CompTIA N10-008 Online Questions & Answers

• Question 11:

  A network administrator is talking to different vendors about acquiring technology to support a new project for a large company. Which of the following documents will MOST likely need to be signed before information about the project is shared?

  A. BYOD policy
  B. NDA
  C. SLA
  D. MOU
  B. NDA

  ---

  Explanation/Reference:

  NDA stands for Non-Disclosure Agreement, which is a legal contract between two or more parties that outlines confidential material, knowledge, or information that the parties wish to share with one another for certain purposes, but wish to restrict access to by others. A network administrator may need to sign an NDA before sharing information about a new project with different vendors, as the project may involve sensitive or proprietary data that the company wants to protect from competitors or unauthorized use.

• Question 12:

  A customer reports there is no access to resources following the replacement of switches. A technician goes to the site to examine the configuration and discovers redundant links between two switches. Which of the following is the reason the network is not functional?

  A. The ARP cache has become corrupt.
  B. CSMA/CD protocols have failed.
  C. STP is not configured.
  D. The switches are incompatible models.
  C. STP is not configured.

  ---

  Explanation/Reference:

  The redundant links between two switches without STP (Spanning Tree Protocol) can cause a network loop. When a network loop occurs, the switches will forward traffic endlessly in a loop, which can cause a network outage or poor network performance. Therefore, if there are redundant links between two switches and STP is not configured, it can cause the network to be non-functional.

  ARP (Address Resolution Protocol) cache corruption (option A) can cause connectivity issues, but it is not related to redundant links or STP.

  CSMA/CD (Carrier Sense Multiple Access/Collision Detection) protocols (option B) are used in Ethernet networks to detect and recover from collisions, and are not directly related to redundant links or STP.

  Incompatible switch models (option D) can cause issues with connectivity, but it is unlikely to be the cause of non-functional network after the replacement of switches, especially if the replacement switches are of the same make and model as the original switches.n switches

• Question 13:

  Which of the following technologies allows traffic to be sent through two different ISPs to increase performance?

  A. Fault tolerance
  B. Quality of service
  C. Load balancing
  D. Port aggregation
  A. Fault tolerance

  ---

  Explanation/Reference:

  Load balancing is a technology that allows traffic to be sent through two different ISPs to increase performance. Load balancing is a process of distributing network traffic across multiple servers or links to optimize resource utilization, throughput, latency, and reliability. Load balancing can be implemented at different layers of the OSI model, such as layer 4 (transport) or layer 7 (application). Load balancing can also be used for outbound traffic by using multiple ISPs and routing protocols such as BGP (Border Gateway Protocol) to select the best path for each packet.

• Question 14:

  A network technician is installing an analog desk phone for a new receptionist After running a new phone line, the technician now needs to cnmp on a new connector. Which of the following connectors would MOST likely be used in this case?

  A. DB9
  B. RJ11
  C. RJ45
  D. DB25
  B. RJ11

  ---

  Explanation/Reference:

  RJ11 as discussed before was widely used in analog telephony to connect the phone instrument and the cable.

• Question 15:

  An organization wants to implement a method of centrally managing logins to network services. Which of the following protocols should the organization use to allow for authentication, authorization and auditing?

  A. MS-CHAP
  B. RADIUS
  C. LDAPS
  D. RSTP
  B. RADIUS

  ---

  Explanation/Reference:

  RADIUS (Remote Authentication Dial-In User Service) is a protocol that should be used by the organization to allow for authentication, authorization, and auditing of network services. RADIUS is an AAA (Authentication, Authorization, and Accounting) protocol that manages network access by verifying user credentials, granting access permissions, and logging user activities. RADIUS uses a client-server model where a RADIUS client (such as a router, switch, or VPN server) sends user information to a RADIUS server (such as an authentication server) for verification and authorization. The RADIUS server can also send accounting information to another server for billing or reporting purposes.

• Question 16:

  A network administrator needs to keep track of the locations of installed network equipment. Which of the following would be the BEST method to accomplish this task?

  A. Tamper detection
  B. Asset tags
  C. Video surveillance
  D. Motion detection
  B. Asset tags

• Question 17:

  A technician is setting up DNS records on local servers for the company's cloud DNS to enable access by hostname. Which of the following records should be used?

  A. A
  B. MX
  C. CNAME
  D. NS
  C. CNAME

  ---

  Explanation/Reference:

  CNAME (Canonical Name) record: A CNAME record is used to create an alias or pointer to another domain name. It allows you to associate multiple hostnames with a single IP address or another domain name. In this scenario, using a CNAME record, you can map a hostname on your local servers to the corresponding hostname in the company's cloud DNS. This is useful when you want to provide a user-friendly name for accessing resources in the cloud.

• Question 18:

  Which of the following options represents the participating computers in a network?

  A. Nodes
  B. CPUs
  C. Servers
  D. Clients
  A. Nodes

  ---

  Explanation/Reference:

  In a broader sense, "node" is a general term that refers to any device connected to a network. This can include devices that play various roles, such as servers, routers, switches, hubs, and even individual computers or devices like printers. A

  node is essentially any point of connection within a network, whether it's a device responsible for managing traffic (like routers and switches) or devices that consume resources (like computers and smartphones).

  Clients:

  Clients are a specific type of node in a network architecture. They are devices that request and consume services, data, or resources from other devices or servers on the network. Clients are typically end-user devices, such as computers,

  laptops, smartphones, tablets, or any device that accesses and interacts with resources provided by servers or other devices.

  Clients initiate requests to servers for services like web browsing, email, file sharing, and more.

  A. 53
  B. 389
  C. 445
  D. 1433

  Explanation/Reference:

  Server Message Block is used for file transfer over TCP port 445.
