    QUESTION NO: 343 Which of the following is a secure method for file transfer to a network device?

    • SNMPv2

    • TFTP

    • SCP

    • FTP

    Correct Answer
    A. SCP
    Explanation
    SCP (Secure Copy Protocol) is a secure method for file transfer to a network device. It uses SSH (Secure Shell) protocol to provide secure and encrypted file transfers. SCP ensures the confidentiality and integrity of the transferred files by encrypting the data and using authentication mechanisms. Unlike FTP (File Transfer Protocol) and TFTP (Trivial File Transfer Protocol), which do not provide secure file transfers, SCP is a recommended method for transferring files securely over a network. SNMPv2 (Simple Network Management Protocol version 2) is not a file transfer protocol, but rather a network management protocol.

    QUESTION NO: 351 The data center power will not be restored for several hours. Which of the following can be implemented in the future to allow the data center to keep running?

    • Connect all the switches to a batter backup

    • Connect all the switches to a generator.

    • Connect the data centers power to a generator.

    • Connect the data centers power to a UPS.

    Correct Answer
    A. Connect the data centers power to a generator.
    Explanation
    Connecting the data center's power to a generator would be the most effective solution in this situation. A generator can provide a continuous power supply for several hours, allowing the data center to keep running even when the main power source is unavailable. Using a battery backup or a UPS (Uninterruptible Power Supply) would only provide temporary power for a limited period of time, whereas a generator can provide a longer-term solution. Connecting all the switches to a generator would ensure that all the equipment in the data center remains powered and operational during the power outage.

    QUESTION NO: 329 Which of the following network security devices prevents users from propagating viruses?

    • IPS

    • Firewall

    • IDS

    • Content engine

    Correct Answer
    A. IPS
    Explanation
    An Intrusion Prevention System (IPS) is a network security device that monitors network traffic for malicious activities and prevents users from propagating viruses. It works by analyzing network packets and comparing them against a database of known attack signatures. When a potential threat is detected, the IPS can take immediate action to block the malicious traffic and prevent it from spreading throughout the network. This proactive approach helps to protect the network from viruses and other malware, ensuring a safer and more secure environment for users.

    QUESTION NO: 318 An administrator is using a packet analyzer across a single switch but is only receiving partial packet information. Which of the following would need to be implemented on the switch for the administrator?

    • Port authentication

    • Port mirroring

    • Spanning tree

    • VLAN

    Correct Answer
    A. Port mirroring
    Explanation
    Port mirroring would need to be implemented on the switch in order for the administrator to receive complete packet information. Port mirroring allows for the duplication of network traffic from one port to another, which would enable the packet analyzer to capture all packets passing through the switch. This feature is commonly used for network monitoring and troubleshooting purposes.

    QUESTION NO: 316 A network technician is installing a series of three access points to cover the entire wing of a building. Only one access point has a wired connection. 802.11g is being used for the wireless transmission. Which of the following channels should be used for the access points?

    • Channels 1-3-5

    • Channels 6-6-6

    • Channels 7-11-1

    • Channels 5-5-5

    Correct Answer
    A. Channels 6-6-6
    Explanation
    The correct answer is Channels 6-6-6. In the 802.11g standard, there are 11 channels available for use. However, these channels overlap with each other, causing interference. To minimize interference, it is recommended to use non-overlapping channels. Channels 1, 6, and 11 are the only non-overlapping channels in the 802.11g standard. Therefore, in this scenario, the access points should be set to Channels 6-6-6 to avoid interference and provide optimal coverage.
