NEW QUESTION # 50
A company plans to deploy a new application in their environment. The new application requires 5 TB of storage space. During peak workloads, the application is expected to generate 3000 IOPS with a typical I/O size of 3 KB. The capacity of each available disk drive is 750 GB. In addition, the maximum number of IOPS a drive can perform at with a 70% utilization is 90 IOPS.
What is the minimum number of disk drives needed to meet the application's capacity and performance requirements for a RAID 0 configuration?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: B
Explanation:
* Capacity Requirement: 5 TB = 5000 GB
* Disk Capacity: 750 GB
* Number of Disks for Capacity:Capacity Disks=5000750=7 disksCapacity Disks=7505000=7 disks
* Performance Requirement: 3000 IOPS
* Disk IOPS: 90 IOPS (at 70% utilization)
* Number of Disks for Performance
:Performance Disks=300090=34 disksPerformance Disks=903000=34 disks
* Final Number of Disks: The higher of the two values is needed, which is 34 disks.

NEW QUESTION # 53
What is the purpose of data archiving?
- A. Transfers dynamic content that is actively accessed to archive storage
- B. Transfers fixed content that is no longer actively accessed to archive storage
- C. Transfers dynamic content that is no longer actively accessed to archive storage
- D. Transfers fixed content that is actively accessed to archive storage
Answer: B
Explanation:
Data archiving involves moving data that is no longer actively used to a separate storage system designed for long-term retention. The purpose of data archiving is to free up primary storage space, reduce costs, and ensure that inactive data is stored securely and can be retrieved when needed. Fixed content refers to data that does not change over time, such as historical records, logs, or finalized reports. By transferring this fixed content to archive storage, organizations can maintain the availability of valuable data without occupying high-performance primary storage resources.

NEW QUESTION # 54
What statement describes machine learning?
- A. Replicating a detailed process and then implementing it in software
- B. Developing a program to compute every possible outcome
- C. Applies an algorithm to large amounts of data for pattern discovery
- D. Organizes data efficiently so that compute systems can learn
Answer: C
Explanation:
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.

NEW QUESTION # 56
What is an advantage of performing incremental backups compared to cumulative backups for the same data?
- A. Requires more time to perform data backup
- B. Reduces restore time but requires a maximum of two copies
- C. Requires more storage capacity for backup
- D. Storage capacity needed for backups is significantly reduced
Answer: D
Explanation:
Incremental backups offer the advantage of significantly reducing the storage capacity needed for backups compared to cumulative backups. Incremental backups only capture and store the data that has changed since the last backup, which minimizes the amount of data stored. This is more efficient than cumulative backups, which capture all changes since the last full backup, leading to larger storage requirements.

NEW QUESTION # 57
What is true about scale-out NAS storage architecture?
- A. Grows file system dynamically as nodes are added to the system
- B. Scales the capacity within a single NAS storage system
- C. Provides fixed storage capacity that limits scalability
- D. Restricts scalability to the limits of the storage controllers
Answer: A
Explanation:
As previously mentioned, scale-out NAS architecture supports the dynamic expansion of the storage environment by incorporating additional nodes. Each node enhances the system's overall storage capacity and performance capabilities. This model ensures that storage can scale out efficiently to accommodate growing data volumes and changing business requirements, providing flexibility and resilience.

NEW QUESTION # 58
What occurs when a company's IT infrastructure security is breached by a passive attack?
- A. data is altered by an unauthorized user
- B. unauthorized system access is obtained
- C. availability of data is affected
- D. access to services is denied
Answer: B
Explanation:
A passive attack in IT security involves unauthorized monitoring and gaining access to data without altering it.
This type of attack is often used for data gathering and eavesdropping, where the attacker gains access to sensitive information without modifying or disrupting the system's operations.

What is an accurate statement about Challenge Handshake Authentication Protocol (CHAP) control?
- A. Enables an organization to use authentication services from an identity provider
- B. Provides strong authentication for client-server applications by using secret-key cryptography
- C. Enables initiators and targets to authenticate each other by using a shared secret code
- D. Allows a client to access protected resources from a resource server on behalf of a resource owner
Answer: C
Explanation:
Challenge Handshake Authentication Protocol (CHAP) is used to periodically verify the identity of a peer using a three-way handshake. This protocol is designed to provide more security than password-based authentication by using a shared secret code known only to the authenticating entities.

NEW QUESTION # 61
What is an accurate statement about governance?
- A. Creates the policies and enforces their adherence
- B. Ensures removal of data security vulnerabilities
- C. Determines strategy and operational rules by which companies are directed and managed
- D. Restricts access privileges to certain legitimate users to avoid IT managed resource conflicts
Answer: C
Explanation:
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.
NEW QUESTION # 62
In a software-defined networking architecture, which layer is responsible for handling data packet forwarding or dropping?
- A. Infrastructure
- B. Interface
- C. Application
- D. Control
Answer: A
Explanation:
In a software-defined networking (SDN) architecture, the infrastructure layer is responsible for data packet forwarding or dropping. This layer includes the physical network devices (such as switches and routers) and the software that controls them. It receives instructions from the control layer, which makes decisions about how traffic should be managed based on policies and network conditions. The infrastructure layer then implements these decisions, forwarding packets to their destinations or dropping them if necessary, ensuring efficient and secure data transmission across the network.

NEW QUESTION # 63 
Based on the exhibit, which type of storage does the "X" represent?
- A. Object-based
- B. File-based
- C. Block-based
- D. Unified-based
Answer: C
Explanation:
In storage systems, "block-based" storage refers to the storage of data in fixed-sized blocks. Each block is identified by a unique address and can be individually accessed and modified. Block storage is typically used in SAN (Storage Area Network) environments and is well-suited for databases and virtual machine file systems where high performance and low latency are critical. The "X" in the exhibit likely indicates a storage type that offers these characteristics, pointing towards block-based storage.References: Dell Information Storage and Management V5, Types of Storage Systems,Dell Certification Resource

NEW QUESTION # 65
Refer to the Exhibit:
What type of process, when performed on data, would produce the result shown?
- A. Deduplication
- B. Replication
- C. Migration
- D. Archive
Answer: A
Explanation:
* Deduplication is a process used to eliminate duplicate copies of repeating data.
* The exhibit shows a reduction in the number of shapes, indicating that duplicate data has been removed.
* Replication, archiving, and migration do not specifically involve the elimination of duplicates but rather involve copying, storing, or moving data.

Which option shows the correct sequence of steps to perform a data recovery operation?
- A. Option D
- B. Option C
- C. Option A
- D. Option B
