NEW QUESTION # 50
Which statement is true about Data Guard Implementation in DB systems?
- A. You cannot manage the database as sys/sysdba.
- B. You can define the backup window and set custom backup retention period for the automatic database backup schedule.
- C. Both DB systems must be in the same compartment, and they must be the same shape
- D. You cannot manage Oracle database initialization parameters at a global level.
Answer: C
Explanation:
An Oracle Data Guard implementation requires two DB systems, one containing the primary database and one containing the standby database. When you enable Oracle Data Guard for a virtual machine DB system database, a new DB system with the standby database is created and associated with the primary database. For a bare metal DB system, the DB system with the database that you want to use as the standby must already exist before you enable Oracle Data Guard.
Requirement details are as follows:
- Both DB systems must be in the same compartment.
- The DB systems must be the same shape type (for example, if the shape of the primary database is a virtual machine, then the shape of the standby database can be any other virtual machine shape).
- If your primary and standby databases are in different regions, then you must peer the virtual cloud networks (VCNs) for each database. See Remote VCN Peering (Across Regions).
- Configure the security list ingress and egress rules for the subnets of both DB systems in the Oracle Data Guard association to enable TCP traffic to move between the applicable ports. Ensure that the rules you create are stateful (the default).
NEW QUESTION # 51
Your application consists of three Oracle Cloud Infrastructure compute instances running behind a public load balancer. You have configured the load balancer to perform health checks on these instances, but one of the three instances fails to pass the configured health check. Which of the following action will the load balancer perform?
- A. Remove the instance that failed the health check from the backend set
- B. Terminate the instance that failed health check
- C. Stop sending traffic to the instance that failed health check
- D. Stop the instances that failed health check
Answer: C
Explanation:
Explanation
health check A test to confirm the availability of backend servers. A health check can be a request or a connection attempt. Based on a time interval you specify, the load balancer applies the health check policy to continuously monitor backend servers. Ifa server fails the health check, the load balancer takes the server temporarily out of rotation. If the server subsequently passes the health check, the load balancer returns it to the rotation.
You configure your health check policy when you create a backend set. You can configure TCP-level or HTTP-level health checks for your backend servers.
- TCP-level health checks attempt to make a TCP connection with the backend servers and validate the response based on the connection status.
- HTTP-level health checks send requests to the backend servers at a specific URI and validate the response based on the status code or entity data (body) returned.
The service provides application-specific health check capabilities to help you increase availability and reduceyour application maintenance window.

- D. An Archive Object Storage tier bucket can be upgraded to the Standard Object Storage tier.
Answer: C
NEW QUESTION # 53
You have an application deployed in Oracle Cloud Infrastructure running only in the Phoenix region. You were asked to create a disaster recovery (DR) plan that will protect against the loss of critical dat a. The DR site must be at least 500 miles from your primary site and data transfer between the two sites must not traverse the public Internet.
Which is the recommended disaster recovery plan?
- A. Create a DR environment in Ashburn. Associate a DRG with the VCN in each region and create a remote peering connection between the two VCNs.
- B. Create a DR environment in Ashburn and provision a FastConnect virtual circuit using DRG between the regions.
- C. Create a DR environment in Ashburn. Associate a dynamic routing gateway (DRG) with the VCN in each region and configure an IPsec VPN connection between the two regions.
- D. Create a new virtual cloud network (VCN) in the Phoenix region and create a subnet in one availability domain (AD) that is not currently being used by your production systems. Establish VCN peering between the production and DR sites.
Answer: A
Explanation:
Remote VCN peering is the process of connecting two VCNs in different regions (but the same tenancy ). The peering allows the VCNs' resources to communicate using private IP addresses without routing the traffic over the internet or through your on-premises network. Without peering, a given VCN would need an internet gateway and public IP addresses for the instances that need to communicate with another VCN in a different region.
At a high level, the Networking service components required for a remote peering include:
- Two VCNs with non-overlapping CIDRs, in different regions that support remote peering. The VCNs must be in the same tenancy.
- A dynamic routing gateway (DRG) attached to each VCN in the peering relationship. Your VCN already has a DRG if you're using an IPSec VPN or an Oracle Cloud Infrastructure FastConnect private virtual circuit.
A remote peering connection (RPC) on each DRG in the peering relationship.
A connection between those two RPCs.
Supporting route rules to enable traffic to flow over the connection, and only to and from select subnets in the respective VCNs (if desired).
Supporting security rules to control the types of traffic allowed to and from the instances in the subnets that need to communicate with the other VCN.

NEW QUESTION # 58
You have launched a compute instance runningOracle database in a private subnet in the Oracle Cloud Infrastructure US East region. You have also created a Service Gateway to back up the data files to OCI Object Storage in the same region. You have modified the security list associated with the private subnet to allow traffic to the Service Gateway, but your instance still cannot access OCI Object Storage. How can you resolve this issue?
- A. Add a stateful rule that enables egress HTTPS (TCP port 443) traffic to OCI Object Storage in the security list associated with the private subnet
- B. Add a rule in the Route Table associated with the private subnet with Target type as "Service Gateway" and destination service as all IAD services in the Oracle Service Network.'
- C. Use the default Security List, which has ports open for OCI Object Storage
- D. Add a stateful rule that enables ingress HTTPS (TOP port 443) traffic to 001 Object Storage in the securitylist associated with the private subnet
Answer: B
Explanation:
Explanation
A service gateway lets your virtual cloudnetwork (VCN) privately access specific Oracle services without exposing the data to the public internet. No internet gateway or NAT 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.
The service gateway is regional and enables access only to supported Oracle services in the same region as the VCN.
For traffic to be routed from a subnet in your VCN to a service gateway, you must add a rule accordingly to the subnet's route table. The rule must use the service gateway as the target. For the destination, you must use the service CIDR label that is enabled for the service gateway. This means that you don't have to know the specific public CIDRs, which could change over time.

NEW QUESTION # 61
You are a network architect andhave designed the network infrastructure of a three-tier application on Oracle Cloud Infrastructure (OCI). In the architecture, back-end DB servers are in a private subnet. One of your DB administrators requests to have access to OCI object storage service.
How can you meet this requirement?
- A. Add a new route rule to the private subnet route table to route default traffic to the internet gateway.
- B. Create a service gateway, add a new route rule to the private subnet route table that uses object storage as target type.
- C. Create a dynamic routing gateway (DRG) and attach it to your virtual cloud network (VCN). Add a default route rule to the private subnets route table and set the target as DRG.
- D. Attach a public IP address to the instances in the private subnet, and then add a new route rule to the private subnet route table to route default traffic to the internet gateway.
Answer: B
Explanation:
Explanation
A service gateway lets resources in your VCN privately access specific Oracle services, without exposing the data to aninternet gateway or NAT. The resources in the VCN can be in a private subnet and use only private IP addresses. The traffic from the VCN to the service of interest travels over the Oracle network fabric and never traverses the internet.
To give your VCN access to a given service CIDR label, you must enable that service CIDR label for the VCN's service gateway. You can do that when you create the service gateway, or later after it's created. You can also disable a service CIDR label for the service gateway at any time.
For traffic to be routed from a subnet in your VCN to a service gateway, you must add a rule accordingly to the subnet's route table. The rule must use the service gateway as the target.
