CompTIA N10-008 Online Questions & Answers

• Question 131:

  Which of the following technologies provides a failover mechanism for the default gateway?

  A. FHRP
  B. LACP
  C. OSPF
  D. STP
  A. FHRP

• Question 132:

  A network administrator responds to a support ticket that was submitted by a customer who is having issues connecting to a website inside of the company network The administrator verities that the customer could not connect to a website

  using a URL.

  Which of the following troubleshooting steps would be BEST for the administrator to take?

  A. Check for certificate issues
  B. Contact the ISP
  C. Attempt to connect to the site via IP address
  D. Check the NTP configuration.
  C. Attempt to connect to the site via IP address

  ---

  Explanation/Reference:

  The best option for the administrator to take would be to attempt to connect to the site via IP address. This will help to determine if the issue is related to the website's DNS address or if the site itself is not accessible. Checking for certificate issues may be necessary, but this should be done after the administrator has attempted to connect to the site via IP address. Contacting the ISP is unnecessary since the issue is related to the website inside of the company network, and checking the NTP configuration is not relevant to this issue.

  When a customer is having issues connecting to a website using a URL, one of the first troubleshooting steps a network administrator should take is attempting to connect to the site using the IP address of the website. This will help to determine if the issue is related to a DNS resolution problem or a connectivity problem. If the administrator is able to connect to the website using the IP address, then the issue may be related to a DNS problem. However, if the administrator is still unable to connect, then the issue may be related to a connectivity problem. In either case, further troubleshooting steps will be necessary. Checking for certificate issues or NTP configuration, and contacting the ISP would not be the BEST initial steps in this scenario.

• Question 133:

  A company wants to mitigate unauthorized physical connectivity after implementing a hybrid work schedule. Which of the following will the company MOST likely configure?

  A. Intrusion prevention system
  B. DHCP snooping
  C. ARP inspection
  D. Port security
  D. Port security

  ---

  Explanation/Reference:

  Port security is a feature that allows network administrators to control which devices can connect to specific switch ports. By configuring port security, the company can limit the number of authorized devices that can be connected to each switch port, preventing unauthorized physical connectivity.

• Question 134:

  Which of the following should a technician use to keep the STP topology predictable and consistent?

  A. Root guard
  B. Flood guard
  C. Dynamic ARP inspection
  D. Ingress ACLs
  A. Root guard

• Question 135:

  A technician is installing a new fiber connection to a network device in a datacenter. The connection from the device to the switch also traverses a patch panel connection. The chain of connections is in the following order:

  1.

  Device

  2.

  LC/LC patch cable

  3.

  Patch panel

  4.

  Cross-connect fiber cable

  5.

  Patch panel

  6.

  LC/LC patch cable

  7.

  Switch

  The connection is not working. The technician has changed both patch cables with known working patch cables. The device had been tested and was working properly before being installed. Which of the following is the MOST likely cause of the issue?

  A. TX/RX is reversed
  B. An incorrect cable was used
  C. The device failed during installation
  D. Attenuation is occurring
  A. TX/RX is reversed

  ---

  Explanation/Reference:

  TX/RX is reversed since it makes the sense to me given the other options:

  If the TX (transmit) and RX (receive) fibers are reversed in either of the LC/LC patch cables or the cross-connect fiber cable, the data will not be transmitted and received correctly, resulting in a connection failure. Also, I think the question listed the order of the connections and multiple patch panels to suggest that there was good chance of some kind of misalignment going on when the fibers were installed.

• Question 136:

  A network technician wants to deploy a new wireless access point to reduce user latency. Currently, the organization has the following deployed: Which of the following channels should the new device broadcast on?

  A. Channel 3
  B. Channel 9
  C. Channel 10
  D. Channel 11
  D. Channel 11

  ---

  Explanation/Reference:

  The best channel for a new wireless access point is one that does not overlap with the existing channels used by other devices. Overlapping channels can cause interference and degrade the performance of the wireless network. According to the web search results, the 2.4 GHz band has 11 channels in the U.S., but only channels 1, 6, and 11 are non- overlapping. Since the existing devices are using channels 1 and 6, the new device should use channel 11 to avoid adjacent-channel interference12

• Question 137:

  A technician has completed configuration on a new satellite location. The location has a new firewall and a small internal network. The technician has been asked to perform basic vulnerability testing. Which of the following tools would BEST assist the technician in verifying the security of the site?

  A. Packet sniffer
  B. Bandwidth tester
  C. Port scanner
  D. Protocol analyzer
  D. Protocol analyzer

• Question 138:

  A network administrator needs to implement a solution to mediate access to the internet- Which of the following should the administrator most likely implement?

  A. Router
  B. Cloud gateway
  C. proxy
  D. Intrusion prevention system
  C. proxy

  ---

  Explanation/Reference:

  A proxy is a solution that can mediate access to the internet. A proxy is a server that acts as an intermediary between a client and a destination server on the internet. A proxy can perform various functions, such as filtering, caching, logging, or modifying requests and responses. A proxy can help improve network performance, security, and privacy by reducing bandwidth consumption, blocking malicious or unwanted content, monitoring network activity, and hiding the client's identity or location.

• Question 139:

  A customer hired a network consultant to install a new wireless network with the following specifications:

  2.4GHz 11Mbps 20MHz

  Which of the following standards best fits these requirements?

  A. 802.11ac
  B. 802.11b
  C. 802.11g
  D. 802.11n
  B. 802.11b

  ---

  Explanation/Reference:

  The 802.11b standard is a wireless networking protocol that operates in the 2.4GHz frequency band and supports a maximum data rate of 11Mbps. It uses a 20MHz channel width and a direct-sequence spread spectrum (DSSS) modulation technique2. The 802.11b standard was released in 1999 and is backward compatible with the original 802.11 standard3. The other standards do not match the specifications given by the customer. 802.11ac operates in the 5GHz band and supports higher data rates up to 6.9Gbps. 802.11g also operates in the 2.4GHz band but supports data rates up to 54Mbps. 802.11n can operate in both 2.4GHz and 5GHz bands and supports data rates up to 600Mbps. It also uses a wider channel width of 40MHz and a multiple-input multiple-output (MIMO) technology3.

• Question 140:

  Which of the following documents dictates the uptimes that were agreed upon by the involved parties?

  A. MOU
  B. BYOD
  C. SLA
  D. NDA
  C. SLA

  ---

  Explanation/Reference:

  An SLA (Service Level Agreement) is a document that defines the expected level of service and performance guaranteed by a service provider to a customer. It usually specifies metrics such as uptime, availability, reliability, response time, and compensation or penalties for not meeting the agreed standards. An SLA is a way of ensuring that both parties are clear about their roles and responsibilities, and that the customer receives the quality of service they paid for.
