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

Boot System

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 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.

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

Issue the shutdown command and then the no shutdown command

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. The switch did not locate the Cisco IOS in flash, so it defaulted to ROM.

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.*

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

RAM

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

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

Telnet sends a username and password in plain text, whereas SSH encrypts the username and password.

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

VLAN 1

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

enables port security on an interface

What is the missing command on S1?

ip address 192.168.99.2 255.255.255.0

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?

o) the half-duplex end of the connection

What is a function of the switch boot loader?

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?

when packets are being dropped from a particular directly attached host
