Refer to the exhibit. Drag and drop the learned prefixes from the left onto the subnet masks on the right. <DragDrop items={["172.16.3.128","172.16.3.64","172.16.2.128","172.16.3.192","172.16.4.0"]} slots={[{"answer":"172.16.4.0","id":"s1","label":"255.255.254.0"},{"answer":"172.16.2.128","id":"s2","label":"255.255.255.128"},{"answer":"172.16.3.64","id":"s3","label":"255.255.255.224"},{"answer":"172.16.3.128","id":"s4","label":"255.255.255.240"},{"answer":"172.16.3.192","id":"s5","label":"255.255.255.248"}]} explanation={"Each learned route in the routing table includes a CIDR prefix length. Converting those prefix lengths to dotted-decimal masks gives the correct matches: 172.16.2.128/25 = 255.255.255.128, 172.16.3.64/27 = 255.255.255.224, 172.16.3.128/28 = 255.255.255.240, 172.16.3.192/29 = 255.255.255.248, and 172.16.4.0/23 = 255.255.254.0.\n\n**Learn more:** [IP Addressing and Subnetting for New Users](https://www.cisco.com/c/en/us/support/docs/ip/routing-information-protocol-rip/13788-3.html)"} reuse={false} />
