Oracle has integrated the FastConnect service with a geographically diverse set of IP, VPN, and Ethernet network providers and cloud exchanges to make it easy for you to establish a connection to Oracle Cloud services.
FastConnect: Colocation with Oracle:
If you have purchased colocation space from a data center provider, you can use Oracle FastCon-nect to establish connectivity from your network equipment in that colocation facility to your Oracle Cloud services provisioned at this location. Oracle will provide you a letter of authorization (LOA) that the data center provider will need in order to establish a direct cross-connect into Oracle's FastConnect edge devices provider will need in order to establish a direct cross
NEW QUESTION # 22
What should you do to prepare your Oracle Cloud Infrastructure (OCI) Virtual Cloud Network (VCN) for potential security risks when connected to a Microsoft Azure VNet?
- A. Remove all OCI security rules.
- B. Allow all traffic from the Azure VNet without restrictions.
- C. Limit all inbound and outbound traffic from the Azure VNet to expected and well-defined traffic.
- D. Disable the connection between Azure VNet and OCI VCN.
Answer: C
Explanation:
Controlling Traffic Flow Over the Connection
Even if a connection has been established between your VCN and VNet, you can control the packet flow over the connection with route tables in your VCN. For example, you can restrict traf-fic to only specific subnets in the VNet.
Controlling the Specific Types of Traffic Allowed
It's important that you ensure that all outbound and inbound traffic with the VNet is intended or expected and well defined. Implement Azure network security group and Oracle security rules that explicitly state the types of traffic one cloud can send to the other and accept from the other.
NEW QUESTION # 23
A company has deployed a multi-tier application in Oracle Cloud Infrastructure (OCI), with web servers in a public subnet and database servers in a private subnet. The database servers need to ac-cess data from OCI Object Storage, and the company wants to ensure that this communication is secure and not exposed to the public internet. Which OCI feature should be used to achieve this objective?
- A. Use a NAT Gateway to enable private access to Object Storage.
- B. Use a VPN Gateway to create an encrypted tunnel to Object Storage.
- C. Use a Local Peering Gateway to peer with the Object Storage subnet.
- D. Use a Service Gateway to establish a secure connection to Object Storage.
Answer: D
Explanation:
A service gateway lets your virtual cloud network (VCN) privately access specific Oracle services without exposing the data to the public internet. No internet gateway or NAT gateway is required to reach those specific services.
The resources in the VCN can be in a private subnet and use only private IP addresses. The traffic from the VCN to the Oracle service travels over the Oracle network fabric and never traverses the internet.

NEW QUESTION # 30
What does the term "multicloud" mean and how can it help organizations manage their IT infra-structure?
- A. The integration of on-premises infrastructure with cloud services for a hybrid cloud approach
- B. The use of multiple cloud services from a single provider for redundancy and high availability
- C. The deployment of a single cloud service across multiple regions and data centers for better performance
- D. The use of cloud services from multiple providers to leverage the best features and ser-vices of each
Answer: D
Explanation:
The keyword here is multiple providers. Multicloud is a cloud computing strategy that uses the best services from more than one cloud provider to deploy a solution.
The use of multiple cloud services from a single provider for redundancy and high availability is INCORRECT as it talks about single provider.
The deployment of a single cloud service across multiple regions and data centers for better perfor-mance is also INCORRECT as there is no mention of multiple cloud service providers. Rather it talks about single cloud service across multiple regions.
The use of multiple cloud services from a single provider for redundancy and high availability is al-so INCORRECT as it also talks about single provider.
Hence the correct answer is The use of cloud services from multiple providers to leverage the best features and services of each.
NEW QUESTION # 31
A consulting company that employs Oracle Cloud Infrastructure (OCI) architects has successfully completed resource migration from Microsoft Azure to OCI, and no longer requires the Oracle FastConnect circuit to Azure. The project manager has asked you to delete all resources involved in this cross-cloud connectivity. From the Azure side, you delete the Resource Group. After a while, you notice that all Azure resources have been deleted, except for the Azure ExpressRoute circuit.
What could be a potential reason for this issue?
- A. You need to remove all routes that point to the cross-cloud connection on both OCI and Azure before you can delete the circuit.
- B. Your bill from the OCI side needs to be paid in full before you can remove the Azure ExpressRoute circuit.
- C. You need to first delete the Oracle FastConnect circuit for the ExpressRoute circuit to be decommissioned, and then you can delete the ExpressRoute virtual circuit.
- D. You need to remove the Azure ExpressRoute Partner Service Key from the Oracle FastConnect circuit, and then you can delete the ExpressRoute virtual circuit.
Answer: C
Explanation:
To delete the interconnect, perform these steps in the order given. Failure to do so results in a failed state ExpressRoute circuit.
1. Delete the ExpressRoute connection. Delete the connection by selecting the Delete icon on the page for your connection.
2. Delete the Oracle FastConnect circuit from the Oracle Cloud Console.
3. Once the Oracle FastConnect circuit has been deleted, you can delete the Azure Ex-pressRoute circuit.
Hence "You need to first delete the Oracle FastConnect circuit for the ExpressRoute circuit to be decommissioned, and then you can delete the ExpressRoute virtual circuit." is the CORRECT AN-SWER.
NEW QUESTION # 32
To achieve high availability in a 2-node RAC DB System in Oracle Cloud Infrastructure, what would you use to distribute your nodes to provide database instance fault isolation?
- A. Availability Domains
- B. Fault Domains
- C. Local region
