Question 146

A security engineer recently discovered a vulnerability in the operating system of the company VMs. The operations team reviews the issue and decides all VMs need to be updated from version 3.4.0 to 3.4.1. Which of the following best describes the type of update that will be applied?

Correct Answer: C
The update from version 3.4.0 to 3.4.1 is considered a minor update, typically involving small bug fixes or security patches that do not include major feature changes or improvements. Reference: CompTIA Cloud+ Study Guide (Exam CV0-004) - Chapter on Systems Management

Question 147

The QA team is testing a newly implemented clinical trial management (CTM) SaaS application that uses a business intelligence application for reporting. The UAT users were instructed to use HTTP and HTTPS.
Refer to the application dataflow:
1A - The end user accesses the application through a web browser to enter and view clinical data.
2A - The CTM application server reads/writes data to/from the database server.
1B - The end user accesses the application through a web browser to run reports on clinical data.
2B - The CTM application server makes a SOAP call on a non-privileged port to the BI application server.
3B - The BI application server gets the data from the database server and presents it to the CTM application server.
When
UAT users try to access the application using https://ctm.app.com or http://ctm.app.com, they get a message stating: "Browser cannot display the webpage." The QA team has raised a ticket to troubleshoot the issue.
INSTRUCTIONS
You are a cloud engineer who is tasked with reviewing the firewall rules as well as virtual network settings.
You should ensure the firewall rules are allowing only the traffic based on the dataflow.
You have already verified the external DNS resolution and NAT are working.
Verify and appropriately configure the VLAN assignments and ACLs. Drag and drop the appropriate VLANs to each tier from the VLAN Tags table. Click on each Firewall to change ACLs as needed.
If at any time you would like to bring back the initial state of the simulation, please click the Reset All button.




Correct Answer:
See explanation below.
Explanation:
On firewall 3, change the DENY 0.0.0.0 entry to rule 3 not rule 1.

Question 148

Five thousand employees always access the company's public cloud-hosted web application on a daily basis during the same time frame. Some users have been reporting performance issues while attempting to connect to the web application Which of the following is the best configuration approach to resolve this issue?

Correct Answer: B
Scaling horizontally means adding more instances of the application or servers to handle increased traffic, rather than increasing the resources (CPU, memory) of a single server (which would be vertical scaling). Since the performance issues occur during a specific, predictable time frame every day, scaling horizontally based on a schedule would ensure that additional resources are available when needed, improving performance without waiting for a load threshold to be reached.

Question 149

A cloud engineer is exploring options to reduce the management overhead of the servers and network. Which of the following cloud service models should the engineer implement?

Correct Answer: C
Platform as a Service (PaaS) provides a platform allowing customers to develop, run, and manage applications without the complexity of building and maintaining the infrastructure typically associated with developing and launching an app. Adopting PaaS can significantly reduce the management overhead of servers and networks.

Question 150

A company wants to build its new platform using a public cloud. The workload requirements include the following:
* Implementation of custom CIS compliance
* Patch for vulnerabilities within 24 hours
* Warrant at least 1,800 IOPS per volume
Which of the following meets the requirements?

Correct Answer: B
Infrastructure as a Service (IaaS) provides the most flexibility among cloud service models, allowing for the implementation of custom security and compliance standards, such as CIS compliance. IaaS environments offer control over the infrastructure, enabling patch management within specific time frames. Additionally, IaaS providers typically offer configurable storage options, including the ability to specify IOPS (Input/Output Operations Per Second) per volume to meet performance requirements.
