NEW QUESTION # 83
You are designing a networking infrastructure in multiple Oracle Cloud Infrastructure regions and require connectivity between workloads in each region. You have created a dynamic routing gateway (DRG) and a remote peering connection. However, your workloads are unable to communicate with each other.
What are two reasons for this? (Choose two.)
- A. A local peering gateway needs to be created in each VCN with a default route rule added in the route table forwarding the traffic to the local peering gateway
- B. An Internet gateway needs to be created in each VCN with a default route rule added in the route table forwarding the traffic to the Internet Gateway
- C. Identity and Access Management (IAM) policies have not been defined to allow connectivity across the two VCNs in different regions
- D. The route table associated with subnets in each VCN do not have a route rule defined to forward the traffic to their respective DRGs
- E. The security lists associated with subnets in each virtual cloud network (VCN) do not have the appropriate ingress rules
Answer: D,E
Explanation:
Setting Up a Remote Peering
Create the RPCs: Each VCN administrator creates an RPC for their own VCN's DRG.
Share information: The administrators share the basic required information.
Set up the required IAM policies for the connection: The administrators set up IAM policies to enable the connection to be established.
Establish the connection: The requestor connects the two RPCs (see Important Remote Peering Concepts for the definition of the requestor and acceptor).
Update route tables: Each administrator updates their VCN's route tables to enable traffic between the peered VCNs as desired.
Update security rules: Each administrator updates their VCN's security rules to enable traffic between the peered VCNs as desired.

NEW QUESTION # 86
Which two statements are true about Oracle Cloud Infrastructure (OCI) DB Systems Data Guard service?
- A. Both DB systems must use the same VCN, and port 1521 must be open
- B. Data guard configuration on the OCI is limited to a virtual machine only
- C. Data guard implementation for Bare Metal shapes requires two DB Systems, one containing the primary database and one containing the standby database.
- D. Data guard implementation requires two DB Systems, one running the primary database on a virtual machine and the standby database running on bare metal.
Answer: A,C
Explanation:
An Oracle Data Guard implementation requires two DB systems, one containing the primary database and one containing the standby database. When you enable Oracle Data Guard for a virtual machine DB system database, a new DB system with the standby database is created and associated with the primary database. For a bare metal DB system, the DB system with the database that you want to use as the standby must already exist before you enable Oracle Data Guard.
Requirement details are as follows:
- Both DB systems must be in the same compartment.
- The DB systems must be the same shape type (for example, if the shape of the primary database is a virtual machine, then the shape of the standby database can be any other virtual machine shape).
- If your primary and standby databases are in different regions, then you must peer the virtual cloud networks (VCNs) for each database.
- Configure the security list ingress and egress rules for the subnets of both DB systems in the Oracle Data Guard association to enable TCP traffic to move between the applicable ports. Ensure that the rules you create are stateful (the default).

NEW QUESTION # 89
You are designing a two-tier web application in Oracle Cloud Infrastructure (OCI). Your clients want to access the web servers from anywhere, but want to prevent access to the database servers from the Internet.
Which is the recommended way to design the network architecture?
- A. Create public subnets for web servers and associate a dynamic routing gateway with that subnet, and a private subnet for database servers with no association to dynamic gateway.
- B. Create public subnets for web servers and private subnets for database servers in your virtual cloud network (VCN), and associate separate internet gateways for each subnet.
- C. Create public subnets for web servers and private subnets for database servers in your VCN, and associate separate security lists and route tables for each subnet.
- D. Create a single public subnet for your web servers and database servers, and associate only your web servers to internet gateway.
Answer: C
Explanation:
When you create a subnet, by default it's considered public, which means instances in that subnet are allowed to have public IP addresses. Whoever launches the instance chooses whether it will have a public IP address. You can override that behavior when creating the subnet and request that it be private, which means instances launched in the subnet are prohibited from having public IP addresses. Network administrators can therefore ensure that instances in the subnet have no internet access, even if the VCN has a working internet gateway, and security rules and firewall rules allow the traffic.
There are two optional gateways (virtual routers) that you can add to your VCN depending on the type of internet access you need:
Internet gateway: For resources with public IP addresses that need to be reached from the internet (example: a web server) or need to initiate connections to the internet.
NAT gateway: For resources without public IP addresses that need to initiate connections to the internet (example: for software updates) but need to be protected from inbound connections from the internet.
Just having an internet gateway alone does not expose the instances in the VCN's subnets directly to the internet. The following requirements must also be met:
The internet gateway must be enabled (by default, the internet gateway is enabled upon creation).
The subnet must be public.
The subnet must have a route rule that directs traffic to the internet gateway.
The subnet must have security list rules that allow the traffic (and each instance's firewall must allow the traffic).
The instance must have a public IP address.
NEW QUESTION # 90
Your organization has deployed a large, complex application across multiple compute instances in Oracle Cloud Infrastructure (OCI). These compute instances also have block volume storage attached to them. You want tocreate a time consistent backup of these block volume storage.
Which implementation strategy should be used?
- A. Use scripts available in OCI to backup block volume storage
- B. Create a manual backup of each volume
- C. Group volumes in a volume group firstand then use available scripts in OCI
- D. Group volumes in a volume group and create a manual backup of the volume group
Answer: D
Explanation:
Explanation
The Oracle Cloud Infrastructure Block Volume service provides you with the capability to group together multiple volumes ina volume group. A volume group can include both types of volumes, boot volumes, which are the system disks for your Compute instances, and block volumes for your data storage. You can use volume groups to create volume group backups and clones that are point-in-time and crash-consistent.
This simplifies the process to create time-consistent backups of running enterprise applications that span multiple storage volumes across multiple instances. You can then restore an entire group of volumes from a volume group backup.
To create a backup of the volume group
Open the navigation menu. Under Core Infrastructure, go to Block Storage and click Volumes Groups.
In the Volume Groups list, click Create Volume Group Backup in the Actions menu for the volume group you want to create a backup for.
