EMT Practice Test

1. Question Content...

---

Question1:
The customer expects at least 2GB/s of backup throughput but only sees 1GB/s. What is causing the issue?

Question2: What type of network connection load balancing does FlashBlade use?

Question3: A customer has multiple FlashBlades and reports performance issues that occurred in the past 24 hours.
Where should the architect go to identify the issue?

Question4: A customer application requires 4.2GB/s of sustained write performance. What is the minimum number of blades to meet the performance requirement?

Question5: Which two Ethernet speeds do the External Fabric Modules support for data? (Select two.)

Question6: A customer map application is built with a containerized micro-service infrastructure that runs on Windows and accesses storage using SMB.
Each container is stateless, but every end user interaction leaves a set of small text and image files. Each directory keeps all daily transaction files. A process exists to manage file life cycle and periodically delete a directory.
The customer notices that as the customer base grows, the background deletion process backlog also grows.
Which FlashBlade technology should be used to resolve this issue?

Question7: A state agency wants to store property deed image in multi-page .tif format on a FlashBlade NFS file system.
What compression ratio should the architect utilize for sizing?

Question8: A customer has two workflows. One workflow can use either SMB 3.0 or ISCSI. The other only leverage NFS.
What should the architect recommend as a strategy?

Question9:
A customer decides to use S3 as a protocol between the Backup Server to FlashBlade. The Backup Application S3 client in multi-threaded. What is the expected maximum restore throughput?

Question10: An oil company moves geological data between their offices in Dubai and Houston for redundancy. The data is accessed via NFS mounts on a cluster of three 10GB connected Linux servers at each location.
A series of cron jobs are leveraged to replicate data from data storage pool A in Dubai to data storage B in Houston and from data storage A in Houston to data storage pool B in Dubai.
Data in storage pool A is read-write, updated by 50 cellular connected data collector running in the field, and deleted after 30 days.
Data in the storage pool B is read-only, queried by the firm's analytics team, and copied to a cloud-based archive repository every 30 days.
The total amount of data in pool A in Dubai is 1.5PB
The total amount of data in pool B in Houston is 500TB
The data is not expected to grow in the next 12 months and is compressed by the application.
Which configuration should the architect present to meet this customer needs?

Question11: The development teams at a company are shifting to a CI/CD model of development using containers and Kubernetes for orchestration.
Which Pure technology should they use?

Question12: A customer is a heavy Windows user and generally uses SMB for everything, including backups. The customer wants to refresh the storage used within their backup environment. The customer is using Commvault for the backup software.
Which protocol should the architect recommend?

Question13: How many rack units does a FlashBlade system with 39 blades consume?

Question14: What must an architect do to delete a filesystem?

Question15: A FlashBlade is designed with a properly implemented single 4x40Gb/s LAG.
During implementation, the architect is informed that the ISL on the uplink switches in broken. The customer has no budget to repair or replace it. What should the architect do?

Question16: What is the recommended number of power cables for a multi-chassis FlashBlade configuration with 4 chassis?

Question17: A customer is using an older nearline SAS scale-out storage system to store data that is a static size. The customer recently purchased several HPC appliances to use that data.
What happens to the workflow?

Question18: A company has a datacenter with a lot of electromagnetic interference. Their switches are 9m away from the FlashBlade and do NOT support speed faster than 10Gb/s.
Which cable should the architect use?

Question19: Which of the following benefits does FlashBlade SafeMode offer?

Question20: A customer is standing up a new 30x17TB FlashBlade system.
The customer's environment is as follows:
1.The upstream switches are located 50 feet away
2.The upstream switches have the required number of 100Gb/s interfaces.
3.The customer is conscious about data availability.
4.The customer requires the use of 4 LAGs
What is the minimum number of cables required?

Question21: A current FlashBlade customer has a chip design process that is not meeting their SLAs. Although the customer is using fast remove, the IOPS on their 7x17TB FlashBlade have plateaued around 700K IOPS.
What should the architect recommend adding?

Question22: A customer wants to deploy AI/ML using Pure Storage AIRI reference architecture.
Which model should the architect use to meet the requirements?

Question23: What is the maximum file size that is supported by the FlashBlade?

Question24: What is the total number of uplinks that can be utilized by the two XFMs, in any FlashBlade multi-chassis configuration?
