Which type of cable does a network administrator need to connect a PC to a switch to recover it after the Cisco IOS software fails to load?

Which two basic functions are performed by network security tools? (Choose two.)

While troubleshooting a connectivity problem, a network administrator notices that a switch port status LED is alternating between green and amber. What could this LED indicate?

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?

Open the PT Activity. Perform the tasks in the activity instructions and then answer the question.
Fill in the blank.

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

In which type of attack does a malicious node request all available IP addresses in the address pool of a DHCP server in order to prevent legitimate hosts from obtaining network access?​

Which protocol or service sends broadcasts containing the Cisco IOS software version of the sending device, and the packets of which can be captured by malicious hosts on the network?

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

The network administrator enters the following commands on a Cisco switch:

Switch(config)# interface vlan1
Switch(config-if)# ip address 192.168.1.2 255.255.255.0
Switch(config-if)# no shutdown

What is the effect of entering these commands?

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.

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

Which method would mitigate a MAC address flooding attack?

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

Fill in the blank.

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

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

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

Match the step to each switch boot sequence description.

Fill in the blank.

Refer to the exhibit. Which S1 switch port interface or interfaces should be configured with the ip dhcp snooping trust command if best practices are implemented?

What impact does the use of the mdix auto configuration command have on an Ethernet interface on a switch?

Which command displays information about the auto-MDIX setting for a specific interface?​

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