MODULE 7 NETWORKING

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.

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

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.

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

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

What are the two sizes (minimum and maximum) of an Ethernet frame? (Choose two.)

• 56 bytes

• 64 bytes

• 128 bytes

• 1024 bytes

• 1518 bytes

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

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.

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.

What is the special value assigned to the first 24 bits of a multicast MAC address?

• 01-5E-00

• FF-00-5E

• FF-FF-FF

• 01-00-5E
