Free Oracle 1Z0-1072-22 Exam Questions

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.)

  1. The security lists associated with subnets in each virtual cloud network (VCN) do not have the appropriate ingress rules
  2. Identity and Access Management (IAM) policies have not been defined to allow connectivity across the two VCNs in different regions
  3. 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
  4. 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
  5. The route table associated with subnets in each VCN do not have a route rule defined to forward the traffic to their respective DRGs

Answer(s): A,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.



Which two statements below are correct with respect to adding secondary Virtual Network Interface Cards (VNICs) to an existing compute instance in Oracle Cloud Infrastructure? (Choose two.)

  1. The secondary VNIC is required to be in the same Virtual Cloud Network (VCN), but can be in different
    subnet, as the primary VNIC.
  2. The primary and secondary VNIC association can be in different virtual cloud networks (VCNs).
  3. You cannot assign an Ephemeral Public IP to a secondary VNI
  4. The primary and secondary VNIC association must be in the same availability domain.
  5. You can remove the primary VNIC after the secondary VNIC's attachment is complete.

Answer(s): B,D

Explanation:

“You can add secondary VNICs to an instance after it’s launched. Each secondary VNIC can be in a subnet in the same VCN as the primary VNIC, or in a different subnet that is either in the same VCN or a different one. However, all the VNICs must be in the same availability domain as the instance.” https://docs.cloud.oracle.com/en-us/iaas/Content/Network/Tasks/managingVNICs.htm



You provisioned an Oracle Autonomous Data Warehouse (ADW) on Oracle Cloud Infrastructure (OCI) and imported data into ADW.

You want to give your business analyst the ability to connect to the ADW database and run queries. Which two actions can help you meet this requirement? (Choose two.)

  1. Create a database user account for the business analyst.
  2. Grant the predefined database role DWROLE to the database user.
  3. Grant unlimited tablespace privilege to the database user.
  4. Grant the predefined database role DWADW to the database user.
  5. Grant the predefined database role DWUSER to the database user.

Answer(s): B,C

Which statement is true about interconnecting Virtual Cloud Network (VCN)?

  1. VCNs support transitive peering.
  2. Peering VCNs should not have overlapping CIDR blocks.
  3. VCNs must be in the same tenancy to be peered.
  4. The only way to interconnect VCNs is through peering.

Answer(s): B
