Question 1

Which of the following is the most cost-effective way to store data that is infrequently accessed?

ACold site

BHot site

COff-site

DWarm site

Answer : C

The most cost-effective way to store data that is infrequently accessed is typically an off-site storage service, often referred to as cold or archival storage. This type of storage is designed for data that is rarely accessed, providing lower storage costs. Reference: Data storage solutions and their cost implications, including off-site (cold or archival) storage for infrequently accessed data, are part of the cloud storage options discussed in CompTIA Cloud+.

Question 2

An engineer made a change to an application and needs to select a deployment strategy that meets the following requirements:

* Is simple and fast

* Can be performed on two Identical platforms

Which of the following strategies should the engineer use?

ABlue-green

BCanary

CRolling

Din-place

Answer : A

The blue-green deployment strategy is ideal for scenarios where simplicity and speed are crucial. It involves two identical production environments: one (blue) hosts the current application version, while the other (green) is used to deploy the new version. Once testing is completed on the green environment and it's ready to go live, traffic is switched from blue to green, ensuring a quick and efficient rollout with minimal downtime. This method allows for immediate rollback if issues arise, by simply redirecting the traffic back to the blue environment. Reference: CompTIA Cloud+ material emphasizes the importance of understanding various cloud deployment strategies, including blue-green, and their application in real-world scenarios to ensure efficient and reliable software deployment in cloud environments.

Question 3

A company wants to use a solution that will allow for quick recovery from ransomware attacks, as well as intentional and unintentional attacks on data integrity and availability. Which of the following should the company implement that will minimize administrative overhead?

AObject versioning

BData replication

COff-site backups

DVolume snapshots

Answer : D

Implementing volume snapshots is an effective solution for quick recovery from ransomware attacks and protecting data integrity and availability. Snapshots capture the state of a storage volume at a point in time and can be used to restore data quickly with minimal administrative overhead. Reference: Data protection strategies like volume snapshots are discussed under cloud data management and protection in the CompTIA Cloud+ objectives.

Question 4

Which of the following is the best type of database for storing different types of unstructured data that may change frequently?

AVector

BRelational

CNon-relational

DGraph

Answer : C

Non-relational (NoSQL) databases are best for storing different types of unstructured data that may change frequently. They are designed to handle a wide variety of data types and are not constrained by the fixed schema of relational databases, making them more flexible and scalable for unstructured data. Reference: The distinction between relational and non-relational databases and their use cases is part of the foundational knowledge for cloud databases discussed in the CompTIA Cloud+ certification.

Question 5

Given the following command:

Sdocker pull images.comptia.org/user1/myimage:latest

Which of the following correctly identifies images.comptia.org?

AImage registry

BImage creator

CImage version

DImage name

Answer : A

In the Docker pull command given, images.comptia.org represents the image registry. A Docker image registry is a collection of repositories that host Docker images. It is where images are stored and organized, and from where they can be pulled for deployment. Reference: Docker and container management concepts, including image registries, are part of the cloud services understanding in the CompTIA Cloud+ curriculum.

Question 6

Users report being unable to access an application that uses TLS 1.1. The users are able to access other applications on the internet. Which of the following is the most likely

reason for this issue?

AThe security team modified user permissions.

BChanges were made on the web server to address vulnerabilities.

CPrivileged access was implemented.

DThe firewall was modified.

Answer : B

If users are unable to access an application that uses TLS 1.1 but can access other internet applications, it is likely that changes were made on the web server to address vulnerabilities, such as disabling outdated and less secure protocols like TLS 1.1. Reference: CompTIA Cloud+ Study Guide (Exam CV0-004) - Chapter on Cloud Security

Question 7

A systems administrator needs to configure a script that will monitor whether an application is healthy and stop the VM if an unsuccessful code is returned. Which of the following

scripts should the systems administrator use to achieve this goal?

ARESPONSE_CODE }
string APP_URL
bool RESPONSE_CODE
string VM
health checker (APP_URL, VM) {
if [ http_probe (APP_URL) == 200] {
echo RESPONSE_CODE }
else{
stop (VM)
echo

Belse{
echo
string APP_URL
float RESPONSE_CODE
string VM
health_checker (APP_URL, VM) {
if [ http_probe (APP_URL) == 200] {
stop (RESPONSE_CODE)
echo VM }
stop (VM)
RESPONSE CODE }

Celse{
echo
string APP_URL
int RESPONSE CODE
string VM
health checker (APP_URL, VM) {
if [ http_probe (APP_URL) == 200] {
echo RESPONSE_CODE }
stop (VM)
RESPONSE_CODE }

Delse{
echo
string APP_URL
int RESPONSE_CODE
string VM
health_checker (APP_URL, VM) {
if [ http_probe (VM) == 200] {
stop (VM)
echo RESPONSE_CODE }
RESPONSE CODE }

Answer : A

Script A is designed to monitor the health of an application by checking its response code. If the application returns a 200 (OK) status, it indicates that the application is healthy. Otherwise, the script will stop the VM to address the issue, which is a common approach to handle unhealthy application states in automated environments. This script effectively achieves the goal of monitoring application health and taking corrective action when an unsuccessful code is returned.
