It stores metedata in Inodes. What is an INode - answer-Index Node Pointers to the block on disk that hold the actual data. Every file has a INode and each volume has a hidden INode. RAL (Remote Access Layer) - answer-A feature in ONTAP software that sits on top of the WAFL layer and is used to direct remote traffic in a FlexGroup Volume FlexVol - answer-a data container associated with a Storage Virtual Machine (SVM) with FlexVol volumes. It gets its storage from a single associated aggregate, which it might share with other FlexVol volumes or Infinite Volumes. It can be used to contain files in a NAS environment, or LUNs in a SAN environment. System Memory - answer-Memory that is not backed up NVRAM - answer-(Non Volatile Random Access Memory) Ram that is battery-backed Consistency Point - answer-The point at which the data system memory is committed to disk. When a client reads or writes to a volume that is on a node other than the node that the client is connected to, access is said to be: - answer-indirect for reads and writes HBA - answer-Host Based Adapter FlexCache Volume - answer-A caching technology that creates sparse, writeable replicas of volumes on the same of different ONTAP clusters. FlexCache software supports cahce access to what types of clients? - answer-NFSv3 and SMB FabricPool - answer-A data fabric technology powered by NetApp that enables automated tiering of data based on how frequently the data is accessed. FabricPool technology moves data based on access patterns between what two locations? - answer-Local Tier (aggregate) and a cloud tier Which name is the name of a predefined cluster role: admin, root, svadmin, vsadmin? - answer-admin Which LIF is used to access ONTAP System Manager? - answer-Cluster Management LIF During cluster creation process what account is created automatically? - answer-admin SVM How many admin SVMs are created to represent a cluster? - answer-One This is the minimum number of data SVMs a cluster must have to serve data to its clients. - answer-One What happens if a failure occurs on the node that the management LIF is connected to? - answer-The LIF will failover to another node in the cluster. (failover is only for NAS LIFs. SAN LIFs do not fail over) Step 1 in configuring a new cluster is - answer-Cluster Initialization (includes setup of cluster node management networks and cluster management accounts) Step 2 in configuring a new cluster is - answer-Create Local Tiers from available disk or SSDs on the node Step 3 in configuring a new cluster is - answer-Configure networking Step 4 in configuring a new cluster is - answer-Enable Protocols and create network interfaces to access the storage Step 5 in configuring a new cluster is - answer-Provision the storage What are the two levels of data protection provided by System Manager? - answer-Local and remote In System Manager what are the remote protection policies offered? - answer-Asynchronous replication, Synchronous replication, and SnapMirror Business Continuity What port speed is supported for cluster interconnect? - answer-10GB LIF Failover - answer-An automatic migration of a LIF from one network port to another LIF Migration - answer-The process of moving a LIF from one network port to another port LIF revert - answer-Return of a failed-over or migrated LIF to its home port (can be done manually or automatically Which two items can a LIF represent? - answer-IP Address and a WWPN (World Wide Port Name) What are the four types of Storage Virtual Machines (SVM) in a cluster? - answer-Admin Storage VM, Node Storage VM, System Storage VM, Data Storage VM What two ONTAP software features can increase volume efficiency? - answer-Deduplication and Data Compression What What two ONTAP software features can increase flash efficiency? - answer-Aggregate Level inline deduplication and Inline data compaction Which data compression methods are available in ONTAP software? - answer-inline and postprocess Which upgrade type can group HA pairs that are upgrade together? - answer-batch and automated I/O operations can be categorized into what two categories? - answer-Random or Sequential Which feature can you configure to prevent workloads or tenants from negatively from effecting each other's performance? - answer-Performance Service Level Which component connects FAS or AFF controller to form a multinode cluster? - answer-Cluster Interconnect Which part of storage architecture is a logical storage resource: aggregate, FlexVol Volume, drive, RAID group? - answer-FlexVol Volume How many parity disk are there in a RAID DP aggregate that was created using 44 dis and a RAID group size of 15? - answer-6 How odoes the NetApp file system WAFL use NVRAM? - answer-NVRAM enables write operations to be acknowledged to to the client before being written to disk Which two condition trigger a consistency point (CP)? - answer-10 second timer expires or NVRAM buffer fills up How does a client nondisruptibvely access a volume that has been moved to a node that is in a cluster other than the node to which the clien is connected? - answer-Through an indirect path over the cluster interconnect
