You have created a virtual cloud network (VCN) with three private subnets. Two of the subnets contain application servers and the third subnet contains a DB System. The application requires a shared file system so you have provisioned one using the file storage service (FSS). You also created the corresponding mount target in one of the application subnets. The VCN security lists are properly configured so that both application servers and the DB System can access the file system. The security team determines that the DB System should have read-only access to the file system. What change would you make to satisfy this requirement?
A. Create an NFS export option that allows READ_ONLY access where the source is the CIDR range of the DB System subnet.
B. Connect via SSH to one of the application servers where the file system has been mounted. Use the Unix command chmod to change permissions on the file system directory, allowing the database user read only access.
C. Modify the security list associated with the subnet where the mount target resides. Change the ingress rules corresponding to the DB System subnet to be stateless.
D. Create an instance principal for the DB System. Write an Identity and Access Management (IAM) policy that allows the instance principal read-only access to the file storage service.
Which two choices are true for Autonomous Data Warehouse (ADW)? (Choose two.)
A. Billing stops only when the ADW is terminated
B. Billing stops for both CPU usage and storage usage when ADW is stopped
C. Billing for compute stops when ADW is stopped
D. Billing for storage continues when ADW is stopped
You have created a public subnet and an internet gateway in your virtual cloud network (VCN). The public
subnet has an associated route table and security list. However, after creating several compute instances
in the public subnet, none can reach the Internet.
Which two are possible reasons for the connectivity issue? (Choose two.)
A. The route table has no default route for routing traffic to the internet gateway
B. There is no stateful egress rule in the security list associated with the public subnet
C. There is no dynamic routing gateway (DRG) associated with the VCN
D. There is no stateful ingress rule in the security list associated with the public subnet
What is true about data guard set up with fast-start failover (FSFO) in Oracle Cloud Infrastructure (OCI)?
A. The best practice for high availability and durability is to run the primary, standby, and observer in separate availability domains (ADs).
B. When you configure data guard using OCI console, the default mode is set to maxprotection.
C. You cannot create the standby DB system in a different AD from the primary DB system.
D. You cannot use database command line interface (CLI) to set up data guard with FSFO.
Your company has decided to move a few applications to Oracle Cloud Infrastructure (OCI) and you have been asked to design a cloud-based disaster recovery (DR) solution. One of the requirements is to deploy the DR resources at least 300 miles from the home OCI region and minimize the network latency. What will be the recommended deployment?
A. Deploy production and DR applications in the same VCN. Create production subnets in one AD, and DR subnets in another AD.
B. Deploy production and DR applications in two separate VCNs in different availability domains (ADs) within your home region, and then use a VCN remote peering connection for connectivity.
C. Deploy production and DR applications in two separate VCNs, each in different regions. Connect them using a VCN remote peering connection.
D. Deploy production and DR applications in two separate virtual cloud networks (VCNs), each in different regions, and then use VCN local peering gateways for connectivity.
Which statement is true about Oracle Cloud Infrastructure FastConnect?
A. For private peering, FastConnect extends your existing infrastructure to allow you to consume object storage from your on-premises data center
B. For private peering, FastConnect extends your existing infrastructure to a virtual cloud network C. The FastConnect provider network offers only 1 Gbps port connection speed increments
D. For public peering, a dynamic routing gateway must be configured and attached to the virtual cloud network (VCN)
As the Cloud Architect for your company, you have been tasked with designing a high performance (HPC)
cluster in Oracle Cloud Infrastructure (OCI). The following requirements have been defined:
The cluster must be a minimum of three nodes, but may increase to six nodes when demand requires.
The cluster must be resilient to any potential infrastructure failures.
To minimize latency, all nodes must be deployed within the same availability domain (AD).
Adding or replacing nodes within the cluster should take no more than 30 minutes.
Which two steps should be performed to satisfy these requirements in OCI? (Choose two.)
A. Deploy the cluster in a single AD with a shared file system that leverages the file storage service (FSS). Deploy a standby cluster in another AD and configure it to use the same shared file system.
B. Deploy the cluster in a single AD. Place each of the nodes in one of the three different fault domains in that AD.
C. Create a backup of your HPC node compute instance boot volume. Launch new compute instances directly from the backup reduce provisioning time.
D. Create a custom image of your HPC node compute instance. Launch new compute instances using this image to reduce provisioning time.
E. Deploy the cluster in a single AD. Place each of the nodes in a different virtual cloud network (VCN) subnet.
You are designing a high bandwidth, redundant connection between your data center and Oracle Cloud
Infrastructure (OCI). While researching for OCI FastConnect locations, you notice that you are co-located
with Oracle at one of the Oracle FastConnect locations in the Ashburn region.
What is the recommended design in this scenario?
A. Create a cross-connect group and have two or more cross-connects in that group. Create an IPsec VPN connection on this group.
B. Setup two IPsec connections between your data center and OCI Ashburn region. Create a OCI load balancer to distribute the traffic across the two connections.
C. Create a cross-connect group and have at least two or more cross-connects in that group. Create at least two or more virtual circuits in the group.
D. Create a cross-connect group and have at least one cross-connect in that group. Create at least one virtual circuit in the group.
You are about to upload log file (5 TiB size) to Oracle Cloud Infrastructure object storage and have
decided to use multipart upload capability for a more efficient and resilient upload.
Which two statements are true about multipart upload? (Choose two.)
A. Individual object parts can be as small as 10 MiB or as large as 50 GiB
B. While a multipart upload is still active, you cannot add parts even if the total number of parts is less than 10,000
C. The maximum size for an uploaded object is 10 TiB
D. You do not have to commit the upload after you have uploaded all the object parts
You are running a mission-critical database in Oracle Cloud Infrastructure (OCI). You take regular backups
of your DB system to OCI object storage. Recently, you notice a failed database backup status in the
console.
What two steps can you take to determine the cause of the backup failure? (Choose two.)
A. Ensure the database archiving mode is set to NOARCHIVELOG
B. Ensure that your database host can connect to the OCI object storage
C. Restart the dcsagent program if it has a status of stop or waiting
D. Make sure that the database is not active and running while backup is in progress
