質問 # 109
An organization wants to replicate data over a public network to a cloud.
Which security control mechanism helps to secure the data during replication?
- A. Data compression
- B. LUN masking
- C. Encryption
- D. Data shredding
正解：C
解説：
Encryption is the security control mechanism that helps to secure data during replication over a public network to a cloud. By encrypting data, it ensures that even if the data is intercepted during transmission, it cannot be read or tampered with by unauthorized parties. Encryption algorithms transform the data into a secure format that can only be decrypted by authorized users with the correct decryption key, thereby protecting the data's confidentiality and integrity.References:= Dell Information Storage and Management V5 course materials
質問 # 110
What accurately describes an object-based storage device (OSD)?
- A. One object can be placed inside another object
- B. Objects exist at the same level in the address space
- C. Objects are created based on the name and location of the file

正解：B
質問 # 111
An organization is planning to adopt pre-integrated systems to deploy compute, network, storage, and management functions as a single engineered solution.
Which approach should the organization adopt?
- A. Vendor ready solutions
- B. DIY approach
- C. DCaaS solution
- D. Service based approach
正解：A
解説：
Pre-integrated systems that deploy compute, network, storage, and management functions as a single engineered solution are referred to as "Vendor ready solutions." These solutions are pre-configured and optimized by the vendor to ensure compatibility and performance, reducing the complexity and time required for deployment compared to a DIY approach or service-based approach. This is especially beneficial for organizations looking to quickly implement an integrated system with minimal customization.References:

質問 # 112
What is the functionality of the application server in a Mobile Device Management?
- A. Perform administration and management of all managed devices
- B. Authorize devices directed to the server
- C. Authenticate the device that requests access
- D. Perform administration and management of all unmanaged devices
正解：C
解説：
MDM is a control that restricts access to an organization's resources only to authorized mobile devices.
質問 # 113
What is the result of increasing the number of FC switches in a full mesh topology?
- A. Reduces available node ports for ISL connectivity
- B. Reduces number of storage and compute ports for node connectivity
- C. Reduces switch ports available bandwidth for node connectivity
- D. Reduces switch ports available for node connectivity
正解：D
解説：
In a full mesh topology, increasing the number of FC switches leads to a higher number of inter-switch links (ISLs). These ISLs consume switch ports that would otherwise be available for node connectivity, thereby reducing the total number of ports available for connecting storage and compute nodes.

質問 # 116
What is an impact of a Denial of Service (DoS) attack?
- A. Prevents legitimate users from accessing IT resources or service
- B. Compromises user accounts and data to malicious insiders
- C. Duplicates user credentials to compromise data security
- D. Hijacks privileges to compromise data security
正解：A
質問 # 117
What is a function of VM hardening?
- A. Isolate VM storage media to ensure data validity
- B. Isolate VM storage media to prevent data leaks
- C. Implement access control list across the VMs to enhance security
- D. Change the default configuration of the VM to enhance security
正解：D
解説：
VM hardening involves changing the default settings of virtual machines (VMs) to improve security. This process includes disabling unnecessary services, applying patches, and configuring security policies to protect against vulnerabilities and attacks.
References: Dell EMC ISM V5 Module 10, "Security and Virtualization," discusses the importance of VM hardening and specific practices.
質問 # 118 
Based on the exhibit, which type of storage does the "X" represent?
- A. File-based
- B. Block-based
- C. Unified-based
- D. Object-based
正解：B
解説：
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
質問 # 119
Which backup component sends metadata and tracking information about each backup to the system that maintains this information?
- A. Backup device
- B. Storage node
- C. Backup agent
- D. Backup server
正解：D
解説：
The backup server is responsible for managing the backup operations, including sending metadata and tracking information about each backup to the system that maintains this information. This centralized management ensures that backup processes are monitored, and data integrity is maintained.

質問 # 126
What is a primary benefit of using data replication in a data center environment?
- A. Provides data archiving capability
- B. Reduces the cost of storage
- C. Reduces duplicate data
- D. Ensures business continuity
正解：D
解説：
Data replication is a critical function in data center environments as it creates copies of data across different locations. This redundancy ensures that in the event of a hardware failure, natural disaster, or other disruptions, the data remains accessible from the replicated copies. Consequently, data replication is essential for maintaining business continuity, minimizing downtime, and ensuring that critical operations can continue without interruption.References: Dell Information Storage and Management V5 documents.
