- IKT204-G H21, QUIC statements Which of the claims regarding QUIC is correct? Select correct alternatives: O QUIC is an old protocol designed in the 80's as an alternative to UDP and TCP. O QUIC belongs to the transport layer in the Internet five-layer protocol stack. O QUIC needs maximum 1 handshake phase to establish a secure connection. O QUIC is a relative new protocol originally designed by Google. O QUIC has algorithms for network congestion control and for handling packet loss. O QUIC belongs to the application layer in the Internet five-layer protocol stack. O QUIC uses a specified fixed encryption suite and needs no handshake phase to set up a connection. O QUIC uses UDP as transport protocol. O QUIC leaves network congestion control and reliable data transport to the application using QUIC. O QUIC uses TCP as transport protocol.How many layers make up the Internet Protocol stack? 5 7 8 10 Consider an HTTP client wants to retrieve a web document. Typically the IP address of the HTTP server is unknown. What transport and application-layer protocols (besides HTTP) are needed in this scenario? (Select all that Apply) DNS UDP TCP SMTP Switches forward packets to their intended target using Domain Names Port Numbers IP Addresses MAC AddressesFTP stands for File transfer protocol. FTP is a standard internet protocol provided by TCP/IP used for transmitting the files from one host to another. It is mainly used for transferring the web page files from their creator to the computer that acts as a server for other computers on the internet. It is also used for downloading the files to computer from other servers. What is the difference between active and passive FTP that makes stateful packet filtering a good idea?
- 1. Whihc protocol is used to securely interconnect network devices? O A: TCP OB: IPSEC C: L2TP D: PPTP O E: IP/VPN OF: IEEE802.1X 2. Which statment is true about the TCP 3 way-handshake (initiated by the host, and answered by a server)? O A: The server sends back the acknowledge as a SYN message with the same sequence number as it was received from the host. OB: The server sends back the acknowledge as a SYN message with the same sequence number as received. O C: The host always start the sequence numbering from 1024. OD: The server sends back the acknowledge as a SYN message with a random number as sequence ID. O E: Both the SYN-ACK and ACK messages uses a sequence number which is higher with one than the received one. (eg. if the received is 1024, then the ack is 1025) OF: Both SYN and SYN-ACK use random sequence number OG: None of aboveWireshark lab Homework & Lab Assignment Take screenshot for every answer you provide Repeat the steps on your local machine and answer the following: Name three protocols that you captured How long did it take from when the HTTP GET message was sent until the HTTP OK reply was received?
