Exam Chapter 5 Questions and Answers CCNA 2 V6.0

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?

¡ Correcto ! ¡ Incorrecto !

Full-duplex communications do not produce collisions. However, collisions often occur in half-duplex operations. When a connection has two different duplex configurations, the half-duplex end will experience late collisions. Collisions are found on Ethernet networks. Serial interfaces use technologies other than Ethernet.

Open the PT Activity. Perform the tasks in the activity instructions and then answer the question. Which event will take place if there is a port security violation on switch S1 interface Fa0/1?

¡ Correcto ! ¡ Incorrecto !

The violation mode can be viewed by issuing the show port-security interface command. Interface FastEthernet 0/1 is configured with the violation mode of protect. If there is a violation, interface FastEthernet 0/1 will drop packets with unknown MAC addresses.

Which interface is the default location that would contain the IP address used to manage a 24-port Ethernet switch?

¡ Correcto ! ¡ Incorrecto !

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?

¡ Correcto ! ¡ Incorrecto !

The partial output shows that there are 50 giants (frames longer than the allowed maximum) that were injected into the network, possibly by a malfunctioning NIC. This conclusion can be drawn because there are only 25 collisions, so not all the 50 giants are the result of a collision. Also, because there 25 collisions, it is most likely that not all hosts are using full-duplex mode (otherwise there would not be any collisions). There should be no cabling issues since the CRC error value is 0. There are 0 runts, so the collisions have not caused malformed frames to occur that are shorter than 64 bytes in length .

Match the step to each switch boot sequence description. (Not all options are used.)

¡ Correcto ! ¡ Incorrecto !

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

¡ Correcto ! ¡ Incorrecto !

Escalating CRC errors usually means that the data is being modified during transmission from the host to the switch. This is often caused by high levels of electromagnetic interference on the link.

Identify the steps needed to configure a switch for SSH. The answer order does not matter. (Not all options are used.)

¡ Correcto ! ¡ Incorrecto !

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

¡ Correcto ! ¡ Incorrecto !

Port security cannot be enabled globally. All active switch ports should be manually secured using the switchport port-security command, which allows the administrator to control the number of valid MAC addresses allowed to access the port. This command does not specify what action will be taken if a violation occurs, nor does it change the process of populating the MAC address table.

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

¡ Correcto ! ¡ Incorrecto !

The default mode for a port security violation is to shut down the port so the switchport port-security violation command is not necessary. The switchport port-security command must be entered with no additional options to enable port security for the port. Then, additional port security options can be added.

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

¡ Correcto ! ¡ Incorrecto !

The show interfaces command is useful to detect media errors, to see if packets are being sent and received, and to determine if any runts, giants, CRCs, interface resets, or other errors have occurred. Problems with reachability to a remote network would likely be caused by a misconfigured default gateway or other routing issue, not a switch issue. The show mac address-table command shows the MAC address of a directly attached device.

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?

¡ Correcto ! ¡ Incorrecto !

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?

¡ Correcto ! ¡ Incorrecto !

In port security implementation, an interface can be configured for one of three violation modes:
Protect – a port security violation causes the interface to drop packets with unknown source addresses and no notification is sent that a security violation has occurred.
Restrict – a port security violation causes the interface to drop packets with unknown source addresses and to send a notification that a security violation has occurred.
Shutdown – a port security violation causes the interface to immediately become error-disabled and turns off the port LED. No notification is sent that a security violation has occurred.

Refer to the exhibit. What can be determined about port security from the information that is shown?

¡ Correcto ! ¡ Incorrecto !

The Port Security line simply shows a state of Enabled if the switchport port-security command (with no options) has been entered for a particular switch port. If a port security violation had occurred, a different error message appears such as Secure-shutdown. The maximum number of MAC addresses supported is 50. The Maximum MAC Addresses line is used to show how many MAC addresses can be learned (2 in this case). The Sticky MAC Addresses line shows that only one device has been attached and learned automatically by the switch. This configuration could be used when a port is shared by two cubicle-sharing personnel who bring in separate laptops.

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

¡ Correcto ! ¡ Incorrecto !

When MAC addresses are automatically learned by using the sticky command option, the learned MAC addresses are added to the running configuration, which is stored in RAM.

Match the link state to the interface and protocol status. (Not all options are used.)

¡ Correcto ! ¡ Incorrecto !

What is a function of the switch boot loader?

¡ Correcto ! ¡ Incorrecto !

The switch boot loader environment is presented when the switch cannot locate a valid operating system. The boot loader environment provides a few basic commands that allows a network administrator to reload the operating system or provide an alternate location of the operating system.

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

¡ Correcto ! ¡ Incorrecto !

When a violation occurs on a switch port that is configured for port security with the shutdown violation action, it is put into the err-disabled state. It can be brought back up by shutting down the interface and then issuing the no shutdown command.

Refer to the exhibit. Which event will take place if there is a port security violation on switch S1 interface Fa0/1?

¡ Correcto ! ¡ Incorrecto !

Interface FastEthernet 0/1 is configured with the violation mode of protect. If there is a violation, interface FastEthernet 0/1 will drop packets with unknown MAC addresses.

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

Which command is used to set the BOOT environment variable that defines where to find the IOS image file on a switch?

¡ Correcto ! ¡ Incorrecto !

The boot system command is used to set the BOOT environment variable. The config-register and confreg commands are used to set the configuration register. The boot loader command supports commands to format the flash file system, reinstall the operating system software, and recover from a lost or forgotten password.

A production switch is reloaded and finishes with a Switch> prompt. What two facts can be determined? (Choose two.)

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

¡ Correcto ! ¡ Incorrecto !

SSH provides security for remote management connections to a network device. SSH does so through encryption for session authentication (username and password) as well as for data transmission. Telnet sends a username and password in plain text, which can be targeted to obtain the username and password through data capture. Both Telnet and SSH use TCP, support authentication, and connect to hosts in CLI.

Which statement describes the port speed LED on the Cisco Catalyst 2960 switch?

¡ Correcto ! ¡ Incorrecto !

The port speed LED indicates that the port speed mode is selected. When selected, the port LEDs will display colors with different meanings. If the LED is off, the port is operating at 10 Mb/s. If the LED is green, the port is operating at 100 Mb/s. If the LED is blinking green, the port is operating at 1000 Mb/s.
