QUESTION 1 What are two common TCP applications? (Choose two.) A. TFTP B. SMTP C. SNMP D. FTP E. DNS Correct Answer: BD Explanation/Reference: SMTP uses TCP port 25, 010-151 dumps 070-243 exam 070-341 dumps 070-347 dumps 70-410 dumps 070-410 dumps 070-413 dumpswhile FTP uses TCP ports 20 and 21.

What two things can the technician determine by successfully pinging from this computer to the IP address 172.16.236.1? (Choose two) A. The network card on the computer is functioning correctly. B. The default static route on the gateway070-461 dumps 070-463 dumps 070-464 dumps 070-483 dumps 070-487 dumps 070-489 dumps router is correctly configured. C. The correct default gateway IP address is configured on the computer. D. The device with the IP address 172.16.236.1 is reachable over the network. E. The default gateway at 172.16.236.1 is able to forward packets to the internet. Correct Answer: AD Explanation/Reference: The source and destination addresses are on the same network therefore, a default gateway is not necessary for communication between these two addresses. QUESTION 3 A company has placed a networked PC in a lobby so guests can have access to the corporate directory. A security concern is that someone will disconnect the directory PC and re-connect their laptop computer and have access to the corporate network. For the port servicing the lobby, which three configuration steps should be performed on the switch to prevent this? (Choose three.) A. Enable port security. B. Create 101 exam 101-400 exam 117-201 dumps 117-202 dumps 1K0-001 dumpsthe port as a trunk port. C. Create the port as an access port. D. Create the port as a protected port. E. Set the port security aging time to 0. F. Statically assign the MAC address to the address table. G. Configure the switch to discover new MAC addresses after a set time of inactivity. Correct Answer: ACF Explanation/Reference: If port security is enabled and the port is only designated as access port, and finally static MAC address is assigned, it ensures that even if a physical connection is done by taking out the dire QUESTION 4 After the network has converged, what type of messaging, if any, occurs between R3 and R4? A. No messages are exchanged B. Hellos are sent every 10 seconds. C. The full database from each router is sent every 30 seconds. 210-250-dumps 210-255-dumps 200-150-dumps 200-155-dumps 300-160-dumps 300-165-dumps D. The routing table from each router is sent every 60 seconds. Correct Answer: B Explanation/Reference: HELLO messages are used to maintain adjacent neighbors so even when the network is converged, hellos are still exchanged. On broadcast and point-to-point links, the default is 10 seconds, on NBMA th QUESTION 5 Which dynamic routing protocol uses only the hop count to determine the best path to a destination? A. IGRP B. RIP C. EIGRP D. OSPF Correct Answer: C Explanation/Reference: QUESTION 6 Refer to the topology and partial configurations shown in the exhibit. The network administrator has finished configuring the NewYork and Sydney routers and issues the command ping Sydney from the NewYork router. The ping fails. What command or set of commands should the network administrator issue to correct this problem? A. Sydney(config)# interface s0/0 Sydney(config-if)#cdp enable B. Sydney(config)# interface s0/0 Sydney(config-if)# no shut C. Sydney(config)# line vty 0 4 Sydney(config)# login Sydney(config)# password Sydney D. Sydney(config)# ip host Sydney 10.1.1.9 E. Sydney(config)# interface s0/0 Sydney(config-if)#ip address 10.1.1.5 255.255.255.252 NewYork(config)# ip host Sydney 10.1.1.5 Correct Answer: E Explanation/Reference: Explanation: The IP addresses on the two 300-170 dumps 300-175 dumps 300-180 dumps 300-210 dumps 600-509 dumps 600-510 dumps Serial interfaces of two routers are not in the same subnet so they could not recognize each other and the ping failed. Therefore we must correct the IP addr QUESTION 7 An administrator is in the process of changing the configuration of a router. What command will allow the administrator to check the changes that have been made prior to saving the new configuration? A. Router# show startup-config B. Router# show current-config C. Router# show running-config D. Router# show memory E. Router# show flash F. Router# show processes Correct Answer: C Explanation/Reference: This command followed by the appropriate parameter will show the running config hence the admin will be able to see what changes have been made, and then they can be saved. QUESTION 8 Which protocol uses a connection-oriented service to deliver files between end systems? A. TFTP B. DNS C. FTP D. SNMP E. RIP Correct Answer: C Explanation/Reference: TCP is an example of a connection-oriented protocol. It requires a logical connection to be established between the two processes before data is exchanged. The connection must be maintained during t QUESTION 9 Which statement about a router on a stick is true? A. Its date plane router traffic for a single VI AN over two or more switches. 200-125 dumps 100-105 dumps 210-260 dumps 300-115 dumps 200-105 dumps 300-101 dumps 200-310 dumps B. It uses multiple subinterfaces of a single interface to encapsulate traffic for different VLANs on the same subnet. C. It requires the native VLAN to be disabled. D. It uses multiple subinterfaces of a single interface to encapsulate traffic for different VLANs. Correct Answer: D Explanation/Reference: https://www.freeccnaworkbook.com/workbooks/ccna/configuring-inter-vlan-routing-router- on-a-stick QUESTION 10 Refer to the exhibit. Assume that all router interfaces are operational and correctly configured. In addition, assume that OSPF has been correctly configured on router R2. How will the default route configured on R1 affect the operation of R2? A. Any packet destined for a network that is not directly connected to router R2 will be dropped immediately. B. Any packet destined for a network that is not referenced in the routing table of router R2 will be directed to R1. R1 will 210-060 dumps 200-355 dumps 640-911 dumps 300-075 dumps 300-320 dumps 300-208 dumps then send that packet back to R2 and a routing loop will occur. C. Any packet destined for a network that is not directly connected to router R1 will be dropped. D. The networks directly connected to router R2 will not be able to communicate with the 172.16.100.0, 172.16.100.128, and 172.16.100.64 subnetworks. E. Any packet destined for a network that is not directly connected to router R2 will be dropped immediately because of the lack of a gateway on R1. Correct Answer: B Explanation/Reference: First, notice that the more-specific routes will always be favored over less-specific routes regardless of the administrative distance set for a protocol. 300-135 dumps 210-065 dumps 300-206 dumps 300-070 dumps 300-209 dumps 300-360 dumps 642-998 dumpsIn this case, because we use OSPF for three QUESTION 11 Which IP address is a private address? A. 220.127.116.11 B. 18.104.22.168 C. 172.20.14.36 D. 22.214.171.124 E. 126.96.36.199 Correct Answer: C QUESTION 12 Refer to the exhibit.
