Networking Mod 7 & 8
| Question | Answer |
|---|---|
| What is the purpose of using a source port number in a TCP communication? | to keep track of multiple conversations between devices |
| Which number or set of numbers represents a socket? | 192.168.1.1:80 |
| Which transport layer feature is used to guarantee session establishment? | TCP 3-way handshake |
| What is the complete range of TCP and UDP well-known ports? | 0 to 1023 |
| Network congestion has resulted in the source learning of the loss of TCP segments that were sent to the destination. What is one way that the TCP protocol addresses this? | The source decreases the amount of data that it transmits before it receives an acknowledgement from the destination. |
| How does a networked server manage requests from multiple clients for different services? | Each request has a combination of source and destination port numbers, coming from a unique IP address. |
| Each request has a combination of source and destination port numbers, coming from a unique IP address. | SYN ACK |
| What is a responsibility of transport layer protocols? | tracking individual conversations |
| What type of applications are best suited for using UDP? | applications that are sensitive to delay |
| What happens if part of an FTP message is not delivered to the destination? | The part of the FTP message that was lost is re-sent. |
| Which two are protocols that belong in the OSI application layer? | SMTP DNS |

| Which peer-to-peer application allows users to share pieces of many files with each other at the same time? | BitTorrent |
| What is a well-known format for videos? | MPG |
| Encrypting data for transmission and decrypting data upon receipt, is a function of which layer? | Presentation Layer |
| True or false? The peer-to-peer networking model requires the implementation of a dedicated server for data access. | False |
| MKV, GIF, and JPG standards are associated with which OSI layer? | presentation |
| This is a function of the OSI session layer. | exchange of information to initiate dialog between peers |
| What part of the URL, represents the top-level DNS domain? | .com |
| What are two characteristics of the application layer of the TCP/IP model? (Choose two.) | - the creation and maintenance of dialogue between source and destination applications - closest to the end user |
| Which two tasks can be performed by a local DNS server? (Choose two.) | - mapping name-to-IP addresses for internal *hosts - forwarding name resolution requests between servers |

| When retrieving email messages, which protocol allows for easy, centralized storage and backup of emails that would be desirable for a small- to medium-sized business? | IMAP |
| Which protocol uses encryption? | HTTPS |
| Why is DHCP preferred for use on large networks? | It is a more efficient way to manage IP addresses than static address assignment. |
| Which protocol can be used to transfer messages from an email server to an email client? | POP3 |
| Which action is performed by a client when establishing communication with a server via the use of UDP at the transport layer? | The client randomly selects a source port number. |
| What is a socket? | the combination of a source IP address and port number or a destination IP address and port number |
| Which two services or protocols use the preferred UDP protocol for fast transmission and low overhead? (Choose two) | DNS VoIP |
| What is the TCP mechanism used in congestion avoidance? | sliding window |
| These three OSI layers define the same functions as the TCP/IP model application layer. | presentation application session |
| What is a well-known format for videos? | MOV |
| This layer of the OSI model is concerned with the protocols that exchange data between programs running on hosts. | application |
| Compressing data in a way that can be decompressed by the destination device, is a function of which layer? | Presentation Layer |
| Which application layer protocol is used to provide file-sharing and print services to Microsoft applications? | SMB |
| A wireless host needs to request an IP address. What protocol would be used to process the request? | DHCP |
| Which two operations are provided by TCP but not by UDP? (Choose two.) | retransmitting any unacknowledged data acknowledging received data |
| What is a well-known graphic-image format? | GIF |
| Which of the following is a feature of the Gnutella protocol? | Users can share whole files with other users. *(marked as incorrect) Users can share pieces of files with other users. |
| Which TCP/IP model layer is closest to the end user? | application |
