CCNA 1 Chapter 3 Exam Answers
- Refer to the exhibit. HostA is attempting to contact ServerB. Which two statements correctly describe the addressing that HostA will generate in the process? (Choose two.)
- A packet with the destination IP address of RouterB.
- A frame with the destination MAC address of SwitchA.
- A packet with the destination IP address of RouterA.
- A frame with the destination MAC address of RouterA. *
- A packet with the destination IP address of ServerB.*
- A frame with the destination MAC address of ServerB.
- Which address does a NIC use when deciding whether to accept a frame?
- source IP address
- source MAC address
- destination IP address
- destination MAC address*
- source Ethernet address
- At which layer of the OSI model would a logical address be encapsulated?
- physical layer
- data link layer
- network layer*
- transport layer
- Which PDU format is used when bits are received from the network medium by the NIC of a host?
- file
- frame*
- packet
- segment
- What process is used to place one message inside another message for transfer from the source to the destination?
- access control
- decoding
- encapsulation*
- flow control
- A web client is sending a request for a webpage to a web server. From the perspective of the client, what is the correct order of the protocol stack that is used to prepare the request for transmission?
- HTTP, IP, TCP, Ethernet
- HTTP, TCP, IP, Ethernet*
- Ethernet, TCP, IP, HTTP
- Ethernet, IP, TCP, HTTP
- Which statement is correct about network protocols?
- Network protocols define the type of hardware that is used and how it is mounted in racks.
- They define how messages are exchanged between the source and the destination.*
- They all function in the network access layer of TCP/IP.
- They are only required for exchange of messages between devices on remote networks.
- What method can be used by two computers to ensure that packets are not dropped because too much data is being sent too quickly?
- encapsulation
- flow control*
- access method
- response timeout
- What type of communication will send a message to all devices on a local area network?
- broadcast*
- multicast
- unicast
- allcast
- What three application layer protocols are part of the TCP/IP protocol suite? (Choose three.)
- ARP
- DHCP *
- DNS *
- FTP*
- NAT
- PPP
- What are proprietary protocols?
- protocols developed by private organizations to operate on any vendor hardware
- protocols that can be freely used by any organization or vendor
- protocols developed by organizations who have control over their definition and operation*
- a collection of protocols known as the TCP/IP protocol suite
- What is an advantage of network devices using open standard protocols?
- Network communications is confined to data transfers between devices from the same vendor.
- A client host and a server running different operating systems can successfully exchange data.*
- Internet access can be controlled by a single ISP in each market.
- Competition and innovation are limited to specific types of products.
- Refer to the exhibit. If Host1 were to transfer a file to the server, what layers of the TCP/IP model would be used?
- only application and Internet layers
- only Internet and network access layers
- only application, Internet, and network access layers
- application, transport, Internet, and network access layers*
- only application, transport, network, data link, and physical layers
- application, session, transport, network, data link, and physical layers
- Which three layers of the OSI model are comparable in function to the application layer of the TCP/IP model? (Choose three.)
- application *
- presentation *
- session*
- transport
- data link
- physical
- network
- Which PDU is processed when a host computer is de-encapsulating a message at the transport layer of the TCP/IP model?
- bits
- frame
- packet
- segment*
- What will happen if the default gateway address is incorrectly configured on a host?
- The host cannot communicate with other hosts in the local network.
- The switch will not forward packets initiated by the host.
- The host will have to use ARP to determine the correct address of the default gateway.
- The host cannot communicate with hosts in other networks.*
- A ping from the host to 127.0.0.1 would not be successful.
- Which characteristic describes the default gateway of a host computer?
- the logical address of the router interface on the same network as the host computer*
- the physical address of the switch interface connected to the host computer
- the physical address of the router interface on the same network as the host computer
- the logical address assigned to the switch interface connected to the router
- Which statement is true about the TCP/IP and OSI models?
- The TCP/IP transport layer and OSI Layer 4 provide similar services and functions.*
- The TCP/IP network access layer has similar functions to the OSI network layer.
- The OSI Layer 7 and the TCP/IP application layer provide identical functions.
- The first three OSI layers describe general services that are also provided by the TCP/IP internet layer.
- What is an advantage of using standards to develop and implement protocols?
- A particular protocol can only be implemented by one manufacturer.
- Products from different manufacturers can interoperate successfully.*
- Different manufacturers are free to apply different requirements when implementing a protocol.
- Standards provide flexibility for manufacturers to create devices that comply with unique requirements.
