What is the correct sequence of steps to change all physical and group IPs on the members to the new subnet?

Question30: A customer has several datacenters on a small campus with full 10 GbE links between all datacenters. The customer needs to provide data protection to easily retrieve data in case of errors/deletions. The customer needs to protect data changes as quickly and often as possible to provide the greatest protection for recent changes.
What is the simplest solution that meets ALL requirements?

Question31: A technician needs to add a new PS Series array to existing PS Series storage. Due to lack of switch ports, the technician does NOT connect the dedicated management ports on the new member. The technician has configured a dedicated management port on all existing members.
Which two options provide a recommended solution? (Choose two.)

Question32: A customer has a single-member group with a RAID policy of RAID 6 in the default storage pool. A second member with a RAID policy of RAID 10 is added.
What are two valid ways to add the second member? (Choose two.)

Question33: When does a VLAN ID need to be configured on Dell PS Series arrays?

Which two options enable the PS Series array to reclaim space from the deleted data? (Choose two.)

Question35: A customer has a large complex VMware environment connected to a PS Series group. The group runs multiple arrays with two storage pools. The administrator notices performance and connection issues in the environment. After checking SAN HQ, the administrator notices the number of allowed connections has exceeded the maximum connections to the pool.
Which three steps should be taken to fix this problem? (Choose three.)

Question36: A VMware administrator requests the creation of a 100 GB volume to use as a datastore on an ESX environment. The SAN administrator completes the request. For a few days, the VMware administrator is able to access and use the datastore. The VMware administrator then reports that the VM located on the datastore is greyed out and labelled as inaccessible.
What are three possible reasons for this problem? (Choose three.)

Question37: An installer needs to set up a PS Series group using the recommended iSCSI network architecture.
What is required for this setup?

Question38: A SQL administrator needs to deploy two databases: one for sales transactions and one for inventory.
Which two topologies prevent a Torn Smart Copy from being created if one of them were restored with Auto Snapshot Manager? (Choose two.)

Question39: An installer sets up multiple volumes on a PS Series group and uses CHAP for access control. A host can NOT access the volume named TESTVOL. The host can see the volume target name in its iSCSI initiator and another server on the same subnet can access it.
What is the probable cause of this issue?

Question40: A customer reports that a problematic array is acting up. The customer is able to open SAN HQ and provide a SAN HQ archive, but is unable to get to the Group manager GUI to initiate a diag log pull. The customer tries to use the Group IP address via FTP to retrieve previous diagnostic files, but that is also unsuccessful.
What other option should the customer use to retrieve logs?

Question41: An administrator needs to change the RAID type from RAID 10 to either RAID 50 or RAID 6.
What must the administrator select before Modify RAID Configuration within the Activities pane?

Question42: A technician has installed the Host Integration Toolkit (HIT/Microsoft) kit.
Which two configurations should the technician set in Auto Snapshot Manager (ASM)? (Choose two.)

Question43: A new storage administrator (SA) is configuring replication on a newly created 1 TB volume. Management determines that asynchronous replication will be used.
The new volume has 200 GB of used space.

There is only 100 GB of space available on the DR group.

Delegated space has only 50 GB of space still available.

The SA looks at the delegated space on the DR group and determines that there is NOT enough room to fit the replica set for the new volume.
Which action should the SA take at the DR site so that the new volume can be replicated?

Question44: An engineer needs to migrate a volume from a live production pool to a newly created pool, but is unable to do so.
What must the engineer do before the migration can start?

Question45: A customer has an existing group with a single PS6210X member array configured as RAID 6. SAN HQ shows that the array is handling a very high level of IO. The database admin reports higher than normal latency for disk access. The same system ran in the past without problems for months, but it is gradually starting to get worse. The customer has allocated only 20% of the useable space on the array. The customer needs to improve performance with the LEAST impact on production.
Which two options should the customer consider? (Choose two.)

Question46: A customer has a multi-member, multi-pool group in production. The load on the pools is NOT balanced.
Which two methods should a SAN administrator use to balance the load between the pools? (Choose two.)

Question47: A customer needs 36 TB of storage space for an upcoming SAN implementation.
Which two volume distributions are valid? (Choose two.)

Question48: An installer deploys a new environment that consists of a single hybrid array with a mix of SSDs and 10K disks. The installer initially connects several servers that run transactional data. The installer then migrates a large amount of file data to the new array. The servers perform very well for the first few hours. The performance then drops suddenly and significantly. The database administrator reports that the latency has suddenly increased beyond what was expected.
What is the cause of the sudden drop in performance?
