NEW QUESTION 39
You have been notified of an application failure indicating that one or more of the Oracle Cloud Infrastructure (OCI) resources have become unavailable. After scanning the Compute and Database consoles, you notice that one of the DB Systems is missing.
What would you do to identify the reason for this missing resource?
- A. Create a serial console connection to the DB System that does not appear in the management console.Connect to the serial console connection, and then review the system logs under/var/log/messages.
- B. Navigate to the Auditconsole and search the previous 24 hours for allDELETErequest actions to get a list of any resource that was deleted in the past 24 hours.
- C. Navigate to the Audit console and search the previous 24 hours for all theGETrequest actions to get a list ofevery event that occurred in the past 24 hours.
- D. View the service limits associated with your account to ensure that you have not exceeded the allowable number of DB Systems in your tenancy.
Answer: B
Explanation:
Explanation
You can filter results by request actions to zero in on only the events with operations that interest you. For example, say that you only want to know about instances that were deleted during a specific time frame. Select a delete request action filter to see only the events with delete operations Reference:https://docs.cloud.oracle.com/en-us/iaas/Content/GSG/Tasks/usingaudit.htm
NEW QUESTION 40
A customer has launched a compute Instance in the Virtual Cloud Network (VCN), which has an Internet gateway, a service gateway, a default security lists and a default route table. Customer has opened up Port 22 in the security lists attached to the compute instance subnet, however is still unable to connect to compute instances using ssh.
Which option would remedy this situation?
- A. Modify the route table associated with the VCN subnet in which the instance resides. Add a following route to the route table.
Destination CIDR: 0.0.0.0/0
Target: Internet Gateway (IGW) - B. Modify the security list associated with the VCN subnet in which the instance resides. Add a stateful egress rule to allow icmp traffic in addition to the port 22.
- C. Modify the route table associated with the VCN subnet in which the instance resides. Add a following route to the route table.
Destination CIDR: 0.0.0.0/0
Target: Dynamic Routing Gateway (DRG) - D. Modify the route table associated with the VCN subnet in which the instance resides. Add a following route to the route table.
Destination CIDR: 0.0.0.0/0
Target: Service Gateway (SGW)
Answer: A
Explanation:
You create an internet gateway in the context of a specific VCN. In other words, the internet gateway is automatically attached to a VCN. However, you can disable and re-enable the internet gateway at any time.
For traffic to flow between a subnet and an internet gateway, you must create a route rule accordingly in the subnet's route table (for example, destination CIDR = 0.0.0.0/0 and target = internet gateway). If the internet gateway is disabled, that means no traffic will flow to or from the internet even if there's a route rule that enables that traffic.
For the purposes of access control, you must specify the compartment where you want the internet gateway to reside. If you're not sure which compartment to use, put the internet gateway in the same compartment as the cloud network.

Your company sells services to photographers where patrons can preview the photos that they want prints for. To avoid unauthorized copies, the sample photos have lower resolution and are watermarked. The photos are processed after they are uploaded. The process is fast but not immediate. It creates samples and sends them to storage outside of the instances.
Which type of instance is ideal for a process like this; short lived and one that keeps the cost low?
- A. Spot instances
- B. On-demand instances
- C. Burstable instances
- D. Preemptible instances
Answer: D
NEW QUESTION 42

- A. a security list that is open on a listener port
- B. a listener
- C. a certificate
- D. a back-end server
- E. a back end set

Explanation:
https://docs.cloud.oracle.com/iaas/Content/Balance/Tasks/managingloadbalancer.htm?tocpath=Services%7CLoad%20Balancing%7C_____5 The essential components for load balancing include: * A load balancer with pre-provisioned bandwidth. * A backend set with a health check policy. See Managing Backend Sets. * Backend servers for your backend set. See Managing Backend Servers. * One or more listeners . See Managing Load Balancer Listeners. * Load balancer subnet security rules to allow the intended traffic. To learn more about these rules, see Security Rules. * Optionally, you can associate your listeners with SSL server certificate bundles to manage how your system handles SSL traffic. See Managing SSL Certificates.
NEW QUESTION 43
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. Create a Dynamic Routing Gateway (DRG) and route your private IP traffic to the DRG.
- B. Disable "Source and Destination Check" on the VNIC of your Linux instance.
- C. There is no way that a private subnet can connect to the Internet.
- D. Restart the NAT instance.
Answer: B
Explanation:
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.
