CompTIA CV0-003 Online Questions & Answers

• Question 281:

  A cloud administrator has built a new private cloud environment and needs to monitor all computer, storage, and network components of the environment.

  Which of the following protocols would be MOST useful for this task?

  A. SMTP
  B. SCP
  C. SNMP
  D. SFTP
  C. SNMP

  ---

  Explanation

  Simple Network Management Protocol (SNMP) is a protocol that enables monitoring and managing network devices and components in an IP network. SNMP can help monitor all computer, storage, and network components of a private cloud environment, as it can collect and report information about their status, performance, configuration, and events. SNMP can also help troubleshoot and optimize the private cloud environment, as it can detect and alert any issues or anomalies related to the network devices and components.

• Question 282:

  A cloud administrator is looking at the company's cloud services bill for the previous month. The administrator notices on the billing dashboard that certain resources are not being billed to any particular department. Which of the following actions will help correct this billing issue?

  A. Check the utilization of the resources.
  B. Modify the chargeback details of the consumer.
  C. Add the resources to the consumer monitoring group.
  D. Modify the tags for all the unmapped resources.
  D. Modify the tags for all the unmapped resources.

• Question 283:

  A financial industry services firm was the victim of an internal data breach, and the perpetrator was a member of the company's development team. During the investigation. one of the security administrators accidentally deleted the perpetrator's user data. Even though the data is recoverable, which of the following has been violated?

  A. Chain of custody
  B. Evidence acquisition
  C. Containment
  D. Root cause analysis
  A. Chain of custody

  ---

  Explanation

  The chain of custody is a process that documents and preserves the integrity and authenticity of evidence from the time it is collected until it is presented in court. The chain of custody includes information such as who collected, handled, stored, or transferred the evidence, when and where it was done, and how it was done. By accidentally deleting the perpetrator's user data, the security administrator has violated the chain of custody, as the evidence has been altered or destroyed and can no longer be used in court.

• Question 284:

  A company is concerned it will run out of VLANs on its private cloud platform in the next couple months, and the product currently offered to customers requires the company to allocate three dedicated, segmented tiers. Which of the following can the company implement to continue adding new customers and to maintain the required level of isolation from other tenants?

  A. GRE
  B. SR-IOV
  C. VXLAN
  D. IPSec
  C. VXLAN

  ---

  Explanation

  One possible solution for the company to continue adding new customers and to maintain the required level of isolation from other tenants is to implement VXLAN. VXLAN is a network virtualization technology that can extend VLAN by adding a 24-bit segment ID, which allows up to 16 million unique virtual segments. VXLAN can encapsulate layer 2 Ethernet frames within layer 3 IP packets, and tunnel them across the underlying network. VXLAN can provide logical isolation and security for different tenants, as well as scalability and flexibility for large cloud computing environments1.

• Question 285:

  A systems administrator is reviewing two CPU models for a cloud deployment. Both CPUs have the same number of cores/threads and run at the same clock speed.

  Which of the following will BEST identify the CPU with more computational power?

  A. Simultaneous multithreading
  B. Bus speed
  C. L3 cache
  D. Instructions per cycle
  D. Instructions per cycle

  ---

  Explanation

  Instructions per cycle (IPC) is a metric that measures how many instructions a CPU can execute in one clock cycle. IPC can help identify the CPU with more computational power when comparing two CPU models that have the same number of cores/threads and run at the same clock speed, as it indicates the efficiency and performance of the CPU architecture and design. A higher IPC means that the CPU can process more instructions in less time, resulting in faster and better performance.

• Question 286:

  An organization was preparing to harden an environment before granting access to external auditors. Vulnerability testing was completed, and only one low-priority, informational vulnerability remained outstanding:

  

  Two weeks later, the auditors review the system on a new machine without an existing browser cache. Credentials are not required when accessing the application login page. Which of the following tests were skipped, causing this issue?

  A. Functionality testing
  B. Usability testing
  C. Regression testing
  D. Penetration testing
  C. Regression testing

• Question 287:

  A systems administrator is troubleshooting network throughput issues following a deployment. The network is currently being overwhelmed by the amount of traffic between the database and the web servers in the environment.

  Which of the following should the administrator do to resolve this issue?

  A. Set up affinity rules to keep web and database servers on the same hypervisor
  B. Enable jumbo frames on the gateway
  C. Move the web and database servers onto the same VXLAN
  D. Move the servers onto thick-provisioned storage
  A. Set up affinity rules to keep web and database servers on the same hypervisor

• Question 288:

  Which of the following definitions of serverless computing BEST explains how it is different from using VMs?

  A. Serverless computing is a cloud-hosting service that utilizes infrastructure that is fully managed by the CSP.
  B. Serverless computing uses predictable billing and offers lower costs than VM compute services.
  C. Serverless computing is a scalable, highly available cloud service that uses SDN technologies.
  D. Serverless computing allows developers to focus on writing code and organizations to focus on business.
  D. Serverless computing allows developers to focus on writing code and organizations to focus on business.

  ---

  Explanation

  This is the best definition of serverless computing that explains how it is different from using VMs (Virtual Machines). Serverless computing is a cloud service model that provides customers with a platform to run applications or functions without having to manage or provision any underlying infrastructure or resources, such as servers, storage, network, OS, etc. Serverless computing is different from using VMs in the following ways: Serverless computing allows developers to focus on writing code and organizations to focus on business, rather than spending time and effort on managing or scaling VMs or other infrastructure components. Serverless computing is event-driven and pay-per-use, which means that applications or functions are executed only when triggered by a specific event or request, and customers are charged only for the resources consumed during the execution time. Serverless computing is more scalable and flexible than using VMs, as it can automatically adjust the capacity and performance of applications or functions according to demand or workload, without requiring any manual intervention or configuration.

• Question 289:

  A systems administrator wants to have near-real-time information on the volume of data being exchanged between an application server and its clients on the Internet.

  Which of the following should the systems administrator implement to achieve this objective?

  A. A stateful firewall
  B. DLP
  C. DNSSEC
  D. Network flows
  D. Network flows

  ---

  Explanation

  Network flows are records of network traffic that capture information such as source and destination IP addresses, ports, protocols, timestamps, and byte and packet counts. Network flows can provide near-real-time information on the volume of data being exchanged between a system and its clients on the Internet, as they can measure and monitor the amount and rate of network traffic for each connection or session. Network flows can also help analyze network performance, troubleshoot network issues, and detect network anomalies or security incidents. A systems administrator should implement network flows to achieve the objective of having near-real-time information on the volume of data being exchanged between an application server and its clients on the Internet.
