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?
A) Stackdriver
B) CloudWatch
C) Monitor
D) Dashboard

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 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?
A) IDS
B) IPS
C) IPC
D) IDP

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?
A) Scalability
B) Elasticity
C) Reliability
D) Availability

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?
A) Horizontal scaling
B) Vertical scaling
C) Triangular scaling
D) Linear scaling

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?
A) False positive
B) True positive
C) False negative
D) True negative

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?
A) Scale up
