A false positive occurs when an alert or warning is issued incorrectly, indicating a problem where there is none. Since Sandra found the system running fine despite the alert, it's a false positive scenario.

Question 4

Syed is implementing an event monitoring system that will be able to look at all events and determine if there is a pattern established by the different events that occur. Which of the following would be a feature of this monitoring system?

Accepted Answer

Event correlation is the process of analyzing and identifying relationships between events, which is exactly what Syed's system aims to do by determining patterns among different events.

Question 5

Jack gets an alert that one of his web servers is receiving more requests than it can handle given its current resources. He has decided to implement vertical scaling to resolve the issue. Which of the following could he do to meet his objective?

Accepted Answer

Vertical scaling involves increasing the capacity of existing hardware or software by adding resources to a single node in the system, such as adding more vCPUs and memory to the virtual machine, rather than adding more nodes to the system.

Question 6

Summer is analyzing one of the company's database servers and sees that it is currently using 90 percent of its allocated disk space. Which of the following could she do without creating another server to split the load with?

Accepted Answer

Scaling up involves increasing the resources of the existing server, such as adding more disk space, which would address the issue without creating another server.

Question 7

James is looking at his company's dashboard that is laid out with a number of metrics and goals that are measured for the company's cloud deployment. Which of the following is a common term used for a metric that the company may measure and report on?

Accepted Answer

KPI stands for Key Performance Indicator, which is a common term used for a metric that companies measure and report on to evaluate their success at reaching targets.

Question 8

Fatima is implementing a new monitoring system that is looking for detectable changes in a cloud resource's state. Which of the following describes these changes of state?

Accepted Answer

Events describe detectable changes in a cloud resource's state. These can include updates, system errors, or any significant condition changes that monitoring systems are designed to detect and possibly act upon.

Question 9

Jed has just spent some time analyzing some of the applications on the cloud service provider his company uses. He found that one of the applications was using a lot of resources between the servers that it was deployed on and implemented horizontal scaling to resolve the issue. Which of the following did Jed do?

Accepted Answer

Horizontal scaling, which Jed implemented, involves increasing the number of servers available to the application to distribute the load more effectively, rather than increasing the capacity of existing servers (vertical scaling) or moving the application to a different environment.

Question 10

Fictional Corp has chosen to use AWS as its cloud service provider. One of the key benefits that it liked about the platform was a service that allows technicians to monitor metrics across AWS services by collating data in one or more dashboards, tracking events, or generating alerts. Which of the following AWS services were they impressed by?

Accepted Answer

CloudWatch is the AWS service that enables monitoring and operational management by providing data and actionable insights to monitor applications, respond to system-wide performance changes, optimize resource utilization, and get a unified view of operational health. Stackdriver is associated with Google Cloud, not AWS, and the options "Monitor" and "Dashboard" are not specific AWS services related to the described functionality.

Question 11

Eddie has been analyzing one of the clusters hosted in their on-premises data center. He sees that several of the servers are consistently sitting idle. Which of the following techniques might she want to do?

Accepted Answer

The answer of Eddie has been analyzing one of the...

Question 12

Fictional Corp implements multiple methods of keeping attackers out of its network and systems. Some of these systems may simply report on the intrusions while others will attempt to stop them while in progress. Which of the following describes the concept that Fictional Corp has implemented?

Accepted Answer

An Intrusion Detection and Prevention (IDP) system combines the capabilities of an Intrusion Detection System (IDS) and an Intrusion Prevention System (IPS). An IDS monitors network traffic for suspicious activity and generates alerts, while an IPS actively blocks or drops malicious traffic. By combining these capabilities, an IDP system provides both detection and prevention capabilities.

Question 13

Fictional Corp has decided to use a cloud service provider rather than continue to build out the standard infrastructure they had been creating and using in their on-premises data center. The primary deciding factor is that the cloud services can add or remove resources from servers or add or remove virtual machines without any human intervention. Which of the following features is the reason why Fictional Corp chose to use a cloud service provider?

Accepted Answer

Elasticity is the feature that allows cloud services to automatically add or remove resources or virtual machines based on demand, without human intervention. This is why Fictional Corp chose a cloud service provider.

Question 14

Bob pulls up the company's dashboard and sees that one of the virtual machines is running low on storage space. He logs into the cloud provider's portal and increases the size of the virtual disk so that it will not run out unexpectedly and start causing errors. Which of the following processes has Bob just performed?

Accepted Answer

Bob has performed vertical scaling, which involves increasing the capacity of an existing resource, such as adding more storage to a virtual machine, without changing the number of resources or instances.

Question 15

Niles is analyzing a server and finds a problem with one of the applications. He didn't receive any notifications and thinks that perhaps it got lost in his spam folder or something else happened. After scouring the logs, he doesn't see any notifications or alerts in the system at all. Which of the following describes this situation?

Accepted Answer

A false negative occurs when an issue exists (like the problem with the application Niles found) but the system fails to detect and alert it, which matches the situation described.

Question 16

Trish has been analyzing the company's resources on the cloud service provider her company uses. She sees that a cluster is running at near capacity and decides to add another virtual machine to the cluster. Which of the following would describe this scenario?

Accepted Answer

Adding another virtual machine to a cluster to handle increased load or capacity needs is described as "scaling out." This involves increasing the number of resources or nodes in a system to handle the load, as opposed to "scaling up," which would involve increasing the resources of the existing machines.

Question 17

Fictional Corp has a datacenter located next to a major river. Until now, the area has never flooded before, according to records that exist, but it has now been hit with what is being called a 1000-year flood.
