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 […]

Create a custom role In addition to built-in roles available in Azure, you might need to create a custom role to provide a set of permissions that are not available in any of the built-in roles. Custom roles can be created and assigned through the Azure portal, Azure PowerShell, Azure CLI, and REST API. This […]

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.

Understand how RBAC works Role-based access control (RBAC) facilitates the management of access to Azure resources by entities referred to as security principals, as well as controls what actions those entities can perform. In addition to determining who can do what, in Azure, access can be granted to users, groups, service principals, and managed identities through role assignments, […]
