D-ISM-FN-01 Practice Exam Questions with Answers Dell Information Storage and Management Foundations v2 Exam Certification

GRC stands for Governance, Risk, and Compliance. It's a comprehensive framework that helps organizations align their IT operations with business objectives, manage risks effectively, and ensure compliance with internal and external regulations.

GDPR: A specific regulation focusing on data protection and privacy in the EU.

COBIT: A framework for IT governance and management, but not as comprehensive in risk and compliance aspects.

ITIL: Focuses on IT service management, not directly on governance or compliance.

FCIP (Fibre Channel over IP) is a protocol used to connect Fibre Channel SANs across geographically dispersed locations over IP networks. It does this byencapsulating Fibre Channel frames into IP packets(Layer 3). This allows FC SAN traffic to be transmitted across IP-based WANs.

Ethernet networks(Layer 2) are not involved in the FCIP encapsulation process directly because FCIP uses IP packets.

Splitting LAN/SAN datais not the method used; FCIP encapsulatesall FC frames.

Separating LAN and SAN dataalso does not describe the tunneling function.

Anincidentis anunplanned disruptionof a service or a reduction in its quality, often with anunknown root cause.

Incidents require immediate action to restore service.

Example: SAN switch port down, unexpected storage latency.

Support requestsare typically service requests, not incidents.

Impact actionsare more about changes, not incidents.

Events preventing correctionsmight be problems, not incidents.

Defense-in-depthis a security strategy thatlayers multiple security controlsthroughout the IT environment to protect data and infrastructure.

Firewalls (network layer)

VPN (secure remote access)

Malware protection (endpoint and gateway)

Encryption (data in transit and at rest)

This approach reduces reliance on a single security measure and strengthens overall protection.

Zero trust:Focuses on continuously validating trust.

DMZ:Network architecture, not a full security approach.

Perimeter security:Limited to the outer edge of the network.

Rebuilding a RAID 5 array after a disk failure depends on:

Capacity of the failed disk (C)– More data means longer rebuild time.

Write performance of the remaining disks (B)– Rebuild involves recalculating parity and writing data to the replacement disk, which stresses the surviving disks.

Network bandwidth (A)is only relevant for accessing the array, not for internal rebuild operations.

Cache capacity (D)helps performance in some scenarios, but the direct factors are disk size and performance.

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

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:

1??Frame header:Contains control and addressing information.

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

3??CRC (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.

Infrastructure as a Service (IaaS) is a cloud computing model that provides virtualized computing resources over the internet. It offers fundamental infrastructure services such as compute, storage, and networking, which users can provision and manage through a self-service portal. This model allows organizations to scale resources as needed and pay only for what they use.

Native NVMeis a protocol designed for direct-attached storage (DAS) environments. It allows a host to communicate with NVM storage devices (like NVMe SSDs) within the same server.

Limitation:Native NVMedoes notsupport external NVMe storage connectivity beyond the server.

To connect to external shared NVMe storage, protocols likeNVMe over Fabrics (NVMe-oF)are used.

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.

Data deduplication is a technique that eliminates redundant copies of data, storing only unique instances. When multiple copies of the same data are found, deduplication replaces them with references to a single stored copy, significantly reducing storage requirements.

Data replication:Involves copying data to another location for redundancy, not reducing storage size.

Data encryption:Secures data but doesn't affect storage size.

Data compression:Reduces data size by encoding information more efficiently but doesn't eliminate duplicates.

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.

VM cloningallows administrators to createexact copiesof a virtual machine quickly.

Saves time compared to manually configuring new VMs.

Useful for testing, development, and scaling environments.

Each clone can be independently modified after creation.

Same IP addressis typically not the case (clones get unique addresses).

Snapshotsprovide rollback points, not full VM clones.

Performancedoes not improve because of cloning itself.
