Objective 1.1

200-301

Explain the role and function of network components.

Objective 1.1 sits in Network Fundamentals, which carries 20% of the CCNA exam. The questions below are original, written from the official objective title above, and each explanation cites the Cisco page it rests on.

A worked example

Shown solved, with the whole explanation open: this is what every question here carries.

1-1Network Fundamentals

Two Ethernet segments are joined by a device that switches frames at the link layer. What does that imply for IP addressing on the two segments?

Each segment requires a separate IP subnetA routed boundary would demand this, which is the case when the joining device forwards on the IP header instead.
Traffic between them needs a default gatewayA gateway is consulted for destinations outside the local prefix, and every host here is inside it.
Both segments belong to a single IP subnetCorrect · your answerCorrect. Link layer relaying keeps one prefix stretched across both segments.
The device rewrites each frame's destinationRewriting addresses describes network address translation, a router function rather than transparent bridging.

Correct.

Checked against datatracker.ietf.org, August 2026

Concept

A device that relays frames without reading the network header does not create a boundary at the IP layer. Address planning follows the layer at which a device makes its decision, not the count of physical segments.

Why C

Link layer relaying leaves the IP header untouched, so hosts on either side reach each other through address resolution alone. One prefix therefore spans both cable runs, and nothing terminates it in the middle.

Sample question 1 of 3

1-1Network Fundamentals

A router receives a datagram addressed to a host on a network it is not attached to. What does the route database supply for that datagram?

Sample question 2 of 3

1-1Network Fundamentals

An access point is managed by a controller and local forwarding is turned off on its datapath. A client sends traffic to a printer on the same access point. Where do the frames go?

Sample question 3 of 3

1-1Network Fundamentals

A stateful firewall permits established and related traffic and drops the rest. An FTP transfer works even though no rule names the data connection. What allows it through?
