- A. On-path attack
- B. Evil twin
- C. IP spoofing
- D. VLAN hopping
正解：D
解説：
Explanation
The attack which, if successful, would provide a malicious user who is connected to an isolated guest network access to the corporate network is VLAN hopping. VLAN hopping is an attack technique which involves tricking a switch into sending traffic from one VLAN to another. This is done by sending specially crafted packets, which force the switch to send traffic from one VLAN to another, thus allowing the malicious user to gain access to the corporate network.

A technician thinks one of the router ports is flapping. Which of the following available resources should the technician use in order to determine if the router is flapping?
- A. Audit logs
- B. Syslog
- C. Traffic logs
- D. NetFlow
正解：B
解説：
Explanation
Syslog is a protocol that allows network devices to send event messages to a centralized server or console for logging and analysis1. Syslog can help a technician to determine if a router port is flapping by providing timestamps, severity levels, and descriptions of the events that occur on the router, such as interface up or down, link state change, or error messages. Syslog can also help to identify the cause and frequency of the port flapping and troubleshoot the issue.
Audit logs are records of actions or events that occur on a system or network, such as user login, file access, configuration change, or policy violation. Audit logs can help to monitor and verify the activities and behaviors of users, devices, or applications on a system or network. Audit logs can also help to detect and investigate security incidents, compliance issues, or performance problems. However, audit logs do not provide detailed information about router port flapping.
NetFlow is a protocol that collects and analyzes network traffic data for monitoring and troubleshooting purposes2. NetFlow can help to identify the sources, destinations, volumes, and types of traffic on a network.
NetFlow can also help to optimize network performance, security, and capacity planning. However, NetFlow does not provide detailed information about router port flapping.
Traffic logs are records of network traffic that pass through a device or application, such as a firewall, proxy, or web server. Traffic logs can help to monitor and filter the network traffic based on rules or policies. Traffic logs can also help to detect and prevent malicious traffic, such as malware, attacks, or unauthorized access.
However, traffic logs do not provide detailed information about router port flapping.

A network administrator is concerned about a rainbow table being used to help access network resources.
Which of the following must be addressed to reduce the likelihood of a rainbow table being effective?
- A. Data loss prevention policy
- B. Acceptable use policy
- C. Password policy
- D. Remote access policy
正解：C
解説：
Explanation
A password policy must be addressed to reduce the likelihood of a rainbow table being effective. A rainbow table is a precomputed table of hashed passwords and their corresponding plaintext values. A rainbow table can be used to crack hashed passwords by performing a reverse lookup of the hash value in the table. A password policy is a set of rules and guidelines that define how passwords should be created, used, and managed in an organization. A password policy can help prevent rainbow table attacks by enforcing strong password requirements, such as length, complexity, expiration, and history. A strong password is one that is hard to guess or crack by using common methods such as brute force or dictionary attacks. References:

質問 # 111
A network technician is investigating a trouble ticket for a user who does not have network connectivity. All patch cables between the wall jacks and computers in the building were upgraded over the weekend from Cat
5 to Cat 6. The newly installed cable is crimped With a TIA/EIA 568A on one end and a TIA/EIA 568B on the other end. Which of the following should the technician do to most likely fix the issue?
- A. Ensure the switchport has POE enabled.
- B. Ensure the switchport has STP enabled.
- C. Crimp the cable as a rollover cable.
- D. Crimp the cable as a straight-through cable.
正解：D
解説：
Explanation
Crimping the cable as a straight-through cable is the most likely fix for the issue where users are unable to access any network resources after upgrading from Cat 5 to Cat 6 cables. Crimping is a process of attaching connectors to the ends of cables using a tool called a crimper. A straight-through cable is a type of twisted-pair cable that has the same wiring scheme on both ends, meaning that each pin on one end is connected to the same pin on the other end. A straight-through cable is used to connect devices that operate on different layers of the OSI model, such as a computer and a switch, or a switch and a router. If the newly installed cable is crimped with TIA/EIA 568A on one end and TIA/EIA 568B on the other end, it becomes a crossover cable. A crossover cable is a type of twisted-pair cable that has opposite wiring schemes on both ends, meaning that each pin on one end is connected to a different pin on the other end. A crossover cable is used to connect devices that operate on the same layer of the OSI model, such as two computers or two switches. Using a crossover cable instead of a straight-through cable can cause network communication errors or failures.
