How does routing influence packet paths in a network?

Imagine you want to send a letter to a friend living in another city. The postal service decides the best roads and stops to deliver your letter efficiently. In computer networks, routing plays a similar role for data packets.

Which statement best explains why routing determines the path a packet takes?

ARouting randomly picks any available path without considering network conditions.
BRouting uses information about network topology and policies to select the best path for packets to reach their destination.
CRouting forces all packets to follow the same fixed path regardless of destination.
DRouting delays packets intentionally to control network traffic.

How does routing adapt when a network link fails?

Suppose a network link between two routers suddenly fails. How does routing help packets still reach their destination?

ARouting protocols detect the failure and update routing tables to use alternative paths automatically.
BRouting stops all packet transmission until the link is fixed manually.
CRouting duplicates packets and sends them through all possible paths simultaneously.
DRouting ignores the failure and continues sending packets through the broken link.

💡 Hint

Think about how GPS recalculates routes when a road is closed.

Why might routing choose a longer path over a shorter one?

Sometimes routing selects a path that is longer in distance but still preferred. Which reason best explains this behavior?

ARouting algorithms always pick the longest path to balance network usage evenly.
BThe longer path is chosen because it uses older hardware.
CThe longer path has less congestion or higher bandwidth, improving overall packet delivery speed.
DRouting cannot measure path length and chooses randomly.

💡 Hint

Consider that the fastest route is not always the shortest distance.

What is the impact of incorrect routing information on packet paths?

If a router has outdated or incorrect routing information, what is the most likely effect on packet delivery?

APackets will be encrypted to avoid routing errors.
BPackets will automatically correct the routing information themselves.
CPackets will be delivered faster because the router ignores the incorrect data.
DPackets may be sent to wrong destinations or get stuck in loops, causing delays or loss.

Think about what happens if a GPS gives wrong directions.
