Quiz No. 1 - Computer Networking 2

What is the first action in the boot sequence when a switch is powered on?

• load the default Cisco IOS software

• load a power-on self-test program

• low-level CPU initialization

• load boot loader software

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

Which protocol adds security to remote connections?

• FTP

• HTTPS

• SSh

• Telnet

Which impact does adding a Layer 2 switch have on a network?

• an increase in the number of dropped frames

• an increase in the size of the broadcast domain

• an increase in the number of network collisions

• an increase in the size of the collision domain

Which characteristic describes cut-through switching?

• Error-free fragments are forwarded, so switching occurs with lower latency.

• Frames are forwarded without any error checking.

• Only outgoing frames are checked for errors.

• Buffering is used to support different Ethernet speeds.

What information is added to the switch table from incoming frames?

• source MAC address and incoming port number

• destination MAC address and incoming port number

• source IP address and incoming port number

• destination IP address and incoming port number

Refer to the exhibit. How many broadcast domains are displayed?

What type of Ethernet cable would be used to connect one switch to another switch when neither switch supports the auto-MDIX feature?

• Straight-through

• Crossover

• Coaxial

• Rollover

Which statement is true about broadcast and collision domains?

• Adding a router to a network will increase the size of the collision domain.

• The size of the collision domain can be reduced by adding hubs to a network.

• The more interfaces a router has the larger the resulting broadcast domain.

• Adding a switch to a network will increase the size of the broadcast domain.

What will a Cisco LAN switch do if it receives an incoming frame and the destination MAC address is not listed in the MAC address table?

• Drop the frame.

• Send the frame to the default gateway address.

• Use ARP to resolve the port that is related to the frame.

• Forward the frame out all ports except the port where the frame is received.
