NEW QUESTION 6

How must network management traffic be treated when defining QoS policies?

• A. as delay-sensitive traffic in a low latency queue
• B. using minimal bandwidth guarantee
• C. using the same marking as IP routing
• D. as best effort

Answer: A

Explanation:
Low latency queuing (LLQ) adds a priority queue to CBWFQ from which delay-sensitive traffic, such as voice traffic, can be transmitted ahead of packets in other queues.
By configuring the quality of service (QoS), you can provide preferential treatment to specific types of traffic at the expense of other traffic types. Without QoS, the device offers best-effort service for each packet, regardless of the packet contents or size. The device sends the packets without any assurance of reliability, delay bounds, or throughput.
The following are specific features provided by QoS:
✑ Low latency
✑ Bandwidth guarantee
✑ Buffering capabilities and dropping disciplines
✑ Traffic policing
✑ Enables the changing of the attribute of the frame or packet header
✑ Relative services
✑ Modular QoS Command-Line Interface
✑ Supported QoS Features for Wired Access
✑ Hierarchical QoS

NEW QUESTION 16

Which JSON script is properly formatted?
A)

B)

C)

D)

• A. Option A
• B. Option B
• C. Option C
• D. Option D

Answer: A

Explanation:
Option A is the properly formatted JSON script. JSON (JavaScript Object Notation) is a standard text-based format for representing structured data based on JavaScript object syntax. It is commonly used for transmitting data in web applications (e.g., sending some data from the server to the client, so it can be displayed on a web page, or vice versa). The JSON syntax rules are as follows12:
✑ Data is in name/value pairs, separated by commas. A name/value pair consists of a field name (in double quotes), followed by a colon, followed by a value: "name": "value".
✑ Curly braces hold objects. An object can contain multiple name/value pairs: {"name": "value", "name": "value", ...}.
✑ Square brackets hold arrays. An array can contain multiple values, separated by commas: ["value", "value", ...].
✑ Values can be strings (in double quotes), numbers, booleans (true or false), null, objects, or arrays.
Option A follows these rules and is a valid JSON script. It defines an object with four name/value pairs: "name", "age", "hobbies", and "address". The value of "name" is a string, the value of "age" is a number, the value of "hobbies" is an array of strings, and the value of "address" is another object with two name/value pairs: "city" and "country". The object is enclosed in curly braces and the name/value pairs are separated by commas.
Option B is not a valid JSON script because it uses single quotes instead of double quotes for the field names and string values. JSON requires double quotes for strings12.
Option C is not a valid JSON script because it does not use commas to separate the name/value pairs. JSON requires commas to separate the data elements within an object or an array12.
Option D is not a valid JSON script because it uses a semicolon instead of a colon to separate the field name and the value. JSON requires a colon to separate the name and the value in a name/value pair12. References: 1: JSON Introduction, 2: JSON Syntax
