7.5.2 Module Quiz – Ethernet Switching Answers
1. What will a host on an Ethernet network do if it receives a frame with a destination MAC address that does not match its own MAC address?
- It will discard the frame.
- It will forward the frame to the next host.
- It will remove the frame from the media.
- It will strip off the data-link frame to check the destination IP address.
2. What is auto-MDIX?
- a type of Cisco switch
- an Ethernet connector type
- a type of port on a Cisco switch
- a feature that detects Ethernet cable type
3. 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.
4. 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
5. What happens to runt frames received by a Cisco Ethernet switch?
- The frame is dropped.
- The frame is returned to the originating network device.
- The frame is broadcast to all other devices on the same network.
- The frame is sent to the default gateway.
6. What are the two sizes (minimum and maximum) of an Ethernet frame? (Choose two.)
- 56 bytes
- 64 bytes
- 128 bytes
- 1024 bytes
- 1518 bytes
7. What addressing information is recorded by a switch to build its MAC address table?
- the destination Layer 3 address of incoming packets
- the destination Layer 2 address of outgoing frames
- the source Layer 3 address of outgoing packets
- the source Layer 2 address of incoming frames
8. Which two characteristics describe Ethernet technology? (Choose two.)
- It is supported by IEEE 802.3 standards.
- It is supported by IEEE 802.5 standards.
- It typically uses an average of 16 Mb/s for data transfer rates.
- It uses the CSMA/CD access control method.
- It uses a ring topology.
9. What statement describes a characteristic of MAC addresses?
- They must be globally unique.
- They are only routable within the private network.
- They are added as part of a Layer 3 PDU.
- They have a 32-bit binary value.
10. What is the special value assigned to the first 24 bits of a multicast MAC address?
11. Which network device makes forwarding decisions based on the destination MAC address that is contained in the frame?
12. Which network device has the primary function to send data to a specific destination based on the information found in the MAC address table?
13. Which function or operation is performed by the LLC sublayer?
- It performs data encapsulation.
- It communicates with upper protocol layers.
- It is responsible for media access control.
- It adds a header and trailer to a packet to form an OSI Layer 2 PDU.
14. Which statement is true about MAC addresses?
- MAC addresses are implemented by software.
- A NIC only needs a MAC address if connected to a WAN.
- The first three bytes are used by the vendor assigned OUI.
- The ISO is responsible for MAC addresses regulations.
