CompTIA N10-008 Online Questions & Answers

• Question 1051:

  A customer lost the connection to the telephone system. The administration console is configured with multiple network interfaces and is connected to multiple switches. The network administrator troubleshoots and verifies the following:

  1.

  The support team is able to connect remotely to the administration console.

  2.

  Rebooting the switch shows solid link and activity lights even on unused ports.

  3.

  Rebooting the telephone system does not bring the system back online.

  4.

  The console is able to connect directly to individual modules successfully.

  Which of the following is the most likely reason the customer lost the connection?

  A. A switch failed.
  B. The console software needs to be reinstalled.
  C. The cables to the modules need to be replaced.
  D. A module failed.
  A. A switch failed.

• Question 1052:

  Which of the following ports should a network administrator enable for encrypted log-in to a network switch?

  A. 22
  B. 23
  C. 80
  D. 123
  A. 22

  ---

  Explanation/Reference:

  Port 22 is used by Secure Shell (SSH), which is a protocol that provides a secure and encrypted method for remote access to hosts by using public-key cryptography and challenge-response authentication. SSH can be used to log in to a network switch and configure it without exposing the credentials or commands to eavesdropping or tampering. Port 23 is used by Telnet, which is an insecure and plaintext protocol for remote access. Port 80 is used by HTTP, which is a protocol for web communication. Port 123 is used by NTP, which is a protocol for time synchronization

• Question 1053:

  A network administrator is configuring a load balancer for two systems. Which of the following must the administrator configure to ensure connectivity during a failover?

  A. VIP
  B. NAT
  C. APIPA
  D. IPv6 tunneling
  E. Broadcast IP
  A. VIP

  ---

  Explanation/Reference:

  - Virtual IP (VIP): A virtual IP address should be configured on the load balancer, which is the IP address that clients use to access the load-balanced systems.

• Question 1054:

  A Chief Executive Officer (CEO) of a company purchases a new phone that will be used while traveling to different countries. The CEO needs to be able to place outgoing calls and receive incoming calls on the phone using a SIM card. Which of the following cellular technologies does the CEO's phone need?

  A. WDMA
  B. CDMA
  C. GSM
  D. SLA
  C. GSM

  ---

  Explanation/Reference:

  GSM (Global System for Mobile Communications): GSM is a widely used cellular technology that enables voice and data communication over cellular networks. It is the most prevalent standard for mobile communication globally and is used by many countries. GSM phones use SIM cards (Subscriber Identity Module) to identify and authenticate the user on the network. This technology allows users to switch between different GSM networks by changing the SIM card while keeping the same device.

• Question 1055:

  A network switch was installed to provide connectivity to cameras monitoring wildlife in a remote location. The organization is concerned that intruders could potentially leverage unattended equipment in the remote location to connect rogue devices and gain access to the organization's resources. Which of the following techniques would BEST address the concern?

  A. Configure port security using MAC filtering.
  B. Manually register the cameras on the switch address table.
  C. Activate PoE+ on the active switchports.
  D. Disable Neighbor Discovery Protocol on the switch.
  A. Configure port security using MAC filtering.

  ---

  Explanation/Reference:

  Configure port security using MAC filtering would be the BEST technique to address the concern. Port security can be used to restrict access to an interface by limiting the MAC addresses that are allowed to send packets through the port. By configuring port security with MAC filtering, only the authorized MAC addresses of the cameras will be allowed to send packets through the switch ports, preventing rogue devices from connecting to the organization's resources.

• Question 1056:

  Users are reporting intermittent Wi-Fi connectivity in specific parts of a building. Which of the following should the network administrator check FIRST when troubleshooting this issue? (Select TWO).

  A. Site survey
  B. EIRP
  C. AP placement
  D. Captive portal
  E. SSID assignment
  F. AP association time
  A. Site survey
  C. AP placement

  ---

  Explanation/Reference:

  The two things the network administrator should check FIRST when troubleshooting intermittent WiFi connectivity issues in specific parts of a building are:

  1.

  Site survey: This is important to check because it provides information about the wireless coverage area, signal strength, and potential sources of interference, which can help to identify areas of weak or unstable signal.

  2.

  AP placement: This is also important to check because access point placement can greatly impact the WiFi coverage and signal strength. Incorrect placement, such as access points placed too far apart, can lead to poor coverage or areas with no coverage at all.

• Question 1057:

  To comply with an industry regulation, all communication destined to a secure server should be logged and archived on a storage device. Which of the Mowing can be configured to fulfill this requirement?

  A. QoS traffic classification
  B. Port mirroring
  C. Flow control
  D. Link Aggregation Control Protocol
  B. Port mirroring

  ---

  Explanation/Reference:

  To comply with an industry regulation that requires all communication destined to a secure server to be logged and archived, port mirroring can be configured to fulfill this requirement.

  Port mirroring is a feature that allows a network administrator to copy or "mirror" the traffic that passes through a specific port or set of ports on a network switch to a separate port where it can be monitored or analyzed. This can be useful for a variety of purposes, including security and troubleshooting.

  In this case, the network administrator could configure port mirroring on the port or ports that are used to communicate with the secure server. This would allow the administrator to copy all the traffic destined for the secure server to a separate port, where it could be logged and archived on a storage device. Other features such as QoS traffic classification, flow control, and Link Aggregation Control Protocol (LACP) may not be directly related to this requirement.

• Question 1058:

  The power company notifies a network administrator that it will be turning off the power to the building over the weekend. Which of the following is the BEST solution to prevent the servers from going down?

  A. Redundant power supplies
  B. Uninterruptible power supply
  C. Generator
  D. Power distribution unit
  C. Generator

  ---

  Explanation/Reference:

  UPS is an almost instant battery backup that prevents your devices and power from being interrupted, while generators have a longer start up time. Generators provide a much longer lasting backup power supply and can sustain your business for much longer than a UPS.

• Question 1059:

  Which of the following would need to be configured to ensure a device with a specific MAC address is always assigned the same IP address from DHCP?

  A. Scope options
  B. Reservation
  C. Dynamic assignment
  D. Exclusion
  E. Static assignment
  B. Reservation

• Question 1060:

  A company has decided to move its datacenter to an IaaS 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 risk?

  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.
