Networking module 7 study guide

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?

00-60-2F-3A-07-CC

What type of communication rule would best describe CSMA/CD

Access method

Which statement is true about the CSMA/CD access method that is used in Ethernet?

All network devices must listen before transmitting

Which statement describes an extended star topology?

End devices connect to a central intermediate device, which in turn connects to other central intermediate devices?

Which destination address is used in an ARP request frame

FFFF.FFFF.FFFF

What are two examples of the cut-through switching method? (Choose two.)

Fast-forward switching and fragment-free switching

What property of ARP allows hosts on a LAN to send traffic to remote networks?

Local hosts learn the MAC address of the default gateway

A network team is comparing physical WAN topologies for connecting remote sites to a headquarters building. Which topology provides high availability and connects some, but not all remote sites?

Partial mesh

What action will occur if a switch receives a frame with the destination MAC address FF:FF:FF:FF:FF:FF?

The switch forwards it out all ports except the ingress port

Which statement describes the treatment of ARP requests on the local link?

They are received and processed by every device on the local network

Which media communication type does not require media arbitration in the data link layer?

full-duplex

Which frame forwarding method receives the entire frame and performs a CRC check to detect errors before forwarding the frame?

store-and-forward switching

What is the function of the CRC value that is found in the FCS field of a frame?

to verify the integrity of the received frame

What is a characteristic of the LLC sublayer?

It places information in the frame about the Layer 3 protocols

What is contained in the trailer of a data -link frame?

error detection

Which advantage does the store-and-forward switching method have compare wit the cut-through switching method?

frame error checking

Which two fields or features does Ethernet examine to determine if a received frame is passed to the data link layer or discarded by the NIC? (Choose two.)

1.) Frame Check Sequence 2.) Destination MAC address

What are three ways that media access control is used in networking? (Choose two.)

1.) Media access control provides placement of data frames onto the media 2.) Data link layer protocols define the rules for access to different media

A network administrator is connecting two modern switches using a straight-through cable. The switches are new and have never been configured. Which three statements are correct about the final result of the connection? (Choose three.)

1.) The link between the switches will work at the fastest speed that is supported by both switches 2.) The link between switches will work as full-duplex 3.) the auto-MDIX feature will configure the interfaces eliminating the need for a crossover cable?

What three items are contained in an Ethernet header and trailer? (Choose three.)

1.) source MAC address 2.) destination MAC address 3.) error-checking information

What are two actions performed by a Cisco switch? (Choose two.)

1.) using the source MAC addresses of frames to build and maintain a MAV address table 2.) utilizing the MAC address table to forward frames via the destination MAC address

Where are IPv4 address to Layer 2 Ethernet address mappings maintained on a host computer?

ARP cache

What statement describes the function of the Address Resolution Protocol?

ARP is used to discover the MAC address of any host on the local network

What action will occur if a switch receives a frame and does have the source MAC address in the MAC table?

The switch refreshes the timer on that entry

What is the auto-MDIX feature on a switch?

the automatic configuration of an interface for a straight-through or a crossover Ethernet cable connection
