Which of the following is NOT a technology for attaching data storage to a network?
a. DAS b. NAS c. RAS d. SAN |
c. RAS |
Reliability, Availability and Serviceability (RAS) |
|
|
_______typically consists of a dedicated file server that provides file sharing services over NFS or CIFS. |
NAS |
Network File System (NFS)
The Common Internet File System (CIFS) is the standard way that computer users share files across corporate intranets and the Internet.
Network-attached storage (NAS) |
|
|
True or False? DAS supports remote devices independently attached to a network. |
False |
Data attached storage
Direct-attached storage (DAS) is computer storage that is connected to one computer and not accessible to other computers. For an individual computer user, the hard drive is the usual form of direct-attached storage. |
|
|
What identity code is hard-coded into FC devices by their manufacturers?
a. MAC address b. LUN c. WWN d. Port number |
c. WWN |
FC = Fibre Channel |
|
|
An SAN uses two primary connection methods:_____ and_____. |
SCSI, Fibre Channel |
(Storage Area Network) An array of disk drives in a self-contained unit. |
|
|
True or False? An SAN transfers blocks of data instead of individual files. |
True |
A storage-area network (SAN) is a dedicated high-speed network (or sub network) that interconnects and presents shared pools of storage devices to multiple servers.
When a host wants to access a storage device on the SAN, it sends out a block-based access request for the storage device. |
|
|
What is the assigned code that identifies a specific block of data storage or a group of blocks on a disk drive?
a. MAC address b. LUN c. WWN d. Port number |
b. LUN |
Logical unit number (LUN) can refer to an entire physical disk, or a subset of a larger physical disk or disk volume |
|
|
Soft zoning uses______ to designate zones. |
WWNs |
Soft zoning is zoning which is implemented in software. |
|
|
True or False? The hosts that request access to SAN devices are initiators. |
True |
|
|
|
What is the term for the zoning applied at the port or HBA level using device LUNs?
a. Soft zoning b. Partitioning c. Hard zoning d. Fat provisioning |
c. Hard zoning |
A host bus adapter (HBA) is a device that connects multiple peripheral devices with a computer.
A host bus adapter is also known as a host adapter or host controller
LUN = logical unit number |
|
|
_______restricts access to SAN devices by hiding the LUN of storage devices. |
LUN masking |
Logical Unit Number Masking or LUN masking is an authorization process that makes a Logical Unit Number available to some hosts and unavailable to other hosts. LUN masking is mainly implemented at the host bus adapter (HBA) level. |
|
|
True or False? Storage provisioning is limited to formatting disk drives and assigning logical drive identifiers. |
False |
Storage provisioning is the process of assigning storage, usually in the form of server disk drive space, in order to optimize the performance of a storage area network (SAN). Traditionally, this has been done by the SAN administrator, and it can be a tedious process. |
|
|
What type of software provides failover protection to help ensure an SAN remains available to users?
a. Multipathing b. Auto-provisioning c. Authentication d. Backup/Restore |
a. Multipathing |
Multipathing is a technique that lets you use more than one physical path that transfers data between the host and an external storage device. In case of a failure of any element in the SAN network, such as an adapter, switch, or cable, ESXi can switch to another physical path, which does not use the failed component. |
|
|
Conventional provisioning is also known as_____ provisioning. |
Fat |
Fat provisioning (FP) is the conventional storage provisioning model, in which space is allocated beyond current needs, in anticipation of growing need and increased data complexity. As a result, the storage utilization rate is low. |
|
|
True or False? Thin provisioning allocates only the storage needed by current requirements. |
True |
Thin provisioning (TP) is a method of optimizing the efficiency with which the available space is utilized in storage area networks (SAN). TP operates by allocating disk storage space in a flexible manner among multiple users, based on the minimum space required by each user at any given time |
