A grandfather-father-son (GFS) backup rotation scheme would best meet this requirement. GFS typically involves daily (son), weekly (father), and monthly (grandfather) backups, allowing for recovery to any point within the last 30 days while also providing longer-term backups.

The organization should implement an active-active cluster configuration. In an active-active setup, all nodes in the cluster are simultaneously processing requests, which provides both load balancing and high availability. If one node fails, the others continue to operate, maintaining service availability.

The organization is defining their Recovery Time Objective (RTO) and Recovery Point Objective (RPO). The RTO of 2 hours represents the maximum tolerable length of time that the systems can be down after a disaster. The RPO of 15 minutes represents the maximum amount of data loss that can be tolerated in the event of a disaster.

A hot site would best meet these requirements. A hot site is a fully equipped alternate data center with up-to-date copies of data. It can typically be operational within minutes to hours, which aligns with the organization’s 4-hour recovery time objective (RTO) and 1-hour recovery point objective (RPO).

Granular recovery technology would best meet this requirement. It allows for the recovery of individual files or objects from within a VM backup without the need to restore the entire virtual machine, providing both flexibility and efficiency in the recovery process.

Continuous Data Protection (CDP) would best meet this requirement. CDP continuously captures changes to data and allows for recovery to any point in time, minimizing potential data loss to nearly zero.

An incremental backup strategy would best meet these requirements. Incremental backups only copy data that has changed since the last backup, whether it was a full or incremental backup. This minimizes the backup window while still allowing for relatively quick restores by applying the last full backup and all subsequent incremental backups.

A granular backup solution would best meet this requirement. Granular backups allow for the recovery of individual files, folders, or other specific items without the need to restore the entire backup. This provides flexibility and efficiency in the recovery process.

The company is trying to define their Recovery Time Objective (RTO). RTO is the maximum tolerable length of time that a computer, system, network, or application can be down after a failure or disaster occurs. In this case, the RTO would be 4 hours for critical systems.

DNS failover would best accomplish this. It automatically updates DNS records to redirect traffic to a backup site when the primary site becomes unavailable, ensuring continuous availability of the website.

The primary purpose of a load balancer is to distribute network traffic across multiple servers. This improves the efficiency of resource utilization, maximizes throughput, minimizes response time, and ensures that no single server becomes overwhelmed with too many requests.

An active-active configuration would best meet this requirement. In an active-active setup, multiple servers are running simultaneously, sharing the workload. If one server fails, the others continue to operate, maintaining service availability without any downtime.

This scenario describes an active-passive failover configuration. In this setup, the primary server actively handles requests while the secondary server remains on standby. When the primary fails, there’s a brief outage as the secondary server takes over, which is characteristic of active-passive configurations.

An incremental backup strategy would best meet their needs. Incremental backups only copy data that has changed since the last backup, whether it was a full or incremental backup. This minimizes both the backup window and storage space required, making it ideal for businesses with limited resources.

RAID 10 (also known as RAID 1+0) would best meet these requirements. RAID 10 combines the mirroring of RAID 1 with the striping of RAID 0, providing both high performance through striping and fault tolerance through mirroring.

This scenario describes an active-passive failover configuration. In this setup, the primary server actively handles requests while the secondary server remains on standby. When the primary fails, there’s a brief outage as the secondary server takes over, which is characteristic of active-passive configurations.

RAID 10 (also known as RAID 1+0) would best meet these requirements. RAID 10 combines the mirroring of RAID 1 with the striping of RAID 0, providing both improved performance through striping and data redundancy through mirroring.

A granular backup solution would best meet this requirement. Granular backups, also known as item-level backups, allow for the recovery of individual items (like emails or folders) from within a full backup without the need to restore the entire Exchange server. This provides flexibility and efficiency in the recovery process.

A load balancer would best meet this requirement. A load balancer can distribute incoming web traffic across multiple servers, ensuring that no single server becomes overwhelmed. This improves the application’s availability, performance, and scalability.

The RAID 5 array is operating in a degraded state. RAID 5 can continue to function with one failed drive, but it is operating with reduced performance and no fault tolerance until the failed drive is replaced and the array is rebuilt.

While server virtualization offers many benefits for business continuity and disaster recovery, it does not inherently provide better physical security. Physical security measures are still necessary regardless of whether servers are physical or virtual.

Load balancing would best accomplish this. A load balancer automatically distributes incoming network traffic across multiple servers, improving the efficiency of resource utilization, maximizing throughput, minimizing response time, and ensuring that no single server becomes overwhelmed.

The company should implement a warm site. A warm site is a backup facility that contains pre-configured hardware and software, but may not have live data. It can typically be made operational within 24-72 hours, which aligns with the company’s 24-hour requirement.

Synchronous replication would best meet this requirement. It ensures that data is written to both the primary and secondary sites simultaneously before the write operation is considered complete. This provides real-time data mirroring between geographically dispersed sites with minimal latency.

This configuration is best described as a highly available system. By using multiple mail servers behind a load balancer, the company is implementing both load distribution and redundancy. If one server fails, the others can continue to handle requests, ensuring continuous availability of the email service.
