Practice - 5 Tasks

1fill in blank

easy

Complete the sentence to describe the main metric used by RIP.

Computer Networks

RIP uses [1] as the metric to determine the best path to a destination.

💡 Hint

Common Mistakes

Confusing hop count with bandwidth or delay.

Thinking RIP uses complex metrics like packet loss.

RIP uses hop count as its metric, which counts the number of routers a packet passes through.

2fill in blank

medium

Complete the sentence to explain how often RIP routers send updates.

Computer Networks

RIP routers send their routing updates every [1] seconds to share their routing tables.

A10

B60

C30

D120

Attempts:

💡 Hint

Common Mistakes

Choosing 10 seconds, which is too frequent.

Choosing 60 or 120 seconds, which are longer intervals.

RIP routers multicast their routing tables every 30 seconds to keep routes updated.

3fill in blank

hard

Fix the error in the statement about RIP's maximum hop count.

Computer Networks

The maximum hop count allowed in RIP is [1]; any route with a higher count is considered unreachable.

A15

B10

C16

D20

Attempts:

3 left

💡 Hint

Common Mistakes

Choosing 16 as the maximum hop count instead of 15.

Confusing the unreachable value with the maximum valid hop count.

RIP considers a hop count of 16 as unreachable, so the maximum valid hop count is 15.

4fill in blank

hard

Fill both blanks to complete the description of RIP's routing update method.

Computer Networks

RIP uses [1] routing and sends updates to [2] addresses.

Drag options to blanks, or click blank then click option'

Adistance vector

Blink state

Cbroadcast

Dmulticast

Attempts:

💡 Hint

Common Mistakes

Confusing distance vector with link state.

Thinking RIP uses broadcast instead of multicast.

RIP is a distance vector routing protocol and sends updates using multicast addresses to reduce unnecessary traffic.

5fill in blank

hard

Fill all three blanks to complete the RIP route update rule.

Computer Networks

A router updates its routing table if it receives a route with a [1] hop count, the route is [2] than the current one, and the route comes from a [3] neighbor.

Drag options to blanks, or click blank then click option'

Alower

Bhigher

Cbetter

Ddirect

Attempts:

3 left

💡 Hint

Common Mistakes

Choosing 'higher' hop count instead of 'lower'.

Confusing 'better' with 'higher'.

Not recognizing that routes must come from direct neighbors.

RIP updates routes when it receives a route with a lower hop count, meaning a better route, and the route is from a direct neighbor.
