You are planning the migration waves for a complex enterprise environment. You have identified a 3-tier application: Web servers, App servers, and a Database server. The database server is also accessed by a separate reporting application. To ensure minimal disruption and optimal performance post-migration, which TWO principles should guide your wave planning? (Select TWO)

Answer options:

Migrate the Web, App, and Database servers for the 3-tier app in the same wave.

Migrate all databases first, then migrate all web servers in a later wave.

Include the reporting application in the same wave as the database server.

Migrate servers based strictly on their operating system (e.g., all Windows first, then Linux).

Migrate the largest servers first to test network bandwidth.

How to approach this question

Apply the principle of migrating highly dependent systems together.

Full Answer

A,C

Migration waves must be planned based on application dependencies. Tightly coupled systems (like the tiers of an app, or an app and its database) must be migrated in the same wave to avoid the latency of cross-premises communication.

Common mistakes

Planning waves by server type (all DBs, then all Web) rather than by application dependency.
