(Select three.) The interface is dropping incoming packets. One cyclic redundancy check error has occurred. No input or output errors have occurred. The interface is running in half-duplex mode. There have been no interface resets. Several collisions have occurred.

You have a WAN link that connects two sites. The WAN link is supposed to provide 1.5 Mbps of bandwidth. You want to perform a test to see the actual bandwidth of the link. Which tool should you use? Load tester Packet sniffer Throughput tester Baseline
Throughput tester
You just deployed a new Cisco router that connects several network segments in your organization. The router is physically located in a server room that requires and ID card to gain access. You backed up the router configuration to a remote location in an encrypted file. You access the router configuration interface from your notebook computer using a Telnet client with a username of admin and a password of admin. You used the MD5 hashing algorithm to protect the password. What should you do to increase the security of this device? (select two)
Use an SSH client to access the router configuration. Change the default administrative username and password.
You are the network administrator for a growing business. When you were hired, the organization was small, and only a single switch and router were required to support your users. During this time, you monitored log messages from your router and switch directly from each device's console. The organization has grown considerably in recent months. Now you manage eight individual switches and three routers. It's becoming more and more difficult to monitor these devices and stay on top of issues in a timely manner. What should you do? Consolidate network resources down to one or two switches. Use syslog to implement centralized logging. Hire additional resources to help monitor and manage your network infrastructure. Use a remote access utility such as SSH to access router and switch consoles remotely.
Use syslog to implement centralized logging.

Your company is a small start-up that has leased office space in a building shared by other businesses. All businesses share a common network infrastructure. A single switch connects all devices in the building to the router that provides internet access. You would like to make sure that your computers are isolated from computers used by other companies. Which feature should you request to have implemented?
VLAN
You are adding a new rack to your data center, which will house two new blade servers and a new switch. The new servers will be used for file storage and a database server. The only space you have available in the data center is on the opposite side of the room from your existing rack, which already houses several servers, a switch, and a router. You plan to configure a trunk port on each switch and connect them with a cross-over UTP plenum cable that will run through the suspended tile ceiling of the data center. To provide power for the new devices, you had an electrician install several new 20-amp wall outlets near the new rack. Each device in the rack will be plugged directly into one of these new wall outlets. What is wrong with this configuration? (Select two.) You should implement redundant power supplies for the network devices. You should implement a UPS between the wall outlet and the network devices. You should not connect networking equipment to a 20-amp wall circuit. You should not run a plenum cable through a suspended tile ceiling. You must use a straight-through cable to connect the two switches together.
You should implement redundant power supplies for the network devices. You should implement a UPS between the wall outlet and the network devices.
In which of the following situations would you use port security?
You want to restrict the devices that could connect through a switch port
Which of the following are improvements to SNMP that are included within SNMP version 3? (Select two)
a. Authentcation for agents and managers b. Encryption of SNMP messages
You provide IT support under contract for a dentists office. The office has a limited number of wireless clients, so a simple wireless router is used to profide WIFI access. On your latest visit, you check the manufactures website and discover that a update has been released by the wireless router manufacture. You decide to download and install the update. Click the option you should use in the wireless routers configuration interface to prepare the device for update.
