C. Synthetic backups maintain a catalog of files and directories for each backup image, while TIR creates a full backup image from existing backups.
D. Synthetic backups restore files from the most recent backup image, while TIR creates a full backup image from existing backups.

정답：A

질문 # 241
Which command should an administrator use to generate a list of all files backed up on a client for a specific backup job?

A. bpdbjobs
B. bpimage
C. bpimagelist
D. bplist

정답：D

질문 # 242
What is the name of the feature that lets you detect and alert on abnormal backup activity in NetBackup?

A. Anomaly Detection
B. Backup Analytics
C. Backup Monitor
D. Backup Audit

정답：A

질문 # 243
How are install packages for a deployment policy execution obtained?

A. They are downloaded from the Veritas support site when the policy is launched.
B. They must be manually added to the primary server repository before the policy can be launched.
C. They must be manually copied to the clients before the policy can be launched.
D. They must be manually added to a repository that is external to the NetBackup environment prior to launching the policy.

정답：B

설명：
The correct answer is A. NetBackup deployment policies use VxUpdate, and VxUpdate relies on the NetBackup package repository located on the primary server. Cohesity documentation states that "VxUpdate uses a repository that resides on the primary server" and that the repository contains the packages that can be deployed to media servers and clients. It also explains that the packages referenced by deployment policies are verified and installed into that repository before use. In the deployment policy workflow, the administrator selects a package from the policy's Package drop-down list; therefore, the package must already exist in the repository before the policy can run successfully. Cohesity explicitly notes that packages must be added to the VxUpdate repository before creating a working deployment policy, and policies without packages in the repository fail when run. Packages are not manually copied to every client, are not maintained in an external repository, and are not downloaded automatically from support at launch time. The administrator downloads or obtains the appropriate signed VxUpdate package, then adds it using the web UI or nbrepo -a. References
/topics: Deployment Management, VxUpdate, Package Repository, and nbrepo repository management.

질문 # 244
Which command should an administrator use to view the expiry date of the local host-ID based certificate?

A. bpclntcmd -listEnrollmentStatus
B. nbcertcmd -hostSelfCheck
C. nbcertcmd -listCertDetails
D. nbcertcmd -listCACertDetails

정답：C

설명：
The correct command is nbcertcmd -listCertDetails. Cohesity NetBackup documentation states that host ID- based certificate details can be viewed with the NetBackup web UI, the nbcertcmd command, or NetBackup APIs. In the command procedure, Cohesity specifically instructs administrators to run nbcertcmd - listCertDetails on the NetBackup host to view host IDs and associated certificate details for that host. The NetBackup Commands Reference also confirms that nbcertcmd is the utility used to request and manage host ID-based security certificates on NetBackup hosts, including primary servers, media servers, and clients. It lists -listCertDetails as the operation that displays certificate details for security certificates deployed on the NetBackup host.
Option A is incorrect because -listCACertDetails displays trusted CA certificate details, not the local host-ID certificate expiry. Option B is invalid in this context because enrollment status is not viewed with bpclntcmd.
Option C, -hostSelfCheck, checks whether the host certificate is revoked, not its expiration date. Reference topics: NetBackup Security and Encryption Guide, Viewing host ID-based certificate details, and nbcertcmd command reference.
