Because of an unexplained slowdown on your network, you decide to install monitoring software on several key network hosts to locate the problem. You will then collect and analyze the data from a central network host.

Which protocol will the software use to detect the problem?

• Configure permissions on the log files to prevent access.

• Take a hash of the log files.

• Use Syslog to send log entries to another server.

Over the past few days, a server has gone offline and rebooted automatically several times. You would like to see a record of when each of these restarts occurred.

Which log type should you check?

• Firewall

• System

• Performance

• Security

Some users report that frequent system crashes have started happening on their workstations. Upon further investigation, you notice that these users all have received a recent update to the same application. Where would you go to conduct a root cause analysis?

• Network log

You want to identify the traffic that is generated and sent through a network by a specific application on a device.  Which tool should you use?

• TDR

• Toner probe

• Protocol analyzer

You decide to use a packet sniffer to identify the type of traffic sent to a router. You run the packet sniffing software on a device that's connected to a hub with three other computers. The hub is connected to a switch that's connected to the router. When you run the software, you see frames addressed to the four workstations but not to the router.

Which feature should you configure on the switch?

• Spanning Tree Protocol

• Bonding

• Promiscuous mode

• Port mirroring

Which of the following ensures that power is supplied to a server or device during short power outages?
