A company serves customers globally from its website hosted in North America. A cloud engineer recently deployed new instances of the website in the Europe region. Which of the following is the most likely reason?
A. To simplify workflow
B. To enhance security
C. To reduce latency
D. To decrease cost
Explanation:
The most likely reason for deploying new instances of a website in the Europe region, in addition to the ones hosted in North America, is to reduce latency for users located in Europe. By having the website's resources closer to the end-users, the data has a shorter distance to travel, resulting in faster load times and better performance.

An organization has been using an old version of an Apache Log4j software component in its critical software application. Which of the following should the organization use to calculate the severity of the risk from using this component?
A. CWE
B. CVSS
C. CWSS
D. CVE
Explanation:
The Common Vulnerability Scoring System (CVSS) is what the organization should use to calculate the severity of the risk from using an old version of Apache Log4j software component. CVSS provides an open framework for communicating the characteristics and impacts of IT vulnerabilities.

A cloud engineer was deploying the company's payment processing application, but it failed with the following error log:
ERFOR:root: Transaction failed http 429 response, please try again Which of the following are the most likely causes for this error? (Select two).
A. API throttling
B. API gateway outage
C. Web server outage
D. Oversubscription
E. Unauthorized access
F. Insufficient quota
Explanation:
The error "http 429 response, please try again" typically indicates API throttling, where the number of requests exceeds the rate limit set by the API provider, and insufficient quota, where the allowed number of API calls within a given timeframe has been exceeded.References: API throttling and quota management are key concepts in the management of cloud resources, as highlighted in the CompTIA Cloud+ curriculum.
Which of the following would allow a cloud engineer to flatten a deeply nested JSON log to improve readability for analysts?
A. Grafana
B. Kibana
C. Elastic search
D. Log stash
Explanation:
Log stash can be used to flatten a deeply nested JSON log, which would improve readability for analysts. Log stash is a data processing pipeline that ingests data from various sources, transforms it, and then sends it to a "stash" like Elastic search.

A systems administrator needs to configure backups for the company's on-premises VM cluster. The storage used for backups will be constrained on free space until the company can implement cloud backups. Which of the following backup types will save the most space, assuming the frequency of backups is kept the same?
A. Snapshot
B. Ful
C. Differential
D. Incremental
Explanation:
An incremental backup strategy saves space because it only backs up data that has changed since the last backup. Compared to full and differential backups, incremental backups aresmaller and save more space, which is essential when storage is constrained.
