  Explanation/Reference:

  Oracle Functions is a fully managed, multi-tenant, highly scalable, on-demand, Functions- as-a-Service platform. It is built on enterprise-grade Oracle Cloud Infrastructure and powered by the Fn Project open source engine. Use Oracle Functions (sometimes abbreviated to just Functions) when you want to focus on writing code to meet business needs. The serverless and elastic architecture of Oracle Functions means there's no infrastructure administration or software administration for you to perform. You don't provision or maintain compute instances, and operating system software patches and upgrades are applied automatically. Oracle Functions simply ensures your app is highly-available, scalable, secure, and monitored. With Oracle Functions, you can write code in Java, Python, Node, Go, and Ruby (and for advanced use cases, bring your own Dockerfile, and Graal VM). You can then deploy your code, call it directly or trigger it in response to events, and get billed only for the resources consumed during the execution.

  You can create automation based on state changes for your Oracle Cloud Infrastructure resources by using event types, rules, and actions. When the function is executing inside the container, the function can read from and write to other resources and services running in the same subnet (for example, Database as a Service). The function can also read from and write to other shared resources (for example, Object Storage), and other Oracle Cloud Services.

• Question 115:

  You have been asked to implement a bespoke financial application in Oracle Cloud Infrastructure using virtual machine instances controlled by Autoscaling across multiple Availability Domains. The application stores transaction logs, intermediate transaction data, and audit data and needs to store this on a persistent, durable data store accessible from all of the application servers. The application requires the file system to be mounted in the /audit folder on the Linux file system. The system needs to tolerate the failure of two or more Fault Domains and still maintain data integrity. The solution should be as low maintenance as possible.

  What storage architecture should you suggest?

  A. Use locally attached NVMe instances and configure RAID 0 replication between servers.
  B. Implement a single instance and install an NFS server, configure and create an NFS share, and mount this as /audit on the application instances.
  C. Store the data on Oracle Object Storage mounted at the /audit mount point on all the Linux instances using the default mount options.
  D. Use File Storage Service(FSS). Configure FSS to operate from all Availability Domains the application servers operate in and mount the file system in the /audit folder.
  D. Use File Storage Service(FSS). Configure FSS to operate from all Availability Domains the application servers operate in and mount the file system in the /audit folder.

• Question 116:

  A retail company runs their online shopping platform entirely on Oracle cloud Infrastructure (OCI). This is a 3-tier web application that Includes a Mbps Load Balancer. Virtual Machine Instances for web and an Oracle DB Systems Virtual Machine Due to unprecedented growth, they noticed an Increase in the Incoming traffic to their website and all users start getting 503 (Service Unavailable) errors.

  What is the potential problem in this scenario?

  A. The Load Balancer health check status Indicates critical situation for half of the backend webservers
  B. All the web servers are too busy and not able to answer any request from users.
  C. The Database Is down hence users can not access the web site
  D. The Traffic Management Policy is not set to load Balancer the traffic to the web servers.
  E. You did not configure a Service Gateway to allow connection between web servers and load Balance
  B. All the web servers are too busy and not able to answer any request from users.

  ---

  Explanation/Reference:

  A 503 Service Unavailable Error is an HTTP response status code indicating that a server is temporarily unable to handle the request. This may be due to the server being overloaded or down for maintenance.

• Question 117:

  Give this compartment structure:

  

  You want to move a compute instance that is in 'Compute' compartment to 'SysTes-Team'. You login to your Oracle Cloud Infrastructure (OCI)account and use the 'Move Resource' option.

  What will happen when you attempt moving the compute resource?

  A. The move will be successful though Compute Instance and its Public and Private IP address will stay the same. The Compute instance VNIC will need to be moved separately. The Compute instance will still be associated with the original VCN.
  B. The move will fail and you will be prompted to move the VCN first. Once VCN is moved to the target compartment, the Compute instance can be moved.
  C. The move will be successful though Compute Instance Public and Private IP address changed, and it will be associated to the VCN in target compartment.
  D. The move will be successful though Compute Instance and its Public and Private IP address will stay the same. The Compute instance VNIC will still be associated with the original VCN.
  D. The move will be successful though Compute Instance and its Public and Private IP address will stay the same. The Compute instance VNIC will still be associated with the original VCN.

  Explanation/Reference:

  Moving Resources to a Different Compartment

  Most resources can be moved after they are created. There are a few resources that you can't move from one compartment to another. Some resources have attached resource dependencies and some don't.

  Not all attached dependencies behave the same way when the parent resource moves. For some resources, the attached dependencies move with the parent resource to the new compartment.

  The parent resource moves immediately, but in some cases attached dependencies move asynchronously and are not visible in the new compartment until the move is complete. For other resources, the attached resource dependencies do

  not move to the new compartment. You can move these attached resources independently. You can move Compute resources such as instances, instance pools, and custom images from one compartment to another. When you move a

  Compute resource to a new compartment, associated resources such as boot volumes and VNICs are not moved. You can move a VCN from one compartment to another. When you move a VCN, its associated VNICs, private IPs, and

  ephemeral IPs move with it to the new compartment.

• Question 118:

  A data analytics company has been building Its now generation big data and analytics platform on Oracle Cloud Infrastructure (OCI). They need a storage service that provide the scale and performance that their big data applications require such as high throughput to compute nodes with low latency file operations in addition, their data needs to be stored redundantly across multiple nodes In a single availability domain and allows concurrent connections from multiple compute Instances hosted on multiple availability domains. Which OCI storage service can you use to meet i his requirement?

  A. Object Storage
  B. File System Storage
  C. Archive storage
  D. Block Volume
  B. File System Storage

  Explanation/Reference:

  Oracle Cloud Infrastructure File Storage service provides a durable, scalable, secure, enterprise-grade network file system. You can connect to a File Storage service file system from any bare metal, virtual machine, or container instance in your Virtual Cloud Network (VCN). You can also access a file system from outside the VCN using Oracle Cloud Infrastructure FastConnect and Internet Protocol security (IPSec) virtual private network (VPN). Use the File Storage service when your application or workload includes big data and analytics, media processing, or content management, and you require Portable Operating System Interface (POSIX)- compliant file system access semantics and concurrently accessible storage. The File Storage service is designed to meet the needs of applications and users that need an enterprise file system across a wide range of use cases

• Question 119:

  You have two Virtual Cloud Networks (VCN) that need to be peered. The set up is as follows:

  The VCNs are in different tenancies.

  Peering has to be via Local Peering Gateway (LPG) because one of the VCNs needs to be added to an existing Hub and Spoke configuration that consists of a hub and two spokes.

  There is a CIDR overlap. The VCN that serves as the Hub VCN has a 172.19.0.0/16 CIDR prefix. The other VCN to be added as a Spoke VCN has a 172.19.128.0/17 CIDR prefix.

  The other two spokes have 10.0.0.0/16 and 192.168.0.0/16 prefixes, respectively.

  What is a possible solution to this problem?

  A. Use Dynamic Routing Gateway (DRG) instead.
  B. Add another CIDR prefix to the VCN that is integrating with the Hub and Spoke and does not overlap. Use that CIDR for the LPG connection.
  C. Review the subnets in the hub VCN. If they all have the third octet under 128, change the VCN prefix to /17.
  D. Review the subnets in the hub VCN. If they all have the third octet above 128, change the VCN prefix to /17.
  E. Review all subnets in the hub VCN. If one of them has the third octet at 128, change the VCN prefix to /17.
  B. Add another CIDR prefix to the VCN that is integrating with the Hub and Spoke and does not overlap. Use that CIDR for the LPG connection.

• Question 120:

  You have been asked to review some network proposals by a major client. The client's IT director needs to provision two Virtual Cloud Network (VCN) for a major application. Both applications use a large number of virtual machine instances, and so will ideally occupy VCNs with as many address spaces as possible. Additionally, in the future, VCN peering will be required to allow communication between the VCNs.

  Which of the following are valid IP ranges to consider for the VCNs?

  A. 10.0.0.0/24 and 10.0.1.0/24
  B. 10.0.1.0/24 and 10.0.1.0/27
  C. 10.0.0.0/16 and 10.0.64.0/24
  D. 10.0.0.0/8 and 11.0.0.0/8
  A. 10.0.0.0/24 and 10.0.1.0/24
