• Question 55:

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

  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.

• Question 56:

  Which two resources reside exclusively in a single Oracle Cloud Infrastructure Availability Domain? (Choose two.)

  A. Identity and Access Management Groups
  B. Object Storage
  C. Web Application Firewall policy
  D. Block volume
  E. Compute instance
  D. Block volume
  E. Compute instance

  ---

  Availability Domain-Specific Resources DB Systems ephemeral public IPs instances: They can be attached only to volumes in the same availability domain. subnets: When you create a subnet, you choose whether it is regional or specific to an availability domain. Oracle recommends using regional subnets. volumes: They can be attached only to an instance in the same availability domain.

• Question 57:

  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 private subnets for database servers in your virtual cloud network (VCN), and associate separate internet gateways for each subnet.
  B. 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.
  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.
  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.

  ---

  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.

• Question 58:

  Which two choices are true for Oracle Autonomous Database with Shared Exadata Infrastructure?

  A. Billing for storage usage continues when autonomous database is stopped.
  B. Billing stops for both CPU and storage usage when autonomous database is stopped.
  C. Billing for compute usage stops when autonomous database is stopped.
  D. Autonomous database does not support per-second billing.
  E. Billing does not stop when autonomous database is terminated.
  A. Billing for storage usage continues when autonomous database is stopped.
  C. Billing for compute usage stops when autonomous database is stopped.

• Question 59:

  Which is a customer's responsibility on an Oracle Cloud Infrastructure database?

  A. patching the database and OS
  B. creating the first default database on the DBCS server
  C. creating an ASM diskgroup for data file or temp file storage
  D. installing the operating system (OS), Grid Infrastructure, and database software
  A. patching the database and OS

  ---

  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

• Question 60:

  B. Oracle Identity Cloud Services
  C. AWS Directory Services
  D. Google Directory Federation Services
  A. Microsoft Active Directory
  B. Oracle Identity Cloud Services

  ---

  References:

  Oracle Cloud Infrastructure supports federation with Oracle Identity Cloud Service and Microsoft Active Directory (via Active Directory Federation Services (AD FS)), and any identity provider that supports the Security Assertion Markup

  Language (SAML) 2.0 protocol.
