CompTIA N10-008 Online Questions & Answers

• Question 201:

  A company has a geographically remote office concern for this type of connection?

  A. Duplex
  B. Collisions
  C. Jitter
  D. Encapsulation
  C. Jitter

  ---

  Explanation/Reference:

  Jitter is the variation in the delay of packets arriving at a destination. Jitter can cause problems for real-time applications, such as voice and video, that require consistent and smooth delivery of packets. A geographically remote office that connects to the main office via a WAN link may experience high jitter due to factors such as network congestion, routing changes, or link quality. Jitter can be reduced by using quality of service (QoS) mechanisms that prioritize and shape traffic according to its importance and sensitivity.

• Question 202:

  A network administrator is installing a new server in the data center. The administrator is concerned the amount of traffic generated will exceed 1GB. and higher-throughput NiCs are not available for installation. Which of the following is the BEST solution for this issue?

  A. Install an additional NIC and configure LACP.
  B. Remove some of the applications from the server.
  C. Configure the NIC to use fun duplex
  D. Configure port mirroring to send traffic to another server.
  E. Install a SSD to decrease data processing time.
  A. Install an additional NIC and configure LACP.

• Question 203:

  Which of the following types of devices can provide content filtering and threat protection, and manage multiple IPSec site-to-site connections?

  A. Layer 3 switch
  B. VPN headend
  C. Next-generation firewall
  D. Proxy server
  E. Intrusion prevention
  C. Next-generation firewall

• Question 204:

  A network administrator needs to change where the outside DNS records are hosted. Which of the following records should the administrator change at the registrar to accomplish this task?

  A. NS
  B. SOA
  C. PTR
  D. CNAME
  A. NS

  ---

  Explanation/Reference:

  NS stands for Name Server, and it is a DNS record that specifies which servers are authoritative for a domain. The registrar is the entity that manages the domain registration and delegation, and it maintains the NS records for each domain. To change where the outside DNS records are hosted, the network administrator needs to change the NS records at the registrar to point to the new DNS servers that will host the outside DNS records.

• Question 205:

  Which of the following is a security flaw in an application or network?

  A. A threat
  B. A vulnerability
  C. An exploit
  D. A risk
  B. A vulnerability

  ---

  Explanation/Reference:

  A vulnerability is a security flaw in an application or network that can be exploited by an attacker, allowing them to gain access to sensitive data or take control of the system. Vulnerabilities can range from weak authentication methods to unpatched software, allowing attackers to gain access to the system or data they would not otherwise be able to access. Exploits are programs or techniques used to take advantage of vulnerabilities, while threats are potential dangers, and risks are the likelihood of a threat becoming a reality.

• Question 206:

  Which of the following would most likely affect design considerations when building out an IDF?

  A. The source panel amperage
  B. The fire suppression system
  C. The humidity levels
  D. The cable transmission speeds
  B. The fire suppression system

  ---

  Explanation/Reference:

  The fire suppression system is a design consideration when building out an IDF because it can affect the safety and reliability of the network equipment and cabling. A fire suppression system is a system that detects and extinguishes fires in a

  building, using water, gas, or chemicals. Depending on the type of fire suppression system, it can have different impacts on the IDF design, such as:

  Water-based systems, such as sprinklers, can damage the network equipment and cabling if they are activated by a fire or a false alarm. Therefore, the IDF should be designed to protect the equipment and cabling from water exposure, such

  as using waterproof cabinets, drip pans, and conduits.

  Gas-based systems, such as clean agent systems, can displace the oxygen in the IDF and cause suffocation for anyone inside. Therefore, the IDF should be designed to allow for ventilation and air circulation, as well as warning signs and

  alarms to alert anyone in the IDF before the gas is released. Chemical-based systems, such as dry chemical systems, can leave a residue on the network equipment and cabling that can affect their performance and lifespan. Therefore, the

  IDF should be designed to minimize the contact between the chemical and the equipment and cabling, as well as provide a means for cleaning and restoring them after a fire.

  The other options are not correct because:

  The source panel amperage is not a design consideration when building out an IDF, as it is determined by the electrical circuit and the power needs of the network equipment and cabling. The source panel amperage does not affect the

  layout, location, or protection of the IDF.

  The humidity levels are not a design consideration when building out an IDF, as they are controlled by the HVAC system and the ventilation of the IDF. The humidity levels do not affect the layout, location, or protection of the IDF. The cable transmission speeds are not a design consideration when building out an IDF, as they are determined by the type and quality of the network cabling and the network equipment. The cable transmission speeds do not affect the layout, location, or protection of the IDF.

• Question 207:

  Which of the following fouling protocols is generally used by major ISPs for handing largescale internet traffic?

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

• Question 208:

  A Chief Information Officer wants to monitor network breaching in a passive, controlled manner. Which of the following would be BEST to implement?

  A. Honeypot
  B. Perimeter network
  C. Intrusion prevention system
  D. Port security
  A. Honeypot

  ---

  Explanation/Reference:

  A honeypot is a computer system that is intentionally exposed to attack in order to gather information about attackers. Honeypots are often used to monitor network breaches in a passive, controlled manner.

• Question 209:

  A Chief Executive Officer and a network administrator came to an agreement with a vendor to purchase new equipment for the data center. A document was drafted so all parties would be informed about the scope of the project before it started. Which of the following terms BEST describes the document used?

  A. Contract
  B. Project charter
  C. Memorandum of understanding
  D. Non-disclosure agreement
  C. Memorandum of understanding

• Question 210:

  A network administrator is working to configure a new device to provide Layer 2 connectivity to various endpoints including several WAPs. Which of the following devices will the administrator MOST likely configure?

  A. WLAN controller
  B. Cable modem
  C. Load balancer
  D. Switch
  E. Hub
  D. Switch

  ---

  Explanation/Reference:

  A switch is a device that provides Layer 2 connectivity to various endpoints by forwarding frames based on MAC addresses. A switch can also connect to several WAPs (wireless access points) to provide wireless connectivity to wireless devices.
