QUESTION 45
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?

QUESTION 46
A customer is using the FlashBlade as an image database backup/restore target. The dataset that they are backing up is 100TB. The customer has a 5-day snapshot retention policy, and an average of 50TB of data change from day to day.
Which factor will alter the physical datasize?

QUESTION 47
Which two Ethernet speeds do the External Fabric Modules support for data? (Select two.)

QUESTION 48
The customer wants to build a software QA infrastructure using modern big data tools like Spark and Kafka.
The goal is to process 50 billion events per day and provide feedback in real-time in less than 5 seconds.
The architect needs to create a FlashBlade configuration to meet the capacity and performance requirements using the following assumptions:
4 RSyslog servers accessing FlashBlade via NFS
6 servers accessing FlashBlade via S3
Capacity: 6TB + 18TB + 18TB
Each protocol will create a concurrent write and / or read throughput of 6GB/s Which configuration should the architect use to meet these requirements?

QUESTION 49
A customer wants to use FlashBlade as storage for a business critical, high-traffic SQL server. Why will this architecture fail?

QUESTION 50
A customer application requires 4.2GB/s of sustained write performance. What is the minimum number of blades to meet the performance requirement?

QUESTION 51
An HPC environment has the following:
-100 physical hosts, each with a single 10GbE NIC, and a single NFS mount point to the FlashBlade.
-A 7x52TB FlashBlade, connected to the Top-of-Rack switches via eight 40GbE connections.
What is the maximum aggregate write throughput the customer should expect from the FlashBlade?

QUESTION 52
A customer is adding snapshot policies so that some file systems can be tiered based on importance to the business.
-1 file system with high priority
-3 file systems with medium priority
-2 file systems with low priority
How many snapshot policies does the customer need to protect all of their file systems?

QUESTION 53

The customer reports that the end clients shown in the diagram are NOT completing jobs on time. Each client writes 300MB/s to the FlashBlade for 45 minutes every hour, and they run concurrently. What does the architect need to do?

QUESTION 54
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?

QUESTION 55
A customer has an application that needs to prioritize speed for untrusted applications to put large numbers of files on an NFS export. Which NFS Export options should be used?

QUESTION 56
What is the support speed of the out-of-bound management port?

QUESTION 57
A customer has hundreds of TB of data that they need to archive for 20 years. The customer will need to completely destroy the data. They will only to access the data once or twice during the 20 years. The data is very sensitive. It would be a serious security breach if anyone accessed the data during that time. The customer is considering NAS.
Why should the architect recommend another solution?

QUESTION 58
A customer has an application that stores GIS data in an S3 repo. For compliance reasons, the GIS data that existed at a previous point in time may need to be accessed.
What should the architect do?

QUESTION 59
A customer practices agile development, and they are having performance issues with builds of the most actively developed software suite as they attempt additional concurrent builds. What is causing the issue?

QUESTION 60
The customer has legacy production application that uses a hard-coded S3 access key with an encrypted hash for the secret key. The customer wants to enable development access to the production S3 bucket using the same S3 user account with a 60-day key rotation.
What should the architect do?

QUESTION 61
A customer is adding a micro-service to an existing application and needs to use the same user and S3 bucket.
The current secret key is unknown.
What should the customer do to resolve this issue?

QUESTION 62

The customer is deploying FlashBlade on a ship with no immediate access to replacement part inventory. The customer needs at least 100TB of usable capacity at any time. The customer assumes worst case scenario in which FlashBlade can lose two blades between visting the next port where replacement can be shipped.
What is the recommend FlashBlade configuration?

QUESTION 63
A customer is architecting a new distributed application in their datacenter.
Which network device should be used for optimal network performance?

QUESTION 64
A customer has a 7x52TB system and reports poor workload performance.
The customer provides the following information:
1.The customer has 4 host connecting using NFS.
2.The environment is running VMware with 300 VMs.
3.The FlashBlade is connected to the customer network using 4x40Gb/s links What is causing this issue?

QUESTION 65

What are Port 31/32 on the XFMs reserved for?

QUESTION 66


The customer provides the network diagram shown. The customer wants to use RBAC and SMB on the FlashBlade. The customer does NOT use encryption for identity-related traffic.
Which ports must be opened for this to work?

QUESTION 67
