CCNA 1 Final Exam Questions And Answers (v5.1+v6.0) Latest 2023. Version 6.0: 1. What is a characteristic of a fault tolerant network? a network that protects confidential information from unauthorized access a network that can expand quickly to support new users and applications without impacting the performance of the service delivered to existing users a network that supports a mechanism for managing congestion and ensuring reliable delivery of content to all users a network that recovers quickly when a failure occurs and depends on redundancy to limit the impact of a failure Explain: Fault tolerant networks limit the impact of a failure because the networks are built in a way that allows for quick recovery when such a failure occurs. These networks depend on multiple or redundant paths between the source and destination of a message. A scalable network can expand quickly to support new users and applications without impacting the performance of the service being delivered to existing users. Quality of service (QoS) is a mechanism for managing congestion and ensuring reliable delivery of content to all users. 2. Three bank employees are using the corporate network. The first employee uses a web browser to view a company web page in order to read some announcements. The second employee accesses the corporate database to perform some financial transactions. The third employee participates in an important live audio conference with other corporate managers in branch offices. If QoS is implemented on this network, what will be the priorities from highest to lowest of the different data types? financial transactions, audio conference, web page audio conference, financial transactions, web page audio conference, web page, financial transactions financial transactions, web page, audio conference Explain: QoS mechanisms enable the establishment of queue management strategies that enforce priorities for different categories of application data. Thus, this queuing enables voice data to have priority over transaction data, which has priority over web data. 3. What is a benefit of using cloud computing in networking? End users have the freedom to use personal tools to access information and communicate across a business network. Network capabilities are extended without requiring investment in new infrastructure, personnel, or software. Technology is integrated into every-day appliances allowing them to interconnect with other devices, making them more ‘smart’ or automated. Home networking uses existing electrical wiring to connect devices to the network wherever there is an electrical outlet, saving the cost of installing data cables. Explain: Cloud computing extends IT’s capabilities without requiring investment in new infrastructure, training new personnel, or licensing new software. These services are available on-demand and delivered economically to any device anywhere in the world without compromising security or function. BYOD is about end users having the freedom to use personal tools to access information and communicate across a business or campus network. Smart home technology is integrated into every-day appliances allowing them to interconnect with other devices, making them more ‘smart’ or automated. Powerline networking is a trend for home networking that uses existing electrical wiring to connect devices to the network wherever there is an electrical outlet, saving the cost of installing data cables. 4. What is the function of the shell in an OS? It interacts with the device hardware. It interfaces between the users and the kernel. It provides dedicated firewall services. It provides the intrusion protection services for the device. Explain: Most operating systems contain a shell and a kernel. The kernel interacts with the hardware and the shell interfaces between the kernel and the users. 5. Which connection provides a secure CLI session with encryption to a Cisco switch? a console connection an AUX connection a Telnet connection an SSH connection Explain: A CLI session using Secure Shell (SSH) provides enhanced security because SSH supports strong passwords and encryption during the transport of session data. The other methods support authentication but not encryption. 6. A network technician is attempting to configure an interface by entering the following command: SanJose(config)# ip address 192.168.2.1 255.255.255.0. The command is rejected by the device. What is the reason for this? The command is being entered from the wrong mode of operation. The command syntax is wrong. The subnet mask information is incorrect. The interface is shutdown and must be enabled before the switch will accept the IP address. Explain: The wrong mode of operation is being used. The CLI prompt indicates that the mode of operation is global configuration. IP addresses must be configured from interface configuration mode, as indicated by the SanJose(config-if)# prompt. 7. An administrator uses the Ctrl-Shift-6 key combination on a switch after issuing the ping command. What is the purpose of using these keystrokes? to restart the ping process to interrupt the ping process to exit to a different configuration mode to allow the user to complete the command Explain: To interrupt an IOS process such as ping or traceroute, a user enters the Ctrl-Shift-6 key combination. Tab completes the remainder of parameters or arguments within a command. To exit from configuration mode to privileged mode use the Ctrl-Z keystroke. CTRL-R will redisplay the line just typed, thus making it easier for the user to press Enter and reissue the ping command. 8. Refer to the exhibit. A network administrator is configuring access control to switch SW1. If the administrator uses a console connection to connect to the switch, which password is needed to access user EXEC mode? letmein secretin linevtyin lineconin Explain: Telnet accesses a network device through the virtual interface configured with the line VTY command. The password configured under this is required to access the user EXEC mode. The password configured under the line console 0 command is required to gain entry through the console port, and the enable and enable secret passwords are used to allow entry into the privileged EXEC mode. 9. On which switch interface would an administrator configure an IP address so that the switch can be managed remotely? FastEthernet0/1 VLAN 1 vty 0 console 0 Explain: Interface VLAN 1 is a virtual interface on a switch, called SVI (switch virtual interface). Configuring an IP address on the default SVI, interface VLAN 1, will allow a switch to be accessed remotely. The VTY line must also be configured to allow remote access, but an IP address cannot be configured on this line. 10. What protocol is responsible for controlling the size of segments and the rate at which segments are exchanged between a web client and a web server? TCP IP HTTP Ethernet Explain: TCP is a Layer 4 protocol of the OSI model. TCP has several responsibilities in the network communication process. It divides large messages into smaller segments which are more efficient to send across the network. It also controls the size and rate of segments exchanged between clients and servers. 11. What is an advantage to using a protocol that is defined by an open standard? A company can monopolize the market. The protocol can only be run on equipment from a specific vendor. An open standard protocol is not controlled or regulated by standards organizations. It encourages competition and promotes choices. Explain: A monopoly by one company is not a good idea from a user point of view. If a protocol can only be run on one brand, it makes it difficult to have mixed equipment in a network. A proprietary protocol is not free to use. An open standard protocol will in general be implemented by a wide range of vendors.
