NEW QUESTION # 90
What is the lowest to highest order of I/O performance among these storage devices?
- A. SATA--> SSD--> SCM --> DRAM
- B. SSD --> SCM--> SATA--> DRAM
- C. SCM--> SSD --> DRAM--> SATA
- D. DRAM--> SCM--> SSD-> SATA
Answer: D
Explanation:
* DRAM (Dynamic Random-Access Memory) offers the highest I/O performance due to its extremely low latency and high-speed access capabilities.
* SCM (Storage Class Memory) follows DRAM, providing high performance but with slightly higher latency than DRAM.
* SSDs (Solid State Drives) come next, offering fast access times but slower than SCM and DRAM.
* SATA (Serial ATA) drives are the slowest among these options, as they typically use mechanical components (in the case of HDDs) and have lower data transfer rates compared to SSDs.

NEW QUESTION # 91
Which method automatically allocates a large capacity secondary cache using SSD and SCM?
- A. Volatile cache
- B. Non-volatile cache
- C. Cache provisioning
- D. Cache tiering
Answer: D
Explanation:
Cache tiering automatically allocates a large capacity secondary cache using Solid State Drives (SSDs) and Storage Class Memory (SCM). This method optimizes storage performance by dynamically assigning frequently accessed data to faster storage tiers, such as SSDs and SCM, while less frequently accessed data remains on slower storage tiers.

NEW QUESTION # 93
A company finance department needs 250 GB of storage for their business applications. A LUN is created with 250 GB, and RAID 1 protection. The LUN is configured to support application I/O performance.
If storage cost is $2 per GB, what is the chargeback amount to the department for application storage?
- A. $ 2000
- B. $500
- C. $1000
- D. $250
Answer: A
Explanation:
RAID 1 mirrors data, meaning it duplicates the data on two disks. Therefore, to provide 250 GB of usable storage, 500 GB of total storage is required (250 GB for the primary data and 250 GB for the mirrored copy).
At a cost of $2 per GB, the chargeback amount is calculated as
follows:Chargeback amount=500GB×$2/GB=$1000Chargeback amount=500GB×$2/GB=$1000 References:

NEW QUESTION # 94
A Fibre Channel switch has eight ports and all ports must be operational from 8 AM to 8 PM, Monday through Friday. However, a failure of Port 7 occurs in the week as follows:
Monday = 11 AM to 12 PM
Wednesday = 4 PM to 9 PM
Thursday = 4 AM to 9 AM
Friday = 2 PM to6 PM
Saturday = 9 AM to 1 PM
What is the availability of Port 7 in that week?
- A. 80%
- B. 83.3%
- C. 68.3%
- D. 75%
Answer: B
NEW QUESTION # 95
What is true about the FCIP?
- A. connects local iSCSI SANs to remote FC SANs
- B. connects local FC SANs to remote FC SANs
- C. connects local iSCSI SANs to remote iSCSI SANs
- D. connects local FC or iSCSI SANs to remote FC or iSCSI SANs
Answer: B
Explanation:
FCIP (Fibre Channel over IP) is used to extend Fibre Channel networks over IP networks. It connects local Fibre Channel SANs to remote Fibre Channel SANs, enabling long-distance connectivity and disaster recovery solutions.
References: Dell EMC ISM V5 Module 7, "Storage Network Connectivity," provides details on FCIP and its use cases.
NEW QUESTION # 96
A customer uses FCIP to connect local and remote FC SANs. The remote SAN is continuously replicated to, and used to store daily backup data. Latency over the IP WAN increases to unacceptable levels during peak replication periods.
No other data
transfer services using the WAN experience the same latency problem.
What is the likely cause of the data replication performance issue?
- A. Ethernet frame segmentation
- B. IP packet segmentation
- C. FCIP gateway FC ports set to EX_Port mode
- D. FCIP gateway FC ports set to TE_Port mode
Answer: B
Explanation:
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.
NEW QUESTION # 97
What is an advantage of implementing file-level virilization in a data center environment?
- A. Allows users the ability to only use a physical path to access files
- B. Provides dynamic distribution of files across NAS clients
- C. Provides the capability to access files from any device
- D. Provides non-disruptive file mobility across NAS devices
Answer: D
NEW QUESTION # 98
Which statement is true regarding virtual provisioning?
- A. Virtual provisioning prevents issues that arise from oversubscription
- B. Virtual provisioning enables more efficient allocation of storage to compute systems
- C. Multiple shared storage pools can be created while each pool must be allocated to a unique thin LUN
- D. Shared and Thin LUNS can be expanded rapidly with only minor disruptions
Answer: B
Explanation:
Virtual provisioning is a storage management technique that enables more efficient allocation of storage to compute systems. It allows storage administrators to create virtual storage resources that are presented to compute systems as if they were physical resources, even if the physical storage capacity does not exist.
Virtual provisioning supports various types of virtual storage, including thin LUNs and thin clones. Thin LUNs enable shared and rapid expansion with only minor disruptions. Multiple shared storage pools can be created, and each pool can be allocated to multiple thin LUNs. However, virtual provisioning does not prevent issues that arise from oversubscription; it is important to monitor and manage capacity utilization to avoid performance degradation or service disruptions. Reference: Section 2.5.1 Virtual Provisioning, page 107.

NEW QUESTION # 103
An IT organization wants to deploy four FC switches for compute and storage system connectivity. To meet performance requirements, a maximum of one active ISL and redundant ISLs for their compute to storage traffic.
Which FC SAN topology should be recommended?
- A. Single switch
- B. Multi-switch
- C. Full mesh
- D. Partial mesh
Answer: C
Explanation:
In a full mesh topology, every switch is connected to every other switch, providing multiple paths for redundancy and performance. This setup is ideal for meeting performance requirements and ensuring that there is always a path available even if one link fails, fulfilling the need for redundant ISLs.

NEW QUESTION # 105
Which standard provides lossless transport to an FCoE Ethernet network?
- A. Data Center Bridging
- B. Priority-based Flow Control
C Remote Direct Memory Access - C. Data Center Bridging Capability Exchange
Answer: B
Explanation:
Priority-based Flow Control (PFC) is a standard used in Ethernet networks, including those implementing Fibre Channel over Ethernet (FCoE), to provide lossless transport. PFC enables the Ethernet network to pause traffic classes independently, preventing packet loss during congestion and ensuring reliable data transfer without loss, which is critical for storage protocols like FCoE.

NEW QUESTION # 106
What is a primary benefit of using data replication in a data center environment?
- A. Reduces duplicate data
- B. Reduces the cost of storage
- C. Provides data archiving capability
- D. Ensures business continuity
Answer: D
Explanation:
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.

What is the MTBF of Port 5?
- A. 32 hours
- B. 40 hours
- C. 38 hours
- D. 30 hours
