CompTIA CompTIA Certifications N10-008 Questions & Answers

• Question 641:

  A company is reviewing ways to cut the overall cost of Its IT budget. A network technician suggests removing various computer programs from the IT budget and only providing these programs on an as- needed basis. Which of the following models would meet this requirement?

  A. Multitinency

  B. laaS

  C. SaaS

  D. VPN

  Correct Answer: C

  SaaS (Software as a Service). With SaaS, a company can subscribe to software applications that are hosted by a third-party provider and accessed over the internet. This model allows a company to pay only for what they use and provides flexibility to scale up or down as needed.

• Question 642:

  A network technician is troubleshooting a new web server connectivity issue. The network technician discovers the following on the support ticket

  1.

  The server's IP address can be pinged from the client PCs

  2.

  Access to the web resource works correctly when on the server's console.

  3.

  No clients can access the servers data via URL.

  4.

  The server does not have a firewall configured

  5.

  No ACLs are preventing connectivity from the client's network. All services on the server are operating normally, which was confirmed by the server team.

  Which of the following actions will resolve the issue?

  A. Reset port security on the switchport connecting the server.

  B. Adjust the web server's NTP settings to match the client settings.

  C. Configure A records for the web server.

  D. Install the correct MIB on the web server

  Correct Answer: C

• Question 643:

  A customer wants to log in t o a vendor's server using a web browser on a laptop. Which of the following would require the LEAST configuration to allow encrypted access to the server?

  A. Secure Sockets Layer

  B. Site-to-site VPN

  C. Remote desktop gateway

  D. Client-to-site VPN

  Correct Answer: A

  Secure Sockets Layer (SSL) would require the least configuration to allow encrypted access to the server. SSL is a protocol used for secure communication over the internet and is widely used for web applications. By enabling SSL on the vendor's server, the customer can access it securely using a web browser without requiring additional configurations such as setting up a VPN or remote desktop gateway.

• Question 644:

  A network administrator is getting reports of some internal users who cannot connect to network resources. The users slate they were able to connect last week, but not today. No changes have been configured on the network devices or server during the last few weeks. Which of the following is the MOST likely cause of the issue?

  A. The client DHCP scope is fully utilized

  B. The wired network is experiencing electrical interference

  C. The captive portal is down and needs to be restarted

  D. SNMP traps are being received

  E. The packet counter on the router interface is high.

  Correct Answer: A

  The issue because if the DHCP scope is fully utilized, it means there are no more available IP addresses for new devices to receive and connect to the network. This could prevent internal users from connecting to network resources.

• Question 645:

  A technician wants to monitor and provide traffic segmentation across the network. The technician would like to assign each department a specific identifier. Which of the following will the technician MOST likely use?

  A. Flow control

  B. Traffic shaping

  C. VLAN fagging

  D. Network performance baselines

  Correct Answer: C

  To monitor and provide traffic segmentation across the network, a technician may use the concept of VLANs (Virtual Local Area Networks). VLANs are a way of dividing a single physical network into multiple logical networks, each with its own unique identifier or "tag."

  By assigning each department a specific VLAN identifier, the technician can segment the network traffic and ensure that the different departments' traffic is kept separate from one another. This can help to improve network security, performance, and scalability, as well as allowing for better monitoring and control of the network traffic.

  To implement VLANs, the technician will need to configure VLAN tagging on the network devices, such as switches and routers, and assign each department's devices to the appropriate VLAN. The technician may also need to configure VLAN trunking to allow the different VLANs to communicate with each other.

  By using VLANs, the technician can effectively monitor and segment the network traffic, providing better control and visibility into the network.

• Question 646:

  After rebooting an AP a user is no longer able to conned to me enterprise LAN A technician plugs a laptop In to the same network jack and receives the IP 169.254 0 200. Which of the following is MOST likely causing the issue?

  A. DHCP scope exhaustion

  B. Signal attenuation

  C. Channel overlap

  D. Improper DNS configuration

  Correct Answer: A

  DHCP scope exhaustion occurs when the number of available IP addresses to be leased from a DHCP server have been used up. This could be caused by a large number of clients on the network, or a misconfigured DHCP scope. When this happens, clients will be assigned an IP address from the APIPA range (169.254.0.0 to 169.254.255.255). To resolve this issue, the DHCP scope needs to be expanded or adjusted to accommodate the number of clients on the network.

• Question 647:

  Which of the following layers of the OSI model has new protocols activated when a user moves from a wireless to a wired connection?

  A. Data link

  B. Network

  C. Transport

  D. Session

  Correct Answer: A

  "The Data Link layer also determines how data is placed on the wire by using an access method. The wired access method, carrier-sense multiple access with collision detection (CSMA/CD), was once used by all wired Ethernet networks, but is automatically disabled on switched full-duplex links, which have been the norm for decades. Carrier- sense multiple access with collision avoidance (CSMA/CA) is used by wireless networks, in a similar fashion."

• Question 648:

  A technician is investigating an issue with connectivity at customer's location. The technician confirms that users can access resources locally but not over the internet The technician theorizes that the local router has failed and investigates further. The technician's testing results show that the route is functional: however, users still are unable to reach resources on the internal.

  Which of the following describes what the technician should do NEXT?

  A. Document the lessons learned

  B. Escalate the issue

  C. identify the symptoms.

  D. Question users for additional information

  Correct Answer: B

  Among the options given, B is indeed the one conforming to CompTIA's methodology. C and D should have been done exhaustively in the first place. A comes last after a solution has been shown to work.

• Question 649:

  A network device needs to discover a server that can provide it with an IPv4 address. Which of the following does the device need to send the request to?

  A. Default gateway

  B. Broadcast address

  C. Unicast address

  D. Link local address

  Correct Answer: B

  The DHCP client sends broadcast request packets to the network; the DHCP servers respond with broadcast packets that offer IP parameters, such as an IP address for the client. After the client chooses the IP parameters, communication

  between the client and server is by unicast packets.

  "When a DHCP client boots up, it automatically sends out a DHCP Discover UDP datagram to the broadcast address, 255.255.255.255. This DHCP Discover message asks "Are there any DHCP servers out there?" The client can't send

  unicast traffic yet, as it doesn't have a valid IP address that can be used."

• Question 650:

  Which of the following ports should be used to securely receive mail that is synchronized across multiple devices?

  A. 25

  B. 110

  C. 443

  D. 993

  Correct Answer: D
