in ADW, The tnsnames.ora file provided with the credentials zip file contains three database service names identifiable as high, medium, and low. The predefined service names provide different levels of performance and concurrency for Autonomous Data Warehouse. high: The High database service provides the highest level of resources to each SQL statement resulting in the highest performance, but supports the fewest number of concurrent SQL statements. Any SQL statement in this service can use all the CPU and IO resources in your database. The number of concurrent SQL statements that can be run in this service is 3, this number is independent of the number of OCPUs in your database. medium: The Medium database service provides a lower level of resources to each SQL statement potentially resulting a lower level of performance, but supports more concurrent SQL statements. Any SQL statement in this service can use multiple CPU and IO resources in your database. The number of concurrent SQL statements that can be run in this service depends on the number of OCPUs in your database. low: The Low database service provides the least level of resources to each SQL statement, but supports the most number of concurrent SQL statements. Any SQL statement in this service can use a single CPU and multiple IO resources in your database. The number of concurrent SQL statements that can be run in this service can be up to 300 times the number of OCPUs. The predefined service names provide different levels of performance and concurrency for Autonomous DB Choose whichever database service offers the best balance of performance and concurrency. Use the low database service name. to minimize the impact of their SQLs to by low consumer group

Correct Answer: A

On autonomous there's no patching needed. But on the regular DB Cloud services you need to patch the DB and the OS. During the creation on the OCDB the first DB is created automatically Oracle automatically takes care of Operating system Installation/Configuration, Grid Infrastructure, ASM diskgroup Creation/ Configuration , and database software Installation and first database on the DB System. that's all when Creating DB Systems. and then the customer responsible to apply the patches to the database and OS

You can scale up/down your Autonomous Database to scale both in terms of compute and storage only

when needed, allows people to pay per use.

Oracle allows you to scale compute and storage independently, no need to do it together. these scaling

activities fully online (no downtime required) in Details page Autonomous Database click Scale Up/Down.

Click on arrow to select a value for CPU Core Count or Storage (TB).

Or Select auto scaling to allow the system to automatically use up to three times more CPU and IO

resources to meet workload demand, compared to the database operating with auto scaling disabled.

Correct Answer: C

a policy statement must specify the compartment for which access is being granted (or the tenancy).

Where you create the policy determines who can update the policy. If you attach the policy to the

compartment or its parent, you can simply specify the compartment name. If you attach the policy further

up the hierarchy, you must specify the path. The format of the path is each compartment name (or OCID)

in the path, separated by a colon:

:: . . . For example, assume you

have a three-level compartment hierarchy, shown here:

You want to create a policy to allow NetworkAdmins to manage VCNs in CompartmentC. If you want to attach this policy to CompartmentC or to its parent, CompartmentB, write this policy statement: Allow group NewtworkAdmins to manage virtual-network-family in compartment CompartmentC However, if you want to attach this policy to CompartmentA (so that only administrators of CompartmentA can modify it), write this policy statement that specifies the path: Allow group NewtworkAdmins to manage virtual-network-family in compartment CompartmentB:CompartmentC To attach this policy to the tenancy, write this policy statement that specifies the path from CompartmentA to CompartmentC: Allow group NewtworkAdmins to manage virtual-network-family in compartment CompartmentA:CompartmentB:CompartmentC
