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

Machine learning is a subfield of artificial intelligence that gives computers the ability to learn without explicitly being programmed [1]. It does this by applying an algorithm to large amounts of data in order to discover patterns and insights that can be used to inform decisions and predictions. This allows machines to learn from experience and make decisions in a way that mimics the human brain.

When an Ethernet frame is larger than the maximum transmission unit (MTU) of a link, it must be fragmented into smaller pieces, which are sent separately and reassembled at the receiver. This is known as IP packet segmentation. Fragmentation and reassembly of the IP packets can add significant latency and can cause performance issues for FCIP. In this scenario, the issue is specific to data replication, indicating that the issue is with the FCIP configuration or the replication application. The other options, B, C, and D, are unrelated to the issue.

Automated storage tiering is a feature of an intelligent storage system that allows data to be moved between tiers of storage based on usage patterns. This can provide better performance and cost savings by ensuring that data is stored in the most appropriate storage tier for its access patterns. For example, data that is frequently accessed can be stored in higher-performing storage tiers, while data that is infrequently accessed can be moved to lower-performing, lower-cost storage tiers.

This is because CNA adapters can support both FC and Ethernet traffic over a single cable2, reducing the need for separate host adapters for each protocol. The other options do not seem to be direct benefits of using FCoE protocol.

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

The backup server is the component that maintains the catalog containing details about the backups that have occurred. The catalog is a database that stores information about the backup jobs, such as the date, time, and type of backup that occurred, as well as the files that were backed up. The catalog also stores other information, such as the status of the backup jobs, as well as the type of data that was backed up. The backup server is responsible for managing the catalog and ensuring that the details stored in the catalog are accurate.

According to 1, cloud service models are categories of services that cloud providers offer to users and businesses. The three cloud service models are:

• Software as a Service (SaaS): The provider delivers software applications over the internet that users can access via web browsers or mobile apps. Examples: Gmail, Salesforce, Netflix.
• Infrastructure as a Service (IaaS): The provider offers computing resources such as servers, storage, networks and virtual machines that users can rent and manage via a web portal or an API. Examples: Amazon Web Services (AWS), Microsoft Azure, Google Cloud Platform (GCP).
• Platform as a Service (PaaS): The provider offers a web-based environment where developers can build cloud applications using a database, operating system and programming language provided by the provider. Examples: Heroku, Google App Engine, AWS Elastic Beanstalk.

Based on these definitions12, the cloud service model that provides compute, network and storage resources through self-service portal is Infrastructure as a Service (IaaS)34. This is because IaaS allows users to rent and manage computing resources via a web portal or an API without having to maintain the underlying elements2.

FC SANs components include network adapters, cables, and interconnecting devices. The interconnecting devices can be FC switches or FC directors, which are more scalable and reliable than FC hubs. The ports on these devices can be FC E_Ports, which connect two switches or directors together to form a fabric, or FC F_Ports, which connect to host or storage devices with FC N_Ports.

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.
