   Which Python data structure does my_json contain?

   • Amap
   • Blist
   • Cjson
   • Ddict

   Show answer

   Answer: D

   Explanation

   The right answer is D. Dictionaries are analogous to "hashes" in some other languages. A dictionary is a data structure that stores simple key-value pairs. They make it very easy and fast to store and retrieve a value by supplying a key to be used as an index for that value. Values: The values in a Python dictionary can be anything, and like lists the types don't have to be consistent. Keys: A dictionary's keys have an important restriction: Whatever you want to use as a key has to be immutable and hash-able. This means that you could use a tuple as a key (immutable), but not a list (mutable). Also note that all of the basic data types that you learned about previously (int, float, bool, str, bytes ) are immutable and can be used as dictionary keys. You create a dictionary by using curly braces {] , separating a key from its value with a colon : , and separating the key-value pairs with commas. You can access and update elements using indexing; however, instead of using numerical sequential index numbers, you use the key as the index. You can add new elements simply by assigning a value to a new key.

10. Question 20 · 530 in bank

    A company has written a script that creates a log bundle from the Cisco DNA Center every day. The script runs without error and the log bundles are produced. However, when the script is run during business hours, people report poor voice quality of phone calls. What explains this behavior?

    • AThe script is written in a low-level programming language where there is no memory safety. This causes a buffer overflow and disruption on the network.
    • BThe speed and duplex settings in Cisco DNA Center are set incorrectly, which causes the transfer to be too slow.
    • CThe script is running in the Voice VLAN and causes delays and jitter in the subnet.
    • DGenerating the logs causes the CPU on the network controller to spike, which causes delays in forwarding the voice IP packets.

    Show answer

    Answer: C

    Explanation

    If speed and duplex settings are incorrect, the problem should appears all the time. During office hours, users are using the IP phones, if the application is running on the voice LAN accidentally, it will impact the quality of the voice
