Exam AZ-104 topic 6 question 11 discussion

NNY On January 15th you will have 9 backups as 0 day retention is defined as indefinite. [How many days to keep a backup before automatically deleting it. Set to 0 for indefinite retention.] https://docs.microsoft.com/en-us/cli/azure/webapp/config/backup?view=azure-cli-latest The DevOps / Web apps backup in the questions only includes the production slot. One cannot restore a test slot from a production slot backup. [If a slot is not specified, the API will create a backup for the production slot.] https://docs.microsoft.com/en-us/rest/api/appservice/web-apps/backup-slot January 6th backup will still be within the 30 days retention as of January 15th.

NNY 1. https://docs.microsoft.com/en-us/cli/azure/webapp/config/backup?view=azure-cli-latest --retention How many days to keep a backup before automatically deleting it. Set to 0 for indefinite retention. 2. didn't mention test slot backup at all 3. https://docs.microsoft.com/en-us/rest/api/appservice/web-apps/restore-slot we can restore a specific backup to another app (or deployment slot, if specified).

Answer YNY setting the daily backup retention period to 0 does not mean the backup is kept indefinitely. It means that the backup data is not retained for any specific number of days. However, if you enable the "Keep at least one backup" option, Azure ensures that at least one backup is always retained, regardless of the retention period setting

WRONG.. No No Yes

On January 15, 2021, App1 will have only one backup in storage = No ( Set to 0 for indefinite retention, ‘only one’ is wrong ) On February 6, 2021, you can access the backup of the App2 test slot from January 15, 2021 = No (backup for production slot) On January 15, 2021, you can restore the App2 production slot backup from January 6 to the App2 test slot = Yes

I took the exam on 9/13/24, I scored 858 and chose NNY. I studied only through ET for 3 weeks. All the questions were in ET except one which is probably new.

I argue that the first answer was yes because it said AT LEAST one copy. Then I saw a link in the comments that says this and I changed my answer to no. Explicitly says zero is indefinite. --retention How many days to keep a backup before automatically deleting it. Set to 0 for indefinite retention.

YNY Jan 15 have 1 backup test app have no back up App 2 have 30 days retention

No No Yes

- No - No - Yes

N N Y The Backup Configuration settings is for the production slots ONLY

As per my understanding, for box 2 - Y The test slot backup should be handled by Azure automatically and the default back strategy is "App backups happen automatically every hour."

Yes, Yes, and Yes. 1) On January 15, 2021, App1 will have only one backup in storage. App1 backs up every day and keeps at least one backup. However, the retention period for App1 is 0 days, meaning that any backup older than the most recent one is immediately deleted. Since App1 backs up every day, on January 15, App1 will indeed have only the backup from January 15 in storage. Answer: Yes 2) On February 6, 2021, you can access the backup of the App2 test slot from January 15, 2021. App2 backs up every day with a retention period of 30 days. Thus, the backup from January 15, 2021, would be retained until February 14, 2021. So, on February 6, you can still access the backup from January 15. Answer: Yes 3) On January 15, 2021, you can restore the backup of the App2 production slot from January 6, 2021. For App2, the backup from January 6, 2021, will be retained until February 5, 2021 (because of the 30-day retention period). So, you can indeed restore from this backup on January 15. Answer: Yes

NNY On January 15, 2021, App1 will have only one backup in storage: No. App1 is configured to backup every day starting from January 6, 2021, and retains each backup for 30 days. So on January 15, 2021, there will be 10 backups in storage (from January 6 to January 15). On February 6, 2021, you can access the backup of the App2 test slot from January 15, 2021: No. The backup configuration settings provided are for the production slots of App1 and App2. Unless the test slots have the same settings, we cannot assume that a backup from January 15, 2021 for the App2 test slot will be accessible on February 6, 2021. On January 15, 2021, you can restore the App2 production slot backup from January 6 to the App2 test slot: Yes. The backups for App2 are retained for 30 days. So a backup from January 6 would still be available on January 15 and could be restored to any slot including the test slot.

NYY Assumption - Basic tier is not used. Some inferences here. Since only production specs are specified, production backup is custom, test backup is automatic. 1)N - Set to 0 for indefinite retention. https://learn.microsoft.com/en-us/cli/azure/webapp/config/backup?view=azure-cli-latest#az-webapp-config-backup-update-optional-parameters 2)Y - Test backup is automatic. https://learn.microsoft.com/en-us/azure/app-service/manage-backup?tabs=portal#automatic-vs-custom-backups 3)Y - You can restore a backup by overwriting an existing app by restoring to a new app or slot. https://learn.microsoft.com/en-us/azure/app-service/manage-backup?tabs=portal#back-up--restore-vs-disaster-recovery In a nutshell, depending on how you interpret the question, the answers can be right or wrong. This is a good example of a miserable question.

Y N Y is correct!

Agree with NNY and with comments. 1: No 0 means retain all backups. ""Select your retention. Note that 0 means never delete backups." See; https://petri.com/backing-azure-app-service/ 2: No only production is backed up as per exam question. 3: Y: As far as I can find can be restored to any slot. See; See; https://learn.microsoft.com/en-us/azure/app-service/manage-backup?tabs=portal#back-up--restore-vs-disaster-recovery "Specify the restore destination in Choose a destination. To restore to a new app, select Create new under the App Service box. To restore to a new deployment slot, select Create new under the Deployment slot box. If you choose an existing slot, all existing data in its file system is erased and overwritten. The production slot has the same name as the app name."
