Manage multiple directories Each Entra ID tenant (or directory) is managed as an independent resource. There is no parent- child relation between directories, although users from one directory can be invited to another directory through Entra External Identities features.

IP also defines how to group addresses together, just like the postal system groups addresses based on postal codes (like ZIP codes in the […]

Interpret access assignments To manage access (role) assignments, you can use the Azure portal, the Azure CLI, Azure PowerShell, Azure SDKs, or the Resource Manager REST APIs. The following section describes how to manage role assignments using the Azure portal. In the Azure portal, the Access Control (IAM) blade is used to manage access to resources, and […]

Note Use the ip ospf mtu-ignore command for OSPFv2 or ipv6 ospf mtu-ignore command for OSPFv3 to disable MTU mismatch detection on an interface. By default, OSPF checks whether neighbors use the same MTU on a common interface. If the receiving MTU is higher than the IP MTU configured on the incoming interface, OSPF does […]

For example, the process of creating a bank account in a connected system […]

Understand how RBAC works The specific permissions that are applied to a resource with RBAC are defined in a role definition. A role definition contains the list of permissions—or declared permissions—and those permissions define what actions can or cannot be performed against a type of resource, such as read, write, or delete. Role definitions, or roles, can be […]

Assigning Values Compilation errors from assignment operators are often overlooked on the exam, in part because of how subtle these errors can be. To be successful with the assignment operators, you should be fluent in understanding how the compiler handles numeric promotion and when casting is required.
