Oracle Cloud Infrastructure 2022 Architect Associate Sample Questions (Q95-Q100):

NEW QUESTION # 95
You created a public subnet and an internet gateway in your virtual cloud network (VCN) of Oracle Cloud Infrastructure. The public subnet has an associated route table and security list. However, after creating several compute instances in the public subnet, none can reach the Internet.
Which two are possible reasons for the connectivity issue? (Choose two.)

• A. A NAT gateway is needed to enable the communication flow to internet.
• B. There is no dynamic routing gateway (DRG) associated with the VCN.
• C. The route table has no default route forrouting traffic to the internet gateway.
• D. There is no stateful ingress rule in the securitylist associated with the public subnet.
• E. There is no stateful egress rule in the security list associated with the public subnet.

Answer: C,E Explanation:
Explanation
An internet gateway as an optional virtual router that connects the edge of the VCN with the internet. To use the gateway, the hosts on both ends of the connection must have public IP addresses for routing. Connections that originate in your VCN and are destined for a public IP address (either inside or outside the VCN) go through the internet gateway. Connections that originate outside the VCN and are destined for a public IP address inside the VCN go through the internet gateway.
Working with Internet Gateways
You create an internet gateway in the context of a specific VCN. In other words, the internet gateway is automatically attached to a VCN. However, you can disable and re-enable the internet gateway at any time.
Compare this with a dynamic routing gateway (DRG), which you create asa standalone object that you then attach to a particular VCN. DRGs use a different model because they're intended to be modular building blocks for privately connecting VCNs to your on-premises network.
For traffic to flow between a subnet and an internetgateway, you must create a route rule accordingly in the subnet's route table (for example, destination CIDR = 0.0.0.0/0 and target = internet gateway). If the internet gateway is disabled, that means no traffic will flow to or from the internet even if there's a route rule that enables that traffic. For more information, see Route Tables.
For the purposes of access control, you must specify thecompartment where you want the internet gateway to reside. If you're not sure which compartment to use, put the internet gateway in the same compartment as the cloud network. For more information, see Access Control.
You may optionally assign a friendly name to the internet gateway. It doesn't have to be unique, and you can change it later. Oracle automatically assigns the internet gateway a unique identifier called an Oracle Cloud ID (OCID). For more information, see Resource Identifiers.
To delete an internet gateway, it does not have to be disabled, but theremust not be a route table that lists it as a target.
AS per compute instances can connect to the Internet so you use egress no ingress
NEW QUESTION # 96
Which two options are true for Autonomous Transaction Processing (ATP) database? (Choose two.)

• A. You can scale CPU up or down in ATP
• B. You canadd more Pluggable Database for consolidating multiple databases in ATP
• C. You can scale storage up or down in ATP
• D. You can add/remove Diskgroup in ATP
• E. You can add new ORACLE_HOME for bringing older versions of on-premises databases to ATP

Answer: A,C Explanation:
Explanation
You can scale up/down your Autonomous Database to scale both in terms ofcompute 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 operatingwith auto scaling disabled.
NEW QUESTION # 97
You have an application deployed in Oracle Cloud Infrastructure running only in the Phoenix region. You were asked to create a disaster recovery (DR) plan that will protect against the loss of critical dat a. The DR site must be at least 500 miles from your primary site and data transfer between the two sites must not traverse the public Internet.
Which is the recommended disaster recovery plan?

• A. Create a DR environment in Ashburn. Associate a dynamic routing gateway (DRG) with the VCN in each region and configure an IPsec VPN connection between the two regions.
• B. Create a DR environment in Ashburn and provision a FastConnect virtual circuit using DRG between the regions.
• C. Create a new virtual cloud network (VCN) in the Phoenix region and create a subnet in one availability domain (AD) that is not currently being used by your production systems. Establish VCN peering between the production and DR sites.
• D. Create a DR environment in Ashburn. Associate a DRG with the VCN in each region and create a remote peering connection between the two VCNs.

Answer: D Explanation:
Remote VCN peering is the process of connecting two VCNs in different regions (but the same tenancy ). The peering allows the VCNs' resources to communicate using private IP addresses without routing the traffic over the internet or through your on-premises network. Without peering, a given VCN would need an internet gateway and public IP addresses for the instances that need to communicate with another VCN in a different region.
At a high level, the Networking service components required for a remote peering include:
- Two VCNs with non-overlapping CIDRs, in different regions that support remote peering. The VCNs must be in the same tenancy.
- A dynamic routing gateway (DRG) attached to each VCN in the peering relationship. Your VCN already has a DRG if you're using an IPSec VPN or an Oracle Cloud Infrastructure FastConnect private virtual circuit.
A remote peering connection (RPC) on each DRG in the peering relationship.
A connection between those two RPCs.
Supporting route rules to enable traffic to flow over the connection, and only to and from select subnets in the respective VCNs (if desired).
Supporting security rules to control the types of traffic allowed to and from the instances in the subnets that need to communicate with the other VCN.

NEW QUESTION # 98
Which three are capabilities of the dbaascli utility? (Choose three.)

• A. Switchover and failover in an Oracle Guard configuration
• B. Start and open the database instance
• C. Open port 1521 in the VCN to allow for traffic to the listener
• D. Patching the primary database deployment
• E. Clone a DB

Answer: A,B,D Explanation:
Explanation
https://docs.oracle.com/en/cloud/paas/database-dbaas-cloud/csdbi/dbaascli.html Using the dbaascli utility, you can:
Change the password of a database user.
Start and stop a database.
Start and stop the Oracle Net listener

NEW QUESTION # 99
You need to set up instance principals so that an application running on an instance can call Oracle Cloud Infrastructure (OCI) public services, without the need to configure user credentials.
A developer in your team has already configured the application built using an OCI SDK to authenticate using the instance principals provider.
Which is NOT a necessary step to complete this set up?

• A. Create a policy granting permissions to the dynamic group to access services in your compartment or tenancy.
• B. Create a dynamic group with matching rules to specify which instances you want to allow to make API calls against services.
• C. Generate Auth Tokens to enable instances in the dynamic group to authenticate with APIs.
• D. Deploy the application and the SDK to all the instances that belong to the dynamic group.

Answer: D
