Litware is evaluating whether to add high availability after the migration? What should you recommend to meet the technical requirements?
Correct Answer: A
Explanation:
To meet Litware’s high-availability requirements after migration, you should recommend SAP HANA system replication combined with Azure Availability Sets. SAP HANA system replication provides real-time data replication from a primary HANA database to a secondary instance, ensuring minimal data loss and rapid failover in the event of a failure. Azure Availability Sets further enhance availability by distributing virtual machines across different fault domains and update domains, reducing the risk of downtime caused by hardware failures or planned maintenance. Option B only provides restart capabilities and does not offer true high availability or protection against infrastructure failures. Option C, Azure Site Recovery, is primarily a disaster recovery solution designed for site-level outages rather than high availability within the production environment. Therefore, SAP HANA system replication with Azure Availability Sets is the most appropriate solution for meeting the technical requirements.
Question 2
You are evaluating which migration method Litware can implement based on the current
environment and the business goals. Which migration method will cause the least amount of downtime?
Correct Answer: A
Explanation:
The SAP Database Migration Option (DMO) with System Move option of SUM, used as part of the migration allows customer the options to perform the migration in a single step, from source system on-premises, or to the target system residing in Microsoft Azure, minimizing overall downtime.

Question 3
Correct Answer: A
Explanation:
In a Hybrid-IT scenario, Active Directory from on-premises can be extended to serve as the authentication mechanism through an Azure deployed domain controller (as well as potentially using the integrated DNS). It is important to distinguish between traditional Active Directory Servers and Microsoft Azure Active Directory that provides only a subset of the traditional on-premises AD offering. This subset include Identity and Access Management, but does not have the full AD schema or services that many 3rd party application take advantage of. While Azure Active Directory IS a requirement to establish authentication for the Azure virtual machines in use, and it can synchronize users with customers’ on-premises AD, the two are explicitly different and customers will likely continue to require full Active Directory servers deployed in Microsoft Azure.
