• Question 311:

  Which security feature is available in a Microsoft Windows file sharing environment using Network Attached Storage?

  A. Windows Security Identifier (SID)
  B. Discretionary Access Control Lists (DACL)
  C. Operating System Control Lists (OSCL)
  D. Global Unique Identifier (GUID)
  B. Discretionary Access Control Lists (DACL)

  NAS File Sharing: Windows ACLs Windows supports two types of ACLs: discretionary access control lists (DACLs) and system access control lists (SACLs). The DACL, commonly referred to as the ACL, that determines access control. The SACL determines what accesses need to be audited if auditing is enabled.

  In addition to these ACLs, Windows also supports the concept of object ownership. The owner of an object has hard-coded rights to that object, and these rights do not need to be explicitly granted in the SACL. The owner, SACL, and DACL are all statically held as attributes of each object. Windows also offers the functionality to inherit permissions, which allows the child objects existing within a parent object to automatically inherit the ACLs of the parent object.

  ACLs are also applied to directory objects known as security identifiers (SIDs). These are automatically generated by a Windows server or domain when a user or group is created, and they are abstracted from the user. In this way, though a user may identify his login ID as "User1," it is simply a textual representation of the true SID, which is used by the underlying operating system. Internal processes in Windows refer to an account's SID rather than the account's username or group name while granting access to an object. ACLs are set by using the standard Windows Explorer GUI but can also be configured with CLI commands or other third- party tools. EMC E10-001 Student Resource Guide.

• Question 316:

  In a Fibre Channel (FC) SAN, which protocol implementation is used?

  A. SCSI over FC
  B. SCSI over FCoE
  C. FC over iSCSI
  D. FC over SCSI
  A. SCSI over FC

  ---

  FC Architecture Overview The FC architecture represents true channel/network integration and captures some of the benefits of both channel and network technology. FC SAN uses the Fibre Channel Protocol (FCP) that provides both channel speed for data transfer with low protocol overhead and scalability of network technology.

  FCP forms the fundamental construct of the FC SAN infrastructure. Fibre Channel provides a serial data transfer interface that operates over copper wire and optical fiber. FCP is the implementation of SCSI over an FC network. In FCP architecture, all external and remote storage devices attached to the SAN appear as local devices to the host operating system.
