QUESTION 10 What is true regarding IPv4? O a. IPv4 is based upon the packet switching concept that guarantees packet delivery and quality-of-service (QoS) b. IPv4 requires source and destination addressing because it is a connection-oriented protocol that guarantees proper sequential packet delivery O c. IPv4 is a connectionless protocol that is “best effort” only O d. IPv4 is similar to TCP in that it establishes a connection-oriented service between communicating nodes
QUESTION 13 Select the correct statement(s) regarding TCP. a. TCP is a connectionless protocol O b. TCP uses port assignments to deliver packets to the correct applications O c. TCP does not guarantee the proper sequencing of delivered packets O d. all of the above are correct statements
QUESTION 19 Select the correct statement(s) regarding DHCP. a. DHCP is used to extend limited IPv4 addressing, therefore there is no plan to use DHCP with IPv6 O b. DHCP enables IP address assignments through manual, automatic, and dynamic processes O c. the DHCP protocol strictly operates in a distributed peer-to-peer manner O d. all statements are correct
QUESTION 22 Select the correct statement(s) regarding the TCP “windowing” concept. O a. once TCP establishes a connection between source and destination, the window size is established and does not change regardless of network conditions b. the TCP windowing concept is only used with unguided medium to ensure communications when RFI conditions are poor O c. the windowing mechanism is used to control network congestion by changing window sizes as network conditions change O d. both a and b are correct
QUESTION 24 Select the correct statement(s) regarding IPv4 Addresses. O a. IETF CIDR format enables ISPs to subnet their packet networks O b. the subnet mask 222.214.171.124 identifies a class A address OC. IPv4 128-bit address is divided into four octets that can be represented by hexidecimal numbers O d. all statements are correct
Answer10) What is true regarding IPv4 C. IPv4 Asia connectionless protocol that is ” best effort” only. 13). Select correct statement regarding TCP b). TCP uses port assignments to deliver packets to the correct applications. 19). Select the correct statements regarding DHCP b). DHCP enables IP address assignments through mutual ,automatic, and dynamic process. 22). Select the correct statement regarding TCP windowing concept C). the windowing mechanism is used to control network congestion by changing Windows size as network conditions change.
