- encourages vendors to create proprietary protocols
- provides consistent interconnections across networks
- ensures that communications work best in a single-vendor environment
- simplifies new product development
Which two items are included in a network logical map? (Choose two.)
- naming scheme
- IP addressing scheme
- length of cable runs
- physical location of networking devices

What is a reason for disabling simple file sharing?
- It enables the user to map a remote resource with a local drive.
- It enables the user to share all files with all users and groups.
- It enables the user to share printers.
- It enables the user to set more specific security access levels.
Which address does an NIC use when deciding whether to accept a frame?
- source IP address
- source MAC address
- destination IP address
- destination MAC address
- source Ethernet address
If the default gateway is configured incorrectly on the host, what is the impact on communications?
- The host is unable to communicate on the local network.
- The host can communicate with other hosts on the local network, but is unable to communicate with hosts on remote networks.
- The host can communicate with other hosts on remote networks, but is unable to communicate with hosts on the local network.
- There is no impact on communications.
Refer to the graphic. What does the router do after it determines that a data packet from Network 1 should be forwarded to Network 2?
- It sends the data packet as it was received.
- It reassembles the frame with different MAC addresses than the original frame.
- It reassembles the data packet with different IP addresses than the original data packet.
- It reassembles both the packet and the frame with different destination IP and MAC addresses
What is the function of the FCS field in an Ethernet frame?
- detects transmission errors
- provides timing for transmission
- contains the start of frame delimiter
- indicates which protocol will receive the frame
Host A needs to learn the MAC address of Host B, which is on the same LAN segment. A message has been sent to all the hosts on the segment asking for the MAC address of Host B. Host B responds with its MAC address and all other hosts disregard the request. What protocol was used in this scenario?
- ARP
- DHCP
- DNS
- WINS
What is a benefit of having a router within the distribution layer?
- prevents collisions on a local network
- keeps broadcasts contained within a local network
- controls which hosts have access to the network
- controls host-to-host traffic within a single local network
Which term is used to describe the process of placing one message format into another format so that the message can be delivered across the appropriate medium?
- flow control
- encapsulation
- encoding
- multicasting
- access method
Which table does a router use to make decisions about the interface through which a data packet is to be sent?
- ARP table
- routing table
- network table
- forwarding table
Which two networking devices are used to connect hosts to the access layer? (Choose two.)
- router
- hub
- switch
- server
- computer
What does the 100 mean when referencing the 100BASE-T Ethernet standard?
- type of cable used
- type of data transmission
- speed of transmission
- type of connector required
- maximum length of cable allowed
What device is typically used as the default gateway for a computer?
- a server hosted by the ISP
- the router interface closest to the computer
- a server managed by a central IT department
- the switch interface that connects to the compute
Refer to the graphic. Five PCs are connected through a hub. If host H1 wants to reply to a message from host H2, which statement is true?
- H1 sends a unicast message to H2, but the hub forwards it to all devices.
- H1 sends a unicast message to H2, and the hub forwards it directly to H2.
- H1 sends a broadcast message to H2, and the hub forwards it to all devices.
- H1 sends a multicast message to H2, and the hub forwards it directly to H2.
Which type of address is used in an Ethernet frame header?
- logical addresses only
- IP addresses only
- MAC addresses only
- broadcast addresses only
A switch receives a frame with a destination MAC address that is currently not in the MAC table. What action does the switch perform?
- It drops the frame.
- It sends out an ARP request looking for the MAC address
- It floods the frame out of all active ports, except the origination port.
- It returns the frame to the sender.
Which device accepts a message on one port and always forwards the message to all other ports?
- modem
- switch
- router
- hub
If a router receives a packet that it does not know how to forward, what type of route must be configured on the router to prevent the router from dropping it?
- dynamic route
- default route
- destination route
- default destination
An integrated router can normally perform the functions of which two other network devices? (Choose two.)
- NIC
- switch
- e-mail server
- application server
- wireless access point
What is the purpose of logical addresses in an IP network?
- They identify a specific NIC on a host device.
- They are used to determine which host device accepts the frame.
- They provide vendor-specific information about the host.
- They are used to determine the network that the host is located on.
- They are used by switches to make forwarding decisions.
