CompTIA N10-008 Online Questions & Answers

• Question 1131:

  A network administrator needs to monitor traffic on a specific port on a switch. Which of the following should the administrator configure to accomplish the task?

  A. Port security
  B. Port tagging
  C. Port mirroring
  D. Media access control
  C. Port mirroring

• Question 1132:

  A network technician is selecting a replacement for a damaged fiber cable that goes directly to an SFP transceiver on a network switch. Which of the following cable connectors should be used?

  A. RJ45
  B. LC
  C. MT
  D. F-type
  B. LC

  ---

  Explanation/Reference:

  All SFP and SFP+ optics require LC connectors so the question becomes when you need single mode fiber or multi mode fiber but the connector type is clear. SC square connectors are too big to fit in a SFP or SFP+

• Question 1133:

  Which of the following services can provide data storage, hardware options, and scalability to a third-party company that cannot afford new devices?

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

  ---

  Explanation/Reference:

  IaaS stands for Infrastructure as a Service, which is a cloud computing model that provides virtualized computing resources such as servers, storage, and networking over the Internet. IaaS can provide data storage, hardware options, and

  scalability to a third-party company that cannot afford new devices by allowing them to rent or lease the infrastructure they need from a cloud provider. The company can pay only for what they use and scale up or down as needed.

• Question 1134:

  Which of the following synchronizes time on all devices within a network?

  A. DHCP
  B. DNS
  C. NTP
  D. SNMP
  C. NTP

  ---

  Explanation/Reference:

  Network Time Protocol (NTP): NTP is a widely adopted protocol for synchronizing clocks across network devices. It ensures that all devices have accurate and consistent time. NTP uses a hierarchical system of time sources to maintain synchronization.

• Question 1135:

  A network administrator needs to query the NSs for a remote application. Which of the following commands would BEST help the administrator accomplish this task?

  A. dig
  B. arp
  C. show interface
  D. hostname
  A. dig

  ---

  Explanation/Reference:

  dig (Domain information groper) is the command line tool to query DNS nameserver in linux

• Question 1136:

  A client who shares office space and an IT closet with another company recently reported connectivity issues throughout the network. Multiple third-party vendors regularly perform on-site maintenance in the shared IT closet. Which of the following security techniques would BEST secure the physical networking equipment?

  A. Disabling unneeded switchports
  B. Implementing role-based access
  C. Changing the default passwords
  D. Configuring an access control list
  B. Implementing role-based access

  ---

  Explanation/Reference:

  Role-based access is a security technique that assigns permissions and privileges to users or groups based on their roles or functions within an organization. Role- based access can help secure the physical networking equipment by limiting who can access, modify, or manage the devices in the shared IT closet. Only authorized personnel with a valid role and credentials should be able to access the networking equipment. Disabling unneeded switchports is a security technique that prevents unauthorized devices from connecting to the network by turning off unused ports on a switch. Changing the default passwords is a security technique that prevents unauthorized access to network devices by replacing the factory-set passwords with strong and unique ones. Configuring an access control list is a security technique that filters network traffic by allowing or denying packets based on criteria such as source and destination IP addresses, ports, or protocols.

• Question 1137:

  An organization has a guest network with a network IP range of 192.168.1.0/28 using a DHCP pool. One visitor reported difficulties connecting and configured a static IP address. Following this action, another visitor reported intermittent connection issues. Which of the following is the most likely reason?

  A. Address pool exhaustion
  B. Duplicate IP addresses
  C. Misconfigured default gateway
  D. Incorrect subnet mask
  B. Duplicate IP addresses

  ---

  Explanation/Reference:

  A duplicate IP address occurs when two devices on the same network have the same IP address assigned to them. This can cause intermittent connection issues, as the network devices may not be able to distinguish between the two conflicting devices. A duplicate IP address can be caused by a visitor manually configuring a static IP address that is already in use by another device on the guest network. The network IP range of 192.168.1.0/28 has only 14 usable host addresses, so the chances of a duplicate IP address are higher than a larger network.

• Question 1138:

  A company has decided to move its datacenter to an laaS provider. The company stakeholders are concerned about their ISP being a single point of failure. Which of the following will the network administrator MOST likely recommend to mitigate this nsk?

  A. Adopt a multicloud strategy to ensure access in case of an outage.
  B. Contract a secondary ISP to provide another connection.
  C. Lease additional office space for use in the event of a disaster.
  D. Get an additional Internet connection from the current ISP
  B. Contract a secondary ISP to provide another connection.

• Question 1139:

  A network technician is connecting medical monitoring devices on a personal area network for patients' phones. Which of the following technologies should be used?

  A. Bluetooth
  B. ROD
  C. NFC
  D. IR
  A. Bluetooth

• Question 1140:

  Which of the following routing protocols should be implemented to create a route between a local area network and an ISP?

  A. BGP
  B. EIGRP
  C. RIP
  D. OSPF
  A. BGP

  ---

  Explanation/Reference:

  BGP (Border Gateway Protocol): BGP is designed for routing between different autonomous systems (ASes) on the internet. It is used to exchange routing and reachability information between ISPs, enterprises, and other networks. BGP is well-suited for handling large-scale networks and providing policy-based routing control.
