Which feature is supported in all Oracle Database editions in Oracle Cloud Infrastructure?
All editions include Oracle Database Transparent Data Encryption, Machine Learning, and Spa-tial and Graph.
Standard Edition includes Oracle Database Standard Edition.
Enterprise Edition includes Oracle Database Enterprise Edition, Data Masking and Subset-ting Pack, Diagnostics and Tuning Packs, and Real Application Testing.
Enterprise Edition High Performance extends Enterprise Edition with the following options: Multitenant, Partitioning, Advanced Compression, Advanced Security, Label Security, Da-tabase Vault, OLAP, Database Lifecycle Management Pack and Cloud Management Pack for Oracle Database.
Enterprise Edition Extreme Performance extends High Performance with the following options: In-Memory Database, Active Data Guard, Real Application Clusters.
Data Guard is not supported Oracle Database Standard Edition.
What is the purpose of using Oracle Cloud Infrastructure (OCI) Identity and Access Management (IAM) policies in a cross-cloud connection between Microsoft Azure and OCI?
Controlling the Establishment of a Connection
With Oracle Cloud Infrastructure IAM policies, you can control:
Who in your organization has the authority to create a FastConnect virtual circuit.
Who can manage route tables, network security groups, and security lists.
Oracle and Microsoft have created a cross-cloud connection between Oracle Cloud Infrastructure and Microsoft Azure in certain regions. So, the option 'To control the location of the cross-cloud connection' has nothing to do with IAM policies and hence is INCORRECT.
The option 'To control the type of traffic allowed between the Azure VNet and the OCI VCN' is also INCORRECT as you use Security Lists/Network Security Group to filter traffic and not IAM policies.
IAM policies also have no role to play in determining the bandwidth of the connection.
What encryption protocol is used to secure data transmission in an OCI Site-to-Site VPN connec-tion?
Site-to-Site VPN provides a site-to-site IPSec connection between your on-premises network and your virtual cloud network (VCN). The IPSec protocol suite encrypts IP traffic before the packets are transferred from the source to the destination and decrypts the traffic when it arrives.
In the context of Oracle FastConnect, what are the two types of virtual circuits?
VIRTUAL CIRCUIT is an isolated network path that runs over one or more physical network connections to provide a single, logical connection between the edge of your existing network and Oracle Cloud Infrastructure. Private virtual circuits support private peering, and public virtual circuits support public peering.
A company has deployed an application in Oracle Cloud Infrastructure consisting of multiple web servers, database servers, and application servers. The company wants to restrict communication be-tween these components, allowing only the necessary traffic between them. Which OCI feature would be most suitable to achieve this objective?
Network security groups (NSGs) act as a virtual firewall for your compute instances .
An NSG consists of a set of ingress and egress security rules that apply only to a set of VNICs of your choice in a single VCN (for example: all the compute instances that act as web servers in the web tier of a multi-tier application in your VCN).
Hence, 'Use Network Security Groups to apply specific firewall rules for each component.' is the CORRECT answer.
In this question , you can straightaway reject 'Use Virtual Cloud Networks to create isolated net-works for each component.' and 'Use Route Tables to define custom routing policies between each component.' options.
NSG wins here due to the keywords 'restrict communication between these components' in the question. A network security group (NSG) provides a virtual firewall for a set of cloud re-sources that all have the same security posture.
