Question 16 of 30
16. Question
A financial institution is transmitting sensitive customer data over the internet and is considering using symmetric encryption to secure this data in transit. If they choose a key length of $128$ bits, how many possible keys will they have for encryption?
Correct
In the context of encryption in transit, it is crucial to understand how data is secured while being transmitted over a network.

Question 30 of 30
30. Question
A financial services company is implementing a Data Lifecycle Management strategy to optimize their data storage costs while ensuring compliance with regulatory requirements. They have classified their data into three categories: critical, sensitive, and archival. Which approach should they take to effectively manage the lifecycle of their data in Oracle Cloud Infrastructure?
Correct
Data Lifecycle Management (DLM) is a critical aspect of managing data effectively within cloud environments, particularly in Oracle Cloud Infrastructure (OCI). It involves the processes and policies that govern the creation, storage, usage, archiving, and deletion of data throughout its lifecycle. Understanding DLM is essential for ensuring data integrity, compliance with regulations, and optimizing storage costs. In practice, organizations must assess their data needs and classify data based on its importance and usage frequency. For instance, sensitive data may require stricter access controls and more frequent backups, while less critical data can be archived or deleted after a certain period. In the context of OCI, DLM can be implemented through various tools and services that automate these processes, ensuring that data is managed efficiently and in accordance with organizational policies. This includes setting up lifecycle policies that dictate when data should be moved to lower-cost storage options or when it should be deleted altogether. A nuanced understanding of DLM also involves recognizing the implications of data retention policies, compliance requirements, and the potential risks associated with data loss or unauthorized access. Therefore, a comprehensive grasp of DLM principles is vital for data professionals working within OCI.
