CompTIA Network+ Certification Exam 認定 N10-009 試験問題 (Q425-Q430):質問 # 425
A network engineer connects a business to a new ISP. A simple ping test to 8.8.8.8 is successful. However, users complain of extreme slowness to any website and periods of no connectivity. Which of the following is the most likely cause?
  • A. Subnet mask configuration
  • B. Incorrect default gateway
  • C. VLAN mismatch
  • D. Duplicate ISP IP address
正解：D
解説：
If the business shares or duplicates the ISP-assigned public IP address, routing instability and conflicts will occur. Pinging a public IP like 8.8.8.8 may work (since ICMP can bypass certain conflicts), but browsing websites (which requires stable sessions and return traffic) will fail intermittently.
A). If the default gateway were incorrect, no external connectivity would work at all.
B). VLAN mismatch is an internal issue, not affecting ISP routing.
C). Subnet mask misconfiguration would prevent consistent routing but usually blocks ping too.

質問 # 426
A secure communication link needs to be configured between data centers via the internet. The data centers are located in different regions. Which of the following is the best protocol for the network administrator to use?
  • A. DCI
  • B. IPSec
  • C. GRE
  • D. VXLAN
正解：B
解説：
IPSec (Internet Protocol Security) is the best choice for secure communication over the internet, as it provides encryption, authentication, and data integrity. It is widely used in VPNs and site-to-site secure tunnels.
Breakdown of Options:
A: DCI (Data Center Interconnect) - A general term for linking data centers, but it doesn't specify a secure tunneling protocol.
B: GRE (Generic Routing Encapsulation) - Encapsulates traffic but lacks encryption, making it less secure than IPSec.
C: VXLAN (Virtual Extensible LAN) - Used for Layer 2 network overlays, not for securing communication over the internet.
D: IPSec - # Correct answer. Provides encryption, authentication, and integrity for data over the internet.

See the answer and solution below
Explanation:
Network Health:
WAN 2 appears to have a lower average latency and loss percentage, which would make it the preferred WAN station for VoIP traffic. VoIP traffic requires low latency and packet loss to ensure good voice quality and reliability. WAN 1 seems to have higher RAM and processor usage, which could also affect the performance of VoIP traffic.
Here's the summary of the key metrics for WAN 1 and WAN 2 from the image provided:
WAN 1:
Uplink Speed: 10G
Total Usage: 26.969GB Up / 1.748GB Down
Average Throughput: 353MBps Up / 23.42MBps Down
Loss: 2.51%
Average Latency: 24ms
Jitter: 9.5ms
WAN 2:
Uplink Speed: 1G
Total Usage: 930GB Up / 138GB Down
Average Throughput: 12.21MBps Up / 1.82MBps Down
Loss: 0.01%
Average Latency: 11ms
Jitter: 3.9ms
For VoIP traffic, low latency and jitter are particularly important to ensure voice quality. While WAN 1 has higher bandwidth and throughput, it also has higher latency and jitter compared to WAN 2. However, WAN 2 has much lower loss, lower latency, and lower jitter, which are more favorable for VoIP traffic that is sensitive to delays and variation in packet arrival times.
Given this information, WAN 2 would generally be preferred for VoIP traffic due to its lower latency, lower jitter, and significantly lower loss percentage, despite its lower bandwidth compared to WAN 1. The high bandwidth of WAN 1 may be more suitable for other types of traffic that are less sensitive to latency and jitter, such as bulk data transfers.

Device Monitoring:
the device that is experiencing connectivity issues is the APP Server or Router 1, which has a status of Down. This means that the server is not responding to network requests or sending any dat a. You may want to check the physical connection, power supply, and configuration of the APP Server to troubleshoot the problem.


質問 # 428
A network engineer is setting up a new VoIP network for a customer. The current network is segmented only for computers and servers. No additional switch ports can be used in the new network. Which of the following does the engineer need to do to configure the network correctly? (Select TWO).
  • A. Change network translation definitions
  • B. Place devices in the perimeter network
  • C. Set up voice VLANs
  • D. Reconfigure the DNS
  • E. Implement a routing protocol
  • F. Enable 802.1Q
正解：C、F
解説：
To support VoIP on the same physical ports used by computers:
B:Enable 802.1Q: This standard supports VLAN tagging, allowing voice and data traffic to share the same port using separate VLANs.
D: Set up voice VLANs: Separating voice traffic into its own VLAN improves QoS and manageability.
Other options are not directly related to configuring VoIP over existing ports:
A: Network translation definitions (NAT) are unrelated to switch-level VLAN configuration.
C: Routing protocols are not necessary at the switch level for VLAN setup.
E: DNS is not required for the switch or VLAN setup.
F: Perimeter network (DMZ) is used for public-facing servers, not VoIP VLANs.
# Reference:
CompTIA Network+ N10-009 Official Objectives: 2.3 - Given a scenario, configure and verify VLANs.
CompTIA Network+ N10-009 Official Objectives: 3.6 - Explain the characteristics of network topologies and types.

質問 # 429
Which of the following steps of the troubleshooting methodology would most likely include checking through each level of the OSI model after the problem has been identified?
  • A. Implement the solution.
  • B. Establish a theory.
  • C. Create a plan of action.
  • D. Verify functionality.
正解：B
解説：
The CompTIA troubleshooting methodology includes steps like identifying the problem, establishing a theory of probable cause, testing the theory, creating a plan of action, implementing the solution, verifying functionality, and documenting findings. Establishing a theory involves analyzing the problem and considering possible causes, often by systematically checking each level of the OSI model (Physical, Data Link, Network, etc.) to pinpoint the root cause.
Why not Implement the solution? This step involves applying the fix, not analyzing the OSI model.
Why not Create a plan of action? This step focuses on planning the solution, not diagnosing the cause.
Why not Verify functionality? This step confirms the solution worked, not analyzing the OSI model.
Reference:CompTIA Network+ N10-009 Objective 5.2: Explain the troubleshooting methodology. The CompTIA Network+ Study Guide (e.g., Chapter 13: Network Troubleshooting) details the troubleshooting steps, noting that establishing a theory often involves using the OSI model to systematically identify the cause of network issues.
