmission is addressed to a group of destination computers simultaneously.

The key words in this question is "MULTIPLE COMPUTERS"
