質問 1：
An organization has its mission critical application consisting of multiple application servers and databases running inside Virtual Cloud Network (VCN) in uk-london-1 region. Their solution architect wants to further strengthen their architecture by planning for Disaster Recovery (DR) in eu-frankfurt-1 region.
Which two solutions should their architect keep in mind while designing for DR?
A. It is not possible to use Active Data Guard to synchronize a database in uk-london-1 region to equivalent database in eu-frankfurt-1 region.
B. The RTO is the acceptable timeframe of lost data that application can tolerate.
C. Load balancer will automatically distribute traffic between both the regions.
D. rsync utility can be used to asynchronously copy file systems or snapshot data to another region.
E. A remote VCN peering connection is required to establish secure and reliable connectivity between different VCNs created in uk-london-1 and eu-frankfurt-1 region.
正解：C,E

質問 2：
A cloud consultant is working on implementation project on OCI. As part of the compliance requirements, the objects placed in object storage should be automatically archived first and then deleted. He is testing a Lifecycle Policy on Object Storage and created a policy as below:
[ { "name": "Archive_doc", "action": "ARCHIVE", "objectNameFilter": { "inclusionPrefixes": "doc"] },
"timeAmount": 5, "timeunit": "DAYS", "isEnabled": true },
{ "name": "Delete_doc", "action": "DELETE", "objectNameFilter": "inclusionPrefixes": [ "doc"]
1."timeAmount": 5, "timeunit": "DAYS", "isEnabled": true }
What will happen after this policy is applied?
A. All objects with names starting with "doc" will be deleted after 5 days of object creation
B. All the objects having file extension ".doc" will be archived for 5 days and will be deleted 10 days after object creation
C. All the objects having file extension ".doc" will be archived 5 days after object creation
D. All the objects with names starting with "doc" will be archived 5 days after object creation and will be deleted 5 days after archival

質問 3：
You are designing the network infrastructure for two application servers: appserver-1 and appserver-2 running in two different subnets inside the same Virtual Cloud Network (VCN) Oracle Cloud Infrastructure (OCI). You have a requirement where your end users will access appserver-1 from the internet and appserver-2 from the on-premises network. The on-premises network is connected to your VCN over a FastConnect virtual circuit.
How should you design your routing configuration to meet these requirements?
A. Configure two routing tables: Route Table-1 that has a route to internet via the Internet gateway. Associate this route table to the subnet containing appserver-1. Route Table-2 that propagate specific routes for the on-premises network via the Dynamic Routing Gateway (DRG) Associate this route table to subnet containing appserver-2.
B. Configure a single routing table (Routing Table-1) that has two set of rules: one that has route to internet via the Internet Gateway and another that propagates specific routes for the on-premises network via Dynamic Routing Gateway (DRG). Associate the routing table with the VCN.
C. Configure two routing table (Route table-1 Route Table-2) that have rule to route all traffic via the Dynamic Routing Gateway (DRG) Associate the two routing tables with all the VCN subnets.
D. Configure a single routing table (Route Table-1) that has two set of rules. One that has route to internet via the internet Gateway and another that propagate specific routes for the on-premise network via the Dynamic Routing Gateway. Associate the routing table with all the VCN subnets.

質問 4：
An OCI Architect is working on a solution consisting of analysis of data from clinical trials of a pharmaceutical company. The data is being stored in OCI Autonomous Data Warehouse (ADW) having 8 CPU Cores and 70 TB of storage. The architect is planning to setup autoscaling to respond to dynamic changes in the workload.
Which of the following needs to be considered while configuring auto scaling? Choose two
A. The maximum CPU cores that will be automatically allocated for this database is 16 CPUs
B. Auto scaling also scales IO throughput linearly along with CPU
C. The database memory SGA and PGA will not get affected by the changes in the number of CPUs during auto scaling
D. Enabling auto scaling does not change the concurrency and parallelism settings
正解：B,D

What additional information do you need from customer in order to recommend a suitable migration method? Choose two
A. Elapsed time since database was last patched
B. Top 5 longest running queries
C. Number of active connections
D. Data types used in the on-premises database
E. On-premises host operating system and version
正解：D,E

質問 6：
You are working as a solutions architect for an online retail store In Frankfurt which uses multiple compute instance VMs spread among three availability domains In the eu-frankfurt-1 region.
You noticed the website Is having very high traffic, so you enabled autoscaling to sun tee me no f your application but, you observed that one of the availability domains is not receiving any traffic.
What could be wrong In this situation?
A. Autoscaling can be enabled for multiple availability domains only in uk-london t region.
B. You have to manually acid all three availability domains to your load balancer configuration.
C. Autoscaling only works with single availability domains.
D. You forgot to attach a load balancer to your instance pool configuration.
E. Autoscaling is using an Instance Pool configured to create instances in two availability Domains.

質問 7：
All three Data Guard Configuration are fully supported on Oracle Cloud infrastructure (OCI). You want to deploy a maximum availability architecture (MAA) for database workload.
Which option should you consider while designing your Data Guard configuration to ensure best RTO and PRO without causing any data loss?
A. Configure ''Maximum Availability" mode in SYNC mode between two availability domains (same region), and use the Maximum Availability mode in SYNC mode between two regions.
B. Configure ''Maximum Scalability" mode which provides the highest level of scalability without compromising the availability of the primary database.
C. Configure "Maximum Protection" mode which provides zero data loss If the primary database fails.
D. Configure "Maximum Performance" mode In SYNC mode between two availability domains (same region) which provides, the highest level of data protection that is possible without affecting the performance of the primary database.
正解：A
