CCNA1 FINAL EXAM STUDY GUIDE part1
*What is an example of a top-level domain?* www.cisco.com cisco.com .com root.cisco.com
.com
*A user is unable to reach the web site when typing http://www.cisco.com in a web browser, but can reach the same site by typing http://72.163.4.161. What is the issue?* default gateway DHCP DNS TCP/IP protocol stack
DNS
*What are two benefits of using a layered network model? (Choose two.)* It assists in protocol design. It speeds up packet delivery. It prevents designers from creating their own model. It prevents technology in one layer from affecting other layers. It ensures a device at one layer can function at the next higher layer.
It assists in protocol design. It prevents technology in one layer from affecting other layers.
*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.
It encourages competition and promotes choices.
*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
It interfaces between the users and the kernel.
*What are two characteristics of fiber-optic cable? (Choose two.)* It is not affected by EMI or RFI. Each pair of cables is wrapped in metallic foil. It combines the technique of cancellation, shielding, and twisting to protect data. It typically contains 4 pairs of fiber-optic wires. It is more expensive than UTP cabling is.
It is not affected by EMI or RFI. It is more expensive than UTP cabling is
*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.
Network capabilities are extended without requiring investment in new infrastructure, personnel, or software.
*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
TCP
*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
The command is being entered from the wrong mode of operation.
*What is one indication that a Windows computer did not receive an IPv4 address from a DHCP server?* The computer cannot ping 127.0.0.1. Windows displays a DHCP timeout message. The computer receives an IP address that starts with 169.254. The computer cannot ping other devices on the same network with IP addresses in the 169.254.0.0/16 range.
The computer receives an IP address that starts with 169.254.
*What is a characteristic of multicast messages?* They are sent to a select group of hosts. They are sent to all hosts on a network. They must be acknowledged. They are sent to a single destination.
They are sent to a select group of hosts.
*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
VLAN 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
a network that recovers quickly when a failure occurs and depends on redundancy to limit the impact of a failure
*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
an SSH connection
*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?* audio conference, financial transactions, web page financial transactions, web page, audio conference audio conference, web page, financial transactions financial transactions, audio conference, web page
audio conference, financial transactions, web page
*What is a characteristic of UTP cabling?* cancellation cladding immunity to electrical hazards woven copper braid or metallic foil
cancellation
*Where are Cisco IOS debug output messages sent by default?* memory buffers vty lines Syslog server console line
console line
*Which two OSI model layers have the same functionality as two layers of the TCP/IP model? (Choose two.)* data link network physical session transport
network transport
*A network administrator is troubleshooting connectivity issues on a server. Using a tester, the administrator notices that the signals generated by the server NIC are distorted and not usable. In which layer of the OSI model is the error categorized?* presentation layer network layer physical layer data link layer
physical layer
*Which name is assigned to the transport layer PDU?* bits data frame packet segment
segment
*A network technician suspects that a particular network connection between two Cisco switches is having a duplex mismatch. Which command would the technician use to see the Layer 1 and Layer 2 details of a switch port?* show interfaces show running-config show ip interface brief show mac-address-table
show interfaces
*Which command can an administrator issue on a Cisco router to send debug messages to the vty lines?* terminal monitor logging console logging buffered logging synchronous
terminal monitor
*What source IP address does a router use by default when the traceroute command is issued?* the highest configured IP address on the router a loopback IP address the IP address of the outbound interface the lowest configured IP address on the router
the IP address of the outbound interface
*A network administrator is measuring the transfer of bits across the company backbone for a mission critical financial application. The administrator notices that the network throughput appears lower than the bandwidth expected. Which three factors could influence the differences in throughput? (Choose three.)* the amount of traffic that is currently crossing the network the sophistication of the encapsulation method applied to the data the type of traffic that is crossing the network the latency that is created by the number of network devices that the data is crossing the bandwidth of the WAN connection to the Internet the reliability of the gigabit Ethernet infrastructure of the backbone
the amount of traffic that is currently crossing the network the type of traffic that is crossing the network the latency that is created by the number of network devices that the data is crossing
*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
to interrupt the ping process
