64 Ralph, the administrator of a 500-node private internetwork, is devising a plan to connect the network to the Internet. The primary objective of the project is to provide all of the network users with access to web and email services while keeping the client computers safe from unauthorized users on the Internet. The secondary objectives of the project are to avoid having to manually configure IP addresses on each one of the client computers individually and to provide a means of monitoring and regulating the users’ access to the Internet. Ralph submits a proposal calling for the use of private IP addresses on the client computers and a series of proxy servers with public, registered IP addresses, connected to the Internet using multiple T-1 lines. Which of the following statements about Ralph's proposed Internet access solution is true?The proposal fails to satisfy both the primary and secondary objectives.The proposal satisfies the primary objective but neither of the secondary objectives.The proposal satisfies the primary objective and one of the secondary objectives.The proposal satisfies the primary objective and both of the secondary objectives.

84 Which of the following statements about Routing Information Protocol version 1 (RIPv1) is true? (Choose all that apply.)RIPv1 broadcasts the entire contents of the routing table every 30 seconds.RIPv1 advertises the subnet mask along with the destination network.RIPv1 broadcasts only the elements in the routing table that have changed every 60 seconds.RIPv1 does not include the subnet mask in its network advertisements.
