  • CCNA 1 v7. Which information is used by routers to forward a data packet toward its destination? A computer has to send a packet to a destination host in the same LAN. How will the packet be sent? The packet will be sent to the default gateway first, and then, depending on the response from the gateway, it may be sent to the destination host. The packet will be sent directly to the destination host. The packet will be sent only to the default gateway. What will the router do next? Which IPv4 address can a host use to ping the loopback interface? A computer can access devices on the same network but cannot access devices on other networks. What is the probable cause of this problem? The cable is not connected properly to the NIC. The computer has an invalid IP address. The computer has an incorrect subnet mask. The computer has an invalid default gateway address. Which statement describes a feature of the IP protocol?

  • What are two services provided by the OSI network layer? Choose two. Within a production network, what is the purpose of configuring a switch with a default gateway address? Hosts that are connected to the switch can use the switch default gateway address to forward packets to a remote destination. A switch must have a default gateway to be accessible by Telnet and SSH. The default gateway address is used to forward packets originating from the switch to remote networks. Explanation: A default gateway address allows a switch to forward packets that originate on the switch to remote networks. A default gateway address on a switch does not provide Layer 3 routing for PCs that are connected on that switch. A switch can still be accessible from Telnet as long as the source of the Telnet connection is on the local network. What is a basic characteristic of the IP protocol?

  • Thus, IP is connectionless and does not provide reliable end-to-end delivery by itself. IP is media independent. User data segmentation is a service provided at the transport layer. Which field in the IPv4 header is used to prevent a packet from traversing a network endlessly? The sending host sets the initial TTL value; which is decreased by one each time the packet is processed by a router. The Differentiated Services DS field is used to determine the priority of each packet. What is one advantage that the IPv6 simplified header offers over IPv4? What IPv4 header field identifies the upper layer protocol carried in the packet?
    Link: https://alaskaregional.com/service/ecg-ekg-stress-test
  • The Version field identifies the IP version. The Differential Services field is used for setting packet priority. The Identification field is used to reorder fragmented packets. Refer to the exhibit. Match the packets with their destination IP address to the exiting interfaces on the router. Not all targets are used. Packets with a destination of Because network Because a gateway of last resort exists, no packets will be dropped. What information does the loopback test provide? DHCP is working correctly. The Ethernet cable is working correctly. The device has the correct IP address on the network. What routing table entry has a next hop address associated with a destination network?

  • 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?
    Link: https://inc.com/alison-davis/these-15-questions-will-assess-your-companys-culture-and-help-you-decide-how-to-improve-it.html
  • 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?
    Link: https://pmwares.com/qbzifq/0c8bc7-snyder-cut-reddit-leaks
  • 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?

  • It has a maximum speed of Mbps. What are two features of a physical, star network topology? It is straightforward to troubleshoot. It is easy to add and remove end devices. Each end system is connected to its respective neighbor. A frame is transmitted from one networking device to another. Why does the receiving device check the FCS field in the frame? It initiates an ARP request. It broadcasts the frame out of all ports on the switch. It notifies the sending host that the frame cannot be delivered. It forwards the frame out of all ports except for the port at which the frame was received.
