CCNA 1/Module 10: Routing Fundamentals and Subnets


Curriculum
Question
Answer
1. What is a set of rules that
determines how computer
communicate with each other across
networks?
Protocol
2. What does a routed protocol allow
the router to forward?
allows the router to forward data
between nodes on different networks
3. Which protocol requires only a
network number because it uses the
host's MAC address for the host
number?
IPX
4. What is obtained by ANDing?
The network address
10.1.1
5. Why are network masks used?
To allow groups of sequential IP
addresses to be treated as a single
unit.
6. What protocol is connectionless,
unreliable, and is considered a best-
effort delivery method?
IP / Internet Protocol
10.1.2
7. What is another term for packets?
Datagrams
8. What are Layer 2 data units used
for?
To determine local addressing.

frame is received at a router
interface?
The destination MAC address
10.1.3
10. What does a router do with a frame
that is NOT addressed to the router
interface or is NOT a broadcast?
The frame is discarded
11. What does HELN stand for?
IP header length
10.1.5
12. How many bits of an IP packets are
reserved for the source and
destination IP address?
32 bits each
13. What Layer does routing?
Layer 3- Network Layer
14. What information is used to
determine where to send packets?
Routing tables
15. What are values used in determining
the advantage of one route over
another?
Routing metrics

agreement by all routers on
available routes?
Convergence
10.2.6
32. What routing metric is determined by
the number of routers that a packet
must travel through before reaching
its destination?
