I am happy to find your distinguished way of writing the post. Now you make it easy for me to understand and implement the concept.
Thank you for the post. Knowing the number of connected devices will define how many additional layers will be added to the three-tier hierarchical network design. Knowing the number of connected devices will define how many multilayer switches will be necessary at the core layer.
A high-level redundancy at the access layer may be better implemented if the number of connected devices is know. The complexity of networking infrastructure will vary according to the number of connected devices.
Choose two. Only a single NCP is allowed between the two routers. NCP terminates the link when data exchange is complete. With CHAP authentication, the routers exchange plain text passwords.
LCP tests the quality of the link. Refer to the exhibit. A network administrator is troubleshooting the OSPF network.
The What is the probable cause of this problem? There is an incorrect wildcard mask statement for network The serial interface on Router2 is down. What component is needed by the sales staff to establish a remote VPN connection? Which command can the administrator use to see the total number of active NAT translations and the number of addresses that are allocated from the NAT pool? Choose three. The same encryption keys must be manually configured on each device.
Public key encryption is a type of asymmetric encryption.

AES is an example of an asymmetric encryption protocol. CHAP Characteristics uses three-way handshake repeated challenges strong authentication encrypted passwords.
Client software is usually required to be able to access the network. Remote access VPNs support the needs of telecommuters and mobile users. End users are not aware that VPNs exists. Bind the multilink bundle to the Fast Ethernet interface.
Enable PPP encapsulation on the multilink interface. Assign the serial interfaces to the multilink bundle. The host must be connected to wired network. A site-to-site VPN must be preconfigured. A web browser must be installed on the host. A network administrator has implemented the configuration in the displayed output. What is missing from the configuration that would be preventing OSPF routing updates from passing to the Frame Relay service provider? The command to disable split horizon has not been issued.
The broadcast keyword has not been issued. An administrator is configuring NAT to provide Internet access to the inside network. After the configurtation is completed, users are unable to access the internet. What is the cause of the problem? The inside and outside interfaces are backwards. The ACL is referencing the wrong network address. What is the name given to this type of connection? On the basis of the output, which two statements about network connectivity are correct?
There is connectivity between this device and the device at This host does not have a default gateway configured. The connectivity between these two hosts allows for videoconferencing calls. There are 4 hops between this device and the device at What is the effect of these commands? The NCP will send a message to the sending device if the link usage reaches 70 percent. The PPP link will be closed down if the link quality drops below 70 percent.
The PPP link will not be established if more than 30 percent of options cannot be accepted. What kind of NAT is being configured on R1? Place the options in the following order:. Outside global. Outside local. Inside global. Inside local. The physical circuits of the Frame Relay network are shared between subscribers and there may be times when unused bandwidth is available. Bursting is enabled by the configuration of multiple subinterfaces on one physical interface.
The MIB structure for a given device includes only variables that are specific to that device or vendor. The MIB organizes variables in a flat manner.
It allows sites to use private IPv4 addresses, and thus hides the internal addressing structure form hosts on public IPv4 networks. It allows sites to use private IPv6 addresses and translates them to global IPv6 addresses. The user can select the upload and download rates based on need. The download and upload rates are the same. The upload rate is faster than the download rate.
The download rate is faster than the upload rate. Which three subinterface commands could be used to complete the configuration? When testing the connectivity, a technician finds that these PCs can access local network resources but not the Internet resources.
To troubleshoot the problem, the technician wants to initially confirm the IP address and DNS configurations on the PCs, and also verify connectivity to the local router. Which three Windows CLI commands and utilities will provide the necesary information? The following commands were issued:.
Why is the administrator not able to get any information from R1? The snmp-server community command needs to include the rw keyword. The snmp-server location command is missing. There is a problem with the ACL configuration. What will be the inside global address of packets from PC-A after they are translated by R1?
Which three events will occur as a result of the configuration shown on R1? Messages that are sent to the syslog server will be limited to levels 3 and higher.

For multiple occurrences of the same error, only the first three messages will be sent to the server. Traffic is allocated bandwidth across a single wire based on preassigned time slots. Encoding technology provides high data throughput in a minimum RF spectrum by supporting parallel data transmission.
Data capacity across a single link increases as bits from multiple sources are transmitted using interleaved slices of time.

The lead network engineer confirms connectivity between users in the branch office, but none of the users can access corporate headquarters. System logs indicate that nothing has changed in the branch office network. What should the engineer consider next to resolve this network outage? The network technician for the branch office should troubleshoot the switched infrastructure.
The server administrator in the branch office should reconfigured the DHCP server. The service provider for the branch office should troubleshoot the issue starting from the point of demarcation. Email This BlogThis! Newer Post Older Post Home. Subscribe to: Post Comments Atom.
