A developer is deploying a new version of a containerized application. The DevOps team wants:

* No disruption

* No performance degradation

* Cost-effective deployment

* Minimal deployment time

Which of the following is the best deployment strategy given the requirements?

Canary
Canary
In-place
In-place
Blue-green
Blue-green
Rolling
Rolling
Suggested answer: C
Explanation:

The blue-green deployment strategy is the best given the requirements for no disruption, no performance degradation, cost-effective deployment, and minimal deployment time. It involves maintaining two identical production environments (blue and green), where one hosts the current application version and the other is used to deploy the new version. Once testing on the green environment is complete, traffic is switched from blue to green, ensuring a seamless transition with no downtime.

Reference: Understanding various cloud deployment strategies, such as blue-green deployments, is essential for managing cloud environments effectively, as highlighted in the CompTIA Cloud+ objectives, to ensure smooth and efficient application updates.

An DevOps engineer is receiving reports that users can no longer access the company's web application after hardening of a web server. The users are receiving the following error:

ERR_SSLJ/ERSION_OR_CIPHER_MISMATCH.

Which of the following actions should the engineer take to resolve the issue?

Restart the web server.
Restart the web server.
Configure TLS 1.2 or newer.
Configure TLS 1.2 or newer.
Update the web server.
Update the web server.
Review logs on the WAF
Review logs on the WAF
Suggested answer: B
Explanation:

To resolve the ERR_SSL_VERSION_OR_CIPHER_MISMATCH error after hardening a web server, the engineer should configure the server to use TLS 1.2 or newer. This error often occurs when the server or client supports an outdated version of SSL/TLS or incompatible cipher suites. Updating to a modern, secure version of TLS ensures compatibility and enhances security.

Reference: The CompTIA Cloud+ certification includes governance, risk, compliance, and security for the cloud, emphasizing the importance of implementing up-to-date security protocols like TLS to protect data in transit and ensure secure communications in cloud environments.

A healthcare organization must follow strict compliance requirements to ensure that Pll is not leaked. The cloud administrator needs to ensure the cloud email system can support this requirement Which of the following should the organization enable?

IPS
IPS
OLP
OLP
ACL
ACL
WAF
WAF
Suggested answer: B
Explanation:

To ensure that Personally Identifiable Information (PII) is not leaked and to comply with strict healthcare regulations, the organization should enable Data Loss Prevention (DLP). DLP systems are designed to detect and prevent unauthorized access or sharing of sensitive data, making them ideal for securing PII in cloud email systems and ensuring compliance with healthcare industry standards.

Reference: CompTIA Cloud+ content covers governance, risk, compliance, and security aspects of cloud computing, highlighting the role of DLP in safeguarding sensitive information and maintaining compliance in regulated industries like healthcare.

A cloud engineer wants to implement a monitoring solution to detect cryptojacking and other cryptomining malware on cloud instances. Which of the following metrics would most likely be used to identify the activity?

Disk I/O
Disk I/O
Network packets
Network packets
Average memory utilization
Average memory utilization
Percent of CPU utilization
Percent of CPU utilization
Suggested answer: D
Explanation:

To detect cryptojacking and other cryptomining malware on cloud instances, monitoring the percent of CPU utilization is most effective. Cryptomining malware typically consumes a significant amount of CPU resources for mining operations, leading to unusually high CPU usage. Monitoring and analyzing CPU utilization metrics can help identify instances of cryptojacking by highlighting abnormal levels of resource consumption.

Reference: Understanding management and technical operations in cloud environments, as outlined in the CompTIA Cloud+ objectives, includes the use of monitoring solutions to detect and respond to security threats like cryptomining malware, ensuring the integrity and performance of cloud resources.

Question 45

A developer is testing code that will be used to deploy a web farm in a public cloud. The main code block is a function to create a load balancer and a loop to create 1.000 web servers, as shown below:

CompTIA CV0-004 image Question 45 94995 10022024175116000000

The developer runs the code against the company's cloud account and observes that the load balancer is successfully created, but only 100 web servers have been created. Which of the following should the developer do to fix this issue?

Request an increase of Instance quota.
Request an increase of Instance quota.
Run the code multiple times until all servers are created.
Run the code multiple times until all servers are created.
Check the my_web_server () function to ensure it is using the right credentials.
Check the my_web_server () function to ensure it is using the right credentials.
Place the my_load_balancer () function after the loop.
Place the my_load_balancer () function after the loop.
Suggested answer: A
Explanation:

The developer should request an increase of the instance quota from the cloud provider. Cloud services often have a limit on the number of instances that can be created, which is known as an instance quota. If the load balancer is successfully created but the number of web servers is limited to 100, it suggests that the quota has been reached. Increasing the quota will allow the creation of additional web server instances up to the desired number.

Reference: The scenario reflects an understanding of cloud resource management and limitations, which is a part of the CompTIA Cloud+ curriculum, specifically under the domain of Management and Technical Operations.

Question 46

A cloud networking engineer is troubleshooting the corporate office's network configuration. Employees in the IT and operations departments are unable to resolve IP addresses on all devices, and the IT department cannot establish a connection to other departments' subnets. The engineer identifies the following configuration currently in place to support the office network:

CompTIA CV0-004 image Question 46 94996 10022024175116000000

Each employee needs to connect to the network with a maximum of three hosts. Each subnet must be segregated, but the IT department must have the ability to communicate with all subnets. Which of the following meet the IP addressing and routing requirements? (Select two).

Modifying the subnet mask to 255 255 254.0 for IT and operations departments
Modifying the subnet mask to 255 255 254.0 for IT and operations departments
Configuring static routing to allow access from each subnet to 10.1.40.1
Configuring static routing to allow access from each subnet to 10.1.40.1
Modifying the BYOD policy to reduce the volume of devices that are allowed to connect to the corporate network
Modifying the BYOD policy to reduce the volume of devices that are allowed to connect to the corporate network
Configuring static routing to allow access from 10.1.30.1 to each subnet
Configuring static routing to allow access from 10.1.30.1 to each subnet
Combining the subnets and increasing the allocation of IP addresses available to support three hosts for each employee
Combining the subnets and increasing the allocation of IP addresses available to support three hosts for each employee
Modifying the subnet mask to 255.255.255.128 for the IT and operations departments
Modifying the subnet mask to 255.255.255.128 for the IT and operations departments
Suggested answer: D, F
Explanation:

To meet the requirements of allowing the IT department to communicate with all subnets while keeping each department segregated and ensuring a maximum of three hosts per employee, two actions are required. First, configuring static routing from the IT subnet (10.1.30.1) to each of the other subnets would establish the necessary connectivity. Second, modifying the subnet mask to 255.255.255.128 for the IT and operations departments would provide the needed number of host addresses while maintaining subnet segregation.

Reference: This solution is based on networking and subnetting principles, which are part of the foundational knowledge for cloud networking within the CompTIA Cloud+ framework.
