   A network engineer is concerned about VLAN hopping happening on the network. Which of the following should the engineer do to address this concern?

   • AConfigure private VLANs.
   • BChange the default VLAN.
   • CImplement ACLs on the VLAN.
   • DEnable dynamic ARP inspection.

   Show answer

   Answer: B

   Explanation

   By changing the native VLAN, the attacker would not be able to deceive the switch by sending double tagging frame, because in that case the switch would drop the frame since its outer tag would have a VLAN ID (native VLAN ID) that is not the same as the access VLAN configured on the attacker port.

   A customer calls the help desk to report that users are unable to access any network resources. The issue started earlier in the day when an employee rearranged the wiring closet. A technician goes to the site but does not observe any obvious damage. The statistics output on the switch indicates high CPU usage, and all the lights on the switch are blinking rapidly in unison. Which of the following is the MOST likely explanation for these symptoms?

   • AThe switch was rebooted and set to run in safe mode.
   • BThe line between the switch and the upstream router was removed.
   • CA cable was looped and created a broadcast storm.
   • DA Cat 6 cable from the modem to the router was replaced with Cat 5e.

   Show answer

   Answer: C

   Explanation

   The symptoms, including high CPU usage and rapidly blinking switch lights, are most likely due to a cable loop in the network causing a broadcast storm, which is overwhelming network resources and disrupting connectivity.

   A user stores large graphic files. The time required to transfer the files to the server is excessive due to network congestion. The user's budget does not allow for the current switches to be replaced. Which of the following can be used to provide FASTER transfer times?

   • AHalf duplex
   • BJumbo frames
   • CLACP
   • D802.1Q

   Show answer

   Answer: B

   Explanation

   B. Jumbo frames Jumbo frames can be used to provide faster transfer times for large files in situations where network congestion is a concern. Jumbo frames allow for larger data payloads to be transmitted in a single frame, reducing the overhead associated with smaller frames and improving efficiency. Option B, Jumbo frames, would help in this scenario by reducing the number of frames required to transfer large graphic files, thus improving the overall transfer speed.

10. Question 530 · 871 in bank

    A sales team at a company uses a SaaS solution primarily for videoconferencing and a CRM application that connects to a database server in the corporate data center. Which of the following VPN solutions would allow secure, remote access for sales staff to the CRM application without impacting videoconferencing traffic?

    • AClientless
    • BSite-to-site
    • CSplit tunnel
    • DFull tunnel

    Show answer

    Answer: C

    Explanation

    The best VPN solution for the sales team would be a split tunneling VPN. This type of VPN allows you to route specific traffic through the VPN tunnel, while sending other traffic directly over the internet. In this case, the sales team would route the CRM traffic through the VPN tunnel to ensure that it is secure. However, they would not route the videoconferencing traffic through the VPN tunnel, as this could impact the performance of their video calls. Here are some of the benefits of using a split tunneling VPN: Security: Split tunneling VPNs can help to improve the security of your network by routing sensitive traffic through the VPN tunnel. Performance: Split tunneling VPNs can help to improve the performance of your network by sending non-sensitive traffic directly over the internet. Flexibility: Split tunneling VPNs give you more flexibility in how you route your traffic.
