Oracle 1Z0-997 Online Questions & Answers

• Question 51:

  You have deployed a web application targeting a global audience across multiple Oracle Cloud Infrastructure (OCI) regions.

  You decide to use Traffic Management Geo-Location based Steering Policy to serve web requests to users from the region closets to the user. Within each region you have deployed a public load balancer with 4 servers in a backend set.

  During a DR test disable all web servers in one of the regions however, traffic Management does not automatically direct all users to the other region.

  Which two are possible causes?

  A. You did not setup a Route Table associated with load Balancer's subnet
  B. You did not setup an HTTP Health Check associated with Load Balancer public IP in the disabled region.
  C. Rather than using Geo-Location based Steering Policy, you should use Failover Policy Type to serve traffic.
  D. One of the two working web servers In the other region did not pass Its HTTP health check
  E. You did not correctly setup the Load Balancer HTTP health check policy associated with backend set
  B. You did not setup an HTTP Health Check associated with Load Balancer public IP in the disabled region.
  E. You did not correctly setup the Load Balancer HTTP health check policy associated with backend set

  Managing Traffic Management GEOLOCATION Steering Policies Geolocation steering policies distribute DNS traffic to different endpoints based on the location of the end user. Customers can define geographic regions composed of originating continent, countries or states/provinces (North America) and define a separate endpoint or set of endpoints for each region. The Health Checks service allows you to monitor the health of IP addresses and hostnames, as measured from geographic vantage points of your choosing, using HTTP and ping probes. After configuring a health check, you can view the monitor's results. The results include the location from which the host was monitored, the availability of the endpoint, and the date and time the test was performed. Also you can Combine Managing Traffic Management GEOLOCATION Steering Policies with Oracle Health Checks to fail over from one region to another The Load Balancing service provides health status indicators that use your health check policies to report on the general health of your load balancers and their components. if you misconfigure the health check Protocol between the Load balancer and backend set that can lead to not get an accurate response as example below

  If you run a TCP-level health check against an HTTP service, you might not get an accurate response. The TCP handshake can succeed and indicate that the service is up even when the HTTP service is ly configured or having other issues. Although the health check appears good customers might experience transaction failures.

• Question 52:

  You have deployed a multi-tier application with multiple compute instances in Oracle Cloud Infrastructure. You want to back up these volumes and have decided to use Volume Group's feature. The Block volume and Compute instances exist

  in different compartments within your tenancy. Periodically. a few child compartments are moved under different parent compartments, and you notice that sometimes volume group backup fails.

  What could be the cause?

  A. You are exceeding your volume group backup quota configured.
  B. You have the same block volume attached to multiple compute instances; if these compute instances are in different compartments then all concerned compartments must be moved at the same time.
  C. Compute instance with multiple block volumes attached cannot move when a compartment is moved.
  D. The Identity and Access Management policy allowing backup failed to move when the compartment was moved.
  D. The Identity and Access Management policy allowing backup failed to move when the compartment was moved.

  You can move a compartment to a different parent compartment within the same tenancy. When you move a compartment, all its contents (subcompartments and resources) are moved with it. Moving a compartment has implications for the

  contents. After you move a compartment to a new parent compartment, the access policies of the new parent take effect and the policies of the previous parent no longer apply. Before you move a compartment, ensure that:

  You are aware of the policies that govern access to the compartment in its current position. You are aware of the polices in the new parent compartment that will take effect when you move the compartment. In some cases, when moving

  nested compartments with policies that specify the hierarchy, the polices are automatically updated to ensure consistency.

• Question 53:

  A large financial services company has used 2 types of Oracle DB Systems. In Oracle Cloud Infrastructure (OCI) to store user dat.

  One is running on a VM.Standard2.8 shape and the other on a VM.Standard 2.4 shape.

  As business grows, data is growing rapidly on both the databases and performance is also degrading.

  The company wants to address this problem with a viable and economical solution.

  As the solution architect for that company you have suggested that they move their databases to Autonomous Transaction Processing Serverless (ATP-S) database.

  Which two factors should you consider before you arrived at that recommendation?

  A. You verified that ATP S supports the database features and options currently being used by the 2 databases.
  B. Validate that ATP-S will support the storage and processing requirements for the 2 databases over the life cycle of the business applications.
  C. Confirm that ATP-S allows customers to compress tablespaces to reduce storage costs
  D. Upon provisioning, ATP-S automatically scales up CPU to meet the application's processing requirements.
  A. You verified that ATP S supports the database features and options currently being used by the 2 databases.
  B. Validate that ATP-S will support the storage and processing requirements for the 2 databases over the life cycle of the business applications.

  The Oracle Services Network is a conceptual network in Oracle Cloud Infrastructure that is reserved for Oracle services. These services have public IP addresses that you typically reach over the internet. However, you can access the Oracle

  Services Network without the traffic going over the internet.

  There are different ways, depending on which of your hosts need the access:

  Hosts in your on-premises network:

  -

  Private access through a VCN with FastConnect private peering or VPN Connect: The on-premises hosts use private IP addresses and reach the Oracle Services Network by way of the VCN and the VCN's service gateway.

  -

  Public access with FastConnect public peering: The on-premises hosts use public IP addresses. regarding which Fastconnect Public peering: To access public services in Oracle Cloud Infrastructure without using the internet. For example, Object Storage, the Oracle Cloud Infrastructure Console and APIs, or public load balancers in your VCN. Communication across the connection is with IPv4 public IP addresses. Without FastConnect, the traffic destined for public IP addresses would be routed over the internet. With FastConnect, that traffic goes over your private

  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.

• Question 55:

  Policy Attachment When you create a policy you must attach it to a compartment (or the tenancy, which is the root compartment). Where you attach it controls who can then modify it or delete it. If you attach it to the tenancy (in other words, if the policy is in the root compartment), then anyone with access to manage policies in the tenancy can then change or delete it. Typically that's the Administrators group or any similar group you create and give broad access to. Anyone with access only to a child compartment cannot modify or delete that policy. When you attach a policy to a compartment, you must be in that compartment and you must indicate directly in the statement which compartment it applies to. If you are not in the compartment, you'll get an error if you try to attach the policy to a different compartment. Notice that attachment occurs during policy creation, which means a policy can be attached to only one compartment. Policies and Compartment Hierarchies a policy statement must specify the compartment for which access is being granted (or the tenancy). Where you create the policy determines who can update the policy. If you attach the policy to the compartment or its parent, you can simply specify the compartment name. If you attach the policy further up the hierarchy, you must specify the path. The format of the path is each compartment
