Whatcommand should be issued?copy startup-config flashcopy running-config flashreloadcopy startup-config running-configcopy running-config startup-config*2Which IPv4 header field is responsible for defining the priority of the packet?traffic classflow labelflagsdifferentiated services*3When connectionless protocols are implemented at the lower layers of the OSI model, what areusually used to acknowledge the data receipt and request the retransmission of missing data?Transport layer UDP protocolsupper-layer connection-oriented protocols*connectionless acknowledgementsNetwork layer IP protocols4Why is NAT not needed in IPv6?Any host or user can get a public IPv6 network address because the number of available IPv6addresses is extremely large.*The end-to-end connectivity problems that are caused by NAT are solved because the number ofroutes increases with the number of nodes that are connected to the Internet.Because IPv6 has integrated security, there is no need to hide the IPv6 addresses of internalnetworks.The problems that are induced by NAT applications are solved because the IPv6 header improvespacket handling by intermediate routers.5Refer to the exhibit. Fill in the blank.A packet leaving PC-1 has to traverse “three” hops to reach PC-4.By CCNA5.NETDownloaded from MIPDF.COM6Which two interfaces will allow access via the VTY lines to configure the router? (Choose two.)console interfacesUSB interfacesWAN interfaces*LAN interfaces*aux interfaces7A technician is manually configuring a computer with the necessary IP parameters tocommunicate over the corporate network. The computer already has an IP address, a subnetmask, and a DNS server. What else has to be configured for Internet access?the default gateway address*the MAC addressthe domain name of the organizationthe WINS server address8Which three commands are used to set up a password for a person who attaches a cable to anew router so that an initial configuration can be performed? (Choose three.)password cisco *line vty 0 4line console 0 *interface fastethernet 0/0enable secret ciscologin *910By CCNA5.NETDownloaded from MIPDF.COM11Which statement about router interfaces is true?Commands that apply an IP address and subnet mask to an interface are entered in globalconfiguration mode.Once the no shutdown command is given, a router interface is active and operational.Router LAN interfaces are not activated by default, but router WAN interfaces are.A configured and activated router interface must be connected to another device in order tooperate.*12A technician is configuring a router that is actively running on the network. Suddenly, power tothe router is lost. If the technician has not saved the configuration, which two types ofinformation will be lost? (Choose two.)routing table*ARP cache*Cisco IOS image fileBy CCNA5.NETDownloaded from MIPDF.COMstartup configurationbootstrap file1314How do hosts ensure that their packets are directed to the correct network destination?They always direct their packets to the default gateway, which will be responsible for the packetdelivery.They send a query packet to the default gateway asking for the best route.They search in their own local routing table for a route to the network destination address and passthis information to the default gateway.They have to keep their own local routing table that contains a route to the loopback interface,a local network route, and a remote default route.*15What is a service provided by the Flow Label field of the IPv6 header?It identifies the total length of the IPv6 packet.It limits the lifetime of a packet.It informs network devices to maintain the same path for real-time application packets.*It classifies packets for traffic congestion control.16During the process of forwarding traffic, what will the router do immediately after matching thedestination IP address to a network on a directly connected routing table entry?look up the next-hop address for the packetBy CCNA5.NETDownloaded from MIPDF.COMdiscard the traffic after consulting the route tableswitch the packet to the directly connected interface*analyze the destination IP address17Fill in the blank.In a router, “ROM ” is the nonvolatile memory where the diagnostic software, the bootup instructions,and a limited IOS are stored.18Which two commands can be used on a Windows host to display the routing table? (Choosetwo.)netstat -sroute print*netstat -r*tracertshow ip route19A computer has to send a packet to a destination host in the same LAN. How will the packet besent?The packet will be sent directly to the destination host.*The packet will be sent only to the default gateway.The packet will be sent to the default gateway first, and then, depending on the response from thegateway, it may be sent to the destination host.The packet will first be sent to the default gateway, and then from the default gateway it will be sentdirectly to the destination host.20Which command displays a summary chart of all router interfaces, their IP addresses, and theircurrent operational status?show interfacesshow versionshow ip routeshow ip interface brief *21Which two files, if found, are copied into RAM as a router with the default configuration registersetting boots up? (Choose two.)POST diagnosticsrunning configurationstartup configuration*IOS image file*22Open the PT Activity. Perform the tasks in the activity instructions and then answer thequestion or complete the task.
