Which Category to Protocol mapping for NBAR is correct?
Click on the arrows to vote for the correct answer
A. B. C. D.Answer:
NBAR (Network-Based Application Recognition) is a feature in Cisco routers and switches that enables application-level classification of network traffic, based on the characteristics of the application data flowing over the network.
The correct Category to Protocol mapping for NBAR depends on the specific requirements of the network and the applications being used. However, in the given options, we can analyze the mappings as follows:
A. Category: Enterprise Applications Protocol: Citrix ICA, PCAnywhere, SAP, IMAP
This mapping is appropriate for identifying traffic related to enterprise applications, such as Citrix ICA, PCAnywhere, SAP, and IMAP. These applications are typically used for remote access and file sharing purposes. However, this mapping does not cover other categories of traffic, such as web traffic, email traffic, or network management traffic.
B. Category: Internet Protocol Protocol: FTP, HTTP, TFTP
This mapping is appropriate for identifying traffic related to Internet Protocol (IP) applications, such as FTP, HTTP, and TFTP. These applications are commonly used for file transfer and web browsing purposes. However, this mapping does not cover other categories of traffic, such as network management or enterprise applications traffic.
C. Category: Network Management Protocol Protocol: ICMP, SNMP, SSH, Telnet
This mapping is appropriate for identifying traffic related to network management protocols, such as ICMP, SNMP, SSH, and Telnet. These protocols are typically used for network monitoring and management purposes. However, this mapping does not cover other categories of traffic, such as enterprise applications or web traffic.
D. Category: Network Mail Services Protocol:
The fourth option is not completed and doesn't provide any protocols.
In summary, each mapping option covers a specific set of protocols and categories of traffic. Therefore, the correct Category to Protocol mapping for NBAR depends on the specific requirements of the network and the applications being used.
