However, after creating several compute instances In the public subnet, none can reach the Internet. Which two are possible reasons for the connectivity Issue?
A. A NAT gateway is needed to enable the communication flow to internet. 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. The route table has no default route for routing traffic to the internet gateway. E. There is no stateful ingress rule in the security list associated with the public subnet.
B. There Is no stateful egress rule In the security list associated with the public subnet. D. The route table has no default route for routing traffic to the internet gateway.
Question 74:
You are the Solutions Architect of a large company and are tasked with migrating all your services to Oracle Cloud Infrastructure. As part of this, you first design a Virtual Cloud Network (VCN) with a public subnet and a private subnet. Then in order to provide Internet connectivity to the instances in your private subnet, you create an Oracle Linux instance in your public subnet and configure NAT on it. However, even after adding all related security list rules and routes in the Route Table, your private subnet instances still cannot connect to the Internet. Which action should you perform to enable Internet connectivity?
A. Disable "Source and Destination Check" on the VNIC of your Linux instance. B. There is no way that a private subnet can connect to the Internet. C. Create a Dynamic Routing Gateway (DRG) and route your private IP traffic to the DRG. D. Restart the NAT instance.
A. Disable "Source and Destination Check" on the VNIC of your Linux instance.
https://docs.cloud.oracle.com/iaas/Content/Network/Tasks/managingVNICs.htm#Source/D By default, every VNIC performs the source/destination check on its network traffic. The VNIC looks at the source and destination listed in the header
of each network packet. If the VNIC is not the source or destination, then the packet is dropped.
If the VNIC needs to forward traffic (for example, if it needs to perform Network Address Translation (NAT)), you must disable the source/destination check on the VNIC. For instructions, see To update an existing VNIC. For information about
the general scenario, see Using a Private IP as a Route Target.
Question 75:
You are in the process of setting up a highly available student registration website on Oracle Cloud Infrastructure (OCI). You use a load balancer and a database service on OCI. You launch two compute instances each in a different subnet
and add them to the back end set of a public load balancer. The load balancer is configured correctly and working. You then deploy the student registration application on these two compute instances. The application can communicate with
the database service. However, when you type the URL of this student registration application in your browser, no web page appears.
What could be the cause?
A. The security lists of the subnets on which the two instances are located do not have "allow" rules for port 80 and 443. B. The load balancer performed a health check on the application and found that compute instances were not in a healthy state and terminated the instances. C. The client requested https access to the application and the load balancer service does not support end-to-end SSL from the client to the listener to the back-end set. D. The Dynamic Routing Gateway is preventing the client traffic from your data center network from reaching the public IP of the load balancer.
A. The security lists of the subnets on which the two instances are located do not have "allow" rules for port 80 and 443.
Question 76:
Which two statements are true about data guard service on DB Systems in Oracle Cloud Infrastructure (OCI)?
A. Data guard implementation requires two DB Systems, one running the primary database on a virtual machine and the standby database running on bare metal. B. Data guard implementation requires two DB Systems, one containing the primary database and one containing the standby database. C. Data guard configuration on the OCI is limited to a virtual machine only. D. Both DB Systems must use the same VCN, and port 1521 must be open.
B. Data guard implementation requires two DB Systems, one containing the primary database and one containing the standby database. D. Both DB Systems must use the same VCN, and port 1521 must be open.
Question 77:
You create an autoscaling configuration of Linux compute instances in Oracle Cloud Infrastructure (OCI). You noticed that your application is running slow. After checking your compute instances, you noticed that autoscaling is not launching
additional instances,
even though the existing compute instances already have high memory usage.
How can you resolve this issue?
A. Modify the scaling policy to monitor memory usage and scale up the number of instances when it meets the threshold. B. Modify the scaling policy to monitor CPU usage and scale up the number of instances when it meets the threshold. C. Install the monitoring agent to all compute instances which will trigger the autoscaling group. D. Install OCI SDK in all compute instances and create a script that will trigger the autoscaling event if there is high memory usage.
B. Modify the scaling policy to monitor CPU usage and scale up the number of instances when it meets the threshold.
Question 78:
You are deploying a highly available web application In Oracle Cloud Infrastructure and have decided to use a public load balancer. The back-end web servers will be distributed across all three availability domains (ADs). How many subnets should you create to deliver a secure, highly available application?
A. two subnets in total; one regional private subnet to host your back-end web servers and one regional public subnet to host your public load load balancer. B. two subnets in total; one regional public subnet to host your back-end web servers and one regional private subnet to host your public load load balancer. C. three subnets in total; one regional public subnet to host your back-end web servers and two AD specific private subnets to host your private load load balancer. D. one subnet in total; one regional private subnet to host your back-end web servers and your public load balancer.
A. two subnets in total; one regional private subnet to host your back-end web servers and one regional public subnet to host your public load load balancer.
To accept traffic from the internet, you create a public load balancer. The service assigns it a public IP address that serves as the entry point for incoming traffic. You can associate the public IP address with a friendly DNS name through any DNS vendor. A public load balancer is regional in scope. If your region includes multiple availability domains, a public load balancer requires either a regional subnet (recommended) or two availability domain- specific (AD-specific) subnets, each in a separate availability domain. With a regional subnet, the Load Balancing service creates a primary load balancer and a standby load balancer, each in a different availability domain, to ensure accessibility even during an availability domain outage. If you create a load balancer in two AD-specific subnets, one subnet hosts the primary load balancer and the other hosts a standby load balancer. If the primary load balancer fails, the public IP address switches to the secondary load balancer. The service treats the two load balancers as equivalent and you cannot specify which one is "primary". Whether you use regional or AD-specific subnets, each load balancer requires one private IP address from its host subnet. The Load Balancing service supplies a floating public IP address to the primary load balancer. The floating public IP address does not come from your backend subnets. You cannot specify a private subnet for your public load balancer. The backend servers (Compute instances) associated with a backend set can exist anywhere, as long as the associated network security groups (NSGs), security lists, and route tables allow the intended traffic flow. Oracle recommends that you create your load balancer in a regional subnet. Oracle recommends that you distribute your backend servers across all availability domains within the region.
