The correct option is Negotiating service level agreements.

Negotiating service level agreements is primarily a customer responsibility because SLAs are contractual commitments that define availability performance remedies and support expectations. Providers typically publish standard SLAs but customers must review negotiate and accept terms that align with their business requirements and risk tolerance and they must document any special terms in their contract.

Cloud Identity and Access Management is offered by the provider as a managed capability and the customer configures and uses that service. This makes IAM a shared operational responsibility rather than a primarily contractual task for the customer.

Submitting support tickets to the provider is an operational action that customers perform when they need help. It does not change or establish the contractual guarantees and legal remedies that are set by SLA negotiations.

Participating in the shared responsibility model describes how duties are divided between provider and customer. It is a joint framework and not a single responsibility that falls only to the customer.
