• Question 1111:

  Which of the following is the most accurate NTP time source that is capable of being accessed across a network connection?

  A. Stratum 0 device
  B. Stratum 1 device
  C. Stratum 7 device
  D. Stratum 16 device
  B. Stratum 1 device

  ---

  Explanation/Reference:

  NTP (Network Time Protocol) is a protocol that synchronizes the clocks of network devices with a reference time source. NTP uses a hierarchical system of time sources, called strata, to distribute the time information. A stratum 0 device is

  the most accurate time source, such as an atomic clock or a GPS receiver, but it is not directly accessible across a network connection. A stratum 1 device is a network device that is directly connected to a stratum 0 device, such as a

  dedicated NTP server or a router with a GPS antenna, and it acts as a primary time server for other network devices. A stratum 2 device is a network device that synchronizes its time with a stratum 1 device, and so on. The higher the stratum

  number, the lower the accuracy and reliability of the time source. A stratum 16 device is a network device that has no valid time source and is considered unsynchronized.

  Part 1 of current page talks about how Bing is your AI-powered copilot for the web and provides various examples of how it can help you with different tasks, such as writing a joke, creating a table, or summarizing research. However, it does

  not mention anything about NTP or time sources.

  Part 2 of current page shows the search results for "ai powered search bing chat", which include web, image, and news results. However, none of these results seem to be relevant to the question, as they are mostly about Bing's features,

  products, or announcements, not about NTP or time sources.

  Therefore, I cannot find the answer or the explanation from the current page. I have to use my own knowledge and information from other sources to verify the answer and provide a short but comprehensive explanation. I will cite these

  sources using numerical references.

• Question 1112:

  Which of the following authentication protocols should be used when securing a basic wireless network? (Select two).

  A. WPA2
  B. RDP
  C. WPA
  D. SSL
  E. SNMP
  F. EAP
  A. WPA2
  C. WPA

• Question 1113:

  Which of the following services provides the network information for the address when IPv6 is used for SLAAC addressing?

  A. EUI-64
  B. IPv6 unicast routing
  C. Router advertisement
  D. DHCPv6
  C. Router advertisement

  ---

  Explanation/Reference:

  Router advertisement is part of the Neighbor Discovery Protocol (NDP) in IPv6 and is used in Stateless Address Autoconfiguration (SLAAC) to provide network information to IPv6 hosts. Router advertisements inform hosts about the presence of routers, network prefixes for address configuration, and various other parameters necessary for the host to configure its IPv6 address and connect to the IPv6 network. This mechanism allows IPv6 devices to automatically configure themselves with an IPv6 address and other related network information without the need for a DHCPv6 server, although DHCPv6 can be used alongside SLAAC for additional configuration options like DNS server addresses.

• Question 1114:

  A consultant is working with two international companies. The companies will be sharing cloud resources for a project.

  Which of the following documents would provide an agreement on how to utilize the resources?

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

• Question 1115:

  A network administrator wants to install new VoIP switches in small network closet but is concerned about the current heat level of the room. Which of the following should the administrator take into consideration before installing the new equipment?

  A. The power load of the switches
  B. The humidity in the room
  C. The fire suppression system D. The direction of airflow within the switches
  D

• Question 1116:

  The following configuration is applied to a DHCP server connected to a VPN concentrator:

  

  There are 300 non-concurrent sales representatives who log in for one hour a day to upload reports, and 252 of these representatives are able to connect to the VPN without any Issues. The remaining sales representatives cannot connect to the VPN over the course of the day.

  Which of the following can be done to resolve the issue without utilizing additional resources?

  A. Decrease the lease duration
  B. Reboot the DHCP server
  C. Install a new VPN concentrator
  D. Configure a new router
  A. Decrease the lease duration

  ---

  Explanation/Reference:

  Decrease the lease duration - They're exhausting all of the available IP addresses in the DHCP scope for VPN clients. Excluding the network address (10.0.0.0), DHCP server (10.0.0.1) and gateway IP (10.0.0.254), the DHCP scope that the server can give out would range from 10.0.0.2 to 10.0.0.253. This would be 252 usable addresses, which the number of representatives that were able to connect. This isn't enough for all 300 sales representatives, so decreasing the lease duration would make sense here since they only login for an hour a day to upload reports.

• Question 1117:

  Two companies want to build an encrypted tunnel between them and use a PSK for initial authentication. Which of the following is the BEST protocol for the companies to use?

  A. VPN
  B. SSL
  C. TLS
  D. IPSec
  D. IPSec

• Question 1118:

  Which of the following indicates a computer has reached end-of-support?

  A. The computer does not have any users.
  B. The antivirus protection is expired.
  C. The operating system license is expired.
  D. No more patches or bug fixes are available indefinitely.
  D. No more patches or bug fixes are available indefinitely.

  ---

  Explanation/Reference:

  No more patches or bug fixes are available indefinitely. This indicates that a computer has reached end-of-support, which means that the manufacturer or vendor of the hardware or software no longer provides technical assistance, updates, or security fixes for the product12. This can expose the computer to potential security risks and compatibility issues with newer technologies

• Question 1119:

  A network administrator is configuring logging on an edge switch. The requirements are to log each time a switch port goes up or down. Which of the following logging levels will provide this information?

  A. Warnings
  B. Notifications
  C. Alert
  D. Errors
  B. Notifications

  ---

  Explanation/Reference:

  Notifications are the lowest logging level and will provide the desired information regarding switch port up/down activity. According to the CompTIA Network+ Study Manual, notifications "are used for logging normal activities, such as port up/ down events, link changes, and link flaps."

• Question 1120:

  A branch office is experiencing frequent power-related issues that are taking the network down dally. Which of the following would best address this network uptime issue?

  A. MPLS
  B. IPS
  C. PDU
  D. UPS
