CompTIA Updated N10-008 Exam Questions and Answers by isa

• Management information bases (MIBs) are hierarchical databases of network objects that are defined using a subset of ASN.1 called SMIv212.
• MIBs describe the properties and capabilities of network devices that can be monitored and managed using SNMP12.
• MIBs are organized into modules that correspond to different standards, vendors, or applications12.
• MIBs are accessed by SNMP managers and agents using object identifiers (OIDs) that uniquely identify each network object12.
• MIBs are updated periodically to reflect changes in network technologies, protocols, or device features12.
• Updating the MIBs on the SNMP manager and agent is necessary to ensure compatibility and interoperability between different versions of network devices and operating systems12.
• Updating the MIBs can also enable new monitoring and management functions that are supported by the newer versions of network devices and operating systems12.
• B. System baseline is not a correct answer because a system baseline is a set of performance metrics that are obtained by measuring the network for a specific time period34.
• A system baseline is used to validate the current network status, identify trends, and plan for future changes34.
• A system baseline is not related to adding a new system to monitoring, as it does not define the network objects or the SNMP protocol34.
• C. Network device logs are not a correct answer because network device logs are records of events or activities that occur on network devices56.
• Network device logs are used to troubleshoot, audit, or analyze network performance and security issues56.
• Network device logs are not related to adding a new system to monitoring, as they do not define the network objects or the SNMP protocol56.
• D. SNMP traps are not a correct answer because SNMP traps are unsolicited messages that are sent by SNMP agents to SNMP managers when a significant event occurs on a network device78.
• SNMP traps are used to notify the network manager of urgent or abnormal situations that require attention78.
• SNMP traps are not related to adding a new system to monitoring, as they do not define the network objects or the SNMP protocol78.

An AAAA record is a type of DNS record that maps a domain name to an IPv6 address. It is similar to an A record, which maps a domain name to an IPv4 address, but it uses a 128-bit address instead of a 32-bit one. An AAAA record allows a domain name to be resolved by both IPv4 and IPv6 clients, and it is necessary for accessing websites and services that use IPv6.

 A split tunnel VPN solution would allow secure, remote access for sales staff to the CRM application without impacting videoconferencing traffic. A VPN stands for virtual private network, which is a secure connection between two or more devices over a public network, such as the internet. A VPN encrypts and authenticates the data, ensuring its confidentiality and integrity. A split tunnel VPN is a type of VPN that allows some traffic to go through the VPN tunnel, while other traffic goes directly to the internet. This can improve performance and bandwidth utilization by reducing unnecessary encryption and routing overhead. By using a split tunnel VPN, sales staff can access the CRM application that connects to a database server in the corporate data center through the VPN tunnel, while using online videoconferencing services through their local internet connection. References: [CompTIA Network+ Certification Exam Objectives], What Is Split Tunneling? | NordVPN

When a DHCP client is connected to a network and no DHCP server is available, the client can automatically configure a link-local address in the 169.254.0.0/16 range using the Automatic Private IP Addressing (APIPA) feature. So, the correct answer is option B, 169.254.1.128. This is also known as an APIPA address.
