Open the PT activity. Perform the tasks in the activity instructions and then answer the question. Which interfaces in each router are active and operational? OR1: G0/1 and S0/0/1 R2: G0/0 and S0/0/1 OR1: G0/0 and S0/0/0 R2: G0/1 and S0/0/0 OR1: G0/0 and S0/0/0 R2: G0/0 and S0/0/0 R1: G0/0 and S0/0/1 R2: G0/1 and S0/0/1 ITN (Version 7.00) - Communicating Between Networks Exam 2 What are two potential network problems that can result from ARP operation? (Choose two.) O Multiple ARP replies result in the switch MAC address table containing entries that match the MAC addresses of hosts that are connected to the relevant switch port. Network attackers could manipulate MAC address and IP address mappings in ARP messages with the intent of intercepting network traffic. O Manually configuring static ARP associations could facilitate ARP poisoning or MAC address spoofing. Large numbers of ARP request broadcasts could cause the host MAC address table to overflow and prevent the host from communicating on the network. On large networks with low bandwidth, multiple ARP broadcasts could cause data communication delays. ITN (Version 7.00) - Communicating Between Networks Exam 3 What is the effect of using the Router# copy running-config startup-config command on a router? O The contents of flash will change. O The contents of RAM will change. O The contents of ROM will change. The contents of NVRAM will change. ITN (Version 7.00) - Communicating Between Networks Exam 5 Which term describes a field in the IPv4 packet header that contains a 32-bit binary value associated with an interface on the sending device? O header checksum OTTL Osource IPv4 address O protocol Take Assessment ITN (Version 7.00) - Communicating Between Networks Exam 6 Which parameter does the router use to choose the path to the destination when there are multiple routes available? O the higher gateway IP address to get to the destination network O the lower gateway IP address to get to the destination network O the higher metric value that is associated with the destination network O the lower metric value that is associated with the destination network ITN (Version 7.00) - Communicating Between Networks Exam 7 Which statement describes a feature of the IP protocol? OIP encapsulation is modified based on network media. O MAC addresses are used during the IP packet encapsulation. O IP relies on Layer 2 protocols for transmission error control. IP relies on upper layer services to handle situations of missing or out-of-order packets. ITN (Version 7.00) - Communicating Between Networks Exam 8 A computer can access devices on the same network but cannot access devices on other networks. What is the probable cause of this problem? O The computer has an incorrect subnet mask. O The cable is not connected properly to the NIC. O The computer has an invalid IP address. O The computer has an invalid default gateway address. ITN (Version 7.00) - Communicating Between Networks Exam 9 What information does the loopback test provide? O The device has end-to-end connectivity. O The TCP/IP stack on the device is working correctly. O The Ethernet cable is working correctly. O The device has the correct IP address on the network. ODHCP is working correctly. assessment.netacad.net/virt Take Assessment ITN (Version 7.00) - Communicating Between Networks Exam 10 What IPv4 header field identifies the upper layer protocol carried in the packet? O Differentiated Services O Protocol delivery/pub-doc/2.0/assessment/1.1.0/exam.MLM O Version Identification ITN (Version 7.00) - Communicating Between Networks Exam 11 Within a production network, what is the purpose of configuring a switch with a default gateway address? O Hosts that are connected to the switch can use the switch default gateway address to forward packets to a remote destination. The default gateway address is used to forward packets originating from the switch to remote networks. OA switch must have a default gateway to be accessible by Telnet and SSH. O It provides a next-hop address for all traffic that flows through the switch. ITN (Version 7.00) - Communicating Between Networks Exam 12 Which field in the IPv4 header is used to prevent a packet from traversing a network endlessly? O Time-to-Live O Differentiated Services O Sequence Number O Acknowledgment Number S1 PC1 Othe MAC address of S2 EN English (United Sta Refer to the exhibit. PC1 attempts to connect to File_server1 and sends an ARP request to obtain a destination MAC address. Which MAC address will PC1 receive in the ARP reply? O the MAC address of the GO/O interface on R2 O the MAC address of S1 O the MAC address of File_server1 $2 O the MAC address of the G0/0 interface on R1 File_server1 ITN (Version 7.00) - Communicating Between Networks Exam 20 Under which two circumstances will a switch flood a frame out of every port except the port that the frame was received on? (Choose two.) The destination address in the frame is a known unicast address. The frame has the broadcast address as the destination address. The source address in the frame is a multicast address. The source address in the frame header is the broadcast address. The destination address is unknown to the switch. Take Assessment ITN (Version 7.00) - Communicating Between Networks Exam 21 What is the aim of an ARP spoofing attack? Oto overwhelm network hosts with ARP requests O to fill switch MAC address tables with bogus addresses Oto flood the network with ARP reply broadcasts to associate IP addresses to the wrong MAC address Floor(config-if)# description Connects to the ISP Floor(config-if)# ip address 10.62.63.254 255.255.255.0 Floor(config-if)# no shutdown Floor(config-if)# interface s0/0/1 Floor(config-if)# description Connects to the Head Office WAN Floor(config-if)# ip address 209.165.200.87 255.255.255.0 Floor(config-if)# no shutdown Floor(config-if)# end EN English (United Sta Refer to the exhibit. A network administrator is connecting a new host to the Manager LAN. The host needs to communicate with remote networks. What IP address would be configured as the default gateway on the new host? O 10.118.62.1 O 10.62.63.254 O 10.118.62.196 O 10.118.63.65 O209.165.200.87 ITN (Version 7.00) - Communicating Between Networks Exam 23 What property of ARP causes the request to be flooded out all ports of a switch except for the port receiving the ARP request? OARP replies are broadcast on the network when a host receives an ARP request. O Entries in an ARP table are time-stamped and are purged after the timeout expires. The type field 0x806 appears in the header of the Ethernet frame. OThe destination MAC address FF-FF-FF-FF-FF-FF appears in the header of the Ethernet frame.
