Which SMI-S term provides information about physical and logical SAN entities found, often dynamically, within the management domain?
A customer's switch command line indicates that the status of port 4 is isolated. You know that port 4 is connected to a target device. What is the problem?
Which two link speeds are supported by SATA devices? (Choose two)
Company.com needs to backup its data while keeping the data online. Cost and application performance are both important. The data can be backed up to tape between 12.00 AM and 6.00AM when the applications are not write intensive. Which solution is the most appropriate?
Create a copy on write snapshot, mount the snapshot to a different host, back the snapshot up to tape.
A customer has a SAN consisting of two FC switches with a single 4Gb/s ISL between them. There are six hosts attached to one switch, with an average throughput of 30MB/s each, and a single storage subsystem port connected to the second switch at 2Gb/s. The deployment is performing poorly and you have been tasked with identifying the possible cause. What is the cause of the degraded performance?
You have been asked to conduct a high-level inventory of a remote fibre channel SAN fabric. Your manager is worried that the remote site may include HBAs manufactured from a now bankrupt vendor. What information will be most useful to you to determine the HBA vendor?
World Wide Port Name
Which standard management agent resides in the file/record layer if the SNIA storage object model?
Which hardware component provides the interface between the storage network and the server backuplane?
host bus adapter
What are two advantages of virtualization? (choose two)
Provides higher storage asset utilization
Increase the number of storage devices an operator can manage
In a multiple switch fabric, how should the error detection (E_D_TOV) and resource allocation (R_A_TOV) time out values be set?
the same on all N_Ports and switches in the fabric
Which Fibre Channel topology was initially introduced as a replacement for physical SCSI?
What is the maximum distance of a 50- micrometer multimode fibre with a 850nm shortwave laser at 2 Gbps?
Identify the zoning object that is hardware enforced.
Which disk drive type relies on the host processor to perform all storage tasks?
A storage configuration was created which stores large amounts of infrequently used documents. The storage implementation is based on serial attached SCSI (SAS) and an edge expander. Almost all ports are utilized, and a second edge expander will be installed. What is required to connect SATA devices to the SAS domain?
cable with two SATA connectors
An application administrator seeks to improve the I/O performance of the server's SAN-attached storage. Which HBA parameter setting change can affect the performance?
Which activity is performed by a storage device manager?
logical unit number (LUN) masking
What is the minimal iSCI security level needed to protect against man-in-the-middle insertion, modification or deletion?
Digest for header and data integrity
Which component in an IP storage application requires configuration management?
Which two components are required in a specialized NAS operating system? (choose two)
In Fibre Channel, what does the port type FL mean?
What type of Fabric switch ports are joined to form an ISL?
E_Port to E_Port
What determines the principle switch in a Fibre Channel Fabric?
Which protocol is used to allow as NAS device to backup to a LAN attached backup device?
Which subset of target devices allow for scalability in the SCSI protocol?
Which two recovery risks exist, given backup of a multi-protocol NAS device taken from a client System through an active share? (choose two)
Loss of NFS meta data
Loss of ACL information
Where is LUN masking is performed?
Which three Fiber Channel components have World Wide Names? (Choose three)
Storage device port
Physical port in a switch
What describes RAID 5?
What does the acronym PCI mean?
Peripheral component interconnect
A company with departmental Fibre Channel SANs has decided that they now want to merge them into a large enterprise SAN to assist with resource allocation and improve resource utilization. What two (2) configuration parameters should the administrator check before connecting the SANs to minimize service disruption? (Choose two.)
verify time out values match
verify domain ID assignments are unique
What are two protocol options for transporting Fibre Channel over an IP network? (choose two)
Which IP Storage solution supports presentation of storage to an array of blade servers that Require remote boot, high storage availability, and minimal peak I/D requirements?
What occurs when iSCSI has been implemented in software?
Host CPU overhead increases.
What are two advantages of a switched fabric over arbitrated loop topology? (choose two)
Failure of a single device in a switched topology affects only that device.
Number of devices that can be attached increases as the size of the switching structure expands.
What is the maximum distance of a 9-micrometer singlemode fiber with a 1300nm longwave laser at 2 Gbps?
Which two are recognized by SNIA as elements of the storage virtualization taxonomy? (Choose two.)
What does a NAS head do?
It connects to block storage devices
Which component is a configuration management element of a host?
What the steps to restore a complete backup that is using incremental method and has run three times already?
latest full and subsequent incremental backups must be restored
What is the function of zoning?
Allows certain N ports to be visible to each other
You must implement a backup infrastructure for a remote office. This office has enough data to fill a single tape each night.
