QUESTION 41
A network architect is considering whether to implement Cisco DNA Center to deploy devices on a new network. The organization is focused on reducing the time it currently takes to deploy devices in a traditional campus design. For which reason would Cisco DNA Center be more appropriate than traditional management options?

1. 
   Cisco DNA Center provides zero-touch provisioning to third-party devices.
   
2. 
   Cisco DNA Center supports deployment with a single pane of glass.
   
3. 
   Cisco DNA Center minimizes the level of syslog output when reporting on Cisco devices.
   
4. 
   Cisco DNA Center reduces the need for analytics on third-party access points and devices.
   

Correct Answer: B


QUESTION 42
How do TCP and UDP fit into a query-response model?

1. 
   TCP avoids using sequencing, and UDP avoids using acknowledgments.
   
2. 
   TCP uses error detection for packets, and UDP uses error recovery.
   
3. 
   TCP establishes a connection prior to sending data, and UDP sends immediately.
   
4. 
   TCP encourages out-of-order packet delivery, and UDP prevents re-ordering.
   

Correct Answer: C


QUESTION 43
Drag and drop the RF terms from the left onto the corresponding statements on the right.

A. -> measure of the minimum power required to decode a radio signal without excessive errors: receiver sensitivity

-> deviation from the propagation path that occurs when a signal encounters an obstacle: absorption
-> reduction of energy in a signal as it travels away from the access point and encounters free space or obstacles: reflection
-> measure of the total unwanted signals at the receiver: noise floor
-> relative power of the desired radio signal to unwanted signals at the receiver: signal-to-noise ratio
