NEW QUESTION 67
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. Stop sending traffic to the instance that failed health check
- B. Remove the instance that failed the health check from the backend set
- C. Terminate the instance that failed health check
- D. Stop the instances that failed health check
Answer: A
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. If a 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 reduce your application maintenance window.

You need to create a high performance shared file system, and have been advised to use file storage service (FSS). You have logged into the Oracle Cloud Infrastructure console, created a file system, and followed the steps to mount the shared file system on your Linux instance. However, you are still unable to access the shared file system from your Linux instance.
What is the likely reason for this?
- A. There are no security list rules for mount target traffic
- B. There is no route in your virtual cloud network's (VCN) route table for mount target traffic
- C. There is no internet gateway (IGW) set up for mount target traffic
- D. There is no Identity and Access Management (IAM) policies set up to allow you to access the mount target
Answer: A
Explanation:
Explanation
Virtual firewall rules for your VCN. Your VCN comes with a default security list, and you can add more.
These security lists provide ingress and egress rules that specify the types of traffic allowed in and out of the instances. You can choose whether a given rule is stateful or stateless. Security list rules must be set up so that clients can connect to file system mount targets. For more information about how security lists work in Oracle Cloud Infrastructure, see Security Lists in the Networking documentation. For information about setting up specific security list rules required for mount target traffic, see Configuring VCN Security List Rules for File Storage. About Security explains how security lists interact with other types of security in your file system.

NEW QUESTION 74
Which two statements are true about Oracle Cloud Infrastructure (OCI) DB Systems Data Guard service?
- A. Data guard implementation for Bare Metal shapes requires two DB Systems, one containing the primary database and one containing the standby database.
- B. Data guard implementation requires two DB Systems, one running the primary database on a virtual machine and the standby database running on bare metal.
- C. Both DB systems must use the same VCN, and port 1521 must be open
- D. Data guard configuration on the OCI is limited to a virtual machine only
Answer: A,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.
- 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 75
When creating a subnet, one or more placeholder security lists are often associated with the subnet. Why?
- A. It is not possible to add or remove security lists after a subnet is created.
- B. Each network endpoint or instance in the subnet needs its own security list.

NEW QUESTION 76
You have five different company locations spread across the US. For a proof-of-concept (POC) you need to setup secure and encrypted connectivity to your workloads running in a single virtual cloud network (VCN) in the Oracle Cloud Infrastructure Ashburn region from all company locations.
What would meet this requirement?
- A. Create five IPsec connections with each company location and terminate those connections on a single DRG. Attach that DRG to your VCN.
- B. Create five IPsec VPN connections with each company location and terminate those connections on five separate DRGs. Attach those DRGs to your VCN.
- C. Create five internet gateways in your VCN and have separate route table for each internet gateway.
- D. Create five virtual circuits using FastConnect for each company location and terminate those connections on a single dynamic routing gateway (DRG). Attach that DRG to your VCN.
Answer: A
Explanation:
Explanation
Access to Your On-Premises Network
There are two ways to connect your on-premises network to Oracle Cloud Infrastructure:
VPN Connect: Offers multiple IPSec tunnels between your existing network's edge and your VCN, by way of a DRG that you create and attach to your VCN.
Oracle Cloud Infrastructure FastConnect: Offers a private connection between your existing network's edge and Oracle Cloud Infrastructure. Traffic does not traverse the internet. Both private peering and public peering are supported. That means your on-premises hosts can access private IPv4 addresses in your VCN as well as regional public IPv4 addresses in Oracle Cloud Infrastructure (for example, Object Storage or public load balancers in your VCN).
You can use one or both types of the preceding connections. If you use both, you can use them simultaneously, or in a redundant configuration. These connections come to your VCN by way of a single DRG that you create and attach to your VCN. Without that DRG attachment and a route rule for the DRG, traffic does not flow between your VCN and on-premises network. At any time, you can detach the DRG from your VCN but maintain all the remaining components that form the rest of the connection. You could then reattach the DRG again, or attach it to another VCN.
NEW QUESTION 77
Which of the following statement is true regarding Oracle Cloud Infrastructure Object Storage Pre-Authenticated Requests?
- A. Changing the bucket visibility does not change existing pre-authenticated requests
- B. Pre-authenticated requests don't have an expiration
- C. It is not possible to create pre-authenticated requests for the buckets, but only for the objects
- D. It Is not possible to create pre-authenticated requests for "archive" storage tier
Answer: A
Explanation:
Pre-authenticated requests provide a way to let users access a bucket or an object without having their own credentials, as long as the request creator has permissions to access those objects. For example, you can create a request that lets an operations support user upload backups to a bucket without owning API keys. Or, you can create a request that lets a business partner update shared data in a bucket without owning API keys.
When you create a pre-authenticated request, a unique URL is generated. Anyone you provide this URL to can access the Object Storage resources identified in the pre-authenticated request, using standard HTTP tools like curl and wget.
Understand the following scope and constraints regarding pre-authenticated requests:
Users can't list bucket contents.
You can create an unlimited number of pre-authenticated requests.
There is no time limit to the expiration date that you can set.
You can't edit a pre-authenticated request. If you want to change user access options in response to changing requirements, you must create a new pre-authenticated request.
The target and actions for a pre-authenticated request are based on the creator's permissions. The request is not, however, bound to the creator's account login credentials. If the creator's login credentials change, a pre-authenticated request is not affected.
You cannot delete a bucket that has a pre-authenticated request associated with that bucket or with an object in that bucket.
Understand the following scope and constraints regarding public access:
Changing the type of access is bi-directional. You can change a bucket's access from public to private or from private to public.
Changing the type of access doesn't affect existing pre-authenticated requests. Existing pre-authenticated requests still work.
NEW QUESTION 78

- object storage). You want other Internet traffic from your on-premises environment to use your existing connection with your ISP.
What is the correct way to establish OCI FastConnect to access these OCI public endpoints?
- A. Configure private peering on your FastConnect link with a static route that points to OCI object storage service.
- B. Configure public peering on your FastConnect link with a static route that points to OCI object storage service.
- C. Configure public peering on your FastConnect link. Redistribute BGP routes learned into your existing routing table and advertise a specific route for your network infrastructure to OCI.
- D. Configure private peering on your FastConnect link. Redistribute BGP routes learned into your existing routing table and advertise a default from your network infrastructure to OCI.

- D. It is not possible to meet this requirement
- E. Create Object Storage Lifecycle rules to delete objects from the legacy bucket after 365 days with a filter type - exclude by pattern: ''.xlsx"
Answer: C,E
Explanation:
Object Lifecycle Management lets you automatically manage the archiving and deletion of objects. By using Object Lifecycle Management to manage your Object Storage and Archive Storage data, you can reduce your storage costs and the amount of time you spend managing data.
Use object name filters to specify which objects the lifecycle rule applies to.
You can add object filters in any order. Object Lifecycle Management evaluates the precedence of the rules as follows:
Pattern exclusions
Pattern inclusions
Prefix inclusions
