Which device should you use?DHCP Server.You are implementing a DHCP server for your segment. Your segment's IP address is 192.168.1.0. Your default gateway address is 192.168.1.254. Your DNS server address is 192.168.1.1. Your default gateway is configured as a NAT router to translate addresses between network segments. YOu configured the 03 Router option on your DHCP server so it can deliver the IP address of the default gateway to workstations. After configuring your workstations to get their IP address information dynamically, your users complain that they are unable to access web sites on the Internet. How can you resolve this problem?You must configure your DHCP server with an option that delivers the IP address of the DNS server (Option 06).Due to widespread network expansion, you have decided to upgrade the network by configuring a DHCP sever for the network uses Linux, Windows, and Mac OS X client systems. You configure the server to distribute IP addresses from 12.168.2.1 to address 192.168.2.100. You use the subnet mask of 255.255.255.0. after making al setting changes on the DHCP sever, you reboot each client system but they are not able to obtain an ip address from the dhcp server. Which of the following would explain the failure?the clients must be configured to obtain ip addressing from a dhcp serverYou have a TCP/IP network with 50 hosts. There has been inconsistant communication problems between hosts. You run a protocol analyzer and discover that two hosts have the same IP address assigned. Which protocol can you implement on your network to help prevent problems such as this?DHCPYou are configuring the DHCP Relay Agent role service on a Windows server. Which of the following is a required step for the configuration?Specify which server network interface the agent listens on for DHCP messages.You have a Windows Server 2012 system that you want to use as a DHCP Relay Agent. Which Windows Server 2012 service would you sue to do this?Routing and Remote AccessYou need to configure a Cisco RFC 1542 compliant router to forward any recieved DHCP frames to the appropriate subnet. The address of the remote DHCP server is 172.16.30.1. Which of the following commands would be used to configure the router?IP helper-address 172.16.30.1You need to enable hosts on your network to find the IP address of logical names such as srv1.myserver.com Which device would you use?DNS serverYou want to implement a protocol on your network that allows computers to find the IP address of a host from a logical name. Which protocol should you implement?DNSListed below are several DNS record types. Match the record the on the left with its function on the right.Points a hostname to an IPv4 A Provides alternate names to hosts that already have a host record. CNAME Points an IP address to a hostname PTR Points a hostname to an IPv6 address AAAA identifies servers that can be used to deliver mail. MXListed below are several DNS record types. Match the record type on the left with its function on the right.Identify a domain controller- SRV identify a mail server- MX Map a host name to an IPv4 address- A Map an IPv4 address to a host name- PTRwhich of the following services automatically creates and deletes host records wen an ip address lease is created or released?DYNAMIC DNSIf dynamic DNS is being used, which of the following events will cause a dynamic update of the host records?The DHCP server renews an ip address lease The ipconfig/release command is entered on a workstation.Which of the following are valid IPv6 IP addresses?6384:1319:7700:7631:446A:5511:8940:2552 141:0:0:0:15:0:0:1Which of the following is a valid IPv6 address?FEC0::AB:9007Match the IPv6 address configuration method on the right with it's definition on the left.Static Full Assignment: The entire 128-bit address and all other configuration information is statically assigned to the host. Static partial Assignment: The prefix is statically assignment and the interface ID is delivered from the MAC address. Stateless Auto-configuration: Clients automatically generate the interface ID and learn the subnet prefix and default gateway through the neighbor discovery protocol (NDP) Stateful DHCPv6: Provides each client an IP address, default gateway, and other IP configuration Stateless DHCPv6: Supplies the client with the DNS server IP address only. Does not provide the client with an IP address and does not track the status of each client.Which of the following tunneling methods is used to send IPv4 traffic through an IPv6 network?4-to-6 tunnelingYou manage a network with two locations: Portland and Seattle. Both locations are connected to the Internet. All computers in both locations are configured to use IPv6. You would like to implement an IPv6 solution to meet the following requirements: Hosts in each location should be able to use IPv6 to communicate with hosts in the other location through the IPv4 Internet. You want to use a site-to-site tunneling method instead of a host-to-host tunneling method. Which IPv6 solution should you use?6-to-4Which of the following are characteristics of Teredo tunneling?Works through NAT dual stack hosts tunnel endpoints configured on hostsYou have a special server at work with a custom application installed. Connections to the server that use custom application must use IPv6. The server is currently running IPv4. You are the only person who connects to the server, and you always use your laptop for the connection. Your laptop supports both IPv4 and IPv6. The rest of your company network runs only IPv4. You need a cost effective solution to allow your laptop to connect to the server. Your solution must also support communication through NAT servers. Which method should you use?MiredoYou manage a network that uses IPv6 addressing. When clients connect devices to the network, they generate an interface ID and use NDP to leanrthe subnet prefix and default gateway. Which IPv6 address assignment method is being used?Stateless auto configurationWhich type of address is used in a packet to address the packet to a single host?UnicastWhich type of address is the IP address 198.162.12.254/24?UnicastWhich of the following address types is shared by multiple hosts, and is used to form groups of computers that should receive the same data stream?MulticastWhich type of address is the IP address is the IP address 232.111.255.250?MulticastWhich protocol does an IP host use to inform a router that it wants to receive specific multicast frames?IGMPA video conference call consisting of multiple participants usesMulticastYou administer a network with windows 200 unix servers, ad windows 2000 professionl, windows 98, and macintosh clients.
