Which of the following are backed up during an incremental backup?

Only files that are new since the last full or incremental backup.

Your disaster recovery plan (DRP) calls for backup media to be stored at a different location. The location is a safe deposit box at the local bank. Because of this, the disaster recovery plan specifies that you must choose a method that uses the least amount of backup media but also allows you to quickly back up and restore files. Which backup strategy would BEST meet the DRP's specifications?

Perform a full backup once per week and a differential backup the other days of the week.

Perform a full backup each day of the week.

Perform a full backup once per month and an incremental backup the other days of the month.

Perform a full backup once per week and an incremental backup the other days of the week.

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 crossover UTP plenum cable that will run through the suspended tile ceiling in 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 on the rack will be plugged directly into one of these new wall outlets. What is wrong with this configuration? (Select two.)

You should implement a UPS between the wall outlet and the network devices.

You should implement redundant power supplies for the network devices.

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 not connect networking equipment to a 20-amp wall circuit.

Which of the following is true about processor performance?

A healthy system's CPU utilization should average around 40%.

If a processor utilization is consistently high, your system is performing well.

Processor utilization is the amount of time the processor spends on idle tasks.

Utilization spikes as long as an application is open.

You want to make sure that the correct ports on a firewall are open or closed. Which document should you check?

Intermediate distribution frame

Which of the following improvements to SNMP are included in version 3? (Select two.)

Agent and manager authentication

SNMP data transfer through SFTP

Which of the following defines an Acceptable Use Agreement?

An agreement that identifies the employees' rights to use company property, such as internet access and computer equipment, for personal use.

A legal contract between the organization and the employee that specifies that the employee is not to disclose the organization's confidential information.

An agreement that outlines the organization's monitoring activities.

An agreement that prohibits an employee from working for a competing organization for a specified time after the employee leaves the organization.

Which of the following pieces of information are you MOST likely to find in a policy document?

A requirement for using encrypted communications for web transactions

The IP address assigned to a router interface

Steps for completing and validating nightly backups

Average performance statistics for a router

What is the definition of latency?

The speed at which data packets travel from source to destination and back.

The percentage of available bandwidth being used.

The percentage of time that a disk subsystem reads from and writes to a disk.

Which of the following describe a system image backup?

A system image contains everything on the system volume, including the operating system, installed programs, drivers, and user data files.

A system image does not include operating system files, program files, encrypted files, files in the Recycle Bin, user profile settings, or temporary files.

A system image includes only specified files and folders backed up to a compressed file.

A system image only contains the operating system, installed programs, drivers, and user profile settings.

What is the definition of bandwidth?

The amount of data that can be transferred from one place to another in a specific amount of time.

The speed at which packets travel from source to destination and back.

The condition that occurs when a system is unable to keep up with the demands placed on it.

Which of the following information are you MOST likely to find in a procedure document?

Details on how to test and deploy patches

A record of the repairs made to a specific device

An inventory of the hardware components inside a specific device

The relationship of routers to other routers on the network

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 an ID card for access. You backed up the router configuration to a remote location with an encrypted file. You access the router configuration interface from your notebook computer using a Telnet client with the username admin and the password admin. You used the MD5 hashing algorithm to protect the password. What else should you do to increase the security of this device? (Select two.)

Change the default administrative username and password.

Use an SSH client to access the router configuration.

Use encrypted Type 7 passwords.

Use a web browser to access the router configuration using an HTTP connection.

Use TFTP to back up the router configuration to a remote location.

In addition to performing regular backups, what must you do to protect your system from data loss?

Regularly test restoration procedures.

Write-protect all backup media.

Restrict restoration privileges to system administrators.

Store the backup media in an on-site fireproof vault.

Why should you store backup media off site?

To prevent the same disaster from affecting both the network and the backup media

To reduce the possibility of theft

To comply with government regulations

To make the restoration process more efficient

You are concerned that an attacker can gain access to your web server, make modifications to the system, and alter the log files to hide his or her actions. Which of the following actions would BEST protect the log files?

Use Syslog to send log entries to another server.

Configure permissions on the log files to prevent access.
