NEW QUESTION 7

You are about to upload log file (5 TiB size) to Oracle Cloud Infrastructure object storage and have decided to use multipart upload capability for a more efficient and resilient upload.
Which two statements are true about multipart upload? (Choose two.)

• A. Individual object parts can be as small as 10 MiB or as large as 50 GiB
• B. While a multipart upload is still active, you cannot add parts even if the total number of parts is less than 10,000
• C. The maximum size for an uploaded object is 10 TiB
• D. You do not have to commit the upload after you have uploaded all the object parts

Answer: AC

Explanation:
With multipart upload, you split the object you want to upload into individual parts. Individual parts can be as large as 50 GiB or as small as 10 MiB. (Object Storage waives the minimum part size restriction for the last uploaded part.) Decide what part number you want to use for each part. Part numbers can range from 1 to 10,000. You do not need to assign contiguous numbers, but Object Storage constructs the object by ordering part numbers in ascending order.
The maximum size for an uploaded object is 10 TiB
While a multipart upload is still active, you can keep adding parts as long as the total number is less than 10,000.

NEW QUESTION 12

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.

Answer: A

Explanation:
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.

NEW QUESTION 13

NEW QUESTION 14

You have setup your environment as shown below with the Mount Target "MT" successfully mounted on both compute instances CLIENT-X and CLIENT-Y.
For security reasons you want to control the access to the File System A in such a way that CLIENT-X has READ/WRITE and CLIENT-Y has READ only permission.

What you should do?

• A. Update the OS firewall in CLIENT-X to allow READ/WRITE access.
• B. Update the security list TWO to restrict CLIENT-Y access to read-only.
• C. Update the mount target export options to restrict CLIENT-Y access to read-only.
• D. Update the security list ONE to restrict CLIENT-Y access to read only.

Answer: D

NEW QUESTION 15

When terminating a compute instance, which statement is true?

• A. The instance needs to be stopped first, and then terminated.
• B. The boot volume is always deleted.
• C. All block volumes attached to the instance are terminated.
• D. Users can preserve the boot volume associated with the instance.

Answer: D

Explanation:
You can permanently terminate (delete) instances that you no longer need. Any attached VNICs and volumes are automatically detached when the instance terminates. Eventually, the instance's public and private IP addresses are released and become available for other instances. By default, the instance's boot volume is deleted when you terminate the instance, however you can preserve the boot volume associated with the instance, so that you can attach it to a different instance as a data volume, or use it to launch a new instance.

NEW QUESTION 16

Which two statements are true about policies?

NEW QUESTION 20

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

Answer: AE

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 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.

NEW QUESTION 21

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.

Answer: C

Explanation:
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
