NEW QUESTION 93
A customer has launched a compute Instance in the Virtual Cloud Network (VCN), which has an Internet gateway, a service gateway, a default security lists and a default route table. Customer has opened up Port 22 in the security lists attached to the compute instance subnet, however is still unable to connect to compute instances using ssh.
Which option would remedy this situation?
- A. Modify the route table associated with the VCN subnet in which the instance resides. Add a following route to the route table.
Destination CIDR: 0.0.0.0/0
Target: Internet Gateway (IGW) - B. Modify the security list associated with the VCN subnet in which the instance resides. Add a stateful egress rule to allow icmp traffic in addition to the port 22.
- C. Modify the route table associated with the VCN subnet in which the instance resides. Add a following route to the route table.
Destination CIDR: 0.0.0.0/0
Target: Dynamic Routing Gateway (DRG) - D. Modify the route table associated with the VCN subnet in which the instance resides. Add a following route to the route table.
Destination CIDR: 0.0.0.0/0
Target: Service Gateway (SGW)
Answer: A
Explanation:
Explanation
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.
For traffic to flow between a subnet and an internet gateway, 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 the purposes of access control, you must specify the compartment 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.

You have successfully configured identity federation between Oracle Cloud Infrastructure (OCI) and Oracle Identity Cloud Services (IDCS). A new project manager wants access to OCI for her team and provides the name of an existing group within IDCS to use when granting access.
How do you configure federation to allow the project team access to OCI resources?
- A. Create a new IAM group in OCI and map it to the existing IDCS group. Create a new policy in IDCS and reference the name of the IAM group.
- B. Create a new Identity and Access Management (IAM) policy in OCI and reference the name of the IDCS group in each policy statement.
- C. Create a new IAM group in OCI and map it to the existing IDCS group. Create a new IAM policy and reference the name of the IAM group in each policy statement.
- D. Create a new compartment in OCI with the same name as the existing IDCS group. Create an IAM policy that references the new compartment and the name of the IDCS group.
Answer: C
Explanation:
When working with your IdP, your administrator defines groups and assigns each user to one or more groups according to the type of access the user needs. Oracle Cloud Infrastructure also uses the concept of groups (in conjunction with IAM policies) to define the type of access a user has. As part of setting up the relationship with the IdP, your administrator can map each IdP group to a similarly defined IAM group, so that your company can re-use the IdP group definitions when authorizing user access to Oracle Cloud Infrastructure resources. Here's a screenshot from the mapping process:

NEW QUESTION 105
Which two statements are true regarding cloning a block volume?
- A. You can change the block volume size when creating a clone
- B. You can clone block volumes across regions
- C. You can skip block volume encryption when creating a clone
- D. You can change the block volume performance when creating a clone
Answer: A,D
Explanation:
Explanation
You can create a clone from a volume using the Block Volume service. Cloning enables you to make a copy of an existing block volume without needing to go through the backup and restore process.
A cloned volume is a point-in-time direct disk-to-disk deep copy of the source volume, so all the data that is in the source volume when the clone is created is copied to the clone volume.
You can only create a clone for a volume within the same region, availability domain and tenant. You can create a clone for a volume between compartments as long as you have the required access permissions for the operation.
during create a clone you can do the following
If you want to clone the block volume to a larger size volume, check Custom Block Volume Size (GB) and then specify the new size. You can only increase the size of the volume, you cannot decrease the size. If you clone the block volume to a larger size volume, you need to extend the volume's partition. See Extending the Partition for a Block Volume for more information.
If you want to change the elastic performance setting when cloning the volume, check Custom Block Volume Performance and select the elastic performance setting you want the volume clone to use. See Block Volume Elastic Performance for more information. You can also change the elastic performance setting after you have cloned the volume, see Block Volume Elastic Performance. If you leave Custom Block Volume Performance unchecked, the cloned volume will use the same elastic performance setting as the source volume.
