CCNA: Cisco Certified Network Associate — Question 352

Which feature or protocol determines whether the QOS on the network is sufficient to support IP services?

Answer options

• A. LLDP
• B. CDP
• C. IP SLA
• D. EEM

Correct answer: C

Explanation

The correct answer is IP SLA, which actively measures the performance of the network and ensures that Quality of Service (QoS) parameters are met for IP services. LLDP and CDP are both protocols for network device discovery and advertisement, while EEM is used for event management, but none of them specifically assess QOS for IP services.
