Which of the following tools could you use? - ANSWER Address resolution protocol (ARP) What is the primary difference between transmission control protocol (TCP) and user datagram protocol (UDP)? - ANSWER -TCP messages are tracked to ensure they are recieved; UDP messages are sent without tracking. The five stages of (1) obtaining logical addresses, (2) obtaining physical addresses, (3) establishing a connection between applications, (4) the transfer of information, (5) the termination of the connection are necessary to accomplish what? - ANSWER -The transfer of information accross a transmission control protocol/internet protocol (TCP/IP) network Where does the Domain Name System (DNS) namespace begin? - ANSWER Root Domains The maximum Domain Name System (DNS) domain name length is how many bytes? - ANSWER -255 Zones maintain domain name information in which record type? - ANSWER Resource records When Dynamic Host Configuration Protocol (DHCP) carries vendor specific options, what tells the client the vendor specific format? - ANSWER -Codes 128 256 At which point in the Dynamic Host Configuration Protocol (DHCP) lease dos the client first attempt to renew its lease? - ANSWER -50% Which is the correct destination of a user datagram protocol (UDP) port number for a DHCPDISCOVER message? - ANSWER -67 When network address translation (NAT) uses IP (internet protocol) address translation, it assigns external address to internal devices in which way? - ANSWER -it assigns the internal address to one of a pool of external addresses Which statement best describes network address translation (NAT) masquerading? - ANSWER -it hides all internal addresses behind one external address What does the Domain Name Systems (DNS) allow users to do? - ANSWER Distinguish between two similar names For Dynamic Host Configuration Protocol (DHCP) , what are the hosts requesting and supplying the configuration parameters called? - ANSWER -The client request parameters and the server provides the parameters A router makes its packet forwarding decision based on what information? - ANSWER -The routers routing table On which network type is a static route best used? - ANSWER -stub routing Which network address represents a default route? - ANSWER -0.0.0.0/0. Which router protocol type shares routing information within the autonomous system (AS)? - ANSWER -Interior Gateway Protocol (IGP). Distance Vector Algorithms (DVA) operate in wihch manner? - ANSWER -They advertise their routing tables directly to directly connected neighbor routers. What can cause routing loops in the flat router architecture? - ANSWER -The router receives data packets before it receives routing information, causing the router to generate additional address request messages for routing information What are routers that belong to the same autonomous system (AS) called? - ANSWER -Interior neighbors What is a benefit of using static routes? - ANSWER -No bandwidth usage passing updates between routers. Why are routers known as neighbors or peers? - ANSWER -because they exchange routing information When using multipath routing and multiple routes are available for a single destination address, how does the router make the route section? - ANSWER -it selects the route with the highest precedence. Which of the following is a characteristic of static routing? - ANSWER -Static systems do not operate well in an environment of rapid growth or change. When a client connects to a web browser, the first action is typically media access control (MAC) address resolution. Under what circumstance may address resolution be bypassed? - ANSWER -When the client has recently made a request to the same server Which hypertext transfer protocol (HTTP) message request from the client allows it to obtain additional information regarding options and requirements without initiating any actions on the part of the server? - ANSWER -options What are some of the issues that can arise when making a file available for transfer to other users? - ANSWER -Data type, file structure, and transmission mode. What are the common file extensions used to transfer image data in file transfer protocol (FTP)? - ANSWER -Bitmap (.BMP), graphics interchange format (GIF), and joint photography experts group (.JPG or .JPEG) What is the name of the protocol by which management information for a network element can be inspected or altered by a management station? - ANSWER -Simple network management protocol (SNMP)
