Question 26 of 30
26. Question
Mr. Brown is troubleshooting a performance issue in an Isilon cluster used for a high-frequency trading application. He suspects that network latency is a problem. Which metric should he primarily focus on?
Correct
In a high-frequency trading application, latency is a critical metric because it directly impacts the speed at which transactions are processed. Focusing on network latency will help identify any delays in data transfer within the Isilon cluster. CPU utilization and disk I/O operations are important but not as directly related to network performance issues in this context.

Question 27 of 30
27. Question
Mr. Thompson, an IT administrator at a large corporation, is tasked with migrating terabytes of data from an aging storage system to a new Isilon cluster. The deadline is tight, and there’s a risk of data corruption during the migration process. What should Mr. Thompson do to ensure a successful migration?
Correct
In this scenario, option B is the correct answer. Data migration is a critical process, especially when dealing with large volumes of data. Thorough testing on a small subset of data allows for the identification of any potential issues or risks before migrating the entire dataset. Skipping the testing phase (option C) could lead to data corruption or loss, violating the principle of data integrity. Delegating the task to junior staff without proper oversight (option D) increases the risk of errors and compromises the success of the migration. Performing the migration during peak hours (option A) might disrupt regular operations and impact the overall performance of the system, which contradicts optimization techniques.

Question 28 of 30
28. Question
Ms. Rodriguez, a support engineer, receives an alert indicating a critical error on an Isilon cluster. Upon investigation, she discovers that a node has failed, and the cluster is operating in a degraded state. What should Ms. Rodriguez prioritize to restore the cluster’s functionality?
Correct
When encountering a critical error, it’s crucial to conduct a thorough analysis to identify the root cause of the issue. Simply replacing the failed node without understanding why it failed may not prevent future occurrences and could lead to further downtime. Ignoring the alert (option C) or restarting the entire cluster (option B) without proper investigation can exacerbate the problem and compromise data integrity. Prioritizing the assessment of the root cause aligns with the support and maintenance principles, emphasizing proactive troubleshooting and resolution.

Question 29 of 30
29. Question
Dr. Lee, a storage architect, is exploring object storage solutions to address the scalability and accessibility requirements of unstructured data. She needs to evaluate the suitability of Isilon’s Object Storage capabilities for storing large volumes of files and objects. What features of Isilon Object Storage should Dr. Lee consider in her evaluation?
Correct
Option C highlights a key feature of Isilon Object Storage that Dr. Lee should consider: scalability to petabytes of storage capacity without compromising performance. Isilon’s architecture allows for seamless scaling of storage resources to accommodate growing data volumes while maintaining optimal performance. This scalability is essential for handling large repositories of unstructured data efficiently. Option A is incorrect because Isilon Object Storage focuses on object-based storage rather than block-level storage with low-latency access. While Isilon can integrate with cloud-based storage services (option B), this isn’t specific to its Object Storage capabilities. Option D’s mention of limited metadata indexing capabilities is inaccurate; Isilon provides robust metadata indexing for efficient data retrieval in Object Storage environments.

Question 30 of 30
30. Question
Mr. Patel, a system architect, is tasked with expanding an existing Isilon cluster to accommodate growing storage demands. He needs to devise an implementation strategy that minimizes disruption to ongoing operations. What approach should Mr. Patel take to ensure a seamless cluster expansion?
Correct
Gradually adding new nodes to the cluster allows for a controlled expansion without disrupting ongoing operations. By redistributing data across the cluster as new nodes are added, Mr. Patel can maintain optimal performance and avoid overloading specific nodes. Shutting down the entire cluster (option B) would result in significant downtime and conflicts with data accessibility, violating the principle of continuous availability. Ignoring performance metrics (option C) disregards the importance of optimizing cluster performance during expansion. Conducting the expansion during peak usage hours (option D) risks disrupting regular operations and should be avoided to minimize user impact. This strategy aligns with best practices for implementation and scalability planning.
