The correct answer is A. DSCP 1 marked traffic will be re-marked to 63 and all other DSCP values will be honored.
The exhibit shows:
class-map match-any dscp-1
match ip dscp 1
policy-map set-dscp-63
class dscp-1
set dscp 63
interface GigabitEthernet0/0/0
mls qos trust dscp
service-policy input set-dscp-63
The class map matches packets with DSCP value 1:
match ip dscp 1
The policy map then changes the DSCP marking of those matched packets to 63:
set dscp 63
The policy is applied in the input direction on interface Gig0/0/0:
service-policy input set-dscp-63
Also, the interface is configured to trust DSCP:
mls qos trust dscp
That means incoming packets keep their DSCP markings unless a QoS policy explicitly changes them. Since the policy only matches DSCP 1, only that traffic is re-marked to 63. Traffic with other DSCP values is not matched by the policy and therefore remains trusted and unchanged.
* Traffic marked with DSCP 1 is matched by the class map.
* The policy re-marks that traffic to DSCP 63.
* All other DSCP-marked traffic is still trusted and therefore honored.
* B. DSCP 1 marked traffic will be ignored and DSCP 63 marked traffic will be honored. Incorrect, because DSCP 1 traffic is not ignored. It is specifically matched and re-marked.
* C. None. The service-policy configuration must be applied in the outbound direction. Incorrect, because QoS marking policies can be applied in the input direction, and this configuration is valid.
* D. DSCP 1 marked traffic will be re-marked to 63 and all other DSCP values will be ignored. Incorrect, because other DSCP values are not ignored. They are trusted due to mls qos trust dscp .
When you see:
* mls qos trust dscp # preserve incoming DSCP markings
* service-policy input with set dscp # re-mark only the traffic matched by the policy So here the result is:
DSCP 1 # changed to 63
All other DSCP values # trusted and left unchanged

The correct answer is A. json_final = json.loads(json_data).
When using Python on Cisco devices:
* The cli() function returns output as a string
* To work with structured data, the string must be converted into a JSON object (Python dictionary) The exhibit shows:
json_data = cli(cmd)
json_final = json.import(json_data)
This is incorrect because:
* json.import() is not a valid Python function
* The script fails to convert the JSON string into a Python object
json_final = json.loads(json_data)
* json.loads() parses a JSON-formatted string
* Converts it into a Python dictionary
* Enables access using keys like:
json_final[ " TABLE_intf " ][ " ROW_intf " ][0] [ " prefix " ]
* B. This line assumes the JSON is already converted into an object. It does not fix the conversion issue.
* C. Incorrect syntax and unnecessary; json is already imported properly.
* D. Just defines a command string; does not address JSON conversion.
Always remember the difference:
* json.loads() # String # Python object
* json.dumps() # Python object # String
Correct Automation Workflow:
* Run CLI command
* Capture output (string)
* Convert using json.loads()
* Parse using dictionary keys
This is a core concept for Cisco automation questions in the ENCOR exam.
