You have an Oracle Cloud Infrastructure (OCI) load balancer distributing traffic via an evenly-
weighted round robin policy to your back-end web servers. You notice that one of your web servers is
receiving more traffic than other web servers.
How can you resolve this to make sure traffic is evenly distributed across all back-end webservers?

You need to set up instance principals so that an application running on an instance can call Oracle
Cloud Infrastructure (OCI) public services, without the need to configure user credentials.
A developer in your team has already configured the application built using an OCI SDK to
authenticate using the instance principals provider.
Which is NOT a necessary step to complete this set up?

You work for a health insurance company that stores a large number of patient health records in an
Oracle Cloud Infrastructure (OCI) Object Storage bucket named "HealthRecords".
Each record needs to be securely stored for a period of 5 years for regulatory compliance purposes
and
cannot be modified, overwritten or deleted during this time period.
What can you do to meet this requirement?

A financial firm is designing an application architecture for its online trading platform that must have
high availability and fault tolerance.
Their solutions architect configured the application to use an Oracle Cloud Infrastructure Object
Storage bucket located in the US West (us-phoenix-1) region to store large amounts of financial dat
a. The stored financial data in the bucket must not be affected even if there is an outage in one of the
Availability Domains or a complete region.
What should the architect do to avoid any costly service disruptions and ensure data durability?

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.)
AB
Explanation:
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 thenattachto 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
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?
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,unauthenticatedaccess to a bucket. You make a bucketpublicby enabling read access
to the bucket.
pre-authenticated requests have to select expiration date
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.
