Question 1

The :''nfs2'' file system has been experiencing delays that have been impacting the entire Dell EMC Isilon cluster. Neither Snapshots nor SyncIQ is configured for these directories. Use the ''Launch Simulator'' button to verify the SSD strategy. Note: It is necessary to 'close' (x) the simulator window to answer the question.

Based on your findings, which operation should be performed to address the delays?



Answer : D

Question 2

Case Study 1

A company has several independent business units that operate globally. The company has consolidated its IT infrastructure services and operations. Common infrastructural services which include IPAM, DNS, NTP, DHCP, and SMTP have been consolidated. The company has complimented its infrastructure development by investing in Dell EMC Isilon clusters to host its user's home and group directories and for compliance archival purposes required by individual business units.

The IT operations are located in India and the United States with its primary data center facilities co-located between New York and Texas. The company has a total of 60 AD forests:

1 main domain

55 domains have one-way trust relationships with the main domain

An additional 4 domains do not have any trust relationship with no future plans of establishing trust relationships with the other domains.

Users of different AD domains use different FQDN to access their corresponding file services. Additionally, the company does not plan to consolidate the AD domains and each domain uses a different IP subnet. The users of the domains with no trust relationships have a compliance archival requirement. The company wants to all data to be replicated between New York and Texas.

How many tenant Access zones will be required?



Answer : C

Question 3

Case Study 4

A company is experiencing a noticeable decrease in performance when accessing data on their Dell EMC Isilon cluster. The cluster hosts Microsoft Windows home directories and general purpose file shares. In addition, a file pool policy moves data that has not been modified in six months to an achieve tier. The administrator wants your assistance in understanding the reason for the slow data access. The number of users accessing the cluster has not changed.

The administrator has shared the following baseline metrics. The outputs were captured from a performance- acceptable time frame.

Trace route shows:

-3 hops between clients and the cluster

-Average latency is 3 ms

Iperf shows:

-940 Mb/s average bandwidth

-005 ms average jitter

Netstat on the local network shows:

-05% average re-transmission rate

Hostcache list:

-20 ms average roundtrip time across all clients

The administrator shows you the following output from the netstat command:

32366653 data packets (35556615947 bytes)

8010 data packets (9525723 bytes) re-transmitted

Based on the output, what information should be provided to the administrator?
