Document Content and Description Below

You are configuring a firewall to use NAT. In the configuration, you map a private IP address directly to a persistent public IP address. What form of NAT is being used? Registered NAT Static Nat... Dynamic NAT Advanced NAT Correct Answer. Ques 1 / 1 pts tion 2 Which of these best describes dynamic routing? All network addresses must be hand-typed into the routing table. Routing tables are updated automatically when changes occur in the network. Only a portion of the network address must be hand-typed into the routing table. The network administrator must make changes to the routing table when changes occur in the network. Correct answer. Ques 1 / 1 pts tion 3 Which of the following describes the purpose of DHCP? Applying prioritization to certain types of network traffic. Resolving FQDNs to IP addresses. Filtering web content based on keywords. Dynamic assignment of IP addresses. Correct answer. Q 1 / 1 pts uestion 4 Which part of an IP packet does the router use to make routing decisions? source IP address source MAC address destination IP address destination MAC address Correct answer. Ques 0 / 1 pts tion 5 Incorrect What is the purpose of a default gateway? provides a permanent address to a computer identifies the network to which a computer is connected identifies the logical address of a networked computer and uniquely identifies it to the rest of the network identifies the device that allows local network computers to communicate with devices on other networks Incorrect answer. Ques 1 / 1 pts tion 6 Refer to the exhibit. The switches are in their default configuration. Host A needs to communicate with host D, but host A does not have the MAC address for its default gateway. Which network hosts will receive the ARP request sent by host A? only host D only router R1 only hosts A, B, and C only hosts A, B, C, and D only hosts B and C only hosts B, C, and router R1 Correct answer. Ques 1 / 1 pts tion 7 Which application is most likely used to translate www.cisco.com (http://www.cisco.com) to 198.133.219.25? DHCP DNS FTP HTTP Correct answer. Ques 1 / 1 pts tion 8 Which of the following ports does HTTP use, by default? 20 80 110 53 Correct answer. Ques 1 / 1 pts tion 9 Which of the following are advantages of using NAT? 1. Translation introduces switching path delays. 2. Conserves legally registered addresses. 3. Causes loss of end-to-end IP traceability. 4. Increases flexibility when connecting to the Internet. 5. Certain applications will not function with NAT enabled. 6. Reduces address overlap occurrence. 1, 3 and 4 3, 5 and 6 5 and 6 2, 4 and 6 Correct answer. Ques 1 / 1 pts tion 10 A computer configured to use DHCP cannot locate a DHCP server. Automatic Private IP Address (APIPA) will assign which of the following addresses? 172.16.1.25 192.168.1.25 169.254.1.25 10.16.1.25 Correct answer. Ques 1 / 1 pts tion 11 In the simplest wireless LAN configuration, all devices equipped with a client adapter can communicate directly with one another. Which term describes this configuration? Infrastructure Ad Hoc Roaming Microcellular Correct answer. Ques 1 / 1 pts tion 12 Routing tables of a router keeps track of MAC address assignments Port Assignment to network devices Routes to use for forwarding data to its destination Distribute IP addresses to network devices Correct answer. Ques 1 / 1 pts tion 13 In distance vector routing, each node periodically shares its routing table with _________ and whenever there is a change. every other node its immediate neighbors one neighbor none of the above Correct answer. Ques 1 / 1 pts tion 14 A router: forwards a packet to all outgoing links, except the link upon which the packet originated. determines on which outgoing link a packet is to be forwarded. forwards a packet to all outgoing links. forwards a packet to the next free outgoing link. Correct answer. Q 1 / 1 pts uestion 15 Which of the following is the difference between static and dynamic routing? Static routes are added automatically. Static routing is best used in large scalable networks. Dynamic routes are added automatically. Dynamic routing is used by a WINS server Correct answer. Q 0 / 1 pts uestion 16 Incorrect Refer to the graphic. What feature can be installed on the Linksys integrated router to convert private IP addresses to Internet-routable addresses? [Show More]
