Which statement is true about CDP on a Cisco device? The show cdp neighbor detail command will reveal the IP address of a neighbor only if there is Layer 3 connectivity. To disable CDP globally, the no cdp enable command in interface configuration mode must be used. CDP can be disabled globally or on a specific interface. Because it runs at the data link layer, the CDP protocol can only be implemented in switches.

Which two statements describe how to assess traffic flow patterns and network traffic types using a protocol analyzer? (Choose two.) Capture traffic on the weekends when most employees are off work. Only capture traffic in the areas of the network that receive most of the traffic such as the data center.

Only capture WAN traffic because traffic to the web is responsible for the largest amount of traffic on a network.

Refer to the exhibit. Baseline documentation for a small company had ping round trip time statistics of 36/97/132 between hosts H1 and H3. Today the network administrator checked connectivity by pinging between hosts H1 and H3 that resulted in a round trip time of 1458/2390/6066. What does this indicate to the network administrator? Cisco ITN CCNA 1 v6.0 Chapter 11 Exam Beta Answer R&S 2018 2019 001 Connectivity between H1 and H3 is fine. H3 is not connected properly to the network. Something is causing interference between H1 and R1. Performance between the networks is within expected parameters. Something is causing a time delay between the networks.
Something is causing a time delay between the networks.
