  • Install a new hard disk as the primary disk, then make the current disk a slave. Explanation: Always perform a backup before beginning any troubleshooting. Even though the data was backed up to a different partition, the data is still on the same hard drive. If the drive crashes, the data might not be recoverable. What is the next step after a possible solution is implemented during a troubleshooting process? Test another possible solution. Identify other possible causes for the problem. Document the cause and the solution for the problem. Verify the full system functionality and apply maintenance procedures. Explanation: After the repairs have been completed, continue the troubleshooting process by verifying full system functionality and implementing any needed preventive measures. After a technician tests a theory of probable causes, what two actions should the technician take if the testing did not identify an exact cause? Establish a new theory of probable causes. Randomly replace components one at a time until the problem is solved.

  • Choose two. The dialer pool command is applied to the Ethernet interface to link it to the dialer interface. The Ethernet interface does not have an IP address. The PPP configuration is on the dialer interface. An MTU size of bytes is configured on the Ethernet interface. An Ethernet link supports a number of data link protocols. Encapsulating Ethernet frames within PPP frames is an efficient use of bandwidth. CHAP enables customer authentication and accounting. It provides secure transport of private information over public networks, such as the Internet. It is a Cisco software solution for building multiple VPNs in an easy, dynamic, and scalable manner. It allows the creation of dynamically allocated tunnels through a permanent tunnel source at the hub and dynamically allocated tunnel destinations at the spokes. Which two statements describe a remote access VPN?

  • It connects entire networks to each other. It may require VPN client software on hosts. It is used to connect individual hosts securely to a company network over the Internet. It requires static configuration of the VPN tunnel. A router labeled R1 at the edge of this cloud connects through a serial interface labeled The serial interface on R2 is labeled Refer to the exhibit. Which two configurations will allow router R1 to establish a neighbor relationship with router R2? R1 config router bgp R1 config-router neighbor

  • What three things can the administrator verify? Choose three. Address translation is working. Three addresses from the NAT pool are being used by hosts. The name of the NAT pool is refCount. A standard access list numbered 1 was used as part of the configuration process. Two types of NAT are enabled. One port on the router is not participating in the address translation. The show ip nat statistics, show ip nat translations, and debug ip nat commands are useful in determining if NAT is working and and also useful in troubleshooting problems that are associated with NAT. NAT is working, as shown by the hits and misses count. Because there are four misses, a problem might be evident.

  • The standard access list numbered 1 is being used and the translation pool is named NAT as evidenced by the last line of the output. Which destination do Cisco routers and switches use by default when sending syslog messages for all severity levels? Which requirement should be checked before a network administrator performs an IOS image upgrade on a router? The desired IOS image file has been downloaded to the router. There is sufficient space in flash memory. The old IOS image file has been deleted. The FTP server is operational. Before an upgrade process starts, the user must make sure that there is sufficient space in the flash to host the new IOS image file. Instead, a TFTP server is used. The boot system command is a global configuration command that allows the user to specify the source for the Cisco IOS Software image to load.

  • How can the use of VPNs in the workplace contribute to lower operating costs? High-speed broadband technology can be replaced with leased lines. VPNs require a subscription from a specific Internet service provider that specializes in secure connections. New headers from one or more VPN protocols encapsulate the original packets.

  • Packets are disguised to look like other types of traffic so that they will be ignored by potential attackers. A dedicated circuit is established between the source and destination devices for the duration of the connection. Which two statements describe a remote access VPN? Choose two. It connects entire networks to each other. It is used to connect individual hosts securely to a company network over the Internet. Which is a requirement of a site-to-site VPN? It requires the placement of a VPN server at the edge of the company network. It requires hosts to use VPN client software to encapsulate traffic.

  • Which two scenarios are examples of remote access VPNs? A toy manufacturer has a permanent VPN connection to one of its parts suppliers. All users at a large branch office can access company resources through a single VPN connection. A mobile sales agent is connecting to the company network via the Internet connection at a hotel. An employee who is working from home uses VPN client software on a laptop in order to connect to the company network.

  • The correct configuration on R1 is: router ospf 10 network What are two reasons that will prevent two routers from forming an OSPFv2 adjacency? Choose two. OSPF network types do not match. There is a missing or incorrect OSPF network command. Mismatched IOS versions, the use of private IP addresses, and different types of interface ports used on a switch are not causes for an OSPF adjacency failing to form between two routers. What does a Cisco router use automatically to create link-local addresses on serial interfaces when OSPFv3 is implemented? Single area OSPFv3 has been enabled on a router via the ipv6 router ospf 20 command.

  • What is the metric that is used by OSPF? OSPF calculates cost inversely to the bandwidth of an interface. The higher the interface bandwidth, the lower the cost of the interface. What function is performed by the OSPF designated router? What is used to create the OSPF neighbor table? When a network engineer is configuring OSPFv3 on a router, which command would the engineer issue immediately before configuring the router ID? This address is not included in the routing table and is not defined by the network command. If a router ID that is configured through the router-id command is not available, OSPF routers next use the highest IP address available on a loopback interface, as loopbacks used as router IDs are also not routable addresses.

  • Lacking either of these alternatives, an OSPF router will use the highest IP address from its active physical interfaces. Match the OSPF state with the order in which it occurs. Not all options are used. Match each OSPF packet type to how it is used by a router. Match the information to the command that is used to obtain the information. Older Version Refer to the exhibit. When the auto-summary command is issued on R3, which two summary networks will be advertised to the neighbors?

  • VPNs require a subscription from a specific Internet service provider that specializes in secure connections. Two corporations have just completed a merger. The network engineer has been asked to connect the two corporate networks without the expense of leased lines. Which solution would be the most cost effective method of providing a proper and secure connection between the two corporate networks? Choose two. A toy manufacturer has a permanent VPN connection to one of its parts suppliers. All users at a large branch office can access company resources through a single VPN connection. A mobile sales agent is connecting to the company network via the Internet connection at a hotel. An employee who is working from home uses VPN client software on a laptop in order to connect to the company network.

  • If the question is not here, find it in Questions Bank. We will update answers for you in the shortest time. Thank you! We truly value your contribution to the website. Refer to the exhibit. Based on the command output shown, what is the status of the EtherChannel? The EtherChannel is down as evidenced by the protocol field being empty. Configuring the EtherChannel using the channel-group 1 mode on command will cause the Protocol field in the command output to be empty. A network engineer is troubleshooting host connectivity on a LAN that uses a first hop redundancy protocol. Which IPv4 gateway address should be configured on the host? What is the purpose of HSRP? It provides a continuous network connection when a router fails. It prevents malicious hosts from connecting to trunk ports. It enables an access port to immediately transition to the forwarding state.
    Link: http://web.mit.edu/6.891/www/lab/paml.html
  • HSRP is a first hop redundancy protocol and allows hosts to use multiple gateways through the use of a single virtual router. What is the problem? The switch ports have to be configured as access ports with each port having a VLAN assigned. The interface port-channel number has to be different on each switch. The switch ports were not configured with speed and duplex mode. Interfaces in an EtherChannel have to operate at the same speed and in the same duplex mode.

  • Assign affected interfaces to an unused VLAN. Before configuring EtherChannel, the interfaces used should be shut down so that any incomplete configuration will not cause activity on the link. Which statement describes an EtherChannel implementation? EtherChannel operates only at Layer 2. A trunked port can be part of an EtherChannel bundle. PAgP cannot be used in conjunction with EtherChannel. EtherChannel can be configured as a Layer 2 bundle or a Layer 3 bundle. Configuring a Layer 3 bundle is beyond the scope of this course. If a trunked port is a part of the EtherChannel bundle, all ports in the bundle need to be trunk ports and the native VLAN must be the same on all of these ports.
