Oracle 1z0-997-21 問題集

質問 1：
You work for a large bank where security and compliance are critical. As part of the security overview meeting, your company decided to minimize the installation of local tools on your laptop. You have been running Ansible and kubectl to spin up Oracle Container Engine for Kubernetes (OKE) clusters and deployed your application.
For authentication, you are using an Oracle Cloud Infrastructure (OCI) CLI config file that contains OCIDs, Fingerprint, and a locally stored PEM file. Your security team doesn't want you to store any local API key and certificate, or any other local tools.
Which two actions should you perform to spin up the OKE cluster and interact with it? (Choose two.)
A. Create a developer workstation on OCI. Install Ansible and kubectl on it. Use resource principal to authenticate against OCI API and create the OKE Cluster.
B. Create a developer workstation on OCI. Install Ansible and kubectl on it. Use instance principal to authenticate against OCI API and create the OKE Cluster.
C. Develop your own code using OCI SDK to deploy the OKE cluster.
D. Work on OCI Cloud Shell to use built-in Ansible and kubectl to deploy the OKE cluster. Use OCI_CLI_AUTH=instance_obo_user environment variable to authenticate using built-in token.
E. Work on OCI Cloud Shell to use built-in Ansible and kubectl to deploy the OKE cluster. Bring in your own config file and certificate to authenticate against OCI API.

質問 2：
You are working as a solution architect for a customer in Frankfurt, which uses multiple compute instance VMs spread among three Availability Domains in the Oracle Cloud Infrastructure (OCI) eu-frankfurt-1 region. The compute instances do not have public IP addresses and are running in private subnets inside a Virtual Cloud Network (VCN). You have set up OCI Autoscaling feature for the compute instances, but find out that instances cannot be auto scaled. You have enabled monitoring on the instances.
What could be wrong in this situation?
A. Autoscaling only works with single availability domains.
B. You need to assign a reserved public IP address to the compute instances.
C. You need to set up a Service Gateway to send metrics to the OCI Monitoring service.
D. Autoscaling only works for instances with public IP addresses.
正解：C

質問 3：
An E-commerce company which sells computers, tablets, and other electronics items has recently decided to move all of their on-premises infrastructure to Oracle Cloud Infrastructure (OCI). One of their on-premises application is running on an NGINX server and the Oracle Database is running in a 2 node Oracle Real Application Clusters (RAC) configuration.
They cannot afford to have any application down time when they do the migration.
What is an effective mechanism to migrate the customer application to OCI and set up regular automated backups?
A. Launch a compute instance and run an NGINX server to host the application. Deploy a 2 node VM DB Systems with Oracle RAC enabled. Import the on-premises database to OCI VM DB Systems using Oracle Data Pump and then enable automatic backups.
B. Launch a compute instance and run an NGINX server to host the application. Deploy a 2 node VM DB Systems with Oracle RAC enabled. Setup Oracle GoldenGate to synchronize data from their on-premises database to OCIVM Database. Export and Import the on-premises database to OCIVM DB Systems using Oracle Data Pump, apply the GoldenGate trail files to sync up the OCI database with the on-premises database. Enable automatic backups for the OCIVM database and then cutoverthe application from on-premises to OCI.
C. Launch a compute instance and run an NGINX server to host the application. Deploy Exadata Quarter Rack, enable automatic backups and import the database using Oracle Data Pump.
D. Launch a compute instance for both the NGINX application server and the database server. Attach block volumes on the database server compute instance and enable backup policy to backup the block volumes.
正解：B

質問 4：
You are designing the network infrastructure for an application consisting of a web server (server-1) and a Domain Name Server (server-2) running in two different subnets inside the same Virtual Cloud Network (VCN) in Oracle Cloud Infrastructure (OCI). You have a requirement where your end users will access server-1 from the internet and server-2 from your customer's 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: first one with a route to internet via an Internet gateway; associate this route table to the subnet containing server-1 .Configure the second route table to propagate specific routes to the on-premises network via a Dynamic Routing Gateway; associate this route table to subnet containing server-2.
B. Configure a single routing table with two set of rules: one that has route to internet via an Internet Gateway and another that propagates specific routes for the on-premises network via a Dynamic Routing Gateway. Don't associate this routing table with any of the subnets in the VCN.
C. Configure two routing tables that have rules to route all traffic via a Dynamic Routing Gateway. Associate the two routing tables with all the VCN subnets.
D. Configure a single routing table with two set of rules: one that has route to internet via an Internet Gateway and another that propagate specific routes to the on-premises network via a Dynamic Routing Gateway. Associate the routing table with all the VCN subnets.
正解：A

質問 5：
An online registration system Is currently hosted on one large Oracle Cloud Infrastructure (OCT) Bare metal compute Instance with attached block volume to store of the users' dat a. The registration system accepts the Information from the user, Including documents and photos then performs automated verification and processing to check it the user is eligible for registration.
The registration system becomes unavailable at tunes when there is a surge of users using the system the existing architecture needs improvement as it takes a long time for the system to complete the processing and the attached block volumes are not large enough to use data being uploaded by the users.
Which Is the most effective option to achieve a highly scalable solution?
A. Attach more Block volumes as the data volume increase, use Oracle Notification Service (ONS) to distribute tasks to a pool of compute instances working In parallel, and Auto Scaling to dynamically size the pool of Instances depending on the number of notifications received from the Notification Service. Use Resource Manager stacks to replicate your architecture to another region.
B. Upgrade your architecture to use a pool of Bare metal servers and configure them to use their local SSDs for faster data access Set up Oracle Streaming Service (OSS) to distribute the tasks to the pool of Bare metal Instances with Auto Scaling to dynamically increase or decrease the pool of compute instances depending on the length of the Streaming queue.
C. Upgrade your architecture to use more Block volumes as the data volume Increases. Replace the single bare metal instance with a group of compute instances with Auto Scaling to dynamically increase or decrease the compute instance pools depending on the traffic.
D. Change your architecture to use an OCI Object Storage standard tier bucket, replace the single bare metal instance with a Oracle Streaming Service (OSS) to ingest the Incoming requests and distribute the tasks to a group of compute Instances with Auto Scaling
正解：C

質問 6：
Your company developed a function that needs to access the Oracle Database to inject some data to it at runtime. You are tasked to move this function to the Oracle Cloud Infrastructure (OCI) and use Oracle Functions and access Oracle Autonomous Database. You created a Dockerfile below to run this function, however, you are getting this error "cx_Oracle.DatabaseError: ORA""12560: TNS:protocol adapter error".

What should you do to make sure that Oracle Functions can run this Dockerfile properly? (Choose the best answer.)
A. Use """"privileged flag while running the Docker container to add runtime privilege
B. Add these two lines to your Dockerfile: groupadd """"gid 1000 fn && \ adduser """"uid 1000 """"gid fn fn
C. You ned to run this Container as root, so add this line: USER root
D. Use """"cap""add=ALL flag while running the Docker container to add runtime capability

B. It is possible to spill this fileInto multiple parts using the APIs provided by Object Storage.
C. Active multipart upload can be checked by listing all parts that have been uploaded, however It Is not possible to list information for individual object part in an active multipart upload
D. Contiguous numbers need to be assigned for each part so that Object Storage constructs the object by ordering, part numbers in ascending order
