David system is a network management system that allows a user to manage the resources and services through both Intranet and Internet.

It provides auto-discovering and network topology building features to facilitate in keeping an intuitive view of the IT infrastructure. The

resources, real-time monitoring, and accessibility of historical data facilitate reaction to failures. Configured interfaces for monitored devices

permit a user to focus on the most important aspects of their work.

Answer B is incorrect. dopplerVUe is a network management tool that facilitates network discovery, mapping, alerts and alarm

management, and bandwidth management system. It enables monitoring of Ping, SNMP, syslog, and WMI performance metrics. It can also be

used to monitor IPv6 devices, as well as services such as DNS, http, and email.

Answer A is incorrect. eBox is an open source distribution and web development framework. This framework is used to manage server

application configuration. It is based on Ubuntu Linux. It is projected to manage services in a computer network. The modular design of eBox

allows a user to pick and choose the services.

Answer D is incorrect. EM7 is a network monitoring system that is used to measure IT infrastructure health and performance. It is an

NMS integrated system. It is designed to help in optimizing the performance and availability of the networks, systems, and applications. It

facilitates trouble-ticketing, event management, reporting, IP management, DNS, and monitoring.

According to the scenario, you have enabled system message logging (syslog) service on all the routers that are currently working in the

network. If you want to store all the repots, important error and notification messages sent by the routers, you can store all of these in the

buffer, console, syslog server, and tty lines.

You can use buffer, if you want to store syslog messages for later analysis of the network. Buffer is the memory of the router. The syslog

messages that you have stored in the buffer are later available for the network analysis until the router is rebooted.

You can use console port of the routers to send syslog messages to the attached terminal. You can also use vty and tty lines to send syslog

messages to the remote terminal. However, the messages send through the console, vty, and tty lines are not later available for network

analysis.

You can use syslog server to store all the reports, and important error and notification messages. It is the best option to store all these

because it is easy to configure a syslog server and you can store a large volume of logs.

Note: If you have configured to run an SNMP agent, the routers send all the reports, and important error and messages in the form of SNMP

traps to an SNMP server. Using this you can store the reports and messages for a long period of time.

Answer A is incorrect. You cannot store syslog messages in the auxiliary line.

The tar -u command is used to append a tar file if the on-disk version of the tar file has a modification date more recent than its copy in the tar

archive.

Answer B is incorrect. The tar -t command is used to list the contents of an archive.

Answer D is incorrect. The tar -x command is used to extract the files from an archive.

Answer C is incorrect. The tar -c command is used to create a new archive of specified files.

The klogd and sysklogd commands can be used to intercept and log the Linux kernel messages.

A ping scanner is a tool that sends ICMP ECHO requests across a network and rapidly makes a list of responding nodes.

Internet Control Message Protocol (ICMP) is an integral part of IP. It is used to report an error in datagram processing. The Internet Protocol

(IP) is used for host-to-host datagram service in a network. The network is configured with connecting devices called gateways. When an

error occurs in datagram processing, gateways or destination hosts report the error to the source hosts through the ICMP protocol. The ICMP

messages are sent in various situations, such as when a datagram cannot reach its destination, when the gateway cannot direct the host to

send traffic on a shorter route, when the gateway does not have the buffering capacity, etc.

Answer C, A, and B are incorrect. These tools do not use ICMP to perform their functions.
