問題 #28
For a PowerStore 3200T running Block Workloads, which two options does Sizer take into consideration to equate the performance for each workload? (Select 2)

A. Storage Performance Saturation
B. Response Time
C. Frontend Performance Saturation
D. Throughput

答案：B,D

解題說明：
For a PowerStore 3200T running block workloads, the Sizer tool takes into consideration several factors to equate the performance for each workload. The two main options are:
Throughput: This refers to the amount of data that can be processed by the system in a given period. It is a critical measure of the storage system's capability to handle large volumes of data efficiently.
Response Time: This metric measures the time taken to complete an I/O operation from the moment it is initiated. It is essential for assessing the performance of latency-sensitive applications.
These parameters help ensure that the storage solution is designed to meet the performance requirements of the workload, balancing between high throughput and low response times.

問題 #29
What is done during the preconfigure step of a PowerStore block import migration?

A. Source system is added to the PowerStore.
B. Import schedule is set.
C. Destination volume is created.
D. Network connectivity is set up.

答案：D

解題說明：
During the preconfigure step of a PowerStore block import migration, network connectivity is set up. This step is crucial for ensuring that the source system can communicate with the PowerStore system, which is necessary for a successful data transfer during the migration process. Here are the detailed steps involved in this phase:
* Assess Network Requirements:Evaluate the existing network infrastructure to ensure it meets the requirements for a PowerStore migration. This includes checking the bandwidth, latency, and network topology.
* Configure Network Settings:Set up the network settings on both the source and destination systems.
This involves configuring IP addresses, subnet masks, gateways, and any other network parameters required for connectivity.
* Verify Connectivity:Use network diagnostic tools to verify that the source system can communicate with the PowerStore system. This might involve ping tests, traceroutes, and other connectivity checks.
* Secure the Network:Implement necessary security measures to protect the data during migration. This can include setting up firewalls, VPNs, or other security protocols to ensure data integrity and confidentiality.
* Establish Data Paths:Create and configure data paths between the source system and the PowerStore system. This ensures that data can be transferred efficiently and without interruption during the migration process.
* Test Network Performance:Conduct performance tests to ensure that the network can handle the data transfer load. This helps identify and mitigate any potential bottlenecks that could affect the migration.

By ensuring that network connectivity is properly set up, the preconfigure step lays the foundation for a smooth and successful migration of block data to the PowerStore system.

問題 #30
A Dell EMC Unity storage administrator has 10 hosts. One of the hosts experiences occasional, huge IO bursts.
What is a best practice for avoiding performance issues during these burst periods?

A. Enable Quality of Service (QoS) then configure burst settings
B. Quality of Service (QoS) is enabled by default, so one only needs to configure burst settings
C. Enable Quality of Service (QoS) then limit I/O for the entire FC port
D. Enabling Quality of Service (QoS) will limit the burst problem

答案：A

問題 #31
AN application owner needs 10 volumes for their application to be created, and they must have snapshots...
Which feature in Dell PowerStore should be used to enable this requirement?

A. Data Groups
B. Snapshot Groups
C. Volume Groups
D. Consistency Groups

答案：D

問題 #32
What is a Dell Unity XT best practice to provide the highest network availability for NAS?

A. Combine LACP and Fail-Safe Networking.
B. Utilize multi-pathing software such as PowerPath.
C. Configure LACP with multiple active links.
D. Configure Fail-Safe Networking with a primary link and a standby link.

答案：C

解題說明：
Configuring Link Aggregation Control Protocol (LACP) with multiple active links is a Dell Unity XT best practice to provide the highest network availability for NAS. LACP enables the bundlingof several physical Ethernet links to form a single logical link, thus providing increased bandwidth and redundancy in case of link failures.
