CompTIA N10-008 Online Questions & Answers

• Question 791:

  A new cabling certification is being requested every time a network technician rebuilds one end of a Cat 6 (vendor-certified) cable to create a crossover connection that is used to connect switches. Which of the following would address this issue by allowing the use of the original cable?

  A. CSMA/CD
  B. LACP
  C. PoE+
  D. MDIX
  D. MDIX

  ---

  Explanation/Reference:

  MDIX (Media Dependent Interface Crossover) would address this issue by allowing the use of the original cable for connecting switches. MDIX automatically detects and compensates for cable crossover, eliminating the need for a crossover cable.

• Question 792:

  A network technician needs to ensure that all files on a company's network can be moved in a safe and protected manner without interception from someone who is not the intended recipient. Which of the following would allow the network technician to meet these requirements?

  A. FTP
  B. TFTP
  C. SMTP
  D. SFTP
  D. SFTP

  ---

  Explanation/Reference:

  SFTP (Secure File Transfer Protocol) is a secure and encrypted method for transferring files over a network. It ensures that data is protected from interception and only accessible by the intended recipient. FTP and TFTP do not provide encryption, while SMTP is a protocol used for email transmission, not file transfer.

• Question 793:

  A network technician wants to find the shortest path from one node to every other node in the network. Which of the following algorithms will provide the FASTEST convergence time?

  A. A static algorithm
  B. A link-state algorithm
  C. A distance-vector algorithm
  D. A path-vector algorithm
  B. A link-state algorithm

• Question 794:

  A network engineer is provisioning a new Linux server in a public cloud. Which of the following types of cloud service should be utilized?

  A. PaaS
  B. SaaS
  C. DaaS
  D. laaS
  D. laaS

• Question 795:

  Which of the following can be used to validate domain ownership by verifying the presence of pre-agreed content contained in a DNS record?

  A. SOA
  B. SRV
  C. AAA
  D. TXT
  D. TXT

  ---

  Explanation/Reference:

  "One final usage of the TXT resource record is how some cloud service providers, such as Azure, validate ownership of custom domains. You are provided with data to include in your TXT record, and once that is created, the domain is verified and able to be used. The thought is that if you control the DNS, then you own the domain name."

• Question 796:

  A network technician is responding to an issue with a local company. To which of the following documents should the network technician refer to determine the scope of the issue?

  A. MTTR
  B. MOU
  C. NDA
  D. SLA
  D. SLA

  ---

  Explanation/Reference:

  A Service Level Agreement (SLA) is a contract between a service provider and a customer that outlines the level of service that the provider will deliver. It typically includes details on the scope of the service being provided, the availability and

  performance of the service, and any support or maintenance that is included.

  The Mean Time To Repair (MTTR) is a measure of the time it takes to repair a failed component or system. It is not directly related to determining the scope of an issue.

  A Memorandum of Understanding (MOU) is a formal agreement between two or more parties that outlines the terms and conditions of their relationship. It is not typically used to determine the scope of an issue.

  A Non-Disclosure Agreement (NDA) is a legal document that prohibits the disclosure of confidential information. It is not related to determining the scope of an issue.

• Question 797:

  Which of the following are environmental factors that should be considered when installing equipment in a building? (Choose two.)

  A. Fire suppression system
  B. UPS location
  C. Humidity control
  D. Power load
  E. Floor construction type
  F. Proximity to nearest MDF
  A. Fire suppression system
  C. Humidity control

  ---

  Explanation/Reference:

  Fire suppression system: Ensures that the facility has adequate measures in place to suppress or extinguish fires in case of emergencies, protecting both equipment and personnel. Humidity control: Maintaining proper humidity levels is crucial for the optimal performance and longevity of electronic equipment. Excessive humidity can lead to condensation and potential damage.

• Question 798:

  A customer is having issues accessing local resources on the network. A technician questions the user and discovers that a small switch had been taken out of storage and installed so that additional devices could be connected in the room.

Which of the following is the most likely cause of the issue?

  A. Duplexing mismatch
  B. Reversed TX/RX pinouts
  C. Cable crosstalk
  D. Failed transceiver
  A. Duplexing mismatch
