CompTIA N10-008 Online Questions & Answers

• Question 1121:

  Which of the following would be the BEST choice to connect branch sites to a main office securely?

  A. VPN headend
  B. Proxy server
  C. Bridge
  D. Load balancer
  A. VPN headend

  ---

  Explanation/Reference:

  Host-to-Site, or Client-to-Site, VPN allows for remote servers, clients, and other hosts to establish tunnels through a VPN gateway (or VPN headend) via a private network. The tunnel between the headend and the client host encapsulates and encrypts data.

• Question 1122:

  A network technician recently installed 35 additional workstations. After installation, some users are unable to access network resources. Many of the original workstations that are experiencing the network access issue were offline when the new workstations were turned on. Which of the following is the MOST likely cause of this issue?

  A. Incorrect VLAN setting
  B. Insufficient DHCP scope
  C. Improper NIC setting
  D. Duplicate IP address
  B. Insufficient DHCP scope

• Question 1123:

  A company wants to implement a disaster recovery site for non-critical applications, which can tolerate a short period of downtime. Which of the following types of sites should the company implement to achieve this goal?

  A. Hot
  B. Cold
  C. warm
  D. Passive
  C. warm

  ---

  Explanation/Reference:

  The type of site that the company should implement for non-critical applications that can tolerate a short period of downtime is a warm site. A warm site is a disaster recovery site that has some pre-installed equipment and software, but not as much as a hot site, which is fully operational and ready to take over the primary site's functions in case of a disaster. A warm site requires some time and effort to activate and synchronize with the primary site, but not as much as a cold site, which has no equipment or software installed and requires a lot of configuration and testing. A passive site is not a common term for a disaster recovery site, but it could refer to a site that only receives backups from the primary site and does not actively participate in the network operations.

• Question 1124:

  A technician is troubleshooting a report about network connectivity issues on a workstation. Upon investigation, the technician notes the workstation is showing an APIPA address on the network interface. The technician verifies that the VLAN assignment is correct and that the network interface has connectivity.

  Which of the following is MOST likely the issue the workstation is experiencing?

  A. DHCP exhaustion
  B. A rogue DHCP server
  C. A DNS server outage
  D. An incorrect subnet mask
  A. DHCP exhaustion

  ---

  Explanation/Reference:

  DHCP exhaustion is a situation where the DHCP server runs out of available IP addresses to assign to clients. This can happen due to misconfiguration, malicious attacks, or high demand. When a client requests an IP address from the DHCP server and does not receive a response, it may resort to using an APIPA address, which is a self-assigned address in the range of 169.254.0.1 to 169.254.255.254. APIPA addresses are only valid for local communication and cannot access the internet or other networks. Therefore, a workstation showing an APIPA address indicates that it failed to obtain a valid IP address from the DHCP server, most likely due to DHCP exhaustion

• Question 1125:

  A network engineer is concerned about VLAN hopping happening on the network. Which of the following should the engineer do to address this concern?

  A. Configure private VLANS.
  B. Change the default VLAN.
  C. Implement ACLs on the VLAN.
  D. Enable dynamic ARP inspection.
  A. Configure private VLANS.

  ---

  Explanation/Reference:

  Private VLANs (PVLANs) segregate devices within the same VLAN, restricting their communication to enhance network security and isolation. To address concerns about VLAN hopping, configuring private VLANs (PVLANs) is an effective security measure. PVLANs restrict communication between devices within the same VLAN, preventing one device from "hopping" to another device's traffic within the same VLAN.

• Question 1126:

  Which of the following OSI model layers is where a technician would view UDP information?

  A. Physical
  B. Data link
  C. Network
  D. Transport
  D. Transport

  ---

  Explanation/Reference:

  Transport. The transport layer, specifically the User Datagram Protocol (UDP) is responsible for end-to-end communication and data transfer between applications on different devices. It's in this layer where a technician would view UDP information.

• Question 1127:

  A user took a laptop on a trip and made changes to the network parameters while at the airport. The user can access all internet websites but not corporate intranet websites. Which of the following is the most likely cause of the issue?

  A. Duplicate IP address
  B. Duplicate SSID
  C. Incorrect DNS
  D. Incorrect subnet mask
  C. Incorrect DNS

• Question 1128:

  Which of the following would be used to forward requests and replies between a DHCP server and client?

  A. Relay
  B. Lease
  C. Scope
  D. Range
  A. Relay

  ---

  Explanation/Reference:

  A relay would be used to forward requests and replies between a DHCP (Dynamic Host Configuration Protocol) server and client. In networking, a relay is a device that receives incoming messages and then forwards them to their destination. In the context of DHCP, a relay is a device that receives DHCP requests from clients on one network and then forwards them to the DHCP server on another network. This is useful when the client and server are not on the same network and cannot communicate directly. The relay helps to ensure that the client can still receive a valid IP address and other configuration information from the server.

• Question 1129:

  A network technician has identified a breach and is attempting to determine how the attacker connected to a device on the network. The technician uses tcpdump to perform a port scan and receives the following result:

  

  Which of the following describes how the attacker connected to the device?

  A. The attacker used Telnet.
  B. The attacker used VNC.
  C. The attacker used SSH.
  D. The attacker used RDP.
  C. The attacker used SSH.

• Question 1130:

  A corporation has a critical system that would cause unrecoverable damage to the brand if it was taken offline. Which of the following disaster recovery solutions should the corporation implement?

  A. Full backups
  B. Load balancing
  C. Hot site
  D. Snapshots
  C. Hot site

  ---

  Explanation/Reference:

  A hot site is the disaster recovery solution that the corporation should implement for its critical system that would cause unrecoverable damage to the brand if it was taken offline. A hot site is a fully operational backup site that can take over

  the primary site's functions in case of a disaster or disruption. A hot site has all the necessary hardware, software, data, network connections, and personnel to resume normal operations with minimal downtime. A hot site is suitable for

  systems that require high availability and cannot afford any data loss or interruption. References:
