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

RAID 5provides acost-effective balancebetween:

Data protection(single parity, can tolerate one disk failure).

Performance(especially read-heavy environments).

Cost(uses fewer drives than RAID 1 or 6 for the same capacity).

RAID 1 (B): Best for read-heavy workloads but doubles the storage needed (mirroring).

RAID 0 (C): No protection against disk failure.

RAID 6 (D): More protection (dual parity), but more write penalty and more disks needed.

AnF_port (Fabric port)is used on a Fibre Channel switch to connectN_ports (Node ports)on end devices like servers and storage arrays.

N_port:On the compute system (HBA).

F_port:On the switch, accepting N_port connections.

E_port:For switch-to-switch ISL (Inter-Switch Link) connections.

G_port:A generic port that can operate as either an F_port or an E_port (not the direct answer in this scenario).

5Grepresents the fifth generation of mobile networks and offers several significant advantages over 4G, 3G, and earlier generations:

Increased speed:5G delivers data speeds up to 100 times faster than 4G LTE.

Enhanced capacity:Supports more devices per square kilometer, crucial for IoT and smart cities.

Low latency:Reduces delay in data transmission, enabling real-time applications like remote surgeries or autonomous vehicles.

Increased bandwidth(Option B) is part of the overall increased capacity.

Reduced distance(Option C) is incorrect; 5G uses shorter wavelengths, meaning shorter range.

Lower cost(Option D) is not a key advantage of 5G technology itself.

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.

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.
