An Internet company plans to purchase a storage device to store archived service data and online transaction dat
a. SSDs are expensive and HDDs cannot meet the performance requirements of online services. Which features CANNOT solve this problem? (Select All that Apply)
The correct answers are A. SmartMigration and D. HyperClone. SmartMigration and HyperClone are features designed to manage storage and do not directly address the performance requirements of online services. SmartTier and HyperMetro are features designed to address performance requirements by tiering storage based on data access frequency and allowing for the replication of data across multiple sites.
Which statements are true about HyperMetro? (Select All that Apply)
HyperMetro allows the local and remote sites to run services at the same time, and a quorum server must be configured. Additionally, automatic switchover upon storage faults is supported. HyperClone can be configured for storage devices of different models and versions.
Which of the following is not one of the working principles of QoS?
Quality of Service (QoS) is a set of technologies used to ensure that network traffic is allocated resources according to predetermined priorities. The three main working principles of QoS are I/O Priority Scheduling, I/O Performance Assurance, and I/O Flow Control. I/O Latency Burst is not one of the working principles of QoS.
