  A. Cat5
  B. Cat 5e
  C. Cat 6
  D. Cat 7

• Question 1022:

  A network engineer is investigating reports of poor network performance. Upon reviewing a report, the engineer finds hundreds of CRC errors on an interface. Which of the following is the MOST likely cause of these errors?

  A. A bad wire on the Cat 5e cable
  B. The wrong VLAN assignment to the switchport
  C. A misconfigured QoS setting on the router
  D. Both sides of the switch trunk set to full duplex
  A. A bad wire on the Cat 5e cable

• Question 1023:

  A network administrator is investigating reports about network performance and finds high utilization on a switch uplink. The administrator is unsure whether this is an anomaly or normal behavior that will require an upgrade to resolve. Which of the following should the administrator reference to gain historical perspective?

  A. Device configuration review
  B. ARP table export
  C. Service-level agreement
  D. Network performance baseline
  D. Network performance baseline

  ---

  Explanation/Reference:

  A network performance baseline is a set of metrics that represents the normal or expected behavior of a network under various conditions and scenarios. A network performance baseline can help a network administrator to investigate reports about network performance by comparing the current metrics with the historical metrics and identifying any deviations or anomalies. A network performance baseline can also help to plan and justify network upgrades by showing the trends and patterns of network utilization and performance over time. A device configuration review is a process that involves checking and verifying the settings and parameters of a network device, such as a switch, router, firewall, or server. A device configuration review can help a network administrator to troubleshoot network issues by finding and fixing any errors, inconsistencies, or vulnerabilities in the device configuration. A device configuration review can also help to ensure compliance with security policies and best practices by applying the latest updates and patches to the device. An ARP table export is a file that contains the contents of the ARP (Address Resolution Protocol) table of a network device. The ARP table is a data structure that maps IP addresses to MAC addresses on a local network. An ARP table export can help a network administrator to monitor and manage the network devices on a local network by showing their IP addresses and MAC addresses. An ARP table export can also help to detect and prevent ARP spoofing attacks by identifying any duplicate or malicious entries in the ARP table. A service-level agreement (SLA) is a contract that defines the expectations and responsibilities of both parties in terms of service quality, availability, performance, and response time. An SLA can help a network administrator to provide and maintain a satisfactory level of service to the customers or users of the network by setting and measuring specific goals and metrics. An SLA can also help to resolve any disputes or issues that may arise between the service provider and the service consumer by establishing clear terms and conditions for the service delivery.

• Question 1024:

  Which of the following is the physical security mechanism that would MOST likely be used to enter a secure site?

  A. A landing page
  B. An access control vestibule
  C. A smart locker
  D. A firewall
  B. An access control vestibule

• Question 1025:

  Which of the following attacks, if successful, would provide a malicious user who is connected to an isolated guest network access to the corporate network?

  A. VLAN hopping
  B. On-path attack
  C. IP spoofing
  D. Evil twin
  A. VLAN hopping

  ---

  Explanation/Reference:

  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. 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. According to the CompTIA Network+ N10-008 Exam Guide VLAN hopping is a type of attack that is used to gain access to network resources that are not meant to be accessible by a user on a guest network.

• Question 1026:

  Which of the following VPN technologies should a network technician utilize to tunnel IPv6 traffic and multicast over an IPv4 WAN link?

  A. AH
  B. DTLS
  C. SSL
  D. GRE
  D. GRE

• Question 1027:

  Which of the following passwords would provide the best defense against a brute-force attack?

  A. ThisIsMyPasswordForWork
  B. Qwerty!@#$
  C. Password!1
  D. T5!8j5
  D. T5!8j5

• Question 1028:

  A technician is assisting a user who cannot access network resources when the workstation is connected to a VoIP phone. The technician identifies the phone as faulty and replaces it. According to troubleshooting methodology, which of the following should the technician do NEXT?

  A. Implement the solution.
  B. Test the theory.
  C. Duplicate the issue.
  D. Document the findings.
  E. Verify functionality.
  E. Verify functionality.

  ---

  Explanation/Reference:

  According to troubleshooting methodology, after identifying the faulty VoIP phone and replacing it, the technician should verify that the issue has been resolved by testing the workstation's access to network resources. This step is known as "Verifying Full System Functionality" or "Verifying the solution has been properly implemented" and it is the next step after implementing the solution.

  A. The wireless router is using an incorrect antenna type.
  B. The user's workstation does not support 802.11ax.
  C. The encryption protocol is mismatched.
  D. The network is experiencing interference.
  B. The user's workstation does not support 802.11ax.
