Which statement describes the port speed LED on the Cisco Catalyst 2960 switch?
If the LED is green, the port is operating at 100 Mb/s.
If the LED is off, the port is not operating.
F the LED is blinking green, the port is operating at 10 Mb/s.
Which command is used to set the BOOT environment variable that defines where to find the IOS image file on a switch?
Config-register
Boot system
Boot loader
Confreg
What is a function of the switch boot loader?
To speed up the boot process
To provide security for the vulnerable state when the switch is booting
To control how much RAM is available to the switch during the boot process
To provide an environment to operate in when the switch operating system cannot be found
Which interface is the default location that would contain the IP address used to manage a 24-port Ethernet switch?
VLAN 1
Fa0/0
Fa0/1
Interface connected to the default gateway
A production switch is reloaded and finishes with a Switch> prompt. What two facts can be determined? (Choose two.)
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.*
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.
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?
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.
Refer to the exhibit. What media issue might exist on the link connected to Fa0/1 based on the show interface command?
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.
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
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.
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?
Use SSH version 1.
Reconfigure the RSA key.
Configure SSH on a different line.
Modify the transport input command.
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
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
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
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.*
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.
The following words are displayed: ATC_S2# show port-security interface fastethernet 0/3 Port Security : Enabled Port Status : Secure-up Violation Mode : Shutdown Aging Time : 0 mins Aging Type : Absolute
The port has been shut down.
The port has two attached devices.
The port violation mode is the default for any port that has port security enabled.*
The port has the maximum number of MAC addresses that is supported by a Layer 2 switch port which is configured for port security.
Refer to the exhibit. Which event will take place if there is a port security violation on switch S1 interface Fa0/1?
A notification is sent.
A syslog message is logged.
Packets with unknown source addresses will be dropped.
The interface will go into error-disabled state.
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?
Packets with unknown source addresses will be dropped.
A syslog message is logged.
The interface will go into error-disabled state.
A notification is sent.
