When describing the security features of Object Storage, which two of the following statements are correct?
B. Private DNS zones require internet connectivity for name resolution, while Public DNS zones can resolve names internally without internet access. C. Public DNS zones can be associated with multiple VCNs, whereas Private DNS zones are restricted to a single VCN. D. Public DNS zones are designed to resolve domain names globally on the internet, whereas Private DNS zones are intended for resolving domain names within specific Oracle Cloud Infrastructure networks. Explanation: Public DNS zones are designed to resolve domain names globally on the internet, whereas Private DNS zones are intended for resolving domain names within specific Oracle Cloud Infrastructure networks. -> Correct. This is the key difference between Public and Private DNS zones. Public DNS zones facilitate domain name resolution on the global internet, making them accessible from anywhere, while Private DNS zones are used within OCI for internal network resolution, enhancing security and internal network management. Private DNS zones require internet connectivity for name resolution, while Public DNS zones can resolve names internally without internet access. -> Incorrect. The primary function of Private DNS zones is to resolve domain names within a VCN without requiring internet connectivity. Public DNS zones are accessible over the internet for global resolution. Public DNS zones support dynamic DNS updates, whereas Private DNS zones do not. -> Incorrect. The support for dynamic DNS updates is not a differentiating factor between Public and Private DNS zones in OCI. Features and capabilities regarding DNS updates are determined by the DNS service's overall functionality and policies, not by the zone type. Public DNS zones can be associated with multiple VCNs, whereas Private DNS zones are restricted to a single VCN. -> Incorrect. Private DNS zones are indeed intended for use within specific VCNs, but the distinction is not about the number of VCNs they can be associated with. Rather, it's about the scope of access —internal versus global. Public DNS zones do not "associate" with VCNs as they are used for global resolution. A financial services company is migrating its highly sensitive operations to Oracle Cloud Infrastructure (OCI). The company requires a robust mechanism to manage encryption keys and secrets that are used to encrypt database passwords, API keys, and other sensitive data. Which OCI service should the company configure to ensure the secure storage, management, and auditing of these cryptographic keys and secrets?
D. Implement OCI Vault to securely manage, store, and rotate encryption keys and secrets, ensuring compliance with industry standards and regulations. Explanation: Implement OCI Vault to securely manage, store, and rotate encryption keys and secrets, ensuring compliance with industry standards and regulations. -> Correct. OCI Vault is specifically designed for the secure management of encryption keys and secrets. It supports key management and secrets management capabilities, allowing organizations to store, rotate, and manage access to cryptographic keys and secrets securely. This helps in ensuring that sensitive information like database passwords and API keys are encrypted and managed according to best practices and compliance standards. Use OCI Object Storage with server -side encryption for managing encryption keys and secrets. -> Incorrect. While OCI Object Storage provides server -side encryption for data at rest, it is primarily a storage solution and not specifically designed for the detailed management or rotation of encryption keys and secrets. It cannot provide the same level of control and auditing capabilities for keys and secrets as OCI Vault. Configure OCI Identity and Access Management (IAM) to handle encryption keys and secret management. -> Incorrect. OCI IAM is crucial for managing access and identities within OCI but does not offer dedicated features for the secure storage, rotation, and management of encryption keys and secrets. IAM focuses on user and permission management rather than on cryptographic key and secrets management. Activate OCI Cloud Guard to manage and audit the use of encryption keys and secrets. -> Incorrect. OCI Cloud Guard is a security posture management service that helps identify and remediate security threats across OCI resources. However, it is not designed for the management of encryption keys and secrets. Cloud Guard focuses on security monitoring and compliance, rather than cryptographic management. You are tasked with ensuring high availability and fault tolerance for a critical database running on Oracle Cloud Infrastructure (OCI). The database supports a highly available application that cannot tolerate more than 2 minutes of downtime per month. Which OCI feature should you implement to meet this requirement?
multiple instances of Oracle Database to run on multiple servers. This setup provides high availability, scalability, and redundancy for critical applications, ensuring minimal downtime and meeting the stringent uptime requirement. Autonomous Data Warehouse -> Incorrect. Autonomous Data Warehouse is optimized for analytical processing and would not be the best fit for providing the high availability and fault tolerance required by a critical transactional database application. Block Volume Cloning -> Incorrect. Block Volume Cloning allows you to create a copy of a block volume without interrupting the source volume. While useful for backup and scaling, it does not provide the immediate fault tolerance or high availability needed for the application. Virtual Cloud Network (VCN) Peering -> Incorrect. Virtual Cloud Network (VCN) Peering allows connectivity between two VCNs, facilitating communication across different cloud environments or regions. However, it does not address the availability or fault tolerance of database services directly. In the context of configuring cross -region replication for Oracle Cloud Infrastructure (OCI) Object Storage, which statement accurately describes a best practice for ensuring data integrity and availability across regions?
backups are essential for data durability within a region but are separate from cross -region replication, which requires explicit configuration to replicate data across regions. You are tasked with designing a storage solution for a company that needs to store large volumes of unstructured data. The data must be accessible over the internet, highly available, and securely stored. Which of the following approaches would best meet these requirements using OCI Object Storage?
traffic and other applications requiring data integrity. HTTP (Hypertext Transfer Protocol): Frequently used for web traffic, it is an application -layer protocol built on top of TCP and enables communication between web browsers and servers. The combination of these protocols allows the OCI Network Load Balancer to manage diverse workloads, including web services and real -time applications. For reference: OCI Load Balancer Documentation Which policy would you write to provide admin access to all three of your existing admin groups for a shared Test compartment?
