D-ISM-FN-01 EMC Dell Information Storage and Management Foundations v2 Exam Free Practice Exam Questions (2025 Updated)

Capacity planning reports in storage environments focus on:

Utilization trendsof storage systems (e.g., used vs. available space)

File system usage(volumes, file systems)

Ports (SAN/NAS connections)

This enables proactive capacity management and ensures enough resources are available to meet future demands.

Rapid elasticity is a cloud computing characteristic that allows resources to be scaled up or down quickly and automatically, depending on demand. In the scenario of a sudden traffic surge, rapid elasticity enables the infrastructure to handle increased loads without manual intervention.

Measured service:Refers to monitoring and billing based on resource usage.

On-demand self-service:Allows users to provision resources as needed.

Resource pooling:Involves sharing resources among multiple users.

The exhibit shows a Fibre Channel (FC) switch connected to another FC switch. The port "X" is used for inter-switch link (ISL) connectivity, which is characteristic of anE_port (Expansion Port).

F_port (Fabric port):Connects an N_port (host or storage device) to a switch.

N_port (Node port):End device port in FC networks (like HBA in hosts or storage).

NL_port (Node Loop port):Used for Arbitrated Loop topologies.

E_port:Connects two FC switches together for ISL, which is exactly what's shown in the exhibit.

Remote data protection and recovery solutions, like replication and cloud-based backup, are primarily designed to ensuremaximum application and information availability. They protect data in the event of:

Local failures(disk, server, or site outages)

Natural disasters(floods, fires)

Ransomware attacks

By having off-site copies and failover options, businesses maintain continuous access to critical data.

OSD gateways provide access to object storage systems through APIs. The most common interfaces are:

REST (Representational State Transfer): A stateless protocol using standard HTTP methods, widely used for web services.

SOAP (Simple Object Access Protocol): A protocol for exchanging structured information in web services, using XML.

These APIs allow applications to interact with object storage systems over HTTP/HTTPS protocols.

SSH and SMB: SSH is for secure shell access; SMB is for file sharing, not typically used for object storage.

HTTP and HTTPS: These are transport protocols; while used by REST and SOAP, they are not interfaces themselves.

NFS and CIFS: File-based interfaces, not used for object storage.

In Ethernet networking, VLANs (Virtual Local Area Networks) are identified using a 12-bit VLAN ID field in the IEEE 802.1Q standard. Since 12 bits can represent 2¹² = 4096 unique values, the maximum number of VLANs that can be supported is 4096.

1024 and 2048: These values are less than the maximum and represent subsets of possible VLANs.

8192: This exceeds the 12-bit limit and is not supported by the standard.

Full Detailed Explanation with Step by Step Solutions:

A standardFibre Channel (FC) frameconsists of several fields in a specific order. The typical sequence for an FC data frame is:

1️⃣Frame header:Contains control and addressing information.

2️⃣Data field:Carries the actual payload (up to 2112 bytes).

3️⃣CRC (Cyclic Redundancy Check):Ensures data integrity of the frame.

The diagram in the exhibit shows exactly this ordering:

SOF (Start of Frame)– marks the beginning of the frame.

1 (Frame header)– the control and addressing info.

2 (Data field)– the main data payload.

3 (CRC)– for error checking.

EOF (End of Frame)– marks the end of the frame.

To implement anFC-NVMe SAN(NVMe over Fibre Channel), you need:

NVMe storage systemsthat expose NVMe namespaces.

FC-NVMe capable switchesthat support the new NVMe protocol over Fibre Channel.

Servers with NVMe HBAs(already mentioned in the question).

Option B:Ethernet networks are for NVMe-oF over TCP/RoCE, not FC-NVMe.

Option E:These drivers are for TCP/RoCE, not FC transports.

Thefifth stageof penetration testing is known aspost-exploitationoranalysis of the compromised environment. It involves:

Checking the compromised system/networkto determine the scope of access.

Identifying potential for further exploitation.

Gathering information about the environment.

Option Arelates to the risk assessment phase.

Option Bis typically done in post-exploitation but isn’t the main step.

Option D(collecting evidence) is more related to reporting/documentation at the end.

Inwrite-through caching, data is written simultaneously to both the cache and the underlying disk. This ensures data integrity because the write is not acknowledged until it’s safely written to the disk.

Write-backcaching offers reduced latency but increases risk of data loss if cache is lost.

Write-throughtrades speed for security, offeringenhanced data securityand reducing the risk of data loss during power failures.

Configuration Management is the process that ensures all configuration items (CIs) are identified, tracked, and maintained throughout their lifecycle. It maintains a Configuration Management Database (CMDB) that records the relationships and configurations of various components in the IT environment.

Astorage nodeis a component in a backup architecture that handles the actualdata movementduring the backup process:

Itorganizesthe backup data stream.

Itwritesthe data to the backup target (disk, tape, or cloud).

It does not manage policies or schedules (that’s the role of the backup server or management console).

Option A:Monitoring is done by the backup server or management tools.

Option C:Backup management (scheduling, policies) is also handled by the backup server.

Option D:Deduplication may be part of the process but is not theprimary roleof a storage node.

Astub fileis a small placeholder file that remains on primary storage after data has been archived or moved to secondary storage.

Itcontains a pointer or addressof the archived data’s location.

When accessed, the data is transparently retrieved from the archive.

Address of the source fileand other options do not accurately describe a stub file’s purpose.

To calculate the MTBF, we need to determine the total operational time and the number of failures.

Total operational time (Monday to Friday):5 days × 24 hours = 120 hours

Number of failures:3 (Tuesday, Thursday, Friday)

MTBF = Total operational time / Number of failures

MTBF = 120 hours / 3 = 40 hours

Big Data's"variety"refers to the challenge of integrating different data types (structured, semi-structured, unstructured) from various sources.

The key challenge is tocombine and manage this data cost-effectively, ensuring analytics systems can process it seamlessly.

Generating real-time datais about velocity, not variety.

Storing data over yearsis about volume.

Reducing volumeis more about data management, not variety.

RAID 1isdisk mirroring. It writes identical copies of data to two disks simultaneously, providing redundancy.

Minimum of 2 disks (no parity, no striping).

Excellent read performance, write performance equivalent to a single disk.

Providesfault tolerancebecause data is duplicated.

FCIP (Fibre Channel over IP)is used totunnel Fibre Channel traffic over IP networks. Its primary use case:

Connecting local FC SANs to remote FC SANsfor disaster recovery and remote data replication.

Itencapsulates FC framesinto IP packets, transporting them over existing IP infrastructure.

Option B/C/D:iSCSI is not directly involved in FCIP’s primary function.
