(Choose three.)TCP uses port numbers to provide reliable transportation of IP packets.TCP and UDP port numbers are used by application layer protocols.TCP uses windowing and sequencing to provide reliable transfer of data.TCP is a connection-oriented protocol. UDP is a connectionless protocol.UDP uses windowing and acknowledgments for reliable transfer of data.CCNA5.NETCCNA5.NET - MIPDF.COMMIPDF.COM3 What is the purpose of ICMP messages?to inform routers about network topology changesto ensure the delivery of an IP packetto monitor the process of a domain name to IP address resolutionto provide feedback of IP packet transmissions4 A technician uses the ping 127.0.0.1 command. What is the technician testing?connectivity between a PC and the default gatewayconnectivity between two adjacent Cisco devicesphysical connectivity of a particular PC and the networkthe TCP/IP stack on a network hostconnectivity between two PCs on the same network5 What will a Layer 2 switch do when the destination MAC address of a received frame isnot in the MAC table?It notifies the sending host that the frame cannot be delivered.It initiates an ARP request.It forwards the frame out of all ports except for the port at which the frame was received.It broadcasts the frame out of all ports on the switch.6 What is a characteristic of the LLC sublayer?It places information in the frame that allows multiple Layer 3 protocols to use the same networkinterface and media.It provides delimitation of data according to the physical signaling requirements of the medium.It defines software processes that provide services to the physical layer.It provides the logical addressing required that identifies the device.CCNA5.NETCCNA5.NET - MIPDF.COMMIPDF.COM7On which switch interface would an administrator configure an IP address so that theswitch can be managed remotely?VLAN 1console 0vty 0FastEthernet0/18A network engineer is measuring the transfer of bits across the company backbone for amission critical database application. The engineer notices that the network throughputappears lower than the bandwidth expected. Which three factors could influence thedifferences in throughput? (Choose three.)the reliability of the gigabit Ethernet infrastructure of the backbonethe amount of traffic that is currently crossing the networkthe type of traffic that is crossing the networkthe sophistication of the encapsulation method applied to the datathe bandwidth of the WAN connection to the Internetthe latency that is created by the number of network devices that the data is crossing9When applied to a router, which command would help mitigate brute-force passwordattacks against the router?service password-encryptionlogin block-for 60 attempts 5 within 60banner motd $Max failed logins = 5$exec-timeout 3010Which two statements correctly describe a router memory type and its contents?
