IBM Assessment: Storage Technical V1 Practice Exam 2025: Latest Questions

An application team wants to reduce latency and improve IOPS for a database workload on shared storage. Which change is MOST directly related to improving performance by reducing the amount of data written to disk?

A customer is choosing between block and file storage for a virtualization cluster. They require shared datastores presented to hypervisors with low overhead and consistent latency. Which storage access type is MOST appropriate?

A storage administrator needs to explain why multipathing software is recommended for host connections to shared storage. What is the PRIMARY benefit?

A customer wants an immutable copy of backup data to help protect against ransomware. Which approach BEST meets this requirement?

A customer wants to consolidate several small SAN arrays and simplify management while improving efficiency. Which IBM technology is MOST associated with virtualization of heterogeneous storage behind a single management layer?

After presenting new LUNs to a Linux host over Fibre Channel, the host does not show the new disks. The SAN team confirms zoning and masking are correct. What is the MOST appropriate next step on the host?

A storage array shows high read latency during peak hours. Performance graphs show cache hit ratio is low and backend disks are saturated. Which action is MOST likely to improve read performance for hot data without changing the application?

A customer needs to replicate storage volumes to a remote site with minimal data loss. The network latency between sites is significant, and the business can tolerate a small recovery point objective (RPO) but not zero. Which replication approach is MOST appropriate?

A host intermittently loses access to a SAN LUN and logs show frequent path failovers. The storage array ports are healthy. Which investigation is MOST likely to identify the root cause in the SAN fabric?

A customer plans to deploy a highly available block storage environment using two independent fabrics for redundancy. They want to avoid a single point of failure between hosts, switches, and storage. Which configuration BEST aligns with SAN best practices?

A storage engineer is explaining why a workload with many small random reads performs better on SSD-backed storage than on HDD-backed storage. Which fundamental characteristic most directly explains the difference?

An organization wants a simple way to reduce the impact of a single storage controller failure without designing a complex multi-site solution. Which approach best meets this requirement?

A team is selecting an IBM storage platform feature to improve usable capacity without changing application behavior. Which feature most directly addresses this goal?

A customer wants to consolidate block storage for VMware and physical hosts while simplifying management across multiple midrange arrays. Which IBM capability is most aligned with centralized, policy-based management for heterogeneous IBM storage environments?

A storage administrator is configuring Fibre Channel zoning for a new IBM storage deployment. Which zoning practice is generally recommended to improve security and reduce unintended access?

After presenting new LUNs to a Linux host, the host does not see the devices even though the storage array shows the mapping is correct. Multipath is installed. Which action is the most appropriate first step on the host?

A customer plans to use snapshots for fast recovery from logical corruption while keeping application performance predictable. Which best practice most directly helps maintain snapshot reliability and performance over time?

A storage team wants to improve resilience against ransomware for NAS data while still enabling user self-service restores of recently deleted files. Which combination best aligns with this requirement?

A customer uses VMware with multiple ESXi hosts connected via Fibre Channel to an IBM block array. During a path failure test, some datastores become temporarily inaccessible on a subset of hosts. Which design issue is the most likely cause?

A storage admin notices an IBM block storage system is experiencing intermittent high latency during peak hours. Array metrics show backend disks are not saturated, but write response times spike when a background task runs. Which action is most appropriate to reduce impact while preserving data services?

A customer is choosing between NVMe SSD and nearline SAS HDD tiers for a new storage system. Their primary requirement is to minimize latency for a high-IOPS database workload. Which media choice best aligns with this requirement?

A storage administrator wants to enable host multipathing to improve availability for a SAN-attached server. What is the primary benefit of configuring multiple active paths between the host and storage?

A customer wants to modernize file storage for multiple departments. Requirements: SMB and NFS access, simple management, and integration with existing Ethernet networks. Which IBM storage approach best matches these needs?

A new SAN-attached host cannot see any LUNs after zoning changes. The storage team confirms the LUN is mapped to the correct host object on the array. Which additional configuration item is most commonly missing on the SAN fabric side?

A customer reports intermittent application timeouts on a virtualized cluster using shared storage. Latency spikes occur at the same time each day, but overall throughput is not unusually high. Which troubleshooting approach is most appropriate to identify the root cause?
