Everything You Need to Pass: CompTIA CV0-003

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

A DevOps administrator is automating an existing software development workflow. The administrator wants to ensure that prior to any new code going into production, tests confirm the new code does not negatively impact existing automation activities. Which of the following testing techniques would be BEST to use?

A marketing team is using a SaaS -based service to send emails to large groups of potential customers. The internally managed CRM system is configured to generate a list of target customers automatically on a weekly basis, and then use that list to send emails to each customer as part of a marketing campaign. Last week, the first email campaign sent emails successfully to 3,000 potential customers. This week, the email campaign attempted to send out 50,000 emails, but only 10,000 were sent. Which of the following is the MOST likely reason for not sending all the emails?

A VDI administrator has received reports of poor application performance. Which of the following should the administrator troubleshoot FIRST?

Due to a policy change, a few of a customer’s application VMs have been migrated to synchronously replicated storage. The customer now reports that performance is lower. The systems administrator checks the resource usage and discovers CPU utilization is at 60% and available memory is at 30%. Which of the following is the MOST likely cause?

A company has decided to scale its e-commerce application from its corporate datacenter to a commercial cloud provider to meet an anticipated increase in demand during an upcoming holiday. The majority of the application load takes place on the application server under normal conditions. For this reason, the company decides to deploy additional application servers into a commercial cloud provider using the on-premises orchestration engine that installs and configures common software and network configurations. The remote computing environment is connected to the on-premises datacenter via a site-to-site IPSec tunnel. The external DNS provider has been configured to use weighted round -robin routing to load balance connections from the Internet. During testing, the company discovers that only 20% of connections completed successfully. INSTRUCTIONS Review the network architecture and supporting documents and fulfill these requirements: Part 1: Analyze the configuration of the following components: DNS, Firewall 1, Firewall 2, Router 1, Router 2, VPN and Orchestrator Server. Identify the problematic device(s). Part 2: Identify the correct options to provide adequate configuration for hybrid cloud architecture. If at any time you would like to bring back the initial state of the simulation, please click the Reset All button. Part 1: Cloud Hybrid Network Diagram Part 2: Only select a maximum of TWO options from the multiple choice question Explanation: Part 1: Router 2 ee explanation below. The problematic device is Router 2, which has an incorrect configuration for the IPSec tunnel. The IPSec tunnel is a secure connection between the on-premises datacenter and the cloud provider, which allows the traffic to flow between the two networks. The IPSec tunnel requires both endpoints to have matching parameters, such as the IP addresses, the pre-shared key (PSK), the encryption and authentication algorithms, and the security associations (SAs) . According to the network diagram and the configuration files, Router 2 has a different PSK and a different address space than Router 1. Router 2 has a PSK of “1234567890”, while Router 1 has a PSK of “0987654321”. Router 2 has an address space of 10.0.0.0/8, while Router 1 has an address space of 192.168.0.0/16. These mismatches prevent the IPSec tunnel from establishing and encrypting the traffic between the two networks. The other devices do not have any obvious errors in their configuration. The DNS provider has two CNAME records that point to the application servers in the cloud provider, with different weights to balance the load. The firewall rules allow the traffic from and to the application servers on port 80 and port 443, as well as the traffic from and to the VPN server on port 500 and port 4500. The orchestration server has a script that installs and configures the application servers in the cloud provider, using the DHCP server to assign IP addresses. Part 2: The correct options to provide adequate configuration for hybrid cloud architecture are: Update the PSK in Router 2. Change the address space on Router 2. These options will fix the IPSec tunnel configuration and allow the traffic to flow between the on- premises datacenter and the cloud provider. The PSK should match the one on Router 1, which is “0987654321”. The address space should also match the one on Router 1, which is 192.168.0.0/16. B. Update the PSK (Pre-shared key in Router2) E. Change the Address Space on Router2
