質問 # 16
A department has a business requirement that all their backups are encrypted to prevent data from being read during the transmission to the server and also once written in the storage pool. Which encrypted method satisfies all those requirements?
- A. tape drive encryption
- B. server-side encryption
- C. SSL encrypted communication
- D. client-side encryption
正解：D
解説：
According to IBM's documentation12, client-side encryption is a method of encrypting data before it is sent to the server for backup or archive operations. Client-side encryption uses a password that is entered by the user to generate an encryption key. The password needs to be confirmed when encrypting the file for backup, and also needs to be entered when performing restores of encrypted files12.
Client-side encryption satisfies all the requirements of encrypting data during transmission and storage, because:
It prevents data from being read during transmission, because the data is encrypted before it leaves the client system3.
It prevents data from being read once written in the storage pool, because the data remains encrypted on the server and can only be decrypted with the password that is known by the user3.

According to IBM's documentation1, server-side deduplication is the process of removing redundant data during a backup operation on the server system. Server-side deduplication is especially effective when you want to conserve disk space on the server storage pools.
To optimize the performance of server-side deduplication, two items that should be examined are:
The storage for the database provides sufficient IOPS. IBM recommends using a high-performance disk for the database and ensuring that it has a minimum capability of 3000 IOPS1.
The server has sufficient memory. IBM recommends allocating at least 1 GB of memory for each TB of data that is backed up each day2.
質問 # 21
A file is backed up once and then inadvertently deleted. Ten days later the mistake is discovered. Which backup copy group option must be set properly to be sure the file can be restored?
- A. RETDELETED
- B. RETMIN
- C. RETONLY .
- D. RETEXTRA
正解：D
解説：
To restore a file that was inadvertently deleted, you need to have a backup copy of the file available. The RETEXTRA option in a backup copy group specifies that extra versions of files are kept even if the files are deleted from the active file system. This means that older versions of files are retained beyond their normal retention period, allowing you to restore files that were inadvertently deleted.

質問 # 23
Which process needs to be run before automatic failover can occur?
- A. node replication
- B. migration
- C. data deduplication
- D. tier to tape
正解：A
解説：
In IBM Spectrum Protect, automatic failover can occur when a primary node fails and a secondary node takes over its responsibilities. In order for this to work, the secondary node must be an exact copy of the primary node. This is achieved through node replication, which synchronizes the data and configuration between the primary and secondary nodes.
Node replication is a process that needs to be set up and run before automatic failover can occur. It involves creating a copy of the primary node and configuring it as a secondary node. The data and configuration are then synchronized between the two nodes, either continuously or on a schedule.
Once node replication is set up, the secondary node can take over the primary node's responsibilities in the event of a failure, without any interruption in service.
To summarize, node replication is the process that needs to be run before automatic failover can occur in IBM Spectrum Protect.
質問 # 24
Which function does the UPDATE NODE command allow?

- B. set if deduplication can occur for this node
- C. modify the node's dsm.opt file
- D. rename the node
正解：D
解説：
the UPDATE NODE command allows you to update node attributes, such as node name, password, policy domain, management class, deduplication settings, replication settings, and more1
質問 # 25
Which data is captured in a retention set?
- A. a subset of selected active and inactive data for a particular node or virtual machine
- B. a point-in-time collection of inactive client backup data for a set of nodes or virtual machines
- C. copies of all archived objects for a particular node or virtual machine
- D. a point-in-time snapshot of all the data in one or more file spaces that was active at the time of the snapshot
正解：B
解説：
According to the web search results, a retention set is a point-in-time collection of inactive client backup data for a set of nodes or virtual machines1. A retention set can be used to meet long-term data retention requirements without having to store multiple copies of the data on the server1.
質問 # 26
What happens by default if the journal engine service is installed and running when the incremental command is used for a backup?
- A. It backs up the file journal on an incremental basis.
- B. It updates the journal database with current data after a successful backup.
- C. It monitors the incremental backup process and collects all data that is eligible for the next journal-based full backup.
- D. It performs a journal-based backup on file systems that are being monitored by the journal engine service.
正解：D
解説：
The journal engine service monitors changes to specified files and directories and records information about the changes in a journal database. When a backup is performed on a file system that is being monitored by the journal engine service, IBM Spectrum Protect uses the information in the journal database to perform a journal-based backup. This allows IBM Spectrum Protect to quickly identify and back up only the files that have changed since the last backup, reducing the amount of data that needs to be backed up and speeding up the backup process.
According to IBM Spectrum Protect V8.1.9 documentation1, journal-based backup is an alternate method of backup that uses a change journal maintained by the IBM Spectrum Protect journal service process. To support journal-based backup, you must configure the journal engine service using the dsmcutil command or the client GUI setup wizard.
The incremental command backs up all new or changed data in the locations that you specify, unless you exclude them from backup services2. If the journal engine service is installed and running when the incremental command is used for a backup, it performs a journal-based backup on file systems that are being monitored by the journal engine service1.
質問 # 27
Which type of client backup can be restored without having access to the server?
- A. journal-based backup
- B. full backup
- C. retentionset
- D. backupset
正解：D
解説：
According to IBM documentation1, a backup set is a collection of your files that reside on the server, onto portable media created on a device using a format that is compatible with the client device. You can restore data from a backup set without having access to the server by using the dsmc restore backupset command1.

質問 # 28
What do dissimilar policies provide in IBM Spectrum Protect node replication between source and target servers?
- A. differing prioritization of client replication operations
- B. differing client node names
- C. differing retention of data
- D. differing administrative client owners
正解：C
解説：
In IBM Spectrum Protect node replication, dissimilar policies provide the ability to replicate client data between source and target servers with differing retention settings.
Dissimilar policies allow for more granular control over the retention settings of client data on the target server, which can be different from the retention settings on the source server. This means that the data can be kept for a longer or shorter period of time on the target server compared to the source server, based on the specific retention policies configured for the target server.
According to IBM documentation1, dissimilar policies provide the ability to use different management policies on the target replication server than on the source replication server. This means that you can have different retention periods, storage pools, or data types for replicated data on the target server. You can enable this feature by using the SET DISSIMILARPOLICIES command.

質問 # 29
Which command helps to protect the IBM Spectrum Protect server in case of a database failure?
- A. PREPARE
- B. PROTECT DB
- C. BACKUP DB
- D. DEFINE DBBACKUP
正解：C
解説：
The command that helps protect the IBM Spectrum Protect server in case of a database failure is "BACKUP DB." Backing up the Spectrum Protect database protects against data loss due to hardware failure [1], software problems, or other emergencies that might cause a total loss of the database. The BACKUP DB command creates a backup copy of the IBM Spectrum Protect database.
If a database failure occurs, the backup can be used to restore the database to a known state.
It is important to periodically perform backups of the IBM Spectrum Protect server database to ensure that the data is protected in the event of a failure [1]. Detailed instructions for performing backups can be found in the IBM Spectrum Protect V8.1.9 documentation.
