Is referred to as stripe of mirrors, i.e., a combination of RAID 1 (disk mirroring) and RAID 0 (disk striping) 3. Requires a minimum of 5 drives to implement 4. Offers increased performance and fault tolerance (failure of one drive in each mirrored pair of disk drives does not destroy the array) 5. Requires a minimum of 3 drives to implement 6. Continues to operate in case of failure of more than 2 drives 7. Is referred to as stripe of mirrors, i.e., a combination of RAID 1 (disk striping) and RAID 0 (disk mirroring)

1. Requires a minimum of 4 drives to implement 2. Is referred to as stripe of mirrors, i.e., a combination of RAID 1 (disk mirroring) and RAID 0 (disk striping) 3. Offers increased performance and fault tolerance (failure of one drive in each mirrored pair of disk drives does not destroy the array)

Hardware RAID Level 1: (Select 3 answers) 1. Requires at least 2 drives to implement 2. Is also known as disk striping 3. Offers improved performance in comparison to RAID 0 4. Requires at least 3 drives to implement 5. Offers improved reliability by creating identical data sets on each drive (failure of one drive does not destroy the array as each drive contains identical copy of the data) 6. Is also referred to as disk mirroring

1. Requires at least 2 drives to implement 2. Offers improved reliability by creating identical data sets on each drive (failure of one drive does not destroy the array as each drive contains identical copy of the data) 3. Is also referred to as disk mirroring

Hardware RAID Level 5: (Select 3 answers) 1. Requires at least 2 drives to implement 2. Continues to operate in case of failure of more than 1 drive 3. Is also known as disk striping with double parity 4. Requires at least 3 drives to implement 5. Offers increased performance and fault tolerance (single drive failure does not destroy the array and lost data can be recreated by remaining drives) 6. Requires at least 4 drives to implement 7. Is also known as disk striping with parity

1. Requires at least 3 drives to implement 2. Offers increased performance and fault tolerance (single drive failure does not destroy the array and lost data can be re-created by the remaining drives) 3. Is also known as disk striping with parity

Hardware RAID Level 6: (Select 3 answers) 1. Is also known as disk striping with parity 2. Requires at least 4 drives to implement 3. Offers increased performance and fault tolerance (failure of up to 2 drives does not destroy the array and lost data can be recreated by the remaining drives) 4. Requires at least 3 drives to implement 5. Is also known as disk striping with double parity 6. Continues to operate in case of failure of more than 2 drives 7. Requires at least 5 drives to implement

1. Requires at least 4 drives to implement 2. Offers increased performance and fault tolerance (failure of up to 2 drives does not destroy the array and lost data can be re-created by the remaining drives) 3. Is also known as disk striping with double parity

Hardware RAID Level 0: (Select all that apply) 1.Requires a minimum of 2 drives to implement 2. Is also known as disk striping 3. Decreases reliability (failure of any disk in the array results in the loss of all data in the array) 4. Is also referred to as disk mirroring 5. Offers less volume capacity in comparison to RAID 1 6. Requires at least 3 drives to implement 7. Is suitable for systems where performance has higher priority than fault tolerance 8. Offers improved reliability by creating identical data sets on each drive (failure of one drive not destroy the array as each drive contains identical copy of the data)

1.Requires a minimum of 2 drives to implement 2.Is also known as disk striping 3.Decreases reliability (failure of any disk in the array results in the loss of all data in the array) 4.Is suitable for systems where performance has higher priority than fault tolerance

What is the name of the a U.S. government initiative that provides a set of procedures and plans that an organization can implement to ensure continued performance of its essential functions during unexpected events? SLA COOP RPO BIA

COOP (Continuity of Operations Plan)

Which alternate site is the least expensive to implement? Cold site Mirror site Warm site Hot site

Cold site

Which of the answers listed below refers to the primary function of load balancing? Maintains identical copies of data across multiple servers to enhance data availability and reliability Distributes workload across multiple servers for improved performance Groups servers together to provide high availability and fault tolerance Distributes content geographically across multiple servers to improve performance, reduce latency, and handle high volumes of traffic

Distributes workload across multiple servers for improved performance.

The process of switching to a redundant or standby system upon detecting a disruption in the primary system is called: Fail over Multipath Load balancing Parallel processing

Failover

Which of the following is the primary function of clustering? 1. Distributes content geographically across multiple servers to improve performance, reduce latency, and handle high volumes of traffic 2. Groups servers together to provide high availability and fault tolerance 3. Maintains identical copies of data across multiple servers to enhance data availability and reliability 4. Distributes workload across multiple serves for improved performance

Groups servers together to provide high availability and fault tolerance.

A technique that allows to recover changes that occurred since the last backup in the event of a system crash is known as: Replication Journaling Virtualization Mirroring

Journaling

Which of the answers listed below refers to a device designed to supply (and monitor the quality of) electric power to multiple outlets? PSU MDF PDU IDF

PDU (Power Distribution Unit)

Which of the solutions listed below provides redundancy and fault tolerance by dividing tasks into smaller subtasks and distributing them across multiple systems to be executed simultaneously? Load balancing Multitasking Clustering Parallel processing

Parallel processing

Which of the following RAID levels does not offer fault tolerance? RAID 6 RAID 10 RAID 5 RAID 0 RAID 1

RAID 0 RAID 0 does not offer fault tolerance because it uses striping without any redundancy. If one disk fails, all data is lost. The other RAID levels (RAID 1, RAID 5, RAID 6, and RAID 10) offer varying degrees of fault tolerance by incorporating mirroring, parity, or a combination of both.

Which of the following terms refers to a backup strategy that relies on creating and maintaining copies of data in real-time or near real-time on a separate system? Mirroring Virtualization Journaling Replication

Replication

What type of backups are commonly used with virtual machines? Incremental backups Snapshot backups Tape backups Differential backups

Snapshot backups Snapshot backups are commonly used with virtual machines. They capture the state of a VM at a specific point in time, allowing quick restoration of the entire system, including its memory, disk, and configuration. While incremental and differential backups can be used in virtual environments, snapshot backups are particularly suited for VMs because of their ability to quickly capture the full machine's state.
