LAN - Chapter 2 Quiz

Which interface is the default location that would contain the IP address used to manage a 24-port Ethernet switch?
1. VLAN 1
2. Fa0/0
3. Fa0/1
4. interface connected to the default gateway
5. VLAN99
Which two statements are true about using full-duplex Fast Ethernet? (Choose two.)
1. Performance is improved with bidirectional data flow.
2. Latency is reduced because the NIC processes frames faster.
3. Nodes operate in full-duplex with unidirectional data flow.
4. Performance is improved because the NIC is able to detect collisions.
5. Full-duplex Fast Ethernet offers 100 percent efficiency in both directions.
What is a function of the switch boot loader?
1. to speed up the boot process
2. to provide security for the vulnerable state when the switch is booting
3. to control how much RAM is available to the switch during the boot process
4. to provide an environment to operate in when the switch operating system cannot be found
In which situation would a technician use the show interfaces switch command?
1. to determine if remote access is enabled
2. when packets are being dropped from a particular directly attached host
3. when an end device can reach local devices, but not remote devices
4. to determine the MAC address of a directly attached network device on a particular interface
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?
1. All hosts on this network communicate in full-duplex mode.
2. Some workstations might use an incorrect cabling type to connect to the network.
3. There are collisions in the network that cause frames to occur that are less than 64 bytes in length.
4. A malfunctioning NIC can cause frames to be transmitted that are longer than the allowed maximum length.
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?
1. Use SSH version 1.
2. Reconfigure the RSA key.
3. Configure SSH on a different line.
4. Modify the transport input command.
What is one difference between using Telnet or SSH to connect to a network device for management purposes?
1. Telnet uses UDP as the transport protocol whereas SSH uses TCP.
2. Telnet does not provide authentication whereas SSH provides authentication.
3. Telnet supports a host GUI whereas SSH only supports a host CLI.
4. Telnet sends a username and password in plain text, whereas SSH encrypts the username and password.
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?
1. CAM table overflow
2. MAC address flooding
3. DHCP starvation
4. DHCP spoofing
Which method would mitigate a MAC address flooding attack?
1. increasing the size of the CAM table
2. configuring port security
3. using ACLs to filter broadcast traffic on the switch
4. increasing the speed of switch ports
Which action will bring an error-disabled switch port back to an operational state?
1. Remove and reconfigure port security on the interface.
2. Issue the switchport mode access command on the interface.
3. Clear the MAC address table on the switch.
4. Issue the shutdown and then no shutdown interface commands.
