Exam ISO-IEC-27001-Lead-Auditor Topic 5 Question 242 Discussion

Scenario 9: UpNet, a networking company, has been certified against ISO/IEC 27001. It provides network security, virtualization, cloud computing, network hardware, network management software, and networking technologies.
The company's recognition has increased drastically since gaining ISO/IEC 27001 certification. The certification confirmed the maturity of UpNefs operations and its compliance with a widely recognized and accepted standard.
But not everything ended after the certification. UpNet continually reviewed and enhanced its security controls and the overall effectiveness and efficiency of the ISMS by conducting internal audits. The top management was not willing to employ a full-time team of internal auditors, so they decided to outsource the internal audit function. This form of internal audits ensured independence, objectivity, and that they had an advisory role about the continual improvement of the ISMS.
Not long after the initial certification audit, the company created a new department specialized in data and storage products. They offered routers and switches optimized for data centers and software-based networking devices, such as network virtualization and network security appliances. This caused changes to the operations of the other departments already covered in the ISMS certification scope.
Therefore. UpNet initiated a risk assessment process and an internal audit. Following the internal audit result, the company confirmed the effectiveness and efficiency of the existing and new processes and controls.
The top management decided to include the new department in the certification scope since it complies with ISO/IEC 27001 requirements. UpNet announced that it is ISO/IEC 27001 certified and the certification scope encompasses the whole company.
One year after the initial certification audit, the certification body conducted another audit of UpNefs ISMS.
This audit aimed to determine the UpNefs ISMS fulfillment of specified ISO/IEC 27001 requirements and ensure that the ISMS is being continually improved. The audit team confirmed that the certified ISMS continues to fulfill the requirements of the standard. Nonetheless, the new department caused a significant impact on governing the management system. Moreover, the certification body was not informed about any changes. Thus, the UpNefs certification was suspended.
Based on the scenario above, answer the following question:
UpNet ensured independence, objectivity, and advisory activities from the internal audit. Is this action acceptable?
