Dell-EMC e20-555 practice test

Question 1

A 6 F800 node Isilon cluster has one subnet with two IP pools with LACP aggregated 10GigE
interfaces from all the nodes in the Data-Zone Access Zone. The NFS-Pool with dynamic IP
Allocation schema and SMBPool with static IP Allocation schema are being used.
All the Linux clients are accessing Isilon exports using NFSv3 via the NFS_Pool. All the Windows
clients are accessing Isilon shares using SMBv3 via the SMB_Pool.
While deploying Isilon, the customer reserves the whole network subnet for Isilon. The customer is
facing performance issues with a new workload that is accessing the Isilon via Kerberized NFSv4.
What is recommended when creating a new IP pool for NFSv4 clients?
A. Dynamic IP Allocation in the System access zone
B. Dynamic IP Allocation in the Data-Zone access zone
C. Static IP Allocation in the System access zone
D. Static IP Allocation in the Data-Zone access zone

Question 2

A customer has a cluster of 16 A200 nodes. Due to recent and forecasted growth, they have decided
to
expand the cluster by an additional 24 A200 nodes.
How many neighborhoods will exist on the cluster when all nodes have joined the cluster?

• A. 1
• B. 2
• C. 4
• D. 6

Question 3

When installing nodes into a Dell EMC rack, which node type requires the use of a Titan-HD rack?

• A. H500
• B. F800
• C. A2000
• D. A200

Question 4

How are clients, L1 cache, L2 cache, and disks interconnected?

• A. Clients connect to L1 Cache and write coalescer L1 cache is connected to L2 on the local node L2 cache connects to disks on all nodes via internal network
• B. Clients connect to L2 Cache and write coalescer L1 cache connects to disks on all nodes via internal network L2 cache is connected to L1 on the local node
• C. Clients connect to L2 Cache and write coalescer L1 cache connects to disk on its local node L2 cache is connected to L1 on all nodes via internal network
• D. Clients connect to L1 Cache and write coalescer L1 cache is connected to L2 on all nodes via internal network L2 cache connects to disks on its local node

Question 5

What is a consideration when designing access zones?

• A. Authentication providers are restricted to one specific zone
• B. UID/GID ranges should not overlap for providers in the same zone
• C. Access zones cannot overlap the same directories
• D. Share names must be unique between different access zones

Question 6

The security team at a customer site has created a new requirement that in-flight replication traffic
must be encrypted end-to-end. The customer is running OneFS 8.2.1 on their cluster.
What encryption protocol versions does SyncIQ support?

• A. TLS 1.3 and OpenSSL 1.1.1
• B. IPSec 2.1 and OpenSSL 1.0.2
• C. TLS 1.2 and OpenSSL 1.0.2
• D. x.509 13.37 and OpenSSL 0.9.8

Question 7

What are attributes of SFTP?

• A. Uses FTP protocol Uses port 22 Requires client software
• B. Uses FTP protocol Uses port 990 Requires client software
• C. Does not use FTP protocol Uses port 990 Does not require client software
• D. Does not use FTP protocol Uses port 22 Requires client software

Question 8

Which balancing option is provided by SmartConnect Basic?

• A. Round-Robin
• B. Throughput
• C. CPU usage
• D. Connection count

Question 9

Your customer has an Isilon Gen 6 cluster with eight H400 nodes. During an unexpected power
outage some
of the nodes go offline simultaneously.
How many nodes need to remain up and communicating over the backend network to maintain a
quorum in
the cluster and still enable write access to the OneFS file system?

• A. 2
• B. 4
• C. 5
• D. 6

Question 10

A customer has a cluster running with a single access zone and serves multiple internal departments.
The clients access the cluster over both SMB and NFS protocols. A department user has been
assigned the task of auditing SMB activity and enforcing appropriate quotas for certain users.
How should the cluster administrator grant this access?

• A. Create a custom RBAC role
• B. Create a secondary root account credential
• C. Provide the AuditAdmin RBAC role
• D. Provide the SecurityAdmin RBAC role
