SK0-005 Exam Results

Scenario: Migrating a stand-alone application storing PII to the cloud.

Data to Encrypt: Data at rest (Option B) should be encrypted:

Data in transit (Option A) and backups (Option C) are also important but not the primary concern here.

Data archives (Option D) may or may not contain sensitive data.

Archive is a method of storing historical data that is not frequently accessed or modified. Archive can reduce the amount of data that needs to be backed up and save bandwidth and storage space. Differential is a method of backing up only the data that has changed since the last full backup. Differential can also save bandwidth and storage space, as well as speed up the backup process.

A DNS entry is a record that maps a domain name to an IP address. If the DNS entry for the new application is incorrect, users will not be able to resolve the domain name to the correct IP address and port number. This will prevent them from accessing the application, even if the firewall rules allow port 8443. To fix this issue, the server administrator should verify and update the DNS entry for the new application.

The most likely cause of the issue is that the server has not been joined to the domain. A domain is a logical group of computers and devices that share a common directory service and security policy. A domain controller is a server that manages the domain and authenticates users and computers that want to access domain resources. To log on with domain credentials, a server must be joined to the domain and registered in the directory service. If a server has not been joined to the domain, it will not be recognized or authorized by the domain controller.
