CompTIA CompTIA Certifications N10-008 Questions & Answers

• Question 231:

  A local service provider connected 20 schools in a large city with a fiber-optic switched network. Which of the following network types did the provider set up?

  A. LAN

  B. MAN

  C. CAN

  D. WAN

  Correct Answer: B

  MAN stands for Metropolitan Area Network, and it is a type of network that covers a large geographic area, such as a city or a county. MANs are often used to connect multiple LANs (Local Area Networks) within a region, such as schools,

  offices, or government buildings. MANs typically use high-speed and high-capacity transmission media, such as fiber-optic cables, to provide fast and reliable data communication. MANs can also provide access to WANs (Wide Area

  Networks), such as the Internet, or other services, such as cable TV or VoIP.

  The other options are not correct because they are not the type of network that covers a large city. They are:

  LAN. LAN stands for Local Area Network, and it is a type of network that covers a small geographic area, such as a home, an office, or a building. LANs are often used to connect multiple devices, such as computers, printers, or phones,

  within a single network. LANs typically use low-cost and low-capacity transmission media, such as twisted-pair cables, to provide data communication. LANs can also provide access to other networks, such as MANs or WANs, through routers

  or gateways.

  CAN. CAN stands for Campus Area Network, and it is a type of network that covers a moderate geographic area, such as a university, a hospital, or a military base. CANs are often used to connect multiple LANs within a campus, such as

  different departments, buildings, or facilities. CANs typically use medium-cost and medium-capacity transmission media, such as coaxial cables, to provide data communication. CANs can also provide access to other networks, such as MANs

  or WANs, through routers or gateways.

  WAN. WAN stands for Wide Area Network, and it is a type of network that covers a very large geographic area, such as a country, a continent, or the world. WANs are often used to connect multiple MANs or LANs across different regions,

  such as different cities, states, or countries. WANs typically use high-cost and high- capacity transmission media, such as satellite links, to provide data communication. WANs can also provide access to various services, such as the Internet,

  email, or VPN.

• Question 232:

  A network technician must connect a newly installed access switch in a warehouse to the distribution switch in the telecommunications closet. The distance between the two switches is 1,640ft (500m). Which of the following is the best cable choice?

  A. Fiber

  B. Cat 5e

  C. Cat 6a

  D. Coaxial

  Correct Answer: A

  Fiber is the best cable choice for long distances, as it can transmit data over 1,640ft (500m) without significant signal loss or interference. Fiber is also immune to electromagnetic interference and can support higher bandwidths than copper cables. Cat 5e and Cat 6a are copper cables that have a maximum distance of 328ft (100m) for Ethernet networks. Coaxial cable is also a copper cable that can reach longer distances, but it is mainly used for cable TV and not for Ethernet networks.

• Question 233:

  A network administrator received complaints of intermittent network connectivity issues. The administrator investigates and finds that the network design contains potential loop scenarios. Which of the following should the administrator do?

  A. Enable spanning tree.

  B. Configure port security.

  C. Change switch port speed limits.

  D. Enforce 802. IQ tagging.

  Correct Answer: A

  Spanning tree is a protocol that prevents network loops by dynamically disabling or enabling switch ports based on the network topology. Network loops can cause intermittent connectivity issues, such as broadcast storms, MAC address

  table instability, and multiple frame transmission. By enabling spanning tree, the network administrator can ensure that there is only one active path between any two network devices at any given time.

• Question 234:

  Which of the following can be used to aggregate logs from different devices and would make analysis less difficult?

  A. Syslog

  B. SIEM

  C. Event logs

  D. NetFlow

  Correct Answer: B

  SIEM stands for Security Information and Event Management, and it is a system that collects, normalizes, and analyzes log data from different sources in a centralized platform. SIEM can help identify security incidents, monitor network performance, and generate reports and alerts. SIEM can make log analysis less difficult by providing a unified view of the log data, correlating events across different devices, and applying rules and filters to detect anomalies and patterns12.

• Question 235:

  An online gaming company needs a cloud solution that will allow for more virtual resources to be deployed when tournaments are held. The number of users who access the service increases during tournaments. The company also needs the resources to return to baseline levels once the resources are not needed in order to reduce cost. Which of the following cloud concepts would provide the best solution?

  A. Scalability

  B. Hybrid

  C. Multitenancy

  D. Elasticity

  Correct Answer: D

• Question 236:

  A network technician is troubleshooting a connectivity issue. All users within the network report that they are unable to navigate to websites on the internet; however, they can still access local network resources. The technician issues a command and receives the following results:

  

  Which of the following best explains the result of this command?

  A. Incorrect VLAN settings

  B. Upstream routing loop

  C. Network collisions

  D. DNS misconfiguration

  Correct Answer: B

  TTL expired in transit typically occurs when there is a routing loop in the network, causing packets to continually loop through routers without reaching their destination.

• Question 237:

  A network engineer is designing a secure communication link between two sites The entire data stream needs to remain confidential. Which of the following will achieve this goal?

  A. GRE

  B. IKE

  C. ESP

  D. AH

  Correct Answer: C

  ESP stands for Encapsulating Security Payload, and it is a protocol that provides confidentiality, integrity, and authentication for IP packets. ESP encrypts the payload of the IP packet, which contains the data stream, and adds a header and a trailer that contain security information. ESP can be used to create a secure communication link between two sites by using a VPN tunnel that protects the data stream from unauthorized access or modification. GRE stands for Generic Routing Encapsulation, and it is a protocol that encapsulates one network protocol inside another. GRE does not provide encryption or security by itself, but it can be combined with ESP or other protocols to create a secure VPN tunnel. IKE stands for Internet Key Exchange, and it is a protocol that negotiates and establishes security associations for IPsec, which is a suite of protocols that includes ESP and AH. IKE does not encrypt or protect the data stream, but it enables the secure exchange of keys and parameters for IPsec. AH stands for Authentication Header, and it is a protocol that provides integrity and authentication for IP packets. AH does not encrypt the payload of the IP packet, which means the data stream is not confidential. AH adds a header that contains security information and a checksum that verifies the integrity of the packet.

• Question 238:

  A technician is expanding a wireless network and adding new access points. The company requires that each access point broadcast the same SSID. Which of the following should the technician implement for this requirement?

  A. MIMO

  B. Roaming

  C. Channel bonding

  D. Extended service set

  Correct Answer: D

  An extended service set (ESS) is a wireless network that consists of two or more access points (APs) that share the same SSID and are connected by a distribution system, such as a switch or a router. An ESS allows wireless clients to roam seamlessly between different APs without losing connectivity or changing network settings. An ESS can also increase the coverage area and capacity of a wireless network

• Question 239:

  A company realizes that only half of its employees work in the office, and the employees who work from home no longer need a computer at the office. Which of the following security measures should the network administrator implement when removing a computer from a cubicle?

  A. Disable DHCP on the computer being removed.

  B. Place the switch port in a private VLAN.

  C. Apply a firewall rule to block the computer's IP address.

  D. Remove the employee's network access.

  Correct Answer: D
