Question 1

Which of the following is part of an enterprise storage system's design criteria?&#10;A) Business continuity&#10;B) Redundancy and backup&#10;C) Performance and scalability&#10;D) All of the above

Accepted Answer

All of the options listed are crucial aspects of an enterprise storage system's design criteria. Business continuity ensures that the system can keep running or quickly recover in case of any failure. Redundancy and backup are essential for data protection, ensuring that there are copies of data in case of hardware failure or other issues. Performance and scalability are important to meet the current and future demands of the organization, allowing for efficient data access and storage expansion as needed.

Question 2

Which of the following is the fastest storage interface available today?&#10;A) InfiniBand EBR&#10;B) InfiniBand HDR&#10;C) FCoE&#10;D) iSCSI

Accepted Answer

InfiniBand HDR (High Data Rate) is currently the fastest storage interface, offering speeds up to 200 Gb/s, which is significantly faster than the other options listed.

Question 3

A NAS is available only to what protocol(s)?&#10;A) FTP, NFS, AFP, and SMB&#10;B) SMB only&#10;C) FTP only&#10;D) NFS only

Accepted Answer

NAS (Network Attached Storage) supports multiple protocols including FTP (File Transfer Protocol), NFS (Network File System), AFP (Apple Filing Protocol), and SMB (Server Message Block), allowing it to serve a wide range of devices and operating systems.

Question 4

Logical unit numbers (LUNs)serve what purpose in a storage area network (SAN)?&#10;A) They are unique identifiers for the SAN.&#10;B) They are the IP addresses of the file servers.&#10;C) Both a and b are correct.&#10;D) None of the above are correct.

Accepted Answer

LUNs are used to identify individual or logical partitions of storage within a SAN, allowing different devices to access specific storage areas. They are not unique identifiers for the SAN itself nor are they IP addresses of file servers.

Question 5

Which of the following is not a common cloud characterization?&#10;A)IaaS&#10;B)PaaS&#10;C)QaaS&#10;D)SaaS

Accepted Answer

QaaS (Quality as a Service) is not commonly listed among the standard cloud service models, which typically include IaaS (Infrastructure as a Service), PaaS (Platform as a Service), and SaaS (Software as a Service).

Question 6

What is the software that powers server virtualization technology in cloud computing?&#10;A)OpenFlow&#10;B)SNMP&#10;C)SDN&#10;D)Hypervisor

Accepted Answer

Hypervisor is the software layer that enables multiple operating systems to share a single hardware host, making it the core technology behind server virtualization in cloud computing.

Question 7

What cloud computing characterization would often be used by software developers?&#10;A)IaaS&#10;B)PaaS&#10;C)SaaS&#10;D)XaaS

Accepted Answer

PaaS, or Platform as a Service, provides a platform allowing customers to develop, run, and manage applications without the complexity of building and maintaining the infrastructure typically associated with developing and launching an app. This makes it an ideal choice for software developers.

Question 8

What are the Microsoft client and server virtualization technologies called?&#10;A)ZEN&#10;B)MS-ONE&#10;C)Azure&#10;D)Hyper-V

Accepted Answer

Hyper-V is Microsoft's virtualization technology for both client and server environments.

Question 9

What type of hypervisor would be loaded in a host OS in order to provide virtualization?&#10;A)Type-1&#10;B)Type-2&#10;C)Type-3&#10;D)Type-4

Accepted Answer

Type-2 hypervisors run on a host operating system to provide virtualization, unlike Type-1 hypervisors, which run directly on the host's hardware.

Question 10

What is the difference between SCSI and iSCSI?&#10;A) There is no difference between them.&#10;B) iSCSI allows Apple products to physically connect to SCSI hard drives.&#10;C) iSCSI makes the SCSI protocol available through IP networks.&#10;D) iSCSI provides wired connectivity to networked hard drives.

Accepted Answer

iSCSI (Internet Small Computer System Interface) extends the SCSI protocol to enable the use of the SCSI protocol over IP networks, allowing SCSI commands to be sent over LANs, WANs, or the Internet. This contrasts with traditional SCSI, which is used for direct connections to storage devices.
