What's the optimal recommended backup storage strategy?On-site backups Off-site backups A combination of on- and off-site backups Tape backups

A combination of on- and off-site backups

Which of these are common backup tools you might consider when designing a backup solution? Check all that apply. Backup and Restore Regedit Rsync Time Machine

Backup and Restore Microsoft provides a first-party solution called Backup and Restore. Backup and Restore supports multiple modes including complete, incremental, and differential backups. Rsync Rsync is commonly used as a backup tool. It can be used for simple automated backups, and supports compression and SSH. Its main function is transfering files between computers.

Time Machine Apple's first-party backup software is called Time Machine. Time Machine mainly supports an incremental backup mode.

What options are available for storing backups, physically? On-site only Off-site only Both on-site and off-site

Both on-site and off-site

The unthinkable happens and disaster strikes, crippling your network. You implement your disaster plan, but it doesn't go smoothly. You decide to investigate. What is a commom term in the IT community for this investigation? After-outage analysis Recovery inspection probe Post-disaster inquiry Post-mortem

Post-mortem

A disaster recovery plan is a collection of documented procedures and plans on how to react and handle an emergency or disaster scenario from an operational perspective. What are important elements of a disaster recovery plan? Check all that apply. Disciplinary measures Preventative measures . Corrective or recovery measures Detection measures Detection measures are intended to alert you and your team that a disaster has occurred that can impact operations.

Preventative measures Preventative measures cover any procedures or systems in place that will proactively minimize the impact of a disaster, like regular backups and redundant systems. Anything that's done before an actual disaster that's able to reduce the overall downtime of the event is considered preventative. Corrective or recovery measures Corrective or recovery measures are those enacted after a disaster has occurred. These measures involve steps like restoring lost data from backups, or rebuilding and reconfiguring systems that were damaged. Detection measures are intended to alert you and your team that a disaster has occurred that can impact operations.

Common concerns with backups are disk failure, lack of redundancy, and the necessity of future growth of disk capacity. Which backup method adresses these concerns and has multiple levels of use depending on how you want to prioritize features like performance, capacity, or reliability? Incremental backup Complete backup RAID array

RAID array

Which backup method saves copies of all important files and data at each backup? Incremental Differential Raid Array Complete backup

Raid Array

You are performing a network risk assessment to develop your disaster recovery plan. Which of these are examples of corrective or recovery measures? Check all that apply. Rebuilding and reconfiguring services Hardware repair and replacement . Restoring data from backup Redundancy solutions

Rebuilding and reconfiguring services Hardware repair and replacement . Restoring data from backup

How can you verify that your disaster recovery plan will be effective? Through thorough testing By waiting for a disaster Through disaster simulations

Through thorough testing Testing various aspects of your recovery plan will ensure that the documented procedures will work as they're designed. This testing can be accomplished by simulating disasters and having teams run through documented Through disaster simulations Testing various aspects of your recovery plan will ensure that the documented procedures will work as they're designed. This testing can be accomplished by simulating disasters and having teams run through documented procedures.

What are good reasons to do yearly disaster recovery testing? Check all that apply. To create downtime To identify additional vulnerabilities To allow others with the right access to restore operations To be prepared for all possible snags or problems potential problems.

To identify additional vulnerabilities It's easy to miss things. If you discover a potential problem that could lead to data loss during recovery scenario testing, you will have the chance to fix the problem before any data is actually lost. To allow others with the right access to restore operations Restoration procedures should be documented and accessible, so that anyone with the right access can restore operations when needed. If you aren't available, someone will have to restore operations! To be prepared for all possible snags or problems You don't want to find out that you've missed a step or somehow rendered your backups invalid! Yearly recovery scenario testing will help pinpoint potential problems.

What's the purpose of a post-mortem report? To learn from mistakes To test systems To identify those in the wrong To assign legal liability

To learn from mistakes

When planning a backup strategy, ideally one needs to prioritize important data and only back up what is absolutely necessary for operations. Assuming storage limitations, which of these is LEAST important to back up? Databases User downloads Emails Financial spreadsheets
