CCNA Drag and Drop Questions

Question 1: A dental firm is redesigning the network that connects its three locations. The administrator gave the networking team 192.168.164.0 to use for addressing the entire netwok. After subnetting the address, the team is ready to assign the addresses. The administrator plans to configure ip subnet-zero and use RIP v2 as the routing protocol. As a member of the networking team, you must address the network and at the same time conserver unused addresses for future growth. With those goals in mind, drag the host addresses on the left to the correct router interface. Once of the routers is partially configured. Move your mouse over a router to view its configuration. Not all of the host addresses on the left are necessary. Answer: Explanation:  In short, we should start calculating from the biggest network (with 16 hosts) to the smallest one using the formula 2 n - 2 (n is the number of bits we need to borrow).Therefore:   16 hosts < 2 5 - 2 (we need to borrow 5 bits -> /27

(Updated from real CCNA exam on 12-20-2008) This topology contains 3 routers and 1 switch. Complete the topology. Drag the appropriate device icons to the labeled Device Drag the appropriate connections to the locations labeled Connections. Drag the appropriate IP addresses to the locations labeled IP address (Hint: use the given host addresses and Main router information) To remove a device or connection, drag it away from the topology. Use information gathered from the Main router to complete the configuration of any additional routers . No passwords are required to access the Main router. The config terminal command has been disabled for the HQ router. The router does not require any configuration. Configure each additional router with the following: Configure the interfaces with the correct IP address and enable the interfaces. Set the password to allow console access to consolepw Set the password to allow telnet access to telnetpw Set the password to allow privilege mode access

CCNA Troubleshooting Questions 2

Question 1: A network administrator is troubleshooting the OSPF configuration of routers R1 and R2. The routers cannot establish an adjacency relationship on their common Ethernet link. The graphic shows the output of the show ip ospf interface e0 command for routers R1 and R2. Based on the information in the graphic, what is the cause of this problem? A. The OSPF area is not configured properly. B. The priority on R1 should be set higher. C. The cost on R1 should be set higher. D. The hello and dead timers are not configured properly. E. A backup designated router needs to be added to the network. F. The OSPF process ID numbers must match. Answer: D Question 2: This graphic shows the results of an attempt to open a Telnet connection to router ACCESS1 from router Remote27. Which of the following command sequences will correct this problem? A. ACCESS1(config)# line console 0 ACCESS1(config-line)# password cisco B. Remote27(config)# line console 0 Remote27(config-line)# login Remote27(co

CCNA Troubleshooting Questions 1

Question 1: Refer to the exhibit. The network administrator is in a campus building distant from Building B. WANRouter is hosting a newly installed WAN link on interface S0/0. The new link is not functioning and the administrator needs to determine if the correct cable has been attached to the S0/0 interface. How can the administrator accurately verify the correct cable type on S0/0 in the most efficient manner? A. Telnet to WANRouter and execute the command show interfaces S0/0 B. Telnet to WANRouter and execute the command show processes S0/0 C. Telnet to WANRouter and execute the command show running-configuration D. Telnet to WANRouter and execute the command show controller S0/0 E. Physically examine the cable between WANRouter S0/0 and the DCE. F. Establish a console session on WANRouter and execute the command show interfaces S0/0 Answer: D Explanation: The show controller command displays the information about the physical interface itself and the type of serial cable plugged
