Question 1

A company serves customers globally from its website hosted in North Americ

a. A cloud engineer recently deployed new instances of the website in the Europe region. Which of the

following is the most likely reason?

ATo simplify workflow

BTo enhance security

CTo reduce latency

DTo decrease cost

Answer : C

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.

Question 2

The company's IDS has reported an anomaly. The cloud engineer remotely accesses the cloud instance, runs a command, and receives the following information:

Which of the following is the most likely root cause of this anomaly?

APrivilege escalation

BLeaked credentials

CCryptojacking

DDefaced website

Answer : A

The output from the 'ps' command indicates there is a process running under the UID (User ID) of 0, which is the root user, and the command that was run is '/var/www/command.py'. Given that the normal Apache processes are running under their own UID (65535), this suggests that a command was executed with root privileges that typically should not have such high-level access. This is a strong indicator of privilege escalation, where an unauthorized user or process gains elevated access to resources that are normally protected from an application or user.

Question 3

A developer is building an application that has multiple microservices that need to communicate with each other. The developer currently manually updates the IP address of each service. Which of the following best resolves the communication issue and automates the process?

AService discovery

BFan-out

CManaged container services

DDNS

Answer : A

Service discovery is a key component in microservices architectures, allowing services to dynamically discover and communicate with each other. By implementing service discovery, the developer can automate the process of updating service addresses, resolving the communication issue without manual updates to IP addresses, thus ensuring seamless interaction between the microservices.

Question 4

A company receives files daily from a bank. The company requires that the files must be copied from the cloud storage resource to another cloud storage resource for further

processing. Which of the following methods requires the least amount of effort to achieve the task?

ARemote procedure call

BSOAP

CEvent-driven architecture

DREST

Answer : C

An event-driven architecture is the most efficient method for automating the task of copying files from one cloud storage resource to another upon their arrival. This architecture allows systems to automatically trigger actions based on specific events, such as the arrival of new files, minimizing manual effort and ensuring timely processing.

Question 5

A company is required to save historical data for seven years. A cloud administrator implements a script that automatically deletes data older than seven years. Which of the following concepts best describes why the historical data is being deleted?

AEnd of life

BData loss prevention

CCost implications

DTiered storage for archiving

Answer : A

Deleting historical data older than seven years as described is an example of data end of life (EOL) policies in action. These policies dictate when data is no longer needed or relevant and should be securely disposed of, often for compliance, legal, or cost-saving reasons.

Question 6

Which of the following describes the main difference between public and private container repositories?

APrivate container repository access requires authorization, while public repository access does not require authorization.

BPrivate container repositories are hidden by default and containers must be directly referenced, while public container repositories allow browsing of container images.

CPrivate container repositories must use proprietary licenses, while public container repositories must have open-source licenses.

DPrivate container repositories are used to obfuscate the content of the Dockerfile, while public container repositories allow for Dockerfile inspection.

Answer : A

The main difference between public and private container repositories lies in access control. Public repositories allow users to download and use container images without requiring any authorization, making them accessible to anyone. On the other hand, private repositories require users to have proper authorization, usually through credentials, to access the container images, thus providing a level of privacy and security control.

Question 7

A cloud engineer is running a latency-sensitive workload that must be resilient and highly available across multiple regions. Which of the following concepts best addresses these

requirements?

ACloning

BClustering

CHardware passthrough

DStand-alone container

Answer : B

Clustering refers to the use of multiple servers/computers to form what appears to be a single system. This concept is key for achieving high availability and resilience, especially for latency-sensitive workloads. By distributing the workload across a cluster that spans multiple regions, the system can continue to operate even if one or more nodes fail, thus maintaining performance and availability.
