Deck 7: Configuring and Verifying Switch Interfaces

Question 1

If a Cisco Gigabit Ethernet port is connected to a device that does not support IEEE autonegotiation, and the interface speed cannot be sensed, what speed is the interface defaulted into?

A) 1 Gbps
B) 10 Mbps
C) 100 Mbps
D) None; the port is shut down

Answer 1

10 Mbps

Question 2

$\begin{array}{lccc}\mathrm{Ea} 0 / 1 &\text { connected }& 1 &\text { half }&\text { a-100 } \\\text {10 / 100 BaseTX}\\\mathrm{Fa} 0 / 2 &\text { notconnect} & 1 &\text { auto} & \text {auto} \\\text {10/100 BaseTX}\\\mathrm{Fa} 0 / 3 &\text { notconnect }& 1 &\text { auto} &\text { auto }\\10 / 100 \mathrm{BaseTX} \\ \mathrm{Fa} 0 / 4& \text {notconnect}& 1 &\text { auto }& \text {auto} \\10/100BaseTX\\\mathrm{Fa} 0 / 5 & \text {notconnect }& 1 &\text { auto} & \text {auto} \\ 10 / 100 \mathrm{BaseTX} \end{array}$

Refer to the figure. From the output shown from the show interface status command, what can be determined about how speed and duplex were assigned to interface F0/1?

A) Duplex was autonegotiated.
B) Speed was not autonegotiated.
C) Duplex was not autonegotiated.
D) Speed was autonegotiated.

Answer 2

Duplex was not autonegotiated.
Speed was autonegotiated.

Question 3

When using the no speed command on an interface, what is the resulting change made?

A) The speed defaults to the lowest possible value.
B) The speed setting is no longer recorded for the interface.
C) The speed setting defaults to its automatic configuration.
D) The speed for the interface is set to 0, disabling it.

Answer 3

The speed setting defaults to its automatic configuration.

Question 4

What does it mean when an interface does NOT display configuration settings when using the show running-config and show startup-config commands?

A) It means the configuration is running with default settings.
B) It means the interface is not active.
C) It means the interface is configured the same as the previous entry.
D) It means the interface is configured the same as the following entry.

Question 5

Which of the following is the most essential fact that allows the IEEE autonegotiation protocol to function?

A) Cisco meets the IEEE standard for the protocol.
B) Wiring pinouts are common for 10BASE-T, 100BASE-T, and 1000BASE-T.
C) Any Ethernet device can sense the speed of a connection.
D) Cisco switch logic can determine speed and duplex for a connection.

Question 6

Which of the following will disable autonegotiation for an interface on a Cisco switch?

A) Setting the speed setting for the interface
B) Setting the duplex setting for the interface
C) Setting both the speed and duplex settings for the interface
D) Autonegotiation is disabled by default

Question 7

Which of the following will occur if the speed setting cannot be sensed in a Cisco switch?

A) The speed will default to 1 Mbps.
B) The speed will default to the lowest setting available.
C) The speed will default to the highest speed available.
D) The speed will default to the setting reported from the other end of the interface.
