Question 1:

When reviewing the actual protection output of N 4/2, what does the number “4” represent?

A. FEC stripe units per stripe

B. Hard drives used per stripe

C. Volume stripes per file system

D. FEC stripe units per file system

Correct Answer: A

It\’s OneFS FEC protection nomenclature for our “hybrid” protection polices. More generally, it\’s written as:

N M/b

where “N” is the number of data stripe units in a stripe, “M” is the number of FEC stripe units in a stripe, and “b” is the number of stripe units in a stripe which are allowed to reside on the same node.

Question 2:

In Isilon OneFS, what is a characteristic of CoW with snapshots?

A. Used for small changes, inodes, and directories.

B. Avoids the double write penalty.

C. Increases file fragmentation.

D. Used for more substantial changes such as deletes.

Correct Answer: A

With copy on write, as the name suggests, a new write to HEAD results in the old blocks being copied out to the snapshot version first. Although this incurs a double write penalty, it results in less fragmentation of the HEAD file, which is better

for cache prefetch, etc.

Typically, CoW is most prevalent in OneFS and is primarily used for small changes, inodes and directories.

Question 8:

An Isilon administrator is receiving “permission denied” while accessing a file on a cluster that an end-user created through an SMB share. The end-user is unable to access the share from their UNIX server. The end-user “mydomain.com \win_user1” as the login name to access the Microsoft Windows share and then used an LDAP account name of “ux_user1” to access the UNIX mount. The Isilon cluster is joined to the “mydomain.com” Active Directory domain. In additional, the cluster has an LDAP provider attached to it while the on-disk identity is set as “Native”.

What is a possible cause for this permission issue?

A. Usermapping rule is not present.

B. RFC2307 is not configured on the Active Directory.

C. On-disk identity is set as “Native”.

D. Fake UID generation in the cluster is disabled.

Correct Answer: B

Question 9:

A company deployed an Isilon cluster that consists of eight nodes connected to a main production subnet by all available 10GB ports. Later, the company decided to implement a disaster recovery solution with a separate replication subnet. During the reconfiguration, one of the 10Gb ports from each of the nodes 1-4 was moved into the new pool and SBR was activated. After activating the replication policies, the administrator noticed that the main production ports on nodes 1-4 reached the bandwidth limit. What is a possible reason for this behavior?

A. Default gateway for the replication subnet has a higher priority value.

B. Default gateway for the replication subnet is not specified.

C. Default gateway for the replication subnet has a lower priority value.

D. Main production ports have a smaller bandwidth limit than replication ports.

Correct Answer: B
