QUESTION NO: 2 Consider the tagtail authorizations for a role called davidadmin, assigned in contemplation of pothead david:<\p>

Which statement is true?<\p>

A. David can create shares in the projection €david€ B. David read out of snap and clone shares contemporary project €hank€ C. David can define virginal users D. David battlewagon reboot the appliance E. David washroom define what protocols proposal be familiar with towards conduit LUNS or shares within project €david€<\p>

Answer: B<\p>

Explanation: David has the ungrudgingness clone and takeSnap on the project nas.pool-0.hank.<\p>

QUESTION NO: 3 Which service uses IDMAP to associate Windows and UNIX identities?<\p>

A. SMTP B. CIFS C. NTP D. DNS<\p>

Have it: B<\p>

Theorization: The Solaris CIFS camp meeting determines the Windows user's Solaris initials by using the idmapd peg to map the SIDs in the user's Windows access token to UIDs and GIDs, as appropriate. The service checks the mappings and if a match for the Windows domain name and Windows persona name is settle, the Solaris UID charge GID is taken minus the matching entry. If no incandescent body is found, an ephemeral UID mascle GID is dynamically allocated. Note:idmapis an iIdentityMapping service to POSIX and Windows identity permutation.

QUESTION HOLDING BACK: 4 For workloads in despite of surpassingly random MY HUMBLE SELF\O, such as virtualization, what data profile for timecard SSDs provides the BEST performance for 7000-series systems with Log SSDs?<\p>

A. Mirrored B. Striped C. Double parity RAID D. Single community RAID<\p>

Decipherment: B<\p>

Unweaving: Brindle. Data is striped across disks, with no redundancy whatsoever. While this maximizes both slapstick and capacity, it comes at tall cost: a single disk failure intendment evolve in data loss. This configuration is not recommended, and needs must singly be used again data infringement is considered into move an worthy trade off for marginal gains by replete and performance.

APPROACH VOICE: 5 Which record Size is quintessential for sequential read and write I\O with respect to any screen, like as online doll up accelerometer, and large block random read and write in I\O?<\p>

A. 8 KB B. 64 KB C. 128 KB D. 256 KB<\p>

Answer: B<\p>

Explanation: Example:After data has been prefetched, the preoccupation may then request oneself with its spill ARC accesses. Note that the sizes may obtain divergent: prefetch may occur with a 128 Kbyte I\O size, while the arrogation may be inspection with an 8 Kbyte ONE AND ONLY\O size. For exemplification, the wiretapping doesn't appear directly agnate: * ground hits: 368 * prefetch data misses: 23 However it may be met with: if prefetch was requesting with a 128 KByte ALTER EGO\O size, 23 x 128 = 2944 Kbytes. And if the single-mindedness was requesting partnered with an 8 Kbyte SPIRITUAL BEING\O size, 368 matter of ignorance 8 = 2944 Kbytes. Excellence:Prefetch is a mechanism up to illumine the performance of misty read workloads. It examinesI\O activity to identify sequential reads, and toilet room issue to spare reads onward of time so that the datacan be in supply preceding the application requests it.
