Cisco 1, Module 7

Which two characteristics describe Ethernet technology? (Choose two.)

• It is supported by IEEE 802.5 standards.

• It uses unique MAC addresses to ensure that data is sent to the appropriate destination.

• It uses a ring topology.

• It is supported by IEEE 802.3 standards.

• It typically uses an average of 16 Mbps for data transfer rates

What statement describes a characteristic of MAC addresses?

• They are added as part of a Layer 3 PDU.

• They are only routable within the private network.

• They must be globally unique.

• They have a 32-bit binary value.

What is auto-MDIX? 

• a type of Cisco switch

• an Ethernet connector type

• a feature to automatically determine speed and duplex

• a feature that detects Ethernet cable type

What type of address is 01-00-5E-0A-00-02?

• an address that reaches a specific host

• an address that reaches every host inside a local subnet

• an address that reaches every host in the network

• an address that reaches a specific group of hosts

Which statement is true about MAC addresses?

• A NIC only needs a MAC address if connected to a WAN.

• The ISO is responsible for MAC addresses regulations.

• The first three bytes are used by the vendor assigned OUI.

• MAC addresses are implemented by software.

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

• 128 bytes

• 1024 bytes

• 1518 bytes

• 56 bytes

• 64 bytes

Which two functions or operations are performed by the MAC sublayer? (Choose two.)

• It adds control information to network protocol layer data.

• It performs the function of NIC driver software.

• It handles communication between upper and lower layers.

• It is responsible for Media Access Control.

• It adds a header and trailer to form an OSI Layer 2 PDU.

Which network device makes forwarding decisions based on the destination MAC address that is contained in the frame?

• router

• switch

• hub

• repeater

Which network device has the primary function to send data to a specific destination based on the information found in the MAC address table?

• hub

• modem

• router

• switch

Which function or operation is performed by the LLC sublayer?

• 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.

• It performs data encapsulation.
