POST occurred normally.
The boot process was interrupted.
There is not enough RAM or flash on this router.
A full version of the Cisco IOS was located and loaded.
The switch did not locate the Cisco IOS in flash, so it defaulted to ROM.

6. Question

Which two statements are true about using full-duplex Fast Ethernet? (Choose two.)

Performance is improved with bidirectional data flow.
Latency is reduced because the NIC processes frames faster.
Nodes operate in full-duplex with unidirectional data flow.
Performance is improved because the NIC is able to detect collisions.
Full-duplex Fast Ethernet offers 100 percent efficiency in both directions.

7. Question

In which situation would a technician use the show interfaces switch command?

to determine if remote access is enabled
when packets are being dropped from a particular directly attached host
when an end device can reach local devices, but not remote devices
to determine the MAC address of a directly attached network device on a particular interface

8. Question

Refer to the exhibit. A network technician is troubleshooting connectivity issues in an Ethernet network with the command show interfaces fastEthernet 0/0. What conclusion can be drawn based on the partial output in the exhibit?

CCNA2 v6.0 Chapter 5 Exam 004

All hosts on this network communicate in full-duplex mode.
Some workstations might use an incorrect cabling type to connect to the network.
There are collisions in the network that cause frames to occur that are less than 64 bytes in length.
A malfunctioning NIC can cause frames to be transmitted that are longer than the allowed maximum length.

9. Question

Refer to the exhibit. What media issue might exist on the link connected to Fa0/1 based on the show interface command?

CCNA2 v6.0 Chapter 5 Exam 002

The bandwidth parameter on the interface might be too high.
There could be an issue with a faulty NIC.
There could be too much electrical interference and noise on the link.
The cable attaching the host to port Fa0/1 might be too long.
The interface might be configured as half-duplex.

10. Question

If one end of an Ethernet connection is configured for full duplex and the other end of the connection is configured for half duplex, where would late collisions be observed?

on both ends of the connection
on the full-duplex end of the connection
only on serial interfaces
on the half-duplex end of the connection

11. Question

What is one difference between using Telnet or SSH to connect to a network device for management purposes?

Telnet uses UDP as the transport protocol whereas SSH uses TCP.
Telnet does not provide authentication whereas SSH provides authentication.
Telnet supports a host GUI whereas SSH only supports a host CLI.
Telnet sends a username and password in plain text, whereas SSH encrypts the username and password.

12. Question

Refer to the exhibit. The network administrator wants to configure Switch1 to allow SSH connections and prohibit Telnet connections. How should the network administrator change the displayed configuration to satisfy the requirement?

CCNA2 v6.0 Chapter 5 Exam 001

Use SSH version 1.
Reconfigure the RSA key.
Configure SSH on a different line.
Modify the transport input command.

13. Question

What is the effect of using the switchport port-security command?

enables port security on an interface
enables port security globally on the switch
automatically shuts an interface down if applied to a trunk port
detects the first MAC address in a frame that comes into a port and places that MAC address in the MAC address table

14. Question

Where are dynamically learned MAC addresses stored when sticky learning is enabled with the switchport port-security mac-address sticky command?

ROM
RAM
NVRAM
flash

15. Question

A network administrator configures the port security feature on a switch. The security policy specifies that each access port should allow up to two MAC addresses. When the maximum number of MAC addresses is reached, a frame with the unknown source MAC address is dropped and a notification is sent to the syslog server. Which security violation mode should be configured for each access port?

restrict
protect
warning
shutdown

16. Question

Which two statements are true regarding switch port security? (Choose two.)

The three configurable violation modes all log violations via SNMP.
Dynamically learned secure MAC addresses are lost when the switch reboots.
The three configurable violation modes all require user intervention to re-enable ports.
After entering the sticky parameter, only MAC addresses subsequently learned are converted to secure MAC addresses.
If fewer than the maximum number of MAC addresses for a port are configured statically, dynamically learned addresses are added to CAM until the maximum number is reached.

17. Question

Which action will bring an error-disabled switch port back to an operational state?

Remove and reconfigure port security on the interface.
Issue the switchport mode access command on the interface.
Clear the MAC address table on the switch.
Issue the shutdown and then no shutdown interface commands.

18. Question

Refer to the exhibit. Port Fa0/2 has already been configured appropriately. The IP phone and PC work properly. Which switch configuration would be most appropriate for port Fa0/2 if the network administrator has the following goals?

No one is allowed to disconnect the IP phone or the PC and connect some other wired device.
If a different device is connected, port Fa0/2 is shut down.
The switch should automatically detect the MAC address of the IP phone and the PC and add those addresses to the running configuration.
