A network engineer needs to enable device monitoring using authentication and encryption. Which of the following protocols offers this option?

Correct Answer:B
SNMPv3 is a protocol that offers device monitoring using authentication and encryption. SNMP stands for Simple Network Management Protocol, and it is a standard way of collecting and organizing information about network devices, such as routers, switches, servers, printers, and so on. SNMPv3 is the latest version of SNMP, and it provides enhanced security features, such as data integrity, data origin authentication, data confidentiality, and access control. SNMPv3 can use different algorithms to encrypt and authenticate the communication between the network management system and the
network devices12. References:

A technician is deploying a new switch model and would like to add it to the existing network monitoring software. The technician wants to know what metrics can be gathered from a given switch. Which of the following should the technician utilize for the switch?

Correct Answer:A
To determine what metrics can be gathered from a given switch, a technician should utilize the Management Information Base (MIB). The MIB is a database of network management information that is used to manage and monitor network devices. It contains information about device configuration, status, and performance.

An administrator is investigating reports of network slowness in a building. While looking at the uplink interface statistics In the switch's CLI, the administrator discovers the uplink Is at 100% utilization However, the administrator is unsure how to Identify what traffic is causing the saturation. Which of the following tools should the administrator utilize to identify the source and destination addresses of the traffic?

Correct Answer:D
To identify the source and destination addresses of the traffic causing network saturation, the network administrator should use a network protocol analyzer that supports the NetFlow protocol. NetFlow is a network protocol that collects IP traffic information as it enters or exits an interface and sends it to a NetFlow collector for analysis. This data includes the source and destination addresses of the traffic, the ports used, and the number of bytes and packets transferred.
Therefore, the correct answer is option D, NetFlow.

A company receives a cease-and-desist order from its ISP regarding prohibited torrent activity. Which of the following should be implemented to comply with the cease-and-desist order?

Correct Answer:B
Content filtering is a technique that blocks or allows access to certain types of web content, based on predefined criteria or policies. Content filtering can be used to comply with the cease-and-desist order by preventing users from accessing torrent sites or downloading torrent files, which are often used for illegal file sharing or piracy. Content filtering can also protect the network from malware, phishing, or inappropriate content.

A store owner would like to have secure wireless access available for both business
equipment and patron use. Which of the following features should be configured to allow different wireless access through the same equipment?

Correct Answer:D
SSID (Service Set Identifier) is a feature that should be configured to allow different wireless access through the same equipment. SSID is the name of a wireless network that identifies it from other networks in the same area. A wireless access point (AP) can support multiple SSIDs with different security settings and network policies. For example, a store owner can create one SSID for business equipment and another SSID for patron use, and assign different passwords, VLANs, and QoS levels for each SSID.
