chapter 5 exam

port-based

On a Cisco switch,----------memory buffering is used to buffer frames in queues linked to specific incoming and outgoing ports.

PC2 will send an ARP reply with its MAC address.

PC1 issues an ARP request because it needs to send a packet to PC2. In this scenario, what will happen next?

The switch will forward the frame to all ports except port 4.

PC1(port 4) has sent a frame addressed to PC3. What will the switch do with the frame?

Layer 3 address to a Layer 2 address

The ARP table in a switch maps which two types of address together?

the source Layer 2 address of incoming frames

What addressing information is recorded by a switch to build its MAC address table?

Min-64 bytes Max- 1518 bytes

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

On large networks with low bandwidth, multiple ARP broadcasts could cause data communication delays. Network attackers could manipulate MAC address and IP address mappings in ARP messages with the intent of intercepting network traffic.

What are two potential network problems that can result from ARP operation? (Choose two.)

The frame is dropped.

What happens to runt frames received by a Cisco Ethernet switch?

a feature that detects Ethernet cable type

What is auto-MDIX?

It defines the most common LAN type in the world.

What statement describes Ethernet?

They must be globally unique.

What statement describes a characteristic of MAC addresses?

the default gateway.

When a device is sending data to another device on a remote network, the Ethernet frame is sent to the MAC address of ------------

FFFF.FFFF.FFFF

Which destination address is used in an ARP request frame?

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

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

The first three bytes are used by the vendor assigned OUI

Which statement is true about MAC addresses?

store-and-forward

Which switching method uses the CRC value in a frame?

implemented in software. The data link layer uses LLC to communicate with the upper layers of the protocol suite.

Which two statements describe features or functions of the logical link control sublayer in Ethernet standards? (Choose two.)

A collision fragment

a RUNT frame, is a frame of fewer than 64 bytes in length.

spoofing

a technique that is used to send fake ARP messages to other hosts in the LAN. The aim is to associate IP addresses to the wrong MAC addresses.

cut-through

has low latency forward runt frames begin forwarding when the destination address is recieved
