It defines software processes that provide services to the physical layer. It provides the logical addressing required that identifies the device. VLAN 1.- Both commands generate the same output. On a router, the show ip route command is used to display the routing table. The netstat —s command is used to display per-protocol statistics. The tracert command is used to display the path that a packet travels to its destination. What are two functions that are provided by the network layer? Choose two. Which two statements describe features of an IPv4 routing table on a router? If there are two or more possible routes to the same destination, the route associated with the higher metric value is included in the routing table. The netstat -r command can be used to display the routing table of a router. It stores information about routes derived from the active router interfaces. If a default static route is configured in the router, an entry will be included in the routing table with source code S.
- How does the service password-encryption command enhance password security on Cisco routers and switches? It requires encrypted passwords to be used when connecting remotely to a router or switch with Telnet. It encrypts passwords that are stored in router or switch configuration files. It requires that a user type encrypted passwords to gain console access to a router or switch. It encrypts passwords as they are sent across the network. Explain: The service password-encryption command encrypts plaintext passwords in the configuration file so that they cannot be viewed by unauthorized users. Why would a Layer 2 switch need an IP address? However, when a switch is accessed remotely through the network, it must have a Layer 3 address. The IP address must be applied to a virtual interface rather than to a physical interface.
- Routers, not switches, function as default gateways. What characteristic describes identity theft? Match each description to its corresponding term. Not all options are used. A user sends an HTTP request to a web server on a remote network. During encapsulation for this request, what information is added to the address field of a frame to indicate the destination? The source device will not know the MAC address of the remote host. An ARP request will be sent by the source and will be responded to by the router. The router will respond with the MAC address of its interface, the one which is connected to the same network as the source. Data is being sent from a source PC to a destination server. Choose three. The source port field identifies the running application or service that will handle data returning to the PC. The TCP process running on the PC randomly selects the destination port when establishing a session with the server.
- UDP segments are encapsulated within IP packets for transport across the network. The UDP destination port number identifies the application or service on the server which will handle the data. TCP is the preferred protocol when a function requires lower network overhead. The TCP source port number identifies the sending host on the network. Explanation: Layer 4 port numbers identify the application or service which will handle the data. The source port number is added by the sending device and will be the destination port number when the requested information is returned.

Layer 4 segments are encapsulated within IP packets. Destination port numbers are specific ports that a server application or service monitors for requests. Match each description with the corresponding TCP mechanism. Refer to the exhibit. Which two network addresses can be assigned to the network containing 10 hosts? Your answers should waste the fewest addresses, not reuse addresses that are already assigned, and stay within the- Explanation: Well Known Ports: 0 through Registered Ports: through Refer to the exhibit. What is the problem? The entire command, configure terminal, must be used. The administrator is already in global configuration mode. The administrator must first enter privileged EXEC mode before issuing the command. Explanation: In order to enter global configuration mode, the command configure terminal, or a shortened version such as config t, must be entered from privileged EXEC mode. The administrator would need to use the enable command to move into privileged EXEC mode before entering the configure terminal command. What is a user trying to determine when issuing a ping What is a characteristic of a switch virtual interface SVI? SVIs do not require the no shutdown command to become enabled. SVIs come preconfigured on Cisco switches. These ports do not support Layer 3 IP addresses. Therefore, switches have one or more switch virtual interfaces SVIs.
- These are virtual interfaces because there is no physical hardware on the device associated with it. An SVI is created in software. The virtual interface lets you remotely manage a switch over a network using IPv4 and IPv6. Match the descriptions to the terms. Not all options are used. What happens when a switch receives a frame and the calculated CRC value is different than the value that is in the FCS field? The switch notifies the source of the bad frame. The switch drops the frame. Two network engineers are discussing the methods used to forward frames through a switch. What is an important concept related to the cut-through method of switching? The fragment-free switching offers the lowest level of latency. Fragment-free switching is the typical cut-through method of switching. Packets can be relayed with errors when fast-forward switching is used. Which two issues can cause both runts and giants in Ethernet networks?

- Vinh Nguyen 5. After an unsuccessful ping to the local router, the technician decides to investigate the router. The technician observes that the lights and fan on the router are not operational. In which layer of the OSI model is the problem most likely occurring? Physical 6. Refer to the exhibit. How many broadcast domains are shown? Three 7. However, the distance between the two hosts is further than the cabling standards allow. Choose two. What must be configured on Host B to allow it to communicate with the file server? Choose three. Host A pings Host B. What can be concluded about the source and destination addresses contained in the communication sent by Router R5 when it forwards the ping out the Ethernet interface to Host B? Which network device creates the highest amount of latency?
- The host finds that the two FCS values do not match. What action will be taken by the host? The host discards the frame. Session If the NICs are operating at Mbps, how much bandwidth is available for each computer to receive data? Based on the graphic above, which of the following occurs as each host system comes on line in the topology? The switch adds MAC address to the bridge table as each host sends a frame. Consider the networks shown in the exhibit. Host A is sending packets to host B. Which layer of the OSI model is being used when the router is making the calculated decision to determine which interface to send the packet out? Network Why would a company install a switch instead of a hub when building or expanding a corporate network? A switch provides more bandwidth by sending frames only out the port to which the destination device is attached. A hub sends the frame out all ports except the source port.

The hub and the switch are operating using factory default settings. Which hosts will receive the frame if host A transmits a broadcast frame? Workstations B, C, D, E, and the router will receive the data. An instructor in the network class has given the students the network diagram and asks the students to select the appropriate network devices. The goals are to provide a collision-free LAN environment and to provide Internet connectivity. What is the correct design? Replace Box 1 with a hub and Box 2 with a router. Replace Box 1 with a router and Box 2 with a bridge.- Replace Box 1 with a router and Box 2 with a Layer 2 switch. Replace Box 1 with a bridge and Box 2 with a Layer 2 switch. A network administrator attempts to increase the available bandwidth for workstation A by setting the NIC to full-duplex mode. After the configuration is changed, there are increased collisions and errors occurring. Why is this occurring in the network? The switch will not support full-duplex mode. The hub will be continually producing a jam signal. The cabling will not support bidirectional transmissions.
- A network administrator is testing a connectivity issue in the network. A ping command on host A to The NIC link indicator on host A is illuminated. Temporarily, the administrator removes the cable from host A and uses the LAN cable from host B to connect from host A to port 1 on the switch. While using the substitute cable, host A can communicate with host C and RouterA. At which layer of the OSI model was the problem occurring? How many broadcast domains are shown in the diagram? A collision has occurred on an Ethernet network. When the collision is detected, the hosts stop transmission immediately. When the collision is detected, the hosts stop transmission after eight microseconds. When the backoff period expires, the hosts involved in the collision have priority to transmit. Which of the following devices extend a collision domain?
- What should a network administrator consider when migrating to Gigabit Ethernet architecture from Fast Ethernet? Existing NICs must support half-duplex mode. Existing UTP wiring must be replaced with fiber. Existing network topology must support shared media. The local host is also using the SNMP protocol to report the system status to the network management system. Which statement describes the communication from the host? The network administrator visually examined the cables the technician terminated. Some of the cables have connectors as shown in the exhibit. What should the network administrator explain to the technician about the cables?
- Both cables are acceptable. The cable in Graphic A should be used in the more critical network segments. The cable in Graphic A is preferred because it will be easier to crimp the connector.

- 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. 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? Thus, this queuing enables voice data to have priority over transaction data, which has priority over web data. 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.
