Question: Which of the following Basic CM IRP operations can be cancelled by invoking `cancelOperation`, as per the Configuration Management (CM) Integration Reference Point (IRP) protocol?
Option 1: `getMOAttributes` and `getContainment`
Option 2: `setMOAttributes` and `createContainment`
Option 3: `deleteMO` and `updateContainment`
Option 4: `notifyAlarm` and `acknowledgeAlarm`
Explanation: In the context of Telecommunication Management's Configuration Management (CM) and its Basic CM Integration Reference Point (IRP), the `cancelOperation` is specifically designed to halt ongoing operations. This cancellation capability is presently limited to two types of operations: retrieving attributes of a Managed Object (`getMOAttributes`) and determining containment relationships (`getContainment`). This targeted approach ensures that IRPManager can efficiently manage and interrupt specific, potentially resource-intensive or long-running queries, without broadly impacting all operation types.
