5 Which statement is true regarding routing metrics?
All routing protocols use the same metrics
EIGRP uses bandwidth as its only metric
Routers compare metrics to determine the best route
enOnene The larger metric generally represents the better path
Trang 4Which path will be used to transmit the data packets between PC1 and PC22
The packets will travel via R2-R1
The packets will travel via R2-R3
The traffic will be load-balanced between two paths — via R2-R1 and via R2-R3
The packets will travel via R2-R3, and the other path via R2-R1 will be retained as the backup path

31 What does RIP use to reduce convergence time in a larger network?
It uses multicast instead of broadcast to send routing updates
It reduces the update timer to 15 seconds if there are more than 10 routes
It uses triggered updates to announce network changes if they happen in between the periodic updates
eonenene It uses random pings to detect if a pathway is down and therefore is preemptive on finding networks that are down
