Original Sentences:

1. engine_version – (Optional) Version number of the cache engine to be used. If not set, defaults to the latest version. See Describe Cache Engine Versions in the AWS Documentation for supported versions. When engine is redis and the version is 7 or higher, the major and minor version should be set, e.g., 7.2. When the version is 6, the major and minor version can be set, e.g., 6.2, or the minor version can be unspecified which will use the latest version at creation time, e.g., 6.x. Otherwise, specify the full version desired, e.g., 5.0.6. The actual engine version used is returned in the attribute engine_version_actual, see Attribute Reference below.
2. security_group_ids – (Optional, VPC only) One or more VPC security groups associated with the cache cluster
3. subnet_group_name – (Optional, VPC only) Name of the subnet group to be used for the cache cluster. Changing this value will re-create the resource.

Issues in the Original Sentence:

1. Clarity: Including "Cannot be provided with replication_group_id" ensures clarity for users regarding limitations in argument reference combinations.

2. Error Prevention: It helps prevent errors by specifying what cannot be used together after applying the configuration.

3. Operational Guidance: Offers guidance on resource behavior and promotes best practices in usage.

Cannot be provided with replication_group_id.
2. security_group_ids – (Optional, VPC only) One or more VPC security groups associated with the cache cluster. Cannot be provided with replication_group_id.
3. subnet_group_name – (Optional, VPC only) Name of the subnet group to be used for the cache cluster. Changing this value will re-create the resource. Cannot be provided with replication_group_id.

The inclusion of "Cannot be provided with replication_group_id" is beneficial as it prevents configuration mistakes, enhances user understanding, and encourages adherence to best practices.
