NEW QUESTION 48
Your company will soon start moving critical systems Into Oracle Cloud Infrastructure (OCI) platform. These systems will reside in the us-phoenix-1and us-ashburn 1 regions. As part of the migration planning, you are reviewing the company's existing security policies and written guidelines for the OCI platform usage within the company. you have to work with the company managed key.
Which two options ensure compliance with this policy?
- A. When you create a new compute instance through OCI console, you use the default options for "configure boot volume" to speed up the process to create this compute instance.
- B. When you create a new block volume through OCI console, select Encrypt using Key Management checkbox and use encryption keys generated and stored in OCI Key Management Service.
- C. When you create a new OCI Object Storage bucket through OCI console, you need to choose "ENCRYPT USING CUSTOMER-MANAGED KEYS" option.
- D. When you create a new compute instance through OCI console, you use the default shape to speed up the process to create this compute instance.
- E. You do not need to perform any additional actions because the OCI Block Volume service always encrypts all block volumes, boot volumes, and volume backups at rest by using the Advanced Encryption Standard (AES) algorithm with 256-bit encryption.
Answer: B,C
Explanation:
Block Volume Encryption
By default all volumes and their backups are encrypted using the Oracle-provided encryption keys. Each time a volume is cloned or restored from a backup the volume is assigned a new unique encryption key.
You have the option to encrypt all of your volumes and their backups using the keys that you own and manage using the Vault service.If you do not configure a volume to use the Vault service or you later unassign a key from the volume, the Block Volume service uses the Oracle-provided encryption key instead.
This applies to both encryption at-rest and in-transit encryption.
Object Storage Encryption
Object Storage employs 256-bit Advanced Encryption Standard (AES-256) to encrypt object data on the server. Each object is encrypted with its own data encryption key. Data encryption keys are always encrypted with a master encryption key that is assigned to the bucket. Encryption is enabled by default and cannot be turned off. By default, Oracle manages the master encryption key. However, you can optionally configure a bucket so that it's assigned an Oracle Cloud Infrastructure Vault master encryption key that you control and rotate on your own schedule.
Encryption: Buckets are encrypted with keys managed by Oracle by default, but you can optionally encrypt the data in this bucket using your own Vault encryption key. To use Vault for your encryption needs, select Encrypt Using Customer-Managed Keys. Then, select the Vault Compartment and Vault that contain the master encryption key you want to use. Also select the Master Encryption Key Compartment and Master Encryption Key.

NEW QUESTION 51
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. Auto scaling also scales IO throughput linearly along with CPU
- B. The maximum CPU cores that will be automatically allocated for this database is 16 CPUs
- 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
Answer: A,D
Explanation:
Auto scaling is enabled by default when you create an Autonomous Database instance or you can use Scale Up/Down on the Oracle Cloud Infrastructure console to enable or disable auto scaling.
With auto scaling enabled the database can use up to three times more CPU and IO resources than specified by the number of OCPUs currently shown in the Scale Up/Down dialog. When auto scaling is enabled, if your workload requires additional CPU and IO resources the database automatically uses the resources without any manual intervention required.
Enabling auto scaling does not change the concurrency and parallelism settings for the predefined services IO throughput depends on the number of CPUs you provision and scales linearly with the number of CPUs.
NEW QUESTION 52
A customer is in a process of shifting their web based Sales application from their own data center located in US West to OCI India West (Mumbai) region. They want to do it in a controlled manner and initially only 1% of the traffic will be steered to the servers in OCI. After verification of everything is working as expected, the company is gradually planning to increase the ratio until they are comfortable with fully migrating all traffic to OCI.
Which of the following solution can be used in this situation?
- A. OCI DNS and Traffic Management with Load Balancer Steering policy
- B. OCI DNS and Traffic Management with Geolocation Steering policy
- C. OCI DNS and OCI Load Balancer Service
- D. OCI DNS and Traffic Management with Failover Steering policy
Answer: A
Explanation:
STEERING POLICIES is A framework to define the traffic management behavior for your zones. Steering policies contain rules that help to intelligently serve DNS answers.
FAILOVER
Failover policies allow you to prioritize the order in which you want answers served in a policy (for example, Primary and Secondary). Oracle Cloud Infrastructure Health Checks are leveraged to determine the health of answers in the policy. If the Primary Answer is determined to be unhealthy, DNS traffic will automatically be steered to the Secondary Answer.
LOAD_BALANCE
Load Balancer policies allow distribution of traffic across multiple endpoints. Endpoints can be assigned equal weights to distribute traffic evenly across the endpoints or custom weights may be assigned for ratio load balancing. Oracle Cloud Infrastructure Health Checks are leveraged to determine the health of the endpoint. DNS traffic will be automatically distributed to the other endpoints, if an endpoint is determined to be unhealthy.
ROUTE_BY_GEO
Geolocation-based 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.
ROUTE_BY_ASN
ASN-based steering policies enable you to steer DNS traffic based on Autonomous System Numbers (ASN).
DNS queries originating from a specific ASN or set of ASNs can be steered to a specified endpoint.
ROUTE_BY_IP
IP Prefix-based steering policies enable customers to steer DNS traffic based on the IP Prefix of the originating query.
