Parity __1__ and dParity __1___ Data __1___ Spares _24____ Broken __0___ - answer-How many disks are reported in each of the four states on the 7Node1 storage controller? Aggregates and Disks - answer-When you expand a cluster node and Storage, what two hardware components can you manage for the cluster node? 4 - answer-How many network interfaces are installed on the system board of the storage controller? 0 - answer-How many additional network interfaces are installed in expansion slots? 2 - answer-How many network interfaces are enabled and configured with IP addresses? Parity Dparity Spares Broken - answer-Besides "data" disks, what other three "State" types are reported on the disks? SSD FC-AL - answer-Of the four possible types of disks, which types of disks are installed on the cluster nodes? Microsoft Windows domains allow for differing time zones, as long as date and time across time zones are synchronized - answer-Time Zone Synchronization The zoneinfo database, which is a collaborative compilation of time zone information, has a special area referred to as "Etc". The Etc area is used for administrative zones, particularly for the "Etc/UTC" which represents Coordinated Universal Time. - answer-Etc/UTC The date command sets the date and time on all nodes in the Data ONTAP cluster. This synchronization among nodes ensures a consistent time setting across all nodes in the cluster. - answer-Date Block Level - answer-NAS provides file-level access; what does SAN provide? True - answer-WWPNs are added to FC groups? False - answer-WWNNs are added to FCoE igroups? False - answer-WWPNs are added to iSCSI igroups? A data LIF on a vserver that is configured for the FC or iSCSI protocol. - answer-In 7-mode, the target is a physical FC HBA or Ethernet port on the controller. In clustered Data ONTAP, the target is? Multipath software is not installed. Multipath software is not licensed and enabled. - answer-To guarantee fault tolerance, you have implemented multiple paths to the LUN. Now, from the initiator, you see two disks when you should see only one. What might be wrong? Interoperability Matrix Tool - answer-What is the best location to investigate the details of supported configurations? False - answer-A storage system can be configured to communicate with only one initiator at a time. False - answer-So that the initiator can discover the FC target, you must enter the login command. True - answer-Clustered Data ONTAP has a logical layer, called a LIF, between the HBA hardware and the WWPN. True - answer-Clustered Data ONTAP LIFs connect to FC initiators through the FC switch in the same way that a physical HBA connects. Create an iGroup on the initiator Enter and FC command to trigger discovery - answer-Which of the following actions are not included in the seven steps for implementing an FC or FCoE SAN on a NetApp storage system? Port 3260 - answer-iSCSI connectivity between an initiator and a Data ONTAP storage system requires which port to be open? After discovering a target portal, the target remains inactive until connected. - answer-Which of the following statements about iSCSI connectivity is true? LUN masking - answer-What is another name for the LUN mapping step? LUN Mapping - answer-The process of associating a logical unit to an igroup? Igroup - answer-A grouping of initiators associated with a operating system type? Logical Unit - answer-A container that will be presented as a disk to an initiator? Create a LUN Create an igroup Map the LUN to an igroup - answer-Identify the steps that are required to present a LUN to an initiator? True - answer-As of Data ONTAP 8.2, fractional reserve is an option that uou can set 0 or 100 False - answer-Only when data is written to a LUN is there space allocated for that LUN within the aggregate. False - answer-Overwrite reserve is used immediately after a LUN is overwritten, even if there is space avaliabale in the active file system. True - answer-The overwrite reserve is equal to the snapshot copy size multiplied by the fraction reserve percentage. Volume snapshot autodelete modify Volume autosize - answer-In clustered Data ONTAP, what two commands can be used to set the space-management policy for a volume? 4 - answer-If there is one target port available on each controller in a high-availability, single_image controller configuration and two ports on the initiator host, how many paths are available to a properly mapped LUN? False - answer-If more than one path is available, there is no need for a Device Specific Module (DSM)? False - answer-Paths that travel over the interconnect are preferred to paths that are directly connected? Install an interconnect cable between the storage failover pairs. Create a LIF per node per fabric. Install the FC license on the cluster. - answer-What tasks are required to prepare a clustered Data ONTAP Vserver for an HA, FC multipath SAN implementation? MPIO and MCS are features of the MPIO protocol MSC allows you to combine several connections inside a single session Clustered Data ONTAP does not support MCS Data ONTAP support MCS - answer-Which statements are true about iSCSI MCS? False - answer-MCS is support out of box on Data ONTAP and doesn't require any configuration False - answer-MCS is the only method for multipathing iSCSI. Igroup create - answer-Which storage system command should be used to group initiators to allow them to be mapped to LUNs? Available space = 100 GB, used space = 100 GB, and reserved space = 0. - answer-A space-reserved LUN of 100 GB is created in a volume with a total size of 200 GB. There is nothing else in the volume, and no snapshot copies have been made of the volume. The fractional reserve for the volume is set to 100 percent and the snap reserve is set to 0. In a 7-mode system, what are the correct values for available space used space and reserved space? Single-Image - answer-Which is the only valid setting to which the cfmode can be set in Data ONTAP 7.3 and later? DSM (Device Specific Module) - answer-When implementing Microsoft MPIO, what is also required in addition to the MPIO drivers? Verify connectivity at the switch, if present. - answer-LUNs that were previously available can no longer be seen from a host system. These LUNs can still be viewed from a storage system. They are mapped to the correct igroup and are online. What next step could you take to determine the problem? Unified Storage - answer-Which term is used to indicate that both NAS and SAN protocols are present on the same storage system? Initialized - answer-Before you partition a LUN in Windows with Disk Management, it must first be? Multiple Connected Session (MCS) - answer-Which type of multipathing creates multiple paths within a single iSCSI session? They are utilities installed on a host for obtaining information about hosts, switches and storage systems. - answer-Which of the following statements is true of the host utilities? Solid-State drives currently cost less than hard disks - answer-Which statement is NOT true about solid-state drives (SSDs) and hard disk drives (HDDs)? Public - answer-Which cloud services refer to infrastructure or applications hosted by service providers and are offered a services to enterprises? NAS and SAN - answer-Which two technologies can Data ONTAP support simultaneously? DAS - answer-Acme Company is a storage provider that provides localized file sharing in environments with few servers that do not need to share information over long distances or across an enterprise. Which storage technology is the best choice? - answer-Which two Netapp products positively impact storage utilization? SnapMirror SnapRestore SnapVault FlexClone - answer-Which Netapp products incorporate Netapp Snapshot Technology? - answer-Which two Netapp technologies, when combined,, optimize storage efficiency?
