Question #16
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 the Oracle Cloud Infrastructure (OCI) 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?
  1. A
    Set up the FastConnect virtual circuit as your primary connection, and a second FastConnect virtual circuit as a backup connection. Make sure your FastConnect physical connectivity is redundant. Use a single edge device in your on-premises data center for each connection. From your edge device, advertise more specific routes via the primary FastConnect virtual circuit, and less specific routes through the backup FastConnect virtual circuit.
  2. B
    Set up the 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. From your edge devices, advertise more specific routes through the FastConnect virtual circuit, and less specific routes through the backup IPSec VPN path.
  3. C
    Set up IPSec VPN as your primary connection, and a second IPSec VPN as a backup connection. Use separate edge devices in your on-premises data center for each connection. From your edge devices, advertise more specific routes via the primary IPSec VPN, and less specific routes through the backup IPSec VPN.
  4. D
    Set up IPSec VPN as your primary connection, and a FastConnect virtual circuit as a backup connection. Use separate edge devices in your on-premises data center for each connection. From your edge devices, advertise more specific routes through the IPSec VPN, and less specific routes through the backup FastConnect virtual circuit.

Correct Answer:
A

Question #17
An Oracle Cloud Infrastructure (OCI) Public Load Balancers SSL certificate is expiring soon. You notice that the Load Balancer is configured with SSL Termination only. When the certificate expires, data traffic can be interrupted and could compromise security.
What steps do you need to take to prevent this situation?
  1. A
    Add the new SSL certificate to the Load Balancer and implement end-to-end SSL so it can encrypt the traffic from clients all the way to the backend servers.
  2. B
    Add the new SSL certificate to the Load Balancer, update listeners and backend sets so they can use the new certificate bundle.
  3. C
    Add the new SSL certificate to the Load Balancer, update backend servers to work with a new certificate and edit listeners so they can use the new certificate bundle.
  4. D
    Add the new SSL certificate to the Load Balancer and update listeners to use the new certificate bundle.
  5. E
    Add the new SSL certificate to the Load Balancer and update backend servers to use the new certificate bundle.

Correct Answer:
D

Question #18
Your company has recently deployed a new web application that uses Oracle Functions. Your manager instructs you to implement monitoring metrics to manage your systems more effectively. You know that Oracle Functions automatically monitors functions on your behalf and reports metrics through Service Metrics.
Which TWO metrics are collected and made available by this feature? (Choose two.)
  1. A
    Length of time a function runs
  2. B
    Number of times a function is invoked
  3. C
    Amount of CPU used by a function
  4. D
    Number of concurrent connections
  5. E
    Number of times a function is removed

Correct Answer:
AB

Question #19
You are designing the network infrastructure for two application servers: appserver-1 and appserver-2 running in two different subnets inside the same Virtual Cloud Network (VCN) in Oracle Cloud Infrastructure (OCI). You have a requirement where your end users will access appserver-1 from the internet and appserver-2 from the on-premises network. The on-premises network is connected to your VCN over a FastConnect virtual circuit.
How should you design your routing configuration to meet these requirements?
  1. A
    Configure a single routing table (Route Table-1) that has two sets of rules: one that has route to internet via the Internet Gateway and another that propagates specific routes for the on-premise network via Dynamic Routing Gateway (DRG). Associate the routing table with the VCN.
  2. B
    Configure two routing tables: Route Table-1 that has a route to internet via the Internet gateway. Associate this route table to the subnet containing appserver-1. Route Table-2 that propagate specific routes for the on-premises network via the Dynamic Routing Gateway (DRG). Associate this route table to subnet containing appserver-2.
  3. C
    Configure a single routing table (Route Table-1) that has two sets of rules. One that has route to internet via the Internet Gateway and another that propagates specific routes for the on-premise network via the Dynamic Routing Gateway. Associate the routing table with all the VCN subnets.
  4. D
    Configure two routing tables (Route Table-1 & Route Table-2) that have rule to route all traffic via the Dynamic Routing Gateway (DRG). Associate the two routing tables with all the VCN subnets.

Correct Answer:
B

Question #20
To serve web traffic for a popular product, your cloud engineer has provisioned four BM.Standard2.52 instances, evenly spread across two availability domains in the us-ashburn-1 region; LoadBalancer is used to deliver the traffic across instances.
After several months, the product grows even more popular and you need additional compute capacity. As a result, an engineer provisioned two additional VM.Standard2.8 instances.
You register the two VM.Standard2.8 instances with your Load Balancer Backend set and quickly find that the VM.Standard2.8 instances are now running at 100% of CPU utilization but the BM.Standard2.52 instances have significant CPU capacity that's unused.
Which option is the most cost effective and uses instances capacity most effectively?
  1. A
    Configure LoadBalancer with two VM.Standard2.8 instances and use Autoscaling instance pool to add up to two additional VM.Standard2.8 instances. Shut off BM.Standard2.52 instances.
  2. B
    Configure your Load Balancer with weighted round robin policy to distribute traffic to the compute instances, with more weight assigned to bare metal instances.
  3. C
    Configure Autoscaling instance pool with LoadBalancer to add up to 3 more BM. Standard2.52 Instances when triggered, Shut off VM.Standard2.8 Instances.
  4. D
    Route traffic to BM.Standard2.52 and VM.Standard2.8 Instances directly using DNS and Health Checks. Shut off the Load Balancer.

Correct Answer:
B
