質問 # 18
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. SSL encrypted communication
- C. server-side encryption
- 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.
質問 # 19
Which information might indicate that a cyber attack has occurred for a particular node?
- A. node is marked inactive for next backup schedule
- B. lock the filespace for the specific node
- C. increase in data ingest total for that node
- D. deduplication ratio increases for that node
正解：C
解説：
According to the IBM Documentation1, one possible indication that a cyber attack has occurred for a particular node is an increase in data ingest total for that node. This means that the amount of data that is transferred from the client node to the server during backup operations has increased significantly, which could be a sign of ransomware or other malicious software modifying or encrypting files on the node.
質問 # 20
Which command helps to protect the IBM Spectrum Protect server in case of a database failure?
- A. BACKUP DB
- B. PROTECT DB
- C. DEFINE DBBACKUP
- D. PREPARE
正解：A
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.

質問 # 31
What happens by default if the journal engine service is installed and running when the incremental command is used for a backup?
- A. It monitors the incremental backup process and collects all data that is eligible for the next journal-based full backup.
- B. It updates the journal database with current data after a successful backup.
- C. It backs up the file journal on an incremental basis.
- 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.
