Quorum Level-1 Training Assessment

Explanation
Quorum is built on Hyper Converged Infrastructure means that the Quorum system is constructed using a hyper-converged infrastructure (HCI). HCI combines storage, computing, and networking resources into a single system, making it easier to manage and scale. By stating "Yes" as the answer, it confirms that Quorum is indeed built on HCI.

Explanation
The correct answer is "HQ is in US and developed customized solutions for US Army." This answer is correct because it states that the headquarters of the company is located in the US and that they developed customized solutions specifically for the US Army. This indicates that the company is based in the US and focuses on providing tailored solutions for the US Army's needs.

Explanation
Backup and business continuity are not the same. Backup refers to the process of creating copies of data and storing them in a separate location to protect against data loss. On the other hand, business continuity refers to the ability of a business to continue its operations in the event of a disruption or disaster. While backup is a part of business continuity strategy, it is not the same as business continuity itself. Business continuity encompasses a wider range of measures, including disaster recovery planning, redundancy, and resilience.

Explanation
The question asks if quorum is a software-based solution. The correct answer is "No" because quorum refers to the minimum number of members required to be present in order to make a decision or take action. It is not a software-based solution, but rather a concept or requirement in decision-making processes.

Explanation
Hardware failure and ransomware attacks are considered the most serious disasters because they can have severe consequences for individuals and organizations. Hardware failure refers to the failure of computer components such as hard drives, power supplies, or motherboards, which can result in data loss and system downtime. On the other hand, ransomware attacks involve malicious software that encrypts files and demands a ransom for their release. These attacks can lead to the loss of sensitive data, financial loss, and disruption of operations. Both hardware failure and ransomware attacks can have significant financial and operational implications, making them highly serious disasters.

Explanation
Software-based backup/replication software faces challenges due to multiple components required for its functioning. This means that there are several interconnected parts that need to work together seamlessly, which can lead to complexity and potential issues.

Another challenge is the high vulnerability of software-based backup/replication software to ransomware attacks. Since these software solutions rely on the Windows operating system, which is a common target for ransomware attacks, there is a risk of data loss or corruption if proper security measures are not in place.

Testing is also mentioned as a challenge, although the context is not clear. It could refer to the need for thorough testing of the software to ensure its reliability and effectiveness in backing up or replicating data.

Overall, the challenges with software-based backup/replication software include the requirement for multiple components, vulnerability to ransomware attacks, and the importance of rigorous testing.

Explanation
The 3-2-1 rule is the best practice for setting up backups. It states that you should have at least three copies of your data, stored on two different types of media, with one copy stored offsite. This approach ensures redundancy and protection against data loss in case of hardware failure, natural disasters, or other unforeseen events. By following the 3-2-1 rule, you can maximize the chances of recovering your data and minimize the risk of permanent data loss.

Explanation
Quorum offers 25000 IOPs.

Explanation
Quorum uses the Zeta File System to manage the storage.

Explanation
The RPO (Recovery Point Objective) in Quorum refers to the maximum acceptable amount of data loss that an organization is willing to tolerate during a disaster recovery event. In this context, the correct answer of 15 minutes suggests that the organization is willing to accept a maximum data loss of 15 minutes in the event of a failure or disaster. This means that the organization aims to have backups or replication mechanisms in place to ensure that data is recovered or restored within 15 minutes of a failure.

Explanation
The RTO (Recovery Time Objective) in Quorum refers to the maximum acceptable downtime for a system or service after a disruption or failure. In this case, the correct answer is 2 minutes, indicating that the system or service should be recovered and fully operational within 2 minutes of a failure. This suggests that Quorum aims to provide a quick and efficient recovery process to minimize any potential disruptions or downtime.

Explanation
It is not necessary to shutdown the production server for testing the servers in quorum. Testing can be done on separate test servers or by creating a testing environment that does not interfere with the production server. Shutting down the production server can cause downtime and disrupt normal operations, so it is not recommended unless absolutely necessary.
