DEA-1TT5 Associate - Information Storage and Management (Version 5.0) Questions and Answers

In your scenario, a full backup was performed on Sunday and incremental backups were performed on Monday, Tuesday and Wednesday. If files were accidentally deleted Thursday morning, you would need two backup copies to restore the files: the full backup from Sunday and the incremental backup from Wednesday. This is because the incremental backup from Wednesday would contain all the changes made since Sunday’s full backup.

Consumers have control over deployed applications and application hosting environment configurations.

Seek time, Rotational latency, and Data transfer rate are the three factors that govern the overall performance of a hard disk drive (HDD). Seek time is the time required by the read/write head to move to the correct location on the disk, rotational latency is the time required by the disk platter to rotate to bring the desired sector under the read/write head, and data transfer rate is the speed at which data can be transferred between the disk and the buffer (or cache) memory [1]. Bandwidth, RAID level, and I/O operations per second are not factors that govern HDD performance.

Organizations must store, protect, and manage their data in order to comply with the various laws and regulations governing the use and storage of data, such as GDPR and CCPA. By properly managing their data, organizations can ensure that they are compliant with these regulations and avoid potential penalties. Additionally, by storing, protecting, and managing their data, organizations can ensure that their data is secure and protected from malicious actors.

it is important for organizations to store, protect and manage their data because data is a valuable asset that can drive business growth, innovation, and competitive advantage. Data can also be subject to various risks such as loss, corruption, theft, unauthorized access, and compliance violations.

One of the reasons why it is important for organizations to store, protect and manage their data is to meet the requirements of legal and data governance regulations1. This means that organizations should comply with the laws and policies that govern how data should be collected, stored, processed, shared, and disposed of. Data governance also ensures that data quality, security, privacy, and ethics are maintained throughout the data lifecycle.

Cloud tiering is a technology that automatically moves inactive or infrequently accessed data from high-performance primary storage to lower-cost secondary storage, such as cloud-based object storage. This process is based on policies that are defined by the IT administrator. Cloud tiering is a part of the secondary storage tier, which is typically used for storing inactive or infrequently accessed data that does not require the high performance or low latency of primary storage. The primary storage tier is used for storing active or frequently accessed data that requires high performance and low latency. The application tier is used for hosting applications and services, while the policy tier is used for defining and enforcing data management policies. Reference: Section 4.4 Secondary Storage Tier, page 239.

Governance is a practice of creating and enforcing policies that guide an organization in how it should be managed and operated. This includes developing strategies, setting operational rules, and making decisions that direct how an organization should be run. It is important to note that governance is not limited to only IT-related matters, as it encompasses all aspects of the organization, from financial to personnel management.

A hypervisor is a layer of software that runs directly on top of a physical server and provides a virtualization layer. It allows multiple virtual machines (VMs) to run on the same physical hardware, sharing the underlying resources such as CPU, memory, and storage. The hypervisor isolates the VMs from each other and provides a virtual machine monitor (VMM) that manages the virtual machines' access to physical resources. The VMM is responsible for managing the VMs' creation, configuration, and removal, as well as their access to the physical resources of the host system. T

Local replication is a technique that replicates data within the same array or the same data center1. Local replication can enable operational recovery in the event of data loss by providing fast and frequent point-in-time copies of data that can be used for restore and restart operations23.

Enables operational recovery in the event of a site-level disaster is not a benefit of performing local replication. Local replication does not protect data from site-level disasters because it replicates data within the same site1. To protect data from site-level disasters, remote replication is needed to replicate data at a remote site2.

Provides disaster recovery as a service offering is not a benefit of performing local replication. Disaster recovery as a service (DRaaS) is a cloud-based service that provides backup and recovery capabilities for an organization’s data and applications4. DRaaS typically uses remote replication to store data in cloud storage locations that are geographically dispersed4.

Reduces the time to perform data backups is not a benefit of performing local replication. Data backups are different from data replication because they create secondary copies of data that are stored separately from primary copies and can be retained for longer periods5. Data backups may use local or remote replication as part of their process, but they also involve other steps such as deduplication, compression, encryption and verificatio
