CompTIA N10-008 Online Questions & Answers

• Question 141:

  When internal users attempt to access the company website, they are redirected to an inappropriate website. Which of the following is this scenario an example of?

  A. DNS poisoning
  B. On-path attack
  C. VLAN hopping
  D. ARP spoofing
  A. DNS poisoning

  ---

  Explanation/Reference:

  Domain Name System (DNS) poisoning happens when fake information is entered into the cache of a domain name server, resulting in DNS queries producing an incorrect reply, sending users to the wrong website. DNS poisoning also goes by the terms "DNS spoofing" and "DNS cache poisoning."

• Question 142:

  An administrator is adjusting the routing policy to ensure the headquarters location can connect to a new out-of-state branch office via BGP. Which of the following types of networks is being described?

  A. PAN
  B. MAN
  C. LAN
  D. WAN
  D. WAN

  ---

  Explanation/Reference:

  The scenario describes a Wide Area Network (WAN), which connects multiple local area networks (LANs) across geographically dispersed locations, such as between a headquarters and a new out-of-state branch office. WANs typically use technologies like Border Gateway Protocol (BGP) to manage the exchange of routing and reachability information between large networks on the internet.

• Question 143:

  Which of the following technologies can be implemented on network devices to increase throughput in network storage systems?

  A. Trunking
  B. Frame Relay
  C. Jumbo frames
  D. InfiniBand
  C. Jumbo frames

• Question 144:

  Which of the following is most likely responsible for the security and handling of personal data in Europe?

  A. GDPR
  B. SCADA
  C. SAML
  D. PCI DSS
  A. GDPR

  ---

  Explanation/Reference:

  GDPR stands for General Data Protection Regulation, which is a European Union regulation on information privacy and security. It applies to any organization that collects or processes personal data of individuals in the EU, and it sets out rules and requirements for data protection, consent, breach notification, and enforcement1 References1: https://en.wikipedia.org/wiki/General_Data_Protection_Regulation

• Question 145:

  A network technician at a university is assisting with the planning of a simultaneous software deployment to multiple computers in one classroom in a building. Which of the following would be BEST to use?

  A. Multicast
  B. Anycast
  C. Unicast
  D. Broadcast
  A. Multicast

  ---

  Explanation/Reference:

  Multicast would be the BEST to use in this scenario.

  Multicast is a method of transmitting a single copy of data to a group of destinations on a network simultaneously. It allows a source to send a single copy of data to a specific group of hosts, rather than sending a separate copy of the data to

  each individual host. This is an efficient way to deploy software to multiple computers in one classroom, as it reduces network traffic and ensures that all computers receive the software update at the same time.

• Question 146:

  A company with multiple routers would like to implement an HA network gateway with the least amount of downtime possible. This solution should not require changes on the gateway setting of the network clients. Which of the following should a technician configure?

  A. Automate a continuous backup and restore process of the system's state of the active gateway.
  B. Use a static assignment of the gateway IP address on the network clients.
  C. Configure DHCP relay and allow clients to receive a new IP setting.
  D. Configure a shared VIP and deploy VRRP on the routers.
  D. Configure a shared VIP and deploy VRRP on the routers.

  ---

  Explanation/Reference:

  The open standard protocol Virtual Router Redundancy Protocol (VRRP) is similar to HSRP, the differences mainly being in terminology and packet formats. In VRRP, the active router is known as the master, and all other routers in the group are known as backup routers. There is no specific standby router; instead, all backup routers monitor the status of the master, and in the event of a failure, a new master router is selected from the available backup routers based on priority

• Question 147:

  Which of the following devices Is used to configure and centrally manage access points Installed at different locations?

  A. Wireless controller
  B. Load balancer
  C. Proxy server
  D. VPN concentrator
  A. Wireless controller

  ---

  Explanation/Reference:

  A wireless controller is a device that is used to centrally manage wireless access points (APs) that are installed at different locations. It allows an administrator to configure and manage the APs remotely, rather than having to configure each AP individually. A wireless controller can be used to control multiple APs and can provide features such as load balancing, security, and guest access.

• Question 148:

  Which of the following is MOST commonly used to address CVEs on network equipment and/or operating systems?

  A. Vulnerability assessment
  B. Factory reset
  C. Firmware update
  D. Screened subnet
  C. Firmware update

  ---

  Explanation/Reference:

  Firmware is a type of software that controls the low-level functions of a hardware device, such as a router, switch, printer, or camera. Firmware updates are patches or upgrades that fix bugs, improve performance, add features, or address security vulnerabilities in firmware. Firmware updates are commonly used to address CVEs (Common Vulnerabilities and Exposures) on network equipment and operating systems, as CVEs are publicly known flaws that can be exploited by attackers.

• Question 149:

  A company that uses VoIP telephones is experiencing intermittent issues with one-way audio and dropped conversations The manufacturer says the system will work if ping times are less than 50ms. The company has recorded the following ping times:

  

  Which of the following is MOST likely causing the issue?

  A. Attenuation
  B. Latency
  C. VLAN mismatch
  D. Jitter
  D. Jitter

  ---

  Explanation/Reference:

  Jitter is most likely causing the issue of intermittent one-way audio and dropped conversations for the company that uses VoIP telephones. Jitter is a variation in delay of packets arriving at the destination. It can cause choppy or distorted audio quality for VoIP applications, especially over WAN links that have limited bandwidth and high latency. The recommended jitter for VoIP is less than 10ms1. The company has recorded ping times that exceed 50ms, which indicates high jitter and latency on their network. References: https://www.voip-info.org/voip-jitter/

• Question 150:

  Which of the following is the most likely reason an insurance brokerage would enforce VPN usage?

  A. To encrypt sensitive data in transit
  B. To secure the endpoints
  C. To maintain contractual agreements
  D. To comply with data retention requirements
  A. To encrypt sensitive data in transit

  ---

  Explanation/Reference:

  The most likely reason an insurance brokerage would enforce VPN usage is to encrypt sensitive data in transit. A VPN (Virtual Private Network) is a technology that creates a secure and encrypted tunnel between two or more devices over a public network, such as the internet. A VPN allows users to access remote resources or services as if they were on the same private network, while protecting their data from interception, modification, or spoofing by malicious actors. An insurance brokerage would use a VPN to protect the confidentiality and integrity of sensitive data, such as customer information, financial records, or insurance policies, that are transmitted over the internet.
