Which of the following would be violated if an employee accidentally deleted a customer's data?
Answer(s): A
The integrity of data ensures that the information remains accurate, complete, and unaltered unless explicitly modified by authorized personnel. If an employee accidentally deletes customer data, the data's integrity is violated because the original data is no longer accurate or complete. This type of incident directly impacts the trustworthiness of the data within the system.
A network engineer is now in charge of all SNMP management in the organization. The engineer must use a SNMP version that does not utilize plaintext data.Which of the following is the minimum version of SNMP that supports this requirement?
Answer(s): D
SNMPv3 is the minimum version of SNMP that provides enhanced security features, including support for authentication and encryption. Unlike SNMPv1 and SNMPv2c, which transmit data (including community strings) in plaintext, SNMPv3 allows for the use of encrypted communication, ensuring data confidentiality and protection against interception. This makes it the suitable choice for environments requiring secure SNMP management.
A company recently acquired a number of sites and no documentation was provided. A network administrator needs to identify and document all of the digital assets in use.Which of the following is the best method for the administrator to use?
Network discovery is the best method for identifying and documenting all digital assets in use. It involves using tools and techniques to scan and identify devices, services, and resources connected to the network. These tools can detect IP addresses, open ports, operating systems, and other network details, helping the administrator to create an inventory of digital assets efficiently and accurately. Other options like physical inventory may miss devices or services not physically visible, and packet capture is more focused on analyzing traffic rather than discovering assets.
A network administrator recently upgraded a wireless infrastructure with new APs. Users are reporting that, when stationary, the wireless connection drops and reconnects after 20 to 30 seconds.While reviewing the logs, the administrator notices that the APs are changing channels.Which of the following is the most likely reason for the service interruptions?
The most likely reason for the service interruptions is channel interference. Wireless Access Points (APs) use a feature called Dynamic Frequency Selection (DFS) or automatic channel selection to switch to less congested channels when interference is detected. However, when the APs change channels, there is a brief service disruption for connected devices. This is often noticed when the devices are stationary, as they remain connected to the same AP, but the channel change interrupts the connection temporarily. Addressing channel interference, such as using non-overlapping channels and optimizing AP placement, can reduce these disruptions.
A network administrator needs to set up a multicast network for audio and video broadcasting.Which of the following networks would be the most appropriate for this application?
Answer(s): C
The IP address range 224.0.0.0 to 239.255.255.255 is reserved for multicast traffic. Multicast is used for applications such as audio and video broadcasting, where data is sent from one source to multiple recipients efficiently. The 224.0.0.0/24 range is specifically reserved for local network multicast (e.g., routing protocol updates). For broader multicast applications, addresses in the 224.0.1.0 to 239.255.255.255 range would be used. This makes the 224.0.0.0/24 network the most appropriate choice for setting up a multicast network.
A user connects to a corporate VPN via a web browser and is able to use TLS to access the internal financial system to input a time card.Which of the following best describes how the VPN is being used?
The term "clientless" VPN refers to a VPN connection that does not require the user to install specialized software or a VPN client. Instead, the user connects through a web browser, typically using SSL/TLS protocols (often referred to as SSL VPN). In this case, the user accesses the corporate VPN and is able to use TLS to access internal resources, which indicates a clientless VPN solution. Other options like client-to-site and full tunnel would require dedicated VPN client software, and site-to-site refers to VPN connections between two network locations, not individual users.
A network administrator needs to fail over services to an off-site environment. This process will take four weeks to become fully operational.Which of the following DR concepts does this describe?
Answer(s): B
A warm site is a disaster recovery (DR) concept where the off-site environment is partially configured and can be brought online within a relatively short time (typically a few days to a few weeks). In this scenario, the process will take four weeks to become fully operational, which aligns with the characteristics of a warm site. A hot site would be fully operational and ready to use immediately, while a cold site would require the longest recovery time, as it would need to be completely set up from scratch. An active-active approach involves running services in multiple locations simultaneously, which is not the case here.
A security analyst wants to control internet access based on site reputation and categorization. The analyst needs a solution that does not require traffic flow changes.Which of the following solutions would most likely meet these requirements?
DNS filtering allows for the control of internet access based on site reputation and categorization by filtering DNS requests. This approach does not require any changes to traffic flow, as it works by intercepting and blocking or allowing DNS requests based on predefined rules for site reputation and categorization. The user's requests to access websites are filtered at the DNS level before any traffic flows to the site.
