CCNA 1 R&S Introduction to Networks Chapter 5 QUIZ
1 Fill in the blank.
The Ethernet “_________” sublayer is responsible for communicating directly with the physical layer.
2 Which two functions or operations are performed by the MAC sublayer? (Choose two.)
It is responsible for Media Access Control.*
It performs the function of NIC driver software.
It adds a header and trailer to form an OSI Layer 2 PDU.*
It handles communication between upper and lower layers.
It adds control information to network protocol layer data.
3 What is a characteristic of a contention-based access method?
It processes more overhead than the controlled access methods do.
It has mechanisms to track the turns to access the media.
It is a nondeterministic method.*
It scales very well under heavy media use.
4 Fill in the blank.
On Ethernet networks, the hexadecimal address FF-FF-FF-FF-FF-FF represents the “______” MAC address.
5 Fill in the blank.
A collision fragment, also known as a “_________” frame, is a frame of fewer than 64 bytes in length.
6 What type of address is 01-00-5E-0A-00-02?
an address that reaches every host inside a local subnet
an address that reaches one specific host*
an address that reaches every host in the network
an address that reaches a specific group of hosts
Refer to the exhibit. What is the destination MAC address of the Ethernet frame as it leaves the web server if the final destination is PC1?
8 Which destination address is used in an ARP request frame?
the physical address of the destination host
Refer to the exhibit. PC1 issues an ARP request because it needs to send a packet to PC3. In this scenario, what will happen next?
RT1 will forward the ARP request to PC3.
RT1 will send an ARP reply with its own Fa0/0 MAC address.*
RT1 will send an ARP reply with the PC3 MAC address.
SW1 will send an ARP reply with its Fa0/1 MAC address.
RT1 will send an ARP reply with its own Fa0/1 MAC address.
Refer to the graphic. H2 has sent a broadcast message to all of the hosts. If host H1 wants to reply to the broadcast message, which statement is true?
H1 sends a unicast message to H2, but the switch forwards it to all devices.
H1 sends a unicast message to H2, and the switch forwards it directly to H2.*
H1 sends a broadcast message to H2, and the switch forwards it to all devices.
H1 sends a multicast message to H2, and the switch forwards it directly to H2.
11 Which action is taken by a Layer 2 switch when it receives a Layer 2 broadcast frame?
It drops the frame.
It sends the frame to all ports except the port on which it received the frame.*
It sends the frame to all ports that are registered to forward broadcasts.
It sends the frame to all ports.
12 Which term defines the processing capabilities of a switch by rating how much data can be processed per second?
13 Which interface command must be entered in a Layer 3 switch before an IPv4 address can be assigned to that interface?
