FTP (File Transfer Protocol): This is a standard protocol used to transfer files between computers over a network.SFTP (Secure File Transfer Protocol): This is an extension of the FTP protocol that provides secure file transfer using SSH (Secure Shell) encryption.QUESTION 22What is the minimum RPO that can be configured on a Dell Unity XT block-asynchronous replication session?  60 minutes  1 minute  5 minutes  20 minutes Recovery Point ObjectiveWhen you set up an asynchronous replication session, you can configureautomatic synchronization based on the RPO. You can specify an RPO from a minimum of 5 minutes up to a maximum of 1440 minutes (24 htours).QUESTION 23What is a characteristic of tenant traffic on a Dell EMC Unity array?  Separated by the associated VLANs at the Linux Kernel layer  Separated by the associated subnet providing data separation with increasing security at the network layer  Separated by one associated VLAN providing data separation with increasing security at the Linux Kernel layer  Separated by the associated subnet at the Linux Kernel layer QUESTION 24A customer site has four NAS servers participating in MetroSync replication. Which Dell EMC Unity feature could reduce failover times?  QoS Failover Policy  Cabinet Failover  SRDF Metro  Consistency Groups QUESTION 25A customer has a data center with applications running on 16 volumes that are presented from a Dell Unity XT system. They want to design a DR site within metro distance with zero RPO using storage-based replication.According to Dell best practices, which design approach minimizes the impact on storage performance?  Use multiple ports per controller for replication.  Include a Flash tier in a hybrid pool where synchronous replication is active.  Use Thick volumes within the replication group.  Create the synchronous replication session before filling the source storage object with data. * Dell Unity XT and DR Design:* For disaster recovery (DR) within a metro distance and zero Recovery Point Objective (RPO), synchronous replication is the preferred method.* Synchronous replication ensures that data is written to both the source and target volumes simultaneously, which requires high performance to minimize latency.* Best Practices for Minimizing Impact on Performance:* Multiple Ports per Controller: While this can improve throughput, it does not directly minimize the latency impact of synchronous replication.* Flash Tier in Hybrid Pool: Including a flash tier in a hybrid pool enhances performance significantly because flash drives offer lower latency and higher IOPS compared to traditional spinning disks. This is critical for synchronous replication scenarios where performance impact needs to be minimized.* Thick Volumes: Using thick volumes can provide consistent performance, but they do not inherently minimize the impact of synchronous replication.* Synchronous Replication Session: Creating the replication session before filling the source storage object with data is a procedural step and does not address performance during active replication.* Dell Midrange Storage References:* Dell Unity XT best practices emphasize the use of flash tiers in hybrid pools to boost performance for demanding operations, including synchronous replication.* Resources from Dell Technologies’ documentation on storage-based replication and performance optimization provide detailed insights.References:* Dell Unity XT Best Practices* Dell Community on Midrange Storage* Dell Storage Product InformationQUESTION 26Which two parameters avoid bottlenecks and improve performance when sizing Dell Unity XT storage solutions? (select 2)  Workload Types  Port Utilization  Network Latency  Port load balancing  Network Bandwidth QUESTION 27Which NVMe SCM drives are supported by Dell PowerStore?  800 GB and 1.6 TB  600 GB and 1.2 TB  375 GB and 750 GB  400 GB and 1 TB QUESTION 28Which features were introduced in SCOS 7.3?  Distributed Sparing and Live Volume ALUA  Data-in-Place upgrade for SC4020 and 4K HDD support  Unisphere for SC and Live Volume Auto-failover  CloudlQ support and Cross Platform Replication QUESTION 29Drag and Drop QuestionMatch each Dell EMC Unity feature with its destination. QUESTION 30Which block resources are supported with Dell EMC Unity asynchronous replication?  Consistency Groups and file systems  VMFS and NFS datastores  LUNs and file systems  LUNs and VMFS datastores Reference: https://cdn2.hubspot.net/hubfs/1885982/dell-emc-unity-unisphere- overview.pdf?t=1543339206682QUESTION 31You are designing a two-tiered Dell EMC SC Series solution that will be optimized for performance. You gather the necessary data from Live Optics and find that the read/write ratio is80:20.What approach is recommended?  Size Tier 1 for 100% of the adjusted IOPS  Use distributed adjusted IOPS for all tiers  Use distributed adjusted IOPS for Tiers 1 and 2 only  Size Tier 2 for 100% of the adjusted IOPS “The engineer should design a system to handle all, or nearly all, IOPS in one particular tier”QUESTION 32What is a benefit of using a performance assessment tool?  Retrieves workload metrics from all storage systems  Provides performance statistics in a structured postgres database  Retrieves the performance archives using the Unity Data Collection  Provides automated performance statistics in chart and table format A performance assessment tool is used to evaluate the performance of storage systems and provide statistics that can be used to identify and troubleshoot performance issues. One of the benefits of using a performance assessment tool is that it provides automated performance statistics in chart and table format, making it easy to understand performance metrics and identify any potential issues. This allows the user to quickly identify and address any bottlenecks in the system, and make adjustments to improve performance.QUESTION 33Which network option should be configured to provide the best iSCSi performance on a Dell Unity XT array?  Jumbo frames  iSCSI offload  Disable flow control  Single VLAN for all traffic QUESTION 34What non-Dell product reports can be generated using My Work?  NetApp and HDS  HP EVA and IBM SVC  HDS and 3PAR  3PAR and IBM XIV QUESTION 35What tools can be used to migrate block data from a legacy VNX array to a new Dell Unity XT array?  SANCopy and PowerPath Migration Enabler  EMCopy and SANCopy  PowerPath Migration Enabler and Rsync  Rsync and EMCopy  Loading … Best D-MSS-DS-23 Exam Preparation Material with New Dumps Questions https://www.vceprep.com/D-MSS-DS-23-latest-vce-prep.html --------------------------------------------------- Images: https://certify.vceprep.com/wp-content/plugins/watu/loading.gif https://certify.vceprep.com/wp-content/plugins/watu/loading.gif --------------------------------------------------- --------------------------------------------------- Post date: 2025-03-02 12:25:55 Post date GMT: 2025-03-02 12:25:55 Post modified date: 2025-03-02 12:25:55 Post modified date GMT: 2025-03-02 12:25:55
