• Question 203:

  Which two statements define the types of DNS resolvers that exist? (Choose two.)

  A. A custom resolver allows instances to use the host names of the hosts in your on-prem network that are connected to your VCN by an IPSec VPN connection.
  B. A VCN resolver allows instances to use the host names of the hosts in your on-prem network that are connected to your VCN by an IPSec VPN connection.
  C. A VCN resolver allows instances to use host names to communicate with instances on other VCNs in your tenancy.
  D. An Internet resolver allows instances to use the host names that are published on the Internet.
  A. A custom resolver allows instances to use the host names of the hosts in your on-prem network that are connected to your VCN by an IPSec VPN connection.
  D. An Internet resolver allows instances to use the host names that are published on the Internet.

  https://docs.cloud.oracle.com/iaas/Content/Network/Concepts/dns.htm This is an Oracle-provided option that includes two parts: Internet Resolver: Lets instances resolve hostnames that are publicly published on the internet. The instances do not need to have internet access by way of either an internet gateway or a connection to your on-premises network (such as an IPSec VPN connection through a DRG ). VCN Resolver: Lets instances resolve hostnames (which you can assign) of other instances in the same VCN. For more information, see About the DNS Domains and Hostnames. By default, new VCNs you create use the Internet and VCN Resolver. If you're using the Networking API, this choice refers to the VcnLocalPlusInternet enum in the DhcpDnsOption object. The Internet and VCN Resolver does not let instances resolve the hostnames of hosts in your on- premises network connected to your VCN by IPSec VPN connection or FastConnect. Use your own custom DNS resolver to enable that. https://docs.cloud.oracle.com/iaas/Content/Network/Concepts/dns.htm?Highlight=DNS%20resolve r#About

• Question 204:

  Which three actions need to be performed before attempting a data transfer service job?

  A. Obtain an available host machine which can run the dts utility on-premise with SATA or USB drives attached for the transfer job.
  B. Get access to a high-speed internet connection
  C. Data Transfer Service and Storage Service Limits should be checked and raised if required.
  D. Set up SSH access to a host on OCI to coordinate the transfer job.
  E. Create an object bucket to receive the job.
  A. Obtain an available host machine which can run the dts utility on-premise with SATA or USB drives attached for the transfer job.
  C. Data Transfer Service and Storage Service Limits should be checked and raised if required.
  E. Create an object bucket to receive the job.

• Question 205:

  

  

  Which of the following two tasks can be performed in the Oracle Cloud Infrastructure Console for Autonomous Data Warehouse?

  A. Adjust Network Bandwidth
  B. Scale up/down Memory
  C. Increase Storage allocated for Database
  D. Scale up/down CPU
  C. Increase Storage allocated for Database
  D. Scale up/down CPU

  ---

  You can scale up/down your Autonomous Database to scale both in terms of compute (CPU) 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 in OCI console, 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 operating with auto scaling disabled.

• Question 206:

  You are designing a lab exercise for your team that has a large number of graphics with large file sizes. The application becomes unresponsive if the graphics are embedded in the application. You have uploaded the graphics to Oracle Cloud

  Infrastructure and only added the URL in the application. You need to ensure these graphics are accessible without requiring any authentication for an extended period of time.

  How can you achieve these requirements?

  A. Create pre-authenticated requests (PAR) and specify 00:00:0000 as the expiration time.
  B. Make the object storage bucket private and all objects public and use the URL found in the Object "Details".
  C. Make the object storage bucket public and use the URL found in the Object "Details".
  D. Create PARs and do not specify an expiration date.
  C. Make the object storage bucket public and use the URL found in the Object "Details".

  ---

  Pre-authenticated requests provide a way to let you access a bucket or an object without having your own credentials. For example, you can create a request that lets you upload backups to a bucket without owning API keys.

  When you create a bucket, the bucket is considered a private bucket and the access to the bucket and bucket contents requires authentication and authorization. However, Object Storage supports anonymous, unauthenticated access to a

  bucket. You make a bucket public by enabling read access to the bucket.

  pre-authenticated requests have to select expiration date

  

• Question 207:

  You have provisioned an Autonomous Transaction Processing (ATP) database and logged into the ATP service console. What are three abilities that can be performed from this service console? (Choose three.)

  A. scale up/down the CPUs
  B. create ATP database users
  C. reset the admin password
  D. set resource management rules
  E. monitor database activity and SQL queries
  C. reset the admin password
  D. set resource management rules
  E. monitor database activity and SQL queries

  ---

  In ATP Service Console,

  In the activity screen allows you to perform some basic monitor database activity and SQL queries

  

  In the administration screen allows you to perform some basic administration of the service, like reset the admin password and set resource management rules

  

• Question 208:

  You are implementing Oracle Cloud Infrastructure (OCI) FastConnect to access OCI public access points (e.g. ?object storage). You want other Internet traffic from your on-premises environment to use your existing connection with your ISP. What is the correct way to establish OCI FastConnect to access these OCI public endpoints?

  A. Configure private peering on your FastConnect link. Redistribute BGP routes learned into your existing routing table and advertise a default from your network infrastructure to OCI.
  B. Configure private peering on your FastConnect link with a static route that points to OCI object storage service.
  C. Configure public peering on your FastConnect link with a static route that points to OCI object storage service.
  D. Configure public peering on your FastConnect link. Redistribute BGP routes learned into your existing routing table and advertise a specific route for your network infrastructure to OCI.
  D. Configure public peering on your FastConnect link. Redistribute BGP routes learned into your existing routing table and advertise a specific route for your network infrastructure to OCI.

• Question 209:

  You are deploying a highly available web application In Oracle Cloud Infrastructure and have decided to use a public load balancer. The back-end web servers will be distributed across all three availability domains (ADs). How many subnets should you create to deliver a secure, highly available application?

  A. two subnets in total; one regional private subnet to host your back-end web servers and one regional public subnet to host your public load load balancer.
  B. two subnets in total; one regional public subnet to host your back-end web servers and one regional private subnet to host your public load load balancer.
  C. three subnets in total; one regional public subnet to host your back-end web servers and two AD specific private subnets to host your private load load balancer.
  D. one subnet in total; one regional private subnet to host your back-end web servers and your public load balancer.
  A. two subnets in total; one regional private subnet to host your back-end web servers and one regional public subnet to host your public load load balancer.

  ---

  To accept traffic from the internet, you create a public load balancer. The service assigns it a public IP address that serves as the entry point for incoming traffic. You can associate the public IP address with a friendly DNS name through any DNS vendor. A public load balancer is regional in scope. If your region includes multiple availability domains, a public load balancer requires either a regional subnet (recommended) or two availability domain- specific (AD-specific) subnets, each in a separate availability domain. With a regional subnet, the Load Balancing service creates a primary load balancer and a standby load balancer, each in a different availability domain, to ensure accessibility even during an availability domain outage. If you create a load balancer in two AD-specific subnets, one subnet hosts the primary load balancer and the other hosts a standby load balancer. If the primary load balancer fails, the public IP address switches to the secondary load balancer. The service treats the two load balancers as equivalent and you cannot specify which one is "primary". Whether you use regional or AD-specific subnets, each load balancer requires one private IP address from its host subnet. The Load Balancing service supplies a floating public IP address to the primary load balancer. The floating public IP address does not come from your backend subnets. You cannot specify a private subnet for your public load balancer. The backend servers (Compute instances) associated with a backend set can exist anywhere, as long as the associated network security groups (NSGs), security lists, and route tables allow the intended traffic flow. Oracle recommends that you create your load balancer in a regional subnet. Oracle recommends that you distribute your backend servers across all availability domains within the region.

• Question 210:

  When deploying a highly available, Internet-facing, 2-tier web application on Oracle Cloud Infrastructure (OCI), which design option would you use?

  A. Deploy all web servers into one Availability Domain and behind a public load balancer, and deploy two single-node OCI database systems in the same Availability Domain with Data Guard enabled.
  B. Deploy all web servers into multiple Availability Domains and behind a public load balancer, and deploy two single-node OCI database systems across two Availability Domains with Data Guard enabled.
  C. Deploy all web servers into multiple Availability Domains and behind a private load balancer, and deploy two single-node OCI database systems across two Availability Domains with Data Guard enabled.
  D. Deploy all web servers into one Availability Domain, and deploy a single-node OCI database system into a different Availability Domain.
  B. Deploy all web servers into multiple Availability Domains and behind a public load balancer, and deploy two single-node OCI database systems across two Availability Domains with Data Guard enabled.
