Which two considerations should a Citrix Engineer be aware of when creating application layers with Citrix App Layering? (Choose two.)

Which two statements are true regarding the traditional Workspace Environment Management (WEM) Administration console? (Choose two.)

Scenario: A Citrix Engineer needs to use Citrix App Layering to create layered images for use with a Citrix Virtual Apps and Desktops environment.
The environment currently has the following (MCS) Machine Creation Services-provisioned images.
-Windows 10 Virtual Delivery Agent (VDA) machines with App A, App B, and App C installed
-Windows 10 VDA machines with App A and App B installed
Application A is a common app that is needed by all users. Application B is a time reporting app needed by all individual contributors, and Application C is a managerial app needed by executives, but restricted from use by everyone else.
The environment uses Citrix Hypervisor to host all VDA machines.
To meet the minimum requirements while reducing administrative effort, the engineer would need layered image(s), using .

Scenario: A Citrix Engineer noticed that a Citrix Virtual Apps and Desktops environment lost connection to the SQL servers where the Citrix databases are running. Due to this, the Site has become unmanaged and first- time users CANNOT connect to their Citrix Virtual Apps & Desktops resources.
The setup was recently upgraded from Citrix Virtual Apps and Desktops 7.11 to Citrix Virtual Apps and Desktops 7.15 CU4.
What should the engineer do to minimize the impact of the SQL outage?

Scenario: A Citrix Engineer is managing a Citrix Virtual Apps and Desktops environment. The engineer has initiated a failover in the environment and wants to redirect the users to a different StoreFront server.
