Which of the following is not a core characteristic of cloud computing as defined byNIST standards? A. On-demand self-service access B. Upfront license payments C. Rapid elasticity D. Measured services - ANS:->> B RATIONALE:A, C, D are characteristics as defined by NIST; cloud computing enables pay-as-you-pricing and does not involve paying for licenses upfront. Which statement below is NOT correct regarding a highly available system? A. Highly available systems always involve manual intervention to maintain high availability. B. Highly available systems typically have redundant hardware and softwareC. Highly availability systems avoid having single points-of- failure D. Highly available systems involve a failover process that moves processing performedby the failed component to the backup component - ANS:->> A RATIONALE: It is possible to have some manual intervention, but typically, highly available systems do not involve manual failover processes. The more transparent the failover is, the morehighly available the system is.
What does compute vertical scaling imply? A. Compute scaling out is called vertical scalingB. Compute scaling in is called vertical scaling C. Compute scaling up (or down) is called vertical scaling D. In cloud, you can cannot scale compute instances - **ANS:-

logical not physicalisolation. Which two are valid reasons to deploy your apps in multiple Oracle Cloud Infrastructureregions? A. To mitigate the risk of region-wide events such as large weather systems orearthquakes B. To achieve high availability and real time data synchronization C. To meet varying requirements for legal jurisdictions, tax domains, and other businessor social criteria D. To lower costs, as some OCI regions have lower pricing than others - ANS:-
A, C RATIONALE: In OCI, pricing is not region-specific. In addition, if you deploy apps to multiple regions,you cannot achieve real-time data synchronization as regions can be separated by vastdistances—across countries or even continents You have two web servers and a clustered database running in a single OCI AvailabilityDomain. Which step below can help you achieve high availability? A. Group one web server and one database node in one fault domain and the other half of each pair in another fault domain B. OCI provides high availability by default, so you don't need to do anything C. Put both web servers in the same fault domain and database nodes in another faultdomain D. Put both database nodes in the same fault domain and web servers in another
faultdomain - ANS:->> A RATIONALE: Grouping web server and a database node and placing a pair in two separate fault domains ensure that a failure of any one fault domain does not result in an outage foryour application.

Through an Internet gateway - ANS:->> C RATIONALE:NAT is a networking technique commonly used to give an entire private network accessto the internet without assigning each host a public IP address. OCI provides a managed NAT Gateway service that gives cloud resources without public IP addressesaccess to the internet without exposing those resources to incoming internet connections.

D. Dynamic Routing GatewayE. VPN Gateway
- ANS:->> D DRG is a virtual router that provides a path for private traffic (that is, traffic that usesprivate IPv4 addresses) between your VCN and an on-premises network.

Instance Level E. Gateways Level - ANS:->> C, D NSG rules apply to an instance (vNIC) while Security Lists applies at the subnet level(and all instances in that particular subnet). If you choose to use both, a packet is allowed if any rule in any of the relevant Security Lists and Network Security Groups allows the traffic Which of the following is NOT true about Oracle Cloud Infrastructure Object Storageservice? A. Maximum object size that can be stored in OCI Object Storage buckets is 10 TB.B. Standard Object storage buckets cannot be downgraded to Archive
storage. C. Archive Storage buckets cannot be upgraded to Standard Object storage.D. Object Storage is eventually consistent. - ANS:->> D OCI Object Storage supports strong consistency that means that when a read request ismade, Object Storage always serves the most recent copy of the data that was written to the system. You have a requirement to store application backups in OCI for 6-12 months, but retrieve data immediately based on business needs. Which OCI storage service can beused to meet this requirement? A. Object Storage (standard)B. Block Volume C. Archive Storage D. File Storage - ANS:->> A You can use Object Storage for data to which you need fast, immediate, and frequent access. You can use Archive Storage for data to which you seldom or rarely access, butthat must be retained and preserved for long periods. Which Oracle Cloud Infrastructure storage service can provide a shared file systemacross multiple compute instances? A. File Storage B. Archive StorageC. Object

Oracle Container Engine for KubernetesC. OCI Bare Metal D. OCI Virtual Machine - ANS:->> A The serverless and elastic architecture of Oracle Functions means there is no need toprovision or maintain compute instances, and operating system software patches andupgrades. You can deploy your code and call it directly or trigger it in response to events. You are planning to deploy Oracle JDE on Oracle Cloud Infrastructure (OCI).
