#1. After a disaster has occurred, an impact assessment must be performed. Which of the following steps is the last one performed in an impact assessment?

〇:Declare the impact and consequences of the disaster.

The final step in the damage assessment is to declare the disaster. After the information from the damage assessment has been collected and evaluated, determine if the BCP actually needs to be activated. The BCP coordinator and team should determine the activation criteria before the disaster occurs.


×:Determine the cause of the disaster.

Determining the cause of the disaster is incorrect as it is the first step in the damage assessment process.


×:Identify resources that need to be replaced immediately.

Incorrect because identifying resources that need to be replaced immediately is not the last step in damage assessment.


×:Determine how long it will take to bring critical functions back online.

Incorrect because determining how long it will take to bring critical functions back online is the second-to-last step in damage assessment.

#2. One approach to alternative off-site facilities is to establish a reciprocal agreement. Which of the following describes the pros and cons of a reciprocal agreement?

〇:Can be the cheapest of the off-site options, but can create many security problems due to mixed operations.

Reciprocal agreements, also called mutual aid, mean that Company A agrees to allow Company B to use its facilities if Company B suffers a disaster, and vice versa. While this is a less expensive way to move than other off-site alternatives, it is not always the best choice. In most environments, the facility has reached its limits regarding the use of space, resources, and computing power. To allow different firms to come in and operate out of the same store could be detrimental to both firms. The stress of both companies working in the same environment can cause tremendous levels of tension. If that did not work out, it would provide the only short-term solution. Configuration management could be a nightmare, and mixing operations could result in many security problems. Reciprocal agreements have been known to work well for certain companies, such as newsprint. These firms require very specific technology and equipment that is not available through any subscription service. For most other organizations, reciprocity agreements are, at best, generally a secondary option for disaster protection.


×:Fully set up and ready to operate within a few hours is the most expensive of the off-site options.

This is a description of a hot site.


×:Inexpensive option, but takes the most time and effort to get up and running after a disaster.

Explanation for cold sites.


×:A good alternative for companies that rely on proprietary software, but regular annual testing is usually not available.

This is incorrect as it describes with respect to companies that depend on proprietary software. Having proprietary software in a shared space with other vendors is basically undesirable from the standpoint of license agreements involved.

#3. Which of the following is the average time it takes to fix and return a broken device?


Mean Time to Repair (MTTR) is the average time it takes to repair a device and return it to pre-failure production. Using a redundant array as an example, MTTR is the time it takes to replace the failed drive after the actual failure is noticed and the time the redundant array has completed rewriting the information on the new drive. Therefore, the correct answer is MTTR.



Service Level Agreements (SLA) are agreements on service quality, such as usage volume and failure recovery.


×:Hot Swap

Hot swapping refers to replacing, attaching, or disconnecting parts, cables, etc. while equipment is still in operation.



Mean Time Between Failures (MTBF) is the average time it takes for a device to fail after repair.

#4. Which of the following plans would you use to organize information about specific system hardware?

Disaster Recovery Planning (DRP) is the process of creating short-term plans, policies, procedures, and tools to enable the recovery or continuation of critical IT systems in the event of a disaster. It focuses on the IT systems that support critical business functions and how they will be restored after a disaster. For example, it considers what to do if you suffer a distributed denial of service (DDOS) attack, if your servers are compromised, if there is a power outage, etc. BCP is more focused on what should happen and does not necessarily include system requirements.

#5. We have been paying a software vendor to develop software on a custom basis, but that vendor may be out of business. Since it does not have access to the code, it cannot be retained. In what ways can the company prevent this?

〇:Software Escrow

If you do not have access to the software, but the developer may be out of business, you should plan for what to do after that out-of-business event. Software escrow means that the third party retains the source and compiled code, backup manuals, and other support materials. The agreement between the software vendor, the customer, and the third party would typically be that the customer would only have access to the source code when the vendor goes out of business and in the event of the vendor’s inability to fulfill its stated responsibilities or breach of the original agreement. The customer is protected because they can gain access to the source code and other materials through a third-party escrow agent.


×:Reciprocal Treatment Agreement

Although the term “reciprocal treatment agreement” does not exist, a close concept is mutual assistance agreements. A Mutual Assistance Agreement (MAA) is a promise to support each other in the event of a disaster by sharing facilities. There are times when you want to do something about a disaster, but you don’t have the funds to do it. In such a case, you can find a similar organization and agree to cooperate with each other in the event of a disaster.


×:Electronic Data Vault

Electronic data vaulting (e-vaulting) is the use of a remote backup service to electronically transmit backups off-site at regular intervals or when files are changed.


×:Business interruption insurance

Although the term business interruption insurance does not exist, it can be interpreted as a concept similar to insurance in the event of business interruption. Insurance is typically applied against financial risk. In this issue, software escrow is more appropriate because we want to continue access to the software.

#6. Which RAID configuration always provides redundancy?

Disk mirroring means writing the same data to multiple hard disks; a RAID (Redundant Array of Independent Disks) controller must write all data twice, requiring at least two disks. Disk striping can also be provided when parity is used, but disk striping alone cannot provide redundancy.

#7. Different levels of RAID determine the type of activity that occurs within a RAID system. Which level of RAID is associated with byte-level parity?

〇:RAID Level 3

RAID redundant arrays provide fault tolerance capability for hard drives and can improve system performance. Redundancy and speed are provided by splitting data and writing it to multiple disks, allowing different disk heads to operate simultaneously to retrieve requested information. At this time, recovery data is also created. This is called parity; if one disk fails, the parity data can be used to reconstruct the corrupted or lost information. Different levels of RAID systems experience different activities that provide fault tolerance or improved performance. RAID level 3 is a method that uses byte-level striping and dedicated parity disks.


×:RAID Level 0

Wrong because only striping occurs at level 0.


×:RAID Level 5

RAID 5 is incorrect because it uses block-level striping and interleaved parity on all disks.


×:RAID Level 10

Level 10 is incorrect because it is associated with striping and mirroring.

#8. The team should be involved in the implementation of the business continuity plan. Which team is responsible for initiating recovery of the original site?

〇:Salvage Teams

The BCP coordinator should understand the needs of the company and the types of teams that need to be developed and trained. Employees should be assigned to specific teams based on their knowledge and skill sets. Named leaders, each team must have members and the ability to direct their activities. These team leaders will be responsible not only for ensuring that team goals are met, but also for interacting with each other to ensure that each team is operating properly. The salvage team is responsible for initiating recovery of the original site. They are also responsible for backing up data from the alternate site and restoring it within the new facility, carefully terminating any unforeseen operations, and ensuring equipment and personnel are transported to the new facility.


×:Damage Assessment Team

The Damage Assessment Team is incorrect because it is responsible for determining the extent and severity of damage.


×:BCP Team

Wrong because the BCP team is responsible for creating and maintaining a business continuity plan.


×:Recovery Team

Wrong because the Recovery Team is responsible for getting an alternate site to work and to keep the environment functioning.

#9. Which of the following technologies can be used to logically combine physically disparate groups of systems and help provide immunity to failure while also helping with scalability?


Clustering is a fault-tolerant server technology in which servers are redundantly analogous. A server cluster is a group of servers that can be logically interpreted by users as one server and managed as a single logical system. Clustering provides availability and scalability. It helps to provide immunity to this group, physically distinct systems and failure and improved performance.

The problem statement is phrased in a difficult sentence. It would be difficult to derive the exact specific words from the phrase “logically coupled with a physically distinct group of systems.” In such questions, it is useful to use a process of elimination to derive options from the words that would be the point of the question. From the latter part, “technology that helps provide immunity to failure while also helping with scalability,” we can see that it is something that is both fault-tolerant and scalable. Fault tolerance alone does not narrow down the choices, but in terms of scalability features, clustering falls into this category. Therefore, the correct answer is “clustering.


×:Disk dupe

There is no such term. When presented with a seemingly incomprehensible sentence, you may consider the possibility that it is a word you probably do not know, given the time limit.



RAID (Redundant Array of Independent/Inexpensive Disks) is a technology for operating multiple hard disks as a single hard disk. It has a mechanism to improve physical redundancy by how the data to be recorded is written to the hard disks. This is not a technology system that ensures scalability.



Virtualization is a technology that makes it appear as if multiple operating systems are running on the system. Or, it is an environment that enables the construction of a real environment through simulation-like operations surrounding them. While virtualized environments allow for the construction of environments that provide fault tolerance and scalability, they do not match the operation of logically combining them with physically different groups of systems.

#10. Which of the following is NOT a phase of the Disaster Recovery Planning life cycle?

Disaster Recovery Planning includes the Mitigation, Preparedness, Response, and Recovery life cycles.

  • Mitigation: Reduces the impact and likelihood of a disaster.
  • Prepare: Create programs, procedures, and tools for response.
  • Response: follow procedures and how to respond to a disaster.
  • Recovery: re-establish basic functionality and return to a full production environment.

#11. Which of the following adequately describes parallel testing in disaster recovery testing?

〇:Ensure that some systems are executed at the alternate site.

Parallel testing compares how some systems run at the alternate site and how the results are processed at the primary site. This is to assure that systems run at the alternate site and does not affect service productivity.


×:All departments will be sent a copy of the disaster recovery plan for completeness.

This alternative is incorrect because it describes a checklist test.


×:Representatives from each department meet to validate the plan.

This option is incorrect because it describes a structured walk-through test.


×:The normal operation system is taken down.

This option is incorrect because it describes a full interruption test.

#12. Which of the following backup types does NOT clear the archive bit of the Windows system?

Archive bits are those that have been updated since the previous backup point in time. Full backups are full backups, so there is no need to be aware of where changes have occurred. Incremental backups also do not require awareness of change points because the backup portion is predetermined. Therefore, both clear the archive bit. However, differential backups do not clear the archive bit because only the changed part is known to be backed up.

#13. Which of the following plans is intended to establish a senior management or post-disaster headquarters?

〇:Continuity of Operations Plan

A continuity of operations plan (COOP) establishes senior management and post-disaster headquarters. It also outlines roles and authorities and individual role tasks.Creating a COOP begins with an assessment of how the organization operates to identify mission-critical staff, resources, procedures, and equipment. Suppliers, partners, and contractors identify other companies with whom they routinely interact and create a list of these companies. Therefore, the correct answer is the Continuity of Operations Plan.


×:Cyber Incident Response Plan

Cyber Incident Recovery is a plan for recovery from a cyber attack.


×:Crew Emergency Plan

A Crew Emergency Plan is a plan for the smooth transition of a facility’s staff to a secure environment.


×:IT Contingency Plan

A contingency plan is a plan that outlines the measures to be taken in the event of an accident, disaster, or other emergency.

#14. Which of the following is a structured walk-through test in disaster recovery testing?

〇:Representatives from each department meet and undergo validation.

Structured walk-through testing allows functional personnel to review the plan as it is fulfilled to ensure its accuracy and validity.


×:Ensures that some systems will run at alternate sites.

This is incorrect because it describes parallel testing.



×:Send a copy of the disaster recovery plan to all departments to verify its completeness.

This is incorrect because it describes a checklist test.


×:Take down the normal operation system.

This is incorrect because it describes a full interruption test.

#15. As a security administrator, you are dealing with a virus infection. One day, your antivirus application detects that a file is infected with a dangerous virus. Disinfecting that file may damage the normal file contents themselves. What action should you take?

〇:Restore the virus unpatched file version from the backup media.

The best practice is to install an unpatched, uninfected version of the file from the backup media. It is important to restore files that are known to be clean, as attempts to remove the files may corrupt them. The most important thing is not to spread the impact, but attempting to unilaterally delete files may make them unavailable for later investigation.


×:Replace the file with the file saved the previous day.

The file saved the previous day may also contain the virus.


×:Delete the file and contact the vendor.

This is an incorrect answer because the condition of this question is that if the file is deleted, the normal file content itself may be damaged.


×:Back up the data and delete the file.

This is an incorrect answer because backing up the data that contains the virus and deleting the file does not result in a clean situation.

#16. RAID systems are available in a variety of methods that provide redundancy and performance. Which ones write data divided across multiple drives?


RAID redundant arrays is a technology used for redundancy and performance. It combines multiple physical disks and aggregates them into a logical array; RAID appears as a single drive to applications and other devices. With striping, data is written to all drives. With this activity, data is split and written to multiple drives. Since multiple heads are reading and writing data at the same time, write and read performance is greatly improved.



Parity is used to reconstruct corrupted data.



Writing data to two drives at once is called mirroring.


×:Hot Swap

Hot swap refers to a type of disk found on most RAID systems. A RAID system with hot-swap disks allows the drives to be swapped out while the system is running. When a drive is swapped out or added, parity data is used to rebuild the data on the new disk that was just added.

#17. Server cluster configurations are taken for critical applications, but what functions are achieved by this configuration?

Clustering is designed for fault tolerance. It is often combined with load balancing, but they are essentially separate. Clustering can make an operation active/active. On top of that, the load balancing feature handles traffic from multiple servers. Active/passive, on the other hand, has a designated primary active server and a secondary passive server, with the passive sending keep-alives or heartbeats every few seconds.

#18. The change management process includes a variety of steps. Which of the following incorrectly describes a change management policy procedure?

〇:A change unanimously approved by the change control committee would be a step that does not require testing of the actual equipment.

This is a false choice question.

For different types of environmental changes, a structured change management process needs to be in place. Depending on the severity of the change requirement, the change and implementation may need to be presented to a change control committee. Change requests approved by the change control committee must be tested to discover any unintended consequences. This helps to demonstrate the purpose, consequences, and possible effects of the change in its various aspects. This means that just because a change has been approved by the change control board does not mean that it does not need to be tested. The change control board has mandated action on the change, and its appropriateness must be ensured by testing. Therefore, the correct answer is: “A change that is unanimously approved by the change control committee is a step that does not require testing on the actual equipment.” The result will be


×:Changes approved by the change control committee should be kept as a log of changes.

This is correct change management.


×:A rough schedule should be created during the planning phase of the change.

This is correct change management.


×:Proposed changes should be prioritized and reviewed.

This is correct change management.

#19. Which of the following is most relevant in achieving the objective of securing all evidence and notating it as information to be presented to those who verify it?

〇:Control of the processing and distribution process

An important part of the digital forensic process is to maintain a proper chain of custody of evidence.

The question structure assumes Chain of Custody (Chain of Custody) from “the purpose of securing all evidence and notating it as information to be presented to those who verify it” and selects the one that comes closest to the definition.


×:Reasonable care

Wrong because reasonable care implies performing an activity that a reasonable person would be expected to perform under similar circumstances.



Incorrect because investigation involves the proper collection of relevant data during the incident response process and includes analysis, interpretation, reaction, and recovery.


×:Motive, Opportunity, Means

Motive, Opportunity, and Means (MOM) is incorrect because it is a strategy used to understand why certain crimes were committed and by whom.

#20. John provides a weekly report to the manager outlining security incidents and mitigation procedures. If there is no incident information to put on the report, what action should he take?

〇:Send a report labeled “No output”.

If there is nothing to report (nothing to report), you need to make sure the manager is aware that the report has no information and is not only to be held accountable.


×:Send an email notifying the manager that there is nothing to report.

It is not appropriate to suddenly keep a record of the report by e-mail, since the report is normally scheduled to be reported in the operation. Realistically, wouldn’t you be more endearing to your manager if you communicated with him or her every step of the way? No, I am not asking you to do that.


×:Re-submit last week’s report and submit the date of last week’s report as this week’s date.

Delivering last week’s report does not express that nothing was reported this week.



You are required to report that nothing happened.
