Which two of the following are considered reserved IP addresses? (Choose two.) 0.x.y.z 127.x.y.z Which is the valid Class C IP address range? In which three ways do organizations benefit from using private IP addresses? (Choose three.) -They gain more network design flexibility with a large address range. -They prevent Internet address clashes when obtaining only a small range of Internet Corporation for Assigned Names and Numbers (ICANN) assigned addresses.-They conserve public IP addresses when uniqueness is not required. Which is a valid Class B network address? 151.129.89.76 Which are considered private Internet protocol (IP) addresses? (Choose three.) 10.0.0.0 172.31.255.255 192.168.0.0 The Internet Assigned Numbers Authority (IANA) recommends organizations use private IP addresses under which condition? The network uses gateways, routers, or firewalls to act on the network host's behalf. What does the class network number 127.x.y.z designate? A loopback address A Class D address is also known as which type of address? Multicast Which device provides the connection point between a workstation or personal computer (PC) and the network? Network interface card (NIC). Which network device can isolate broadcast traffic to the local network segment? Router. At what maximum distance would you have to add a repeater to a 10Base2 network segment to prevent signal degradation 185m Bridges and OSI/RM Layer 2 switches filter traffic in which way? By building physical address to port mappings and making forwarding decisions based on these mappings. A hub that repeats and regenerates signals is called which type of hub? Active Which network device allows us to connect dissimilar network topologies? Bridge. Which network device allows communication between separate IP networks? Router. Which three of the following networking devices break up collisions? (Choose three.) Bridge Switch Router Which network device requires a device driver in order to connect hosts to the network segment? Network interface card (NIC). Hubs connect network hosts in which configuration? Star What must the Network Layer do to a received frame first in order to determine the route over which it will forward the datagram to the next network? Decapsulate the packet. Which two of the following devices work only with the binary representations of network data? (Choose two.) Hub Repeader Which three devices forward broadcast traffic? (Choose three.) Switch. Bridge. Repeater. Which OSI/RM Data Link Layer 2 device creates multiple network segments, each offering the full network bandwidth? Switch Which three of the following are Dynamic Host Configuration Protocol (DHCP) address allocation mechanisms? (Choose three.) Automatic Dynamic Manual Which protocol allows clients to locate and download IP addressing and configuration information on an automatically renewable (lease) basis? Dynamic Host Configuration Protocol (DHCP). Which statement best describes Internet Message Access Protocol (IMAP)? IMAP allows users to scan email headers and choose email messages to download from the email server. If a Dynamic Host Configuration Protocol (DHCP) client fails to renew its lease at the 50-percent point, what happens next? It attempts to obtain a lease at 87.5-percent lease time. Internet email uses which two protocols? (Choose two.) Simple Mail Transfer Protocol (SMTP). Post Office Protocol version 3 (POP3). Which TCP/IP application allows us to transfer files either within a browser or at the command line? File transfer protocol (FTP). How does the Domain Name System (DNS) resolve fully qualified domain names (FQDN) to IP addresses? By looking up the names in an address mapping database. To resolve fully qualified domain names (FQDN) to binary IP addresses, resolvers contact which type of TCP/IP application server? Domain Name System (DNS). Which TCP/IP application allows a network user to remotely log on and manipulate a network device? Telnet. Of the five trivial file transfer protocol (TFTP) packet types, which three choices below are TFTP packet types? (Choose three.) Read request Write request Acknowledgment Which two choices are examples of trivial file transfer protocol (TFTP) use? (Choose two.) Download router upgrades.Software upgrades to IP telephones. Which Dynamic Host Configuration Protocol (DHCP) network address allocation mechanism assigns a host a temporary IP address Dynamic What happens when the browser application finishes downloading the files necessary to display a web page? The browser and server drop the connections, and the browser maintains the page and its elements in memory. Which best describes why an hypertext transfer protocol (HTTP) server can handle multiple simultaneous connections? HTTP is stateless, which means the server has no knowledge of previous Connections after they are dropped If you want to locate a previously saved Uniform Resource Locator (URL) so that you can quickly return to it as needed, where on the browser toolbar would you look? Favorites Which three of the following are common Telnet application uses? (Choose three.)
