Question 2 Single choice

A data analytics company has been building Its now generation big data and analytics platform on Oracle Cloud Infrastructure (OCI). They need a storage service that provide the scale and performance that their big data applications require such as high throughput to compute nodes with low latency file operations in addition, their data needs to be stored redundantly across multiple nodes In a single availability domain and allows concurrent connections from multiple compute Instances hosted on multiple availability domains.

Which OCI storage service can you use to meet i his requirement?

A
Object Storage
B
File System Storage
C
Archive storage
D
Block Volume

Show answer and explanation

Correct answer: B

Explanation

Oracle Cloud Infrastructure File Storage service provides a durable, scalable, secure, enterprise-grade network file system. You can connect to a File Storage service file system from any bare metal, virtual machine, or container instance in your Virtual Cloud Network (VCN). You can also access a file system from outside the VCN using Oracle Cloud Infrastructure FastConnect and Internet Protocol security (IPSec) virtual private network (VPN).
Use the File Storage service when your application or workload includes big data and analytics, media processing, or content management, and you require Portable Operating System Interface (POSIX)- compliant file system access semantics and concurrently accessible storage. The File Storage service is designed to meet the needs of applications and users that need an enterprise file system across a wide range of use cases

Question 4 Multiple choice

You have deployed a web application targeting a global audience across multiple Oracle Cloud Infrastructure (OCI) regions.

You decide to use Traffic Management Geo-Location based Steering Policy to serve web requests to users from the region closets to the user. Within each region you have deployed a public load balancer with 4 servers in a backend set. During a DR test disable all web servers in one of the regions however, traffic Management does not automatically direct all users to the other region.

Which two are possible causes?

A
You did not setup a Route Table associated with load Balancer's subnet
B
You did not setup an HTTP Health Check associated with Load Balancer public IP in the disabled region.
C
Rather than using Geo-Location based Steering Policy, you should use Failover Policy Type to serve traffic.
D
One of the two working web servers In the other region did not pass Its HTTP health check
E
You did not correctly setup the Load Balancer HTTP health check policy associated with backend set

Show answer and explanation

Correct answers: B, E

Explanation

Managing Traffic Management GEOLOCATION Steering Policies Geolocation steering policies distribute DNS traffic to different endpoints based on the location of the end user. Customers can define geographic regions composed of originating continent, countries or states/provinces (North America) and define a separate endpoint or set of endpoints for each region.
The Health Checks service allows you to monitor the health of IP addresses and hostnames, as measured from geographic vantage points of your choosing, using HTTP and ping probes. After configuring a health check, you can view the monitor's results. The results include the location from which the host was monitored, the availability of the endpoint, and the date and time the test was performed. Also you can Combine Managing Traffic Management GEOLOCATION Steering Policies with Oracle Health Checks to fail over from one region to another The Load Balancing service provides health status indicators that use your health check policies to report on the general health of your load balancers and their components. if you misconfigure the health check Protocol between the Load balancer and backend set that can lead to not get an accurate response as example below If you run a TCP-level health check against an HTTP service, you might not get an accurate response. The TCP handshake can succeed and indicate that the service is up even when the HTTP service is ly configured or having other issues. Although the health check appears good customers might experience transaction failures.

Question 5 Single choice

You are a solution architect working with a startup that has decided to move their workload to Oracle Cloud Infrastructure. Since their workload is small, upon architecting, you decide its sufficient to use 8 compute instances to run their workload. The company wants to use a common storage for their instances. So, you propose the idea of attaching a block volume to multiple instances to provide a common storage.

Which of the below option is NOT true for such a solution?

A
If the block volume is already attached to an instance as read/write non-shareable you can't attach it to another instance until you detach it from the first instance.
B
Block volumes attached as read-only are configured as shareable by default.
C
You can delete a block volume from one instance without detaching it from all other instances there by
keeping other instance's storage intact.
D
Once you attach a block volume to an instance as read-only, it can only be attached to other instances as read-only.

Question 7 Single choice

A retail company has recently adopted a hybrid architecture. They have the following requirements for their end-to-end Connectivity model between their on-premises data center and Oracle Cloud Infrastructure (OC1) region

* Highly available connection with service level redundancy

* Dedicated network bandwidth with low latency

Which connectivity setup is the most cost effective solution for this scenario?

A
Setup IPsec VPN as your primary connection, and a FastConnect virtual circuit as a backup connection. Use separate edge devices in your on-premises data canter for each connection from your edge devices, advertise more specific routes IPSec VPN, and specific routes through the backup FastConnect virtual circuit.

Setup FastConnect virtual circuit as your primary connection, and a second FastConnect virtual circuit as a backup connection. Use separate edge devices in your FastConnect physical connectivity is redundant Use a single edge device in your on premises data center for each connection From yc device, advertise more specific routes via primary FastConnect virtual circuit, and less specific routes through t backup FastConnect circuit.
C
Setup FastConnect virtual circuit as your primary connection, and an IPSec VPN as a backup connection. Use separate edge devices in your on-premises data center for each connection.
