CompTIA Network+ Certification Exam 認定 N10-009 試験問題 (Q356-Q361):質問 # 356
Which of the following is used to estimate the average life span of a device?
  • A. RTO
  • B. RPO
  • C. MTTR
  • D. MTBF
正解：D
解説：
Understanding MTBF:
Mean Time Between Failures (MTBF): A reliability metric that estimates the average time between successive failures of a device or system.
Calculation and Importance:
Calculation: MTBF is calculated as the total operational time divided by the number of failures during that period.
Usage: Used by manufacturers and engineers to predict the lifespan and reliability of a device, helping in maintenance planning and lifecycle management.
Comparison with Other Metrics:
RTO (Recovery Time Objective): The maximum acceptable time to restore a system after a failure.
RPO (Recovery Point Objective): The maximum acceptable amount of data loss measured in time.
MTTR (Mean Time to Repair): The average time required to repair a device or system and return it to operational status.
Application:
MTBF is crucial for planning maintenance schedules, spare parts inventory, and improving the overall reliability of systems.
Reference:
CompTIA Network+ study materials on reliability and maintenance metrics.

質問 # 357
A network technician needs to install patch cords from the UTP patch panel to the access switch for a newly occupied set of offices. The patch panel is not labeled for easy jack identification.
Which of the following tools provides the easiest way to identify the appropriate patch panel port?
  • A. Toner
  • B. Visual fault locator
  • C. Laptop
  • D. Cable tester
正解：A
解説：
A toner probe, often referred to as a toner and probe kit, is the easiest and most effective tool for identifying individual cables in a bundle, especially in situations where the patch panel is not labeled. The toner sends an audible tone through the cable, and the probe detects the tone at the other end, allowing the technician to quickly identify the correct cable.
Functionality: The toner generates a tone that travels along the cable. When the probe is placed near the correct cable, it detects the tone and emits a sound.
Ease of Use: Toner probes are straightforward to use, even in environments with many cables, making them ideal for identifying cables in unlabeled patch panels.
Efficiency: This method is much faster and more reliable than manual tracing, especially in complex setups.

質問 # 358
As part of an attack, a threat actor purposefully overflows the content-addressable memory (CAM) table on a switch. Which of the following types of attacks is this scenario an example of?
  • A. Evil twin
  • B. MAC flooding
  • C. ARP spoofing
  • D. DNS poisoning
正解：B
解説：
* Definition of MAC Flooding:
* MAC flooding is an attack where a malicious actor sends numerous fake MAC addresses to a switch, overwhelming its CAM table. The CAM table stores MAC addresses and their associated ports for efficient traffic forwarding.
* Impact of MAC Flooding:
* CAM Table Overflow:When the CAM table is full, the switch cannot learn new MAC addresses and is forced to broadcast traffic to all ports, leading to a degraded network performance and potential data interception.
* Switch Behavior:The switch operates in a fail-open mode, treating the network as a hub, which can be exploited for eavesdropping on traffic.
* Comparison with Other Attacks:
* ARP Spoofing:Involves sending false ARP (Address Resolution Protocol) messages to associate the attacker's MAC address with the IP address of another device.
* Evil Twin:Involves creating a rogue wireless access point that mimics a legitimate one to intercept data.
* DNS Poisoning:Involves corrupting the DNS cache with false information to redirect traffic to malicious sites.
* Preventive Measures:
* Port Security:Configure port security on switches to limit the number of MAC addresses per port, preventing CAM table overflow.
* Network Segmentation:Use VLANs to segment network traffic and limit the impact of such attacks.

* CompTIA Network+ study materials on network security threats and mitigation techniques.

質問 # 359
To reduce costs and increase mobility, a Chief Technology Officer (CTO) wants to adopt cloud services for the organization and its affiliates. To reduce the impact for users, the CTO wants key services to run from the on-site data center and enterprise services to run in the cloud. Which of the following deployment models is the best choice for the organization?
  • A. Hybrid
  • B. Public
  • C. Private
  • D. SaaS
正解：A
解説：
A hybrid cloud deployment model is the best choice for the CTO's requirements. It allows the organization to run key services from the on-site data center while leveraging the cloud for enterprise services. This approach provides flexibility, scalability, and cost savings, while also minimizing disruptions to users by keeping critical services local. The hybrid model integrates both private and public cloud environments, offering the benefits of both.

質問 # 360
A network engineer is implementing a new connection between core switches. The engineer deploys the following configurations:
Core-SW01
vlan 100
name
interface Ethernet 1/1
channel-group 1 mode active
interface Ethernet 1/2
channel-group 1 mode active
interface port-channel 1
switchport mode trunk
switchport trunk allow vlan 100
Core-SW02
vlan 100
name
interface Ethernet 1/1
switchport mode trunk
switchport trunk allow vlan 100
interface Ethernet 1/2
switchport mode trunk
switchport trunk allow vlan 100
interface port-channel 1
switchport mode trunk
switchport trunk allow vlan 100
Which of the following is the state of the Core-SW01 port-channel interfaces?
  • A. Error disabled
  • B. Suspended
  • C. Administratively down
  • D. Incrementing CRC errors
正解：B
解説：
On Core-SW01, the ports are configured with LACP (mode active) for link aggregation. On Core-SW02, the ports are configured as independent trunks, not as part of an LACP group. Because of this mismatch, LACP cannot form the bundle, and the aggregated ports on SW01 will go into a suspended state.
A). CRC errors suggest cabling or signal integrity issues, not config mismatch.
B). Error disabled occurs when a violation (like BPDU guard or port security) disables the port, not LACP mismatch.
C). Administratively down indicates a shutdown command, not the case here.
