• Question 222:

  You are running an online gaming application hosted on a VM.Standard2.1 instance shape in Oracle Cloud

  Infrastructure. As the game becomes popular, you identify network throughput as a bottleneck on your

  instance when uploading user data.

  Though you want to resolve the issue, you want to observe the demand for a week before adding new

  application instances.

  Which action is the most efficient way to resolve this issue?

  A. Add a secondary virtual network interface card (VNIC).

  B. Change shape of the instance to a higher network bandwidth instance.

  C. Delete the instance while preserving boot volume and spin up a new higher network bandwidth instance with this boot volume.

  D. Change the performance tier of attached block volume to High Performance.

  Correct Answer: B

• Question 223:

  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

  Correct Answer: AC

  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. https://docs.cloud.oracle.com/en-us/iaas/Content/Object/Tasks/usingmultipartuploads.htm

• Question 226:

  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.

  Correct Answer: D

• Question 227:

  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.

  Correct Answer: C

  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 228:

  You created a public subnet and an internet gateway in your virtual cloud network (VCN) of Oracle Cloud Infrastructure. The public subnet has an associated route table and security list. However, after creating several compute instances in the public subnet, none can reach the Internet. Which two are possible reasons for the connectivity issue? (Choose two.)

  A. The route table has no default route for routing traffic to the internet gateway.

  B. There is no stateful egress rule in the security list associated with the public subnet.

  C. There is no dynamic routing gateway (DRG) associated with the VCN.

  D. There is no stateful ingress rule in the security list associated with the public subnet.

  E. A NAT gateway is needed to enable the communication flow to internet.

  Correct Answer: AB

  An internet gateway as an optional virtual router that connects the edge of the VCN with the internet. To use the gateway, the hosts on both ends of the connection must have public IP addresses for routing. Connections that originate in your VCN and are destined for a public IP address (either inside or outside the VCN) go through the internet gateway. Connections that originate outside the VCN and are destined for a public IP address inside the VCN go through the internet gateway. Working with Internet Gateways You create an internet gateway in the context of a specific VCN. In other words, the internet gateway is automatically attached to a VCN. However, you can disable and re-enable the internet gateway at any time. Compare this with a dynamic routing gateway (DRG), which you create as a standalone object that you then attach to a particular VCN. DRGs use a different model because they're intended to be modular building blocks for privately connecting VCNs to your on-premises network. For traffic to flow between a subnet and an internet gateway, you must create a route rule accordingly in the subnet's route table (for example, destination CIDR = 0.0.0.0/0 and target = internet gateway). If the internet gateway is disabled, that means no traffic will flow to or from the internet even if there's a route rule that enables that traffic. For more information, see Route Tables. For the purposes of access control, you must specify the compartment where you want the internet gateway to reside. If you're not sure which compartment to use, put the internet gateway in the same compartment as the cloud network. For more information, see Access Control. You may optionally assign a friendly name to the internet gateway. It doesn't have to be unique, and you can change it later. Oracle automatically assigns the internet gateway a unique identifier called an Oracle Cloud ID (OCID). For more information, see Resource Identifiers. To delete an internet gateway, it does not have to be disabled, but there must not be a route table that lists it as a target.

  AS per compute instances can connect to the Internet so you use egress no ingress

• Question 229:
