CompTIA Updated N10-008 Exam Questions and Answers by willow-rose

 Link aggregation is a technique that allows multiple network interfaces to act as a single logical interface, increasing the bandwidth and redundancy of the network connection. Link aggregation can improve the performance of the network by balancing the traffic load across multiple links and providing failover in case one link fails. Link aggregation is also known as port trunking, port channeling, or NIC teaming.

The management plane is responsible for managing and controlling network devices. Let’s evaluate the options:

• Routing table: Part of the control plane, used for making forwarding decisions.
• Current configuration: Part of the management plane. It includes settings, access control lists, and other configuration details.
• File operations: Typically part of the management plane. It involves tasks like uploading/downloading configurations, firmware updates, and backups.
• Console port: Also part of the management plane. It provides direct access to the device for configuration and troubleshooting.

Among the options, the one most closely associated with the management plane is the current configuration.

Port 25 is the port number that is commonly used for Simple Mail Transfer Protocol (SMTP), which is a protocol that allows sending and receiving email messages over a network1. Port 25 from the copier’s IP address should be allowed so that scanned documents can be emailed to recipients.

Port 22 is the port number that is commonly used for Secure Shell (SSH), which is a protocol that allows secure and encrypted remote access and control of a device over a network1. Port 22 from the copier’s IP address is not necessary for emailing scanned documents.

Port 53 is the port number that is commonly used for Domain Name System (DNS), which is a protocol that allows resolving domain names to IP addresses and vice versa on a network1. Port 53 from the copier’s IP address is not necessary for emailing scanned documents.

Port 80 is the port number that is commonly used for Hypertext Transfer Protocol (HTTP), which is a protocol that allows transferring web pages and other resources over a network1. Port 80 from the copier’s IP address is not necessary for emailing scanned documents.

itter is the variation in latency or delay of packets in a network. Satellite WAN links have high latency and are prone to jitter, which can affect the quality of voice and video applications. Jitter is the greatest concern for this type of connection
