  Which component of an archiving solution is responsible for scanning data that can be archived based on a policy?

  A. Archiving agent
  B. Archiving server
  C. Archiving policy server
  D. Archiving storage device
  A. Archiving agent

  Archiving Solution Architecture Archiving solution architecture consists of three key components; archiving agent, archiving server, and archiving storage device.

  

  An archiving agent is software installed on the application server. The agent is responsible for scanning the data that can be archived based on the policy defined on the archiving server. After the data is identified for archiving, the agent sends the data to the archiving server. Then the original data on the application server is replaced with a stub file. The stub file contains the address of the archived data. The size of this file is small and significantly saves space on primary storage. This stub file is used to retrieve the file from the archive storage device . An archiving server is software installed on a host that enables administrators to configure the policies for archiving data. Policies can be defined based on file size, file type, or creation/modification/access time. The archiving server receives the data to be archived from the agent and sends it to the archive storage device. An archive storage device stores fixed content. EMC E10-001 Student Resource Guide.

• Question 185:

  What is a function of the Fibre Channel Forwarder (FCF)?

  A. Checks the Ethertype of FC frames
  B. Forwards Ethernet frames to an IP network
  C. Encapsulates and de-encapsulates FC frames
  D. Forwards FC frames to an IP network
  C. Encapsulates and de-encapsulates FC frames

  FCoE Switch An FCoE switch has both Ethernet switch and Fibre Channel switch functionalities. The FCoE switch has a Fibre Channel Forwarder (FCF), Ethernet Bridge, and set of Ethernet ports and optional FC ports. The function of the FCF is to encapsulate the FC frames, received from the FC port, into the FCoE frames and also to de-encapsulate the FCoE frames, received from the Ethernet Bridge, to the FC frames.

• Question 186:

  In a Microsoft Windows file sharing environment, what is a function of system access control lists (SACL)?

  A. Determines object access information that needs to be audited
  B. Provides information on system access troubleshooting
  C. Uniquely identifies objects, users, and user groups
  D. Provides path name to access both inbound and outbound traffic
  A. Determines object access information that needs to be audited

  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.

• Question 187:

  What is needed to perform a non-disruptive migration of virtual machines (VMs) between hypervisors?

  A. Hypervisors must have access to the same storage volume
  B. Physical machines running hypervisors must have the same configuration
  C. Hypervisors must be running within the same physical machine
  D. Both hypervisors must have the same IP address
  A. Hypervisors must have access to the same storage volume

  VM Migration: Hypervisor-to-Hypervisor

  

  In hypervisor-to-hypervisor VM migration, the entire active state of a VM is moved from one hypervisor to another. This method involves copying the contents of virtual machine memory from the source hypervisor to the target and then transferring the control of the VM's disk files to the target hypervisor. Because the virtual disks of the VMs are not migrated, this technique requires both source and target hypervisor access to the same storage.

• Question 188:

  Click on the calculator icon in the upper left corner.

  If a disk drive's rotational speed is 10000 revolutions per minute, what is its average rotational latency?

  A. 0.003 milliseconds
  B. 0.05 milliseconds
  C. 3 milliseconds
  D. 5 milliseconds
  C. 3 milliseconds

  ---

  Rotational Latency

  

  Calculation

  Rotational Latency = 0.5 / (RPM / 60) = 0.5 / (10000 / 60) = 0.5 / 166.666 = 0.003 Seconds = 3 msec

  EMC RecoverPoint

  

  RecoverPoint is a high-performance, cost-effective, single product that provides local and remote data protection for both physical and virtual environments. It provides faster recovery and unlimited recovery points. RecoverPoint provides continuous data protection and performs replication between the LUNs. RecoverPoint uses lightweight splitting technology either at the application server, fabric, or arrays to mirror a write to a RecoverPoint appliance. The RecoverPoint family of products include RecoverPoint/CL, RecoverPoint/EX, and RecoverPoint/SE.

  RecoverPoint/CL is a replication product for a heterogeneous server and storage environment. It supports both EMC and non-EMC storage arrays. This product supports hostbased, fabric-based, and array-based write splitters. RecoverPoint/EX supports replication between EMC storage arrays and allows only array-based write splitting.

  RecoverPoint/SE is a version of RecoverPoint that is targeted for VNX series arrays and enables only Windows-based host and array-based write splitting.
