Enterprise Networking, Security, and Automation ( Version 7.00) – CCNA (200-301) Certification Practice Exam | with complete solutions

1. An instructor is reviewing student answers on a previous term exam to prepare for a lecture on IPv6. What would be a good point for the instructor to make when explaining an IPv6 GUA (global unicast address)? ▪ It is considered a best practice to use the IPV6 GUA address of the router as the default gateway address for Windows hosts. ▪ It can be configured statically or assigned dynamically on a router. ▪ It can only be configured statically on a host interface by using the ipv6 address command. ▪ It is routable on the IPv6 internet. 2. An administrator needs to implement a 2.4GHz WLAN that requires multiple APs. Which two are characteristics of the 2.4GHz channels? (Choose two.) ▪They can provide faster data transmission for wireless clients in heavily populated wireless networks than 5GHz channels. ▪Each channel is separated from the next channel by 20 MHz. ▪There are 11 channels for North America identified by the 802.11b standard. ▪ If three adjacent APs are required, the non-overlapping channels 1, 21, and 41 are recommended. ▪Each channel is allotted 22 MHz bandwidth. 3. A technician must accommodate at least 500 subnets from address 172.16.0.0/16. What is an appropriate subnet mask and corresponding number of available host IP addresses per subnet to meet the requirement? ▪255.255.255.128 and 126 hosts ▪255.255.255.0 and 128 hosts ▪255.255.255.192 and 126 hosts ▪255.255.255.224 and 128 hosts 4. Refer to the exhibit. A PC with the MAC address of 0800.069d.3841 attached to port Fa0/8 is sending data to a device that has the MAC address of 6400.6a5a.6821. What will the switch do first to handle the data transfer? ▪The switch will add the address 0800.069d.3841 to the MAC address table. ▪The switch will send the frame to ports Fa0/4 and Fa0/6. ▪The switch will flood the frame out all ports except port Fa0/8. ▪The switch will send the frame to port Fa0/6. ▪The switch will add the address 6400.6151.6821 to the MAC address table. Explanation: Every frame that enters a switch is checked for new information to learn. It does this by examining the source MAC address of the frame and port number where the frame entered the switch: If the source MAC address does not exist in the MAC address table, the MAC address and incoming port number are added to the table. 5. A network engineer is giving a tour of the company network operations center to a college class. The engineer is trying to describe how a WAN and connectivity to the internet relate to the network infrastructure. Which statement correctly describes network infrastructure and network communication? ▪Communication across the internet requires application of recognized technologies and standards. ▪LANs are used to connect WANs around the world. ▪A LAN connects small networks to large global networks. ▪The internet is a worldwide collection of interconnected networks owned by an organization. Explanation:The internet is not owned by any individual or group. Ensuring effective communication across this diverse infrastructure requires the application of consistent and commonly recognized technologies and standards as well as the cooperation of many network administration agencies.
