EMC Isilon Design Specialist Exam for Technology Architects 認定 E20-554 試験問題:

1. Refer to the exhibit.

Which tool was used to create this output and what is the most significant characteristic?

A) isi_netlogger and moderate metadata read operations
B) nfsstat and read-intensive access
C) nfsstat and write-intensive access
D) iostat and write-intensive access

2. -- Exhibit -
A large manufacturing company is an existing Isilon customer with a cluster consisting of four NL400 nodes with 4TB drives. The cluster is using N+2:1 protection level and the file system shows that it is 60% utilized. Home directories and file shares comprise 75% of the existing content and the remainder is inactive deep archive. The company has 1,000 employees using Windows and Mac clients participating in a single Active Directory (AD) forest.
During a meeting with the CIO and Director of IT you discuss the company's recent acquisition - an engineering firm that specializes in Computer Aided Design (CAD). The engineering firm has 400 UNIX workstations that produce technical drawings which are currently stored on another vendor's SAN solution. The all UNIX environment uses NIS for authentication and name resolution. They do not currently use DNS or LDAP. The engineering company has an old storage system that has been experiencing problems and the CIO would like you to migrate the data onto the Isilon cluster. The CIO would like to eliminate all tape and recover the data onto disk.
The CIO is concerned about security of the company's intellectual property, especially with the rapid adoption of mobile devices and external cloud content sharing services such as DropBox, Egnyte, and SugarSync. They would like to implement an alternative that provides external file sharing and mobile device synchronization while maintaining security control over the company's data.
The Director of IT reports that users are storing non-work related content on the Isilon cluster. They would like to limit the amount of capacity that each user can consume in their home directory and want to ensure you provide the capability to easily visualize which users are over their allotment. The company's Windows users currently leverage Windows Shadow Copy to recover files that have been accidentally deleted. The IT department wants to ensure that Mac and incoming UNIX clients have the same functionality.
The Director of IT also mentions that users are reporting slow response times when browsing their home directories and shared folders. They are concerned that Isilon cannot scale to support their combined requirements.
The customer provides the following environment summary from the engineering firm's recently departed IT staff:
20 TB of Home Directory data
100 TB of active CAD projects
400 TB of archived data stored on tape at an offsite warehouse
-- Exhibit -
What steps would you recommend to the IT Director to allow for collaboration between the engineering company and the manufacturing company?

A) Create a new pool for use by the collaboration users.
Set up Access Zones on the Isilon cluster using AD and NIS authentication.
B) Set up Access Zones on the Isilon cluster using Active Directory (AD) and NIS authentication.
Create directories and apply user group permissions from AD and NIS for each collaboration
team.
C) Repoint the engineering users to the Active Directory controller
Add the users to the appropriate Active Directory security group.
D) Upload a collaboration user csv file into the cluster with usernames and passwords for the
collaboration directory.

3. A potential customer has about 540TB of NetApp running in ONTAP 7-Mode. They are willing to let you gather some workload data. They have LDAP and Active Directory authentication and primarily Windows Clients. They are very interested in Automated Tiering and Large Scale Archives. They are not certain about the workflows from the Marketing Department. The Content Team will only say they need to acquire 300 TB within 90 days. They do not know the average file size or the number of aggregates they are managing.
Which tools would you use to gather information to do your Isilon sizing?

A) Isilon Insight IQ, OnCommand Insight, and nfsstat
B) isi status, isi_netlogger, and PerfMon
C) Wireshark, isi statistics, and iostat
D) MiTrendWPA ,Autosupport, and PerfCollect

4. You will be meeting with the Corporate Security Team as part of the implementation planning for a new Isilon cluster deployment. The Lead Security Analyst has asked you to discuss the Authentication Sources on your Isilon Cluster.
What customer questions regarding Isilon-supported Authentication Sources do you need to be prepared to answer?

A) Are you using File Services for UNIX in your AD environment?
Do you support NIS+ for NFS authentication?
Do you support multiple Access Zones connecting to the AD Domain?
B) What mechanism are you using for NFS authentication?
Do you support Novell Directory Services?
What implementations of LDAP are supported?
C) Is the cluster X.400 compliant?
What firewall rules are in place to prevent data leakage?
Is there a audit trail for access zone configuration changes?
D) What mechanism are you using for NFS authentication?
Do you have multiple AD domain support?
What versions of LDAP are supported?

5. When designing Isilon solutions, which issue should you pay special attention to?

A) Conduct stakeholder interviews
B) Follow all SSD sizing rules
C) Meet customer expectations
D) Create a workflow document
