How much data can be encapsulated into a normal sized Ethernet frame before it is sent over the network? 64 to 1518 bytes 32 to 1500 bytes 0 to 1024 bytes 46 to 1500 bytes

46 to 1500 bytes

Host-A has an Ethernet frame to send to Host-B on the same network. Host-A knows the IP address of Host-B but not its MAC address. What message will Host-A send to determine the MAC address of Host B? ARP discovery ARP request ARP reply ARP broadcast

ARP request

The destination MAC address of an Ethernet broadcast in hexadecimal is: 48 one bits 48 F digits 1111.1111.1111 FFFF.FFFF.FFFF

FFFF.FFFF.FFFF

Which destination address is used in an ARP request frame? FFFF.FFFF.FFFF 255.255.255.255 AAAA.AAAA.AAAA 0.0.0.0 the physical address of the destination host

FFFF.FFFF.FFFF

Host-A sends an ARP request and receives an ARP reply from Host-B. What is in the ARP reply that Host-A did not know and needs to communicate with Host-B? Host B's MAC address Host B's IP address Host B's IP and MAC addresses

Host B's MAC address

Host-B receives an ARP request. Host-B will return an ARP Reply if: The IP address in the ARP request matches its own IP address. The MAC address in the ARP request matches its own MAC address. The IP and MAC addresses in the ARP request matches its own IP and MAC addresses.

IP address in the ARP request matches its own IP address

When an Ethernet frame is sent out an interface, the destination MAC address indicates: The MAC address of the device, which is on this network, that will receive the Ethernet frame. The MAC address of the NIC card of a device, which is on this network or another network, that will receive the Ethernet frame. The MAC address of the NIC card that sent the Ethernet frame. The MAC address of the router.

MAC address of the device, which is on this network, that will receive the ethernet frame

Which design layer provides connectivity to devices on an Ethernet LAN? core distribution access physical

access

Which two devices would commonly be found at the access layer of the hierarchical enterprise LAN design model? (Choose two.) Layer 3 device firewall access point Layer 2 switch modular switch

access point layer 2 switch

Which statement is true about broadcast and collision domains? Adding a switch to a network will increase the size of the broadcast domain. The more interfaces a router has the larger the resulting broadcast domain. Adding a router to a network will increase the size of the collision domain. The size of the collision domain can be reduced by adding hubs to a network.

adding a switch to a network will increase the size of the broadcast domain

An ARP request is sent out as: a broadcast, so all devices on the same network will receive it a broadcast, so all devices on the network and other networks will receive it a unicast, so only the device with the proper IP address will receive it a unicast, so only the device with the proper MAC address will receive it

broadcast, so all devices on the same network will receive it

Ethernet switches make their forwarding decision based on what field of the Ethernet frame? SFD (Start Frame Delimiter) Destination MAC address Source MAC address Type/Length FCS

destination MAC address

The process of prepending protocol information with information from another protocol is called: framing encapsulation encoding packetizing

encapsulation

Which term refers to the process of placing one message format inside another message format? segmenting manipulation encapsulation encoding

encapsulation

When a switch receives an Ethernet frame and the destination MAC address of that frame is not in its MAC address table, the switch will: Add the Destination MAC address to the table. Add the Source MAC address to the table. Forward the frame out all ports except in the incoming port. Drop the frame.

forward the frame out all ports except in the incoming port

When an Ethernet switch receives a frame that is broadcast, it will: Forward the frame out all ports except the incoming port Forward the frame out all ports including the incoming port Forward the frame out only ports that need the broadcast Drop the frame

forward the frame out all ports except the incoming port

Which three fields are found in an 802.3 Ethernet frame? (Choose three.) frame check sequence destination physical address source logical address destination logical address media type identifier source physical address

frame check sequence destination physical address source physical address

What is the purpose of the core layer in the Cisco hierarchical network design model? aggregation point for smaller networks high-speed backbone switching flow control between networks network access to end devices

high-speed backbone switching

Which portion of an IP address uniquely identifies that device on that network? physical logical network host

host

The Ethernet protocol is at what layer of the OSI Model? Layer 1 Physical Layer 2 Data Link Layer 3 Network Layer 4 Transport

layer 2 data link

An IP address is considered what type of address: physical logical

logical

Ethernet hubs are considered: cutting-edge obsolete a security device a wireless device

obsolete

What is the purpose of ARP in an IPv4 network? to forward data onward based on the destination IP address to obtain a specific MAC address when an IP address is known to build the MAC address table in a switch from the information that is gathered to forward data onward based on the destination MAC address.

obtain a specific MAC address when an IP address is known

An Ethernet MAC address is considered what type of address: physical logical

physical

Which address does not change when a device is connected to a new network? physical logical

physical

Which Ethernet frame field indicates the beginning of an Ethernet frame? Type/Length Destination MAC Address FCS Preamble and SFD

preamble and SFD

Which network device can serve as a boundary to divide a Layer 2 broadcast domain? Ethernet bridge Ethernet hub router access point

router

Ethernet switches add entries to their MAC address table based on what field of the Ethernet frame? SFD (Start Frame Delimiter) destination MAC address source MAC address Type/Length FCS

source MAC address

What information does an Ethernet switch examine and use to build its address table? source MAC address source IP address destination IP address destination MAC address
