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

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.

Routers are networking devices that determine the optimal path for data packets to travel across networks. They primarily operate at Layer 3 of the OSI model, known as the Network Layer. This layer is responsible for logical addressing and routing, enabling data to move between different networks.

Layer 2 (Data Link Layer):Handles physical addressing and is the primary domain of switches.

Layer 3 (Network Layer):Manages logical addressing (IP addresses) and routing; the main operational layer for routers.

Layer 4 (Transport Layer):Ensures reliable data transfer but is not the primary layer for routers.

Layer 7 (Application Layer):Interfaces with end-user applications; not relevant to routing functions.

The primary purpose of a data backup solution is tomaintain business continuityby ensuring data can be restored in case of accidental deletion, hardware failure, or data corruption.

Not to reduce storage costs:Archiving and tiering handle that.

Not to improve application performance:Backup processes typically don't enhance live performance.

Not to reduce archive usage:Backup and archive have different use cases.

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.

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.

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.

AnIDPS (Intrusion Detection and Prevention System)monitors network traffic and system activities for signs of malicious activity and policy violations. It canidentify and blocksecurity threats in real-time.

Antivirus software:Focuses on detecting/removing malware, not broader vulnerabilities.

Password encryption:Secures credentials but does not identify vulnerabilities.

IAM:Manages access but does not detect attacks.

WWN zoninguses theWorld Wide Names(unique identifiers) of devices (HBAs and targets) to define zone membership.

Offers flexibility: devices can be moved to different ports without reconfiguring zoning.

Common in modern SAN environments.

Port zoninguses physical port numbers for zone membership.

Mixed zoningcombines port and WWN methods.

No zoningwould not segment traffic.

Dell RecoverPoint is a continuous data protection (CDP) solution that uses journaling to provideany point-in-time recoveryof data. It continuously captures and replicates data changes, storing them in a journal to enable precise recovery to any required point in the past.

Dell SRDF (Symmetrix Remote Data Facility):Provides synchronous/asynchronous replication, not CDP.

Dell TimeFinder SnapVX:Creates point-in-time snapshots but doesn’t offer continuous journaling.

Dell Cloud Tier:Used for archiving older data to the cloud.

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.

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.

RAID 6 uses dual parity to provide fault tolerance, which requires additional calculations during write operations. This introduces a write penalty, as the system must compute and write two sets of parity data for each write operation, leading to slower write performance compared to other RAID levels.

Insufficient storage on the RAID controller:Would affect storage capacity, not write performance.

High read I/O load on the array:Impacts read performance, not write performance.

Increased network latency:Affects data transfer times but not the internal write operations of the RAID array.

Write penalty associated with dual parity calculations:The most likely cause of slow write performance in RAID 6.

Intelligent storage systems incorporate advanced features like automated tiering, deduplication, and compression. These features enable efficient storage utilization and optimized management by automating data placement and reducing manual intervention.

Option A: While intelligent systems may facilitate cloud integration, they do not guarantee cost-free migration.

Option B: Data reduction features help, but the primary advantage is broader efficiency and optimization.

Option C: Creating silos increases complexity; intelligent systems aim to unify and simplify storage management.

Monitoringis the ongoing process of observing and tracking the performance and availability of IT infrastructure, including:

Storage devices

File systems

Ports and connectivity

It helps ensure service levels are met and detect potential issues.

Reporting: Summarizes data (often based on monitoring data).

Alerting: Notifies of specific events or thresholds (also uses monitoring data).

Infrastructure discovery: Detects and inventories devices.

TheTransport layer (Layer 4)of the OSI model ensures reliable data transfer between systems by providing:

End-to-end connections– manages communication sessions

Sequencing– orders data packets

Integrity– error detection and correction

Session (Layer 5): Manages sessions and controls dialogues between systems.

Data Link (Layer 2): Deals with local network frame delivery.

Presentation (Layer 6): Translates data formats (like encryption, compression).
