Oracle Cloud Infrastructure 2022 Architect Professional 1z0-997-22 Prüfungsfragen mit Lösungen (Q51-Q56):

51. Frage
You are building a highly available and fault tolerant web application deployment for your company. Similar application delayed by competitors experienced web site attack including DDoS which resulted in web server failing.
You have decided to use Oracle Web Application Firewall (WAF) to implement an architecture which will provide protection against such attacks and ensure additional configuration will you need to implement to make sure WAF is protecting my web application 24×7.
Which additional configuration will you need to Implement to make sure WAF Is protecting my web application 24×7?

  • A. Configure new rules based on now vulnerabilities and mitigations
  • B. Configure auto scaling policy and it to WAF instance.
  • C. Configure Control Rules to send traffic to multiple web servers
  • D. Configure multiple origin servers

Antwort: D

Origin Management
An origin is an endpoint (typically an IP address) of the application protected by the WAF. An origin can be an Oracle Cloud Infrastructure load balancer public IP address. A load balancer IP address can be used for high availability to an origin. Multiple origins can be defined, but only a single origin can be active for a WAF. You can set HTTP headers for outbound traffic from the WAF to the origin server. These name value pairs are then available to the application.
Oracle Cloud Infrastructure Web Application Firewall (WAF) is a cloud-based, Payment Card Industry (PCI) compliant, global security service that protects applications from malicious and unwanted internet traffic.
WAF can protect any internet facing endpoint, providing consistent rule enforcement across a customer’s applications. WAF provides you with the ability to create and manage rules for internet threats including Cross-Site Scripting (XSS), SQL Injection and other OWASP-defined vulnerabilities. Unwanted bots can be mitigated while tactically allowed desirable bots to enter. Access rules can limit based on geography or the signature of the request.
Distributed Denial of Service (DDoS)
A DDoS attack is an often intentional attack that consumes an entity’s resources, usually using a large number of distributed sources. DDoS can be categorized into either Layer 7 or Layer 3/4 (L3/4) A layer 7 DDoS attack is a DDoS attack that sends HTTP/S traffic to consume resources and hamper a website’s ability to delivery content or to harm the owner of the site. The Web Application Firewall (WAF) service can protect layer 7 HTTP-based resources from layer 7 DDoS and other web application attack vectors.

52. Frage
A developer is using Oracle Functions to deploy her code as part of an event-driven solution in Oracle Cloud Infrastructure (OCI). When she invokes her function, Oracle Functions returns a FunctionlnvokelmageNotAvailable message and a 502 error:

Which of the following options is NOT a plausible reason for this error?

  • A. OCI Events service rule is not configured with the correct location of the function in OCI Registry.
  • B. The VCN being used does not have an internet gateway or a service gateway configured for Oracle Functions to be able to access OCI Registry.
  • C. Missing or invalid IAM policy to give Oracle Functions read access to images stored for functions in repositories in OCI Registry.
  • D. The function does not exist in the specified location in OCI Registry.

Antwort: A

53. Frage
To serve web traffic for a popular product, your cloud engineer has provisioned four BM.Standard2.52 instances, event spread across two availability domains in the us-asburn-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 sot and quickly find that the VM Standard2.8 Instances 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?

  • A. Configure LoadBalancer with two VM Standard2.8 instances and use Autoscalling Instant pool to add up to two additional VM instances. Shut off BM.Standard2.52 instances.
  • B. Configure Autoscaling instance pool with LoadBalancer to add up to 3 more BM.Standard2.52 Instances when triggered. Shut off VM.Standard2.8 instances.
  • C. Route traffic to BM.Standard2.52 and VM Standard2.8 instances directly using DNS and Health Checks. Shut off the load Balances.
  • D. Configure your Load Balance, with weighted round robin policy to distribute traffic to the compute instances, with more weight assigned to bare metal instances.

Antwort: D

Customer have 4 BM.Standard2.52 and After several months he need additional compute capacity customer find The VM Standard2.8 Instances running at 100% of CPU utilization but the BM.Standard2 .52 instances have significant CPU capacity that unused.
so the customer need to check the Load balance policy to make sure the 4 BM and VM is utilize correctly

54. Frage
You are helping a customer troubleshoot a problem. The customer has several Oracle Linux servers in a private subnet within a Virtual Cloud Network (VCN). The servers are configured to periodically communicate to the Internet to get security patches for applications Installed on them.
The servers are unable to reach the Internet. An Internet Gateway has been deployed In the public subnet in the VCN and the appropriate routes are configured in the Route Table associated with the public subnet.
Based on cost considerations, which option will fix this Issue?

  • A. Implement a NAT instance In the public subnet of the VCN and configure the NAT instance as the route target for the private subnet.
  • B. Create a Public Load Balancer In front of the servers and add the servers to the Backend Set of the Public Load Balancer.
  • C. Create a NAT gateway in the VCN and configure the NAT gateway as the route target for the private subnet.
  • D. Create another Internet Gateway and configure it as route target for the private subnet.

Antwort: C

55. Frage
A cloud consultant is working on implementation project on OCI. As part of the compliance requirements, the objects placed in object storage should be automatically archived first and then deleted. He is testing a Lifecycle Policy on Object Storage and created a policy as below:
[ { “name”: “Archive_doc”, “action”: “ARCHIVE”, “objectNameFilter”: { “inclusionPrefixes”: “doc”] },
“timeAmount”: 5, “timeunit”: “DAYS”, “isEnabled”: true },
{ “name”: “Delete_doc”, “action”: “DELETE”, “objectNameFilter”: “inclusionPrefixes”: [ “doc”]
1.”timeAmount”: 5, “timeunit”: “DAYS”, “isEnabled”: true }
What will happen after this policy is applied?

  • A. All the objects having file extension “.doc” will be archived for 5 days and will be deleted 10 days after object creation
  • B. All objects with names starting with “doc” will be deleted after 5 days of object creation
  • C. All the objects having file extension “.doc” will be archived 5 days after object creation
  • D. All the objects with names starting with “doc” will be archived 5 days after object creation and will be deleted 5 days after archival

Antwort: B

Object Lifecycle Management works by defining rules that instruct Object Storage to archive or delete objects on your behalf within a given bucket. A bucket’s lifecycle rules are collectively known as an object lifecycle policy.
You can use a rule to either archive or delete objects and specify the number of days until the specified action is taken.
A rule that deletes an object always takes priority over a rule that would archive that same object.
