What is a key benefit for deploying a remote data protection and recovery solution in a data center environment?
- A. Avoids security risks that exposes the business data
- B. Reduces required maintenance time for IT resources
- C. Reduces the cost of protecting data
- D. Maximizes application and information availability
Answer: D
Explanation:
According to 1, a remote data protection and recovery solution is a solution that enables data backup and recovery across geographically dispersed locations. It can be implemented using various technologies such as remote replication, cloud backup, and backup appliances.
One of the key benefits for deploying a remote data protection and recovery solution in a data center environment is that it maximizes application and information availability1. This means that it ensures that critical applications and data are always accessible and recoverable in case of any disaster or disruption. A remote data protection and recovery solution can also provide other benefits such as reducing costs, improving security, and simplifying management.
NEW QUESTION # 27

NEW QUESTION # 28
What is an advantage of deploying intelligent storage systems in the data center?
- A. Migrates data from a data center to the cloud at no cost
- B. Reduces the amount of data to be replicated, migrated, and backed up
- C. Reduces the complexity of managing information by creating silos of storage
- D. Enables efficient and optimized storage and management of information
Answer: D
Explanation:
Deploying intelligent storage systems in the data center enables efficient and optimized storage and management of information. These systems leverage advanced technologies like AI and machine learning to automate data management tasks, improve resource utilization, and enhance data protection. This results in better performance, lowercosts, and improved reliability compared to traditional storage systems. Intelligent storage systems can also provide insights and analytics to help organizations make better decisions regarding their data.

NEW QUESTION # 29
What is a benefit of differential backup over incremental backup?
- A. Differential backups have longer restore times than incremental backup.
- B. Incremental backup can expand to contain more data than differential backup.
- C. Differential backup can expand to contain more data than an incremental backup
- D. Incremental backups determine the backup copy used to restore the data.
Answer: C
Explanation:
Differential backups are more efficient than incremental backups because, instead of backing up only the changes made since the last backup, they back up all of the data that has changed since the last full backup.
This means that, unlike incremental backups, the size of the differential backup is not limited and can expand to contain more data than an incremental backup. Additionally, differential backups are faster to restore since they only need to read the differential backup and last full backup, rather than all of the incremental backups.

NEW QUESTION # 33
An organization wants to consume compute, network, and storage resources through self-service portal.
Which cloud service model provides this capability?
- A. Infrastructure as a Service
- B. Platform as a Service
- C. Software as a Service
- D. Data as a Service
Answer: A
Explanation:
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.
NEW QUESTION # 34
