質問 2：
A customer asks an architect to help troubleshoot low throughput in their high-performance compute (HPC) environment. All 70 HPC nodes have a single 10Gb connection to a 96 port 10Gb switch. The FlashBlade is connected to their dedicated HPC switch with 8x10Gb connections. The HPC application is using a single shared S3 bucket for the data being processed.
Which change is needed to increase throughput?
A. Add more uplinks to the HPC switch. ***
B. Add more IPs to the existing VLAN
C. Add more nodes to the HPC cluster
D. Add more VLANS to FlashBlade.
正解：A
質問 3：
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?
A. Ports 53 and 2049 on Firewalls A and B
Ports 53 and 389 on Firewall C
B. Ports 123, 445, and 636 on Firewalls A and B
Port 445 on Firewall B
C. Port 123 on Firewalls A and C
Ports 445 and 636 on Firewall B
D. Ports 53, 389, and 445 on Firewalls A and C
Ports 53 and 445 on Firewall B ***

C. Go to Settings/Users
D. Go to Storage/File Systems/Details
正解：B
質問 6：
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?
A. Use FlashBlade for both environments
B. Use block storage for both environments
C. Use block storage for NFS and FlashBlade for ISCSI
D. Use block storage for ISCSI and FlashBlade for NFS. ***
正解：D
質問 7：
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?
A. Increase the number of DataVIPs available to the clients.
B. Stagger the job start times between the clients. ***
C. Increase bandwidth between Switch A and the Router.
D. Add additional mount point on each client.
