質問 # 131
Company C is acquiring Company A and Company B. Company C needs to merge all three networks into one Class B network. Additionally, the network capacity of each company needs to grow by 20%. Company C also requires segmentation of Company A and Company B to account for unknown security vulnerabilities within each.
Instructions:
Select the correct subnet range to meet Company C ' s requirements.
正解：
解説：
Explanation:
A = 192.168.10.0/26
B = 192.168.1.0/23
C = 10.0.0.1/18
Using the choices shown in the screenshot, the best-fit subnet selections are based on host growth requirements first, then segmentation .
For Company A , the current device count is 32 . With 20% growth , that becomes about 39 devices . A /27 only supports 30 usable hosts , so it is too small. A /26 supports 62 usable hosts , so 192.168.10.0/26 is the correct choice.
For Company B , the current device count is 100 . With 20% growth , that becomes 120 devices . The smallest correct subnet would normally be a /25 with 126 usable hosts , but that option is not shown. From the available choices, 192.168.1.0/23 is the smallest subnet that still supports more than 120 hosts, so that is the best answer.
For Company C , the current device count is 10,000 . With 20% growth , it needs space for 12,000 hosts . A
/18 provides 16,382 usable hosts , while a /19 is not available and a /21 or /22 would be far too small.
Therefore, 10.0.0.1/18 is the correct selection.
One important note: the dropdown choices shown do not actually let all three companies be placed into a single true Class B network block. So these answers are the best valid selections from the provided options .
質問 # 132
A support agent receives a report that a remote user's wired devices are constantly disconnecting and have slow speeds. Upon inspection, the support agent sees that the user's coaxial modern has a signal power of -97 dB.
正解：B
解説：
A signal power of -97dB indicates a very weak signal, which can cause connectivity issues and slow speeds.
Splitters on a coaxial line can degrade the signal quality further, so removing them can help improve the signal strength and overall connection quality.
* Signal Quality: Splitters can reduce the signal strength by dividing the signal among multiple lines, which can be detrimental when the signal is already weak.
* Direct Connection: Ensuring a direct connection from the modem to the incoming line can maximize signal quality and reduce potential points of failure.
Network References:
* CompTIA Network+ N10-007 Official Certification Guide: Discusses troubleshooting connectivity issues and the impact of signal strength on network performance.
* Cisco Networking Academy: Provides insights on maintaining optimal signal quality in network setups.
* Network+ Certification All-in-One Exam Guide: Covers common network issues, including those related to signal degradation and ways to mitigate them.
質問 # 133
You have been tasked with implementing an ACL on the router that will:
1. Permit the most commonly used secure remote access technologies from the management network to all other local network segments
2. Ensure the user subnet cannot use the most commonly used remote access technologies in the Linux and Windows Server segments.
3. Prohibit any traffic that has not been specifically allowed.
INSTRUCTIONS
Use the drop-downs to complete the ACL

質問 # 134
A help desk technician receives a report that users cannot access internet URLs. The technician performs ping tests and finds that sites fail when a URL is used but succeed when an IP is used. Which of the following tools should the technician utilize next?
正解：B
解説：
Other tools are less relevant here:
A). tcpdump is a packet analyzer and is more advanced for deeper traffic analysis.
B). tracert is used to trace the route to a destination, not ideal for DNS issues.
C). nmap is a port scanner and network mapper, not for resolving DNS problems.
D). dig (Domain Information Groper) is a DNS lookup tool used to troubleshoot DNS problems by querying name servers directly.
Reference:
CompTIA Network+ N10-009 Official Objectives: 5.1 - Given a scenario, use the appropriate network troubleshooting tools.
Explanation:
The issue is clearly related to DNS resolution, as IP-based connections succeed but domain name-based ones fail.
質問 # 135
Which of the following best describes the transmission format that occurs at the transport layer over connectionless communication?
正解：D
解説：
At the transport layer, connectionless communication is typically handled using the User Datagram Protocol (UDP), which transmits data in units called datagrams. Unlike TCP, UDP does not establish a connection before sending data and does not guarantee delivery, making datagrams the correct term for the transmission format in this context. Reference: CompTIA Network+ Exam Objectives and official study guides.
