NEW QUESTION 23
Which two statements are true regarding cloning a block volume?
- A. You can change the block volume performance when creating a clone
- B. You can skip block volume encryption when creating a clone
- C. You can clone block volumes across regions
- D. You can change the block volume size when creating a clone
Answer: A,D
Explanation:
Explanation
Youcan 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 copyof 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 volumebetween 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 specifythe 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.
NEW QUESTION 24
You are the Solutions Architect of a large company and are tasked with migrating all your services to Oracle Cloud Infrastructure. As part of this, you first design a Virtual Cloud Network (VCN) with a public subnet and a private subnet. Then in order to provide Internet connectivity to the instances in your private subnet, you create an Oracle Linux instance in your public subnet and configure NAT on it. However, even after adding all related security list rules and routes in the Route Table, your private subnet instances still cannot connect to the Internet.
Which action should you perform to enable Internet connectivity?
- A. Create a Dynamic Routing Gateway (DRG) and route your private IP traffic to the DRG.
- B. There is no way that a private subnet can connect to the Internet.
- C. Restart the NAT instance.
- D. Disable "Source and Destination Check" on the VNIC of your Linux instance.
Answer: D
Explanation:
Explanation
https://docs.cloud.oracle.com/iaas/Content/Network/Tasks/managingVNICs.htm#Source/D By default, every VNIC performs the source/destination check on its network traffic. The VNIC looks at the source and destination listed in the header of each network packet. If the VNIC is not the source or destination, then the packet is dropped.
If the VNIC needs to forward traffic (for example, if it needs to perform Network Address Translation (NAT)), you must disable the source/destination check on the VNIC. For instructions, see To update an existing VNIC.
For information about the general scenario, see Using a Private IP as a Route Target.

You can move mount targets from one compartment to another.
NEW QUESTION 31
You are managing a tier-1 OLTP application on an Autonomous Transaction Processing (ATP) database. Your business needs to run hourly batch processes on this ATP database that may consume more CPUs than what isavailable on the server.
How can you limit these batch processes to not interfere with the OLTP transactions?
- A. Disable automated backup during the batch process operations.
- B. ATP is designed for OLTP workload only, you cannot run batch processes on ATP.
- C. Copy OLTP data into new tablesin a new table space and run batch processes against these new tables.
- D. Configure ATP resource management rules to change CPU/IO shares for the consumer group of batch processes.
Answer: D
Explanation:
Explanation
Autonomous TransactionProcessing comes with predefined CPU/IO shares assigned to different consumer groups. You can modify these predefined CPU/IO shares if your workload requires different CPU/IO resource allocations.
By default, the CPU/IO shares assigned to the consumer groups TPURGENT, TP, HIGH, MEDIUM, and LOW are 12, 8, 4, 2, and 1, respectively. The shares determine how much CPU/IO resources a consumer group can use with respect to the other consumer groups. With the default settings the consumer group TPURGENT will be able to use 12 times more CPU/IO resources compared to LOW, when needed. The consumer group TP will be able to use 4 times more CPU/IO resources compared to MEDIUM, when needed.
NEW QUESTION 32
Which statement is true about OracleCloud Infrastructure FastConnect?
- A. The FastConnect provider network offers only 1 Gbps port connection speed increments
- B. For private peering, FastConnect extends your existing infrastructure toa virtual cloud network
- C. For private peering, FastConnect extends your existing infrastructure to allow you to consume object storage from your on-premises data center
- D. For public peering, a dynamic routing gateway must be configured and attached to the virtual cloud network (VCN)
Answer: B
Explanation:
Explanation
With FastConnect, you can choose to use , or both.
Private peering: To extend your existing infrastructure into a virtual cloud network (VCN) in Oracle Cloud Infrastructure (for example, to implement a hybrid cloud, or a lift and shift scenario). Communication across the connection is with IPv4 private addresses (typically RFC 1918).
Public peering: To access public services in Oracle Cloud Infrastructure without using the internet. For example, Object Storage, the Oracle Cloud InfrastructureConsole and APIs, or public load balancers in your VCN. Communication across the connection is with IPv4 public IP addresses. Without FastConnect, the traffic destined for public IP addresses would be routed over the internet.
NEW QUESTION 33
Acompany currently uses Microsoft Active Directory as its identity provider. The company recently subscribed to Oracle Cloud Infrastructure (OCI) to leverage the cloud platform for test and development. As the administrator, you configured the OCI tenancy to be federated with Microsoft Active Directory. Now you need to give access to developers so that they can start creating resources in their OCI accounts.
Which step will you perform to make sure you are not duplicating user creation inside of OCI tenancy?
- A. Create a group for developers on OCI, export all the developers from Microsoft Active Directory, and then import them into the Identity and Access Management (IAM) group.
- B. Create a new user account in OCI for each user, and then create policies to provide access to developers.
- C. Create a single user account in OCI, and then create policies to provide access to developers to this single account.
- D. Create a group for developers on OCI and map the group to a similar group in Microsoft Active Directory during the federation process.
Answer: D
Explanation:
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 ofgroups (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.
NEW QUESTION 34

NEW QUESTION 37
Which two statements define the types of DNS resolvers that exist? (Choose two.)
- A. 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.
- B. A VCN resolverallows instances to use host names to communicate with instances on other VCNs in your tenancy.
- C. An Internet resolver allows instances to use the host names that are published on the Internet.
- D. 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.
Answer: C,D
Explanation:
Explanation
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 theinternet. 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.

NEW QUESTION 38
You have an application deployed in Oracle Cloud Infrastructure running only in the Phoenix region. You were asked to create a disaster recovery (DR)plan that will protect against the loss of critical data. The DR site must be at least 500 miles from your primary site and data transfer between the two sites must not traverse the public Internet.
Which is the recommended disaster recovery plan?
- A. Create a DR environment in Ashburn. Associate a DRG with the VCN in each region and create a remote peering connection between the two VCNs.
- B. Create a DR environment in Ashburn and provision a FastConnect virtual circuit using DRG between the regions.
- C. Create a new virtual cloud network (VCN) in the Phoenix region and create a subnet in one availability domain (AD) that is not currently being used by your production systems. Establish VCN peering between the production and DR sites.
- D. Create a DR environment in Ashburn. Associate a dynamic routing gateway (DRG) with the VCN in each region and configure an IPsec VPN connection between the two regions.
Answer: A
Explanation:
Explanation
Remote VCN peering is the process of connecting two VCNs in different regions (but the same tenancy ). The peering allows the VCNs' resources to communicate using private IP addresses without routing the traffic over the internet or through your on-premises network. Without peering, a given VCN would need an internet gateway and public IP addresses for the instances that need to communicate with another VCN in a different region.
At a high level, the Networking service components required for a remotepeering include:
- Two VCNs with non-overlapping CIDRs, in different regions that support remote peering. The VCNs must be in the same tenancy.
- A dynamic routing gateway (DRG) attached to each VCN in the peering relationship. Your VCN already has a DRG if you're using an IPSec VPN or an Oracle Cloud Infrastructure FastConnect private virtual circuit.
A remote peering connection (RPC) on each DRG in the peering relationship.
A connection between those two RPCs.
Supporting route rules to enable traffic to flow over the connection, and only to and from select subnets in the respective VCNs (if desired).
Supporting security rules to control the types of traffic allowed to and from the instances in the subnets that need to communicate with the other VCN.
NEW QUESTION 39
You are a network architect andhave designed the network infrastructure of a three-tier application on Oracle Cloud Infrastructure (OCI). In the architecture, back-end DB servers are in a private subnet. One of your DB administrators requests to have access to OCI object storage service.
How can you meet this requirement?
- A. Create a service gateway, add a new route rule to the private subnet route table that uses object storage as target type.
- B. Create a dynamic routing gateway (DRG) and attach it to your virtual cloud network (VCN). Add a default route rule to the private subnets route table and set the target as DRG.
- C. Attach a public IP address to the instances in the private subnet, and then add a new route rule to the private subnet route table to route default traffic to the internet gateway.
- D. Add a new route rule to the private subnet route table to route default traffic to the internet gateway.
Answer: A
Explanation:
Explanation
A service gateway lets resources in your VCN privately access specific Oracle services, without exposing the data to aninternet gateway or NAT. The resources in the VCN can be in a private subnet and use only private IP addresses. The traffic from the VCN to the service of interest travels over the Oracle network fabric and never traverses the internet.
To give your VCN access to a given service CIDR label, you must enable that service CIDR label for the VCN's service gateway. You can do that when you create the service gateway, or later after it's created. You can also disable a service CIDR label for the service gateway at any time.
For traffic to be routed from a subnet in your VCN to a service gateway, you must add a rule accordingly to the subnet's route table. The rule must use the service gateway as the target.
