Question 3

Explanation

"Note: Avoid the CI class downgrade and CI class switch operations as those can lead to data loss. When automatic CI reclassification is enabled (which is by default), the identification process can result in some automatic reclassifications which lead to data loss."

During CI reclassification, the two operations that are more likely to lead to data loss are:

Switching: Reclassifying a CI to a class in a different branch of the class hierarchy, which has a different set of attributes than the current class. When switching, attributes that are unique to the current class and not defined in the newly assigned class are lost. This can result in data loss if there are specific attributes associated with the current class that are not present in the new class.

Downgrading: Reclassifying a CI to a class that is higher in the class hierarchy, where the newly assigned class is a parent of the current class. During the downgrade, attributes that are unique to the current class and not defined in the newly reclassified class are lost. If the current class has attributes that are not present in the higher-level parent class, those attributes and their respective values will be lost during the reclassification.

Other options:

Upgrading, on the other hand, involves reclassifying a CI to a class that is lower in the class hierarchy, where the newly assigned class is a derived child of the current class and has additional attributes. It does not typically lead to data loss because the new class includes the attributes of the current class and adds additional attributes.

Identifying is not an operation related to CI reclassification. It refers to the process of uniquely identifying CIs during the discovery process and does not directly impact the reclassification of CIs.
