105p2 Modules 9, 10, 11, & 12

(Module 9)

What is the term used to indicate a variation of delay?

• jitter

• serialization delay

• speed mismatch

• latency

A network engineer performs a ping test and receives a value that shows the time it takes for a packet to travel from a source to a destination device and return. Which term describes the value?

• latency
• jitter
• priority
• bandwidth

What role do network devices play in the IntServ QoS model?

• Network devices ensure that resources are available before traffic is allowed to be sent by a host through the network.
• Network devices are configured to service multiple classes of traffic and handle traffic as it may arrive
• <br />Network devices use QoS on a hop-by-hop basis to provide excellent scalability.
• Network devices provide a best-effort approach to forwarding traffic.

Which device would be classified as a trusted endpoint?

• router
• IP Phone
• firewall
• switch

Under which condition does congestion occur on a converged network with voice, video, and data traffic?

• if video traffic requests more bandwidth than voice traffic requests
• if the request for bandwidth exceeds the amount of bandwidth available
• if a user downloads a file that exceeds the file limitation that is set on the server
• if voice traffic latency begins to decrease across the network

Which type of traffic does Cisco recommend be placed in the strict priority queue (PQ) when low latency queuing (LLQ) is being used?

• video
• management
• voice
• data

Which model is the only QoS model with no mechanism to classify packets?

• hard QoS
• IntServ
• DiffServ
• best-effort

What are two characteristics of voice traffic? (Choose two.)

• it is bursty.
• it consumes few network resources
• it can tolerate latency up to 400ms
• it is insensitive to packet loss
• it is delay sensitive

(Module 10)

What are two reasons for an administrator to issue the copy running-config tftp command on a switch or router? (Choose two.)

• to have a backup of the running configuration file in the router​

• to save the running configuration file to a remote location

• to transfer the current configuration file to a server

• to force an automatic reload of the device

• to overwrite the current configuration

What information can be gathered about a neighbor device from the show cdp neighbors detail command that cannot be found with the show cdp neighbors command?

• the platform that is used by the neighbor
• the hostname of the neighbor
• the IP address of the neighbor
• the capabilities of the neighbor
