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.Reference:1:JSON Introduction,2:JSON Syntax

Traffic is load-balancing over both links, causing packets to arrive out of order. This can cause voice quality issues, such as jitter and delay. To avoid this problem, voice traffic should be sent over a single path, using a routing protocol that supports unequal-cost load balancing, such as EIGRP. The source of this answer is the Cisco ENCOR v1.1 course, module 4, lesson 4.3: Implementing EIGRP.

This is because the remote span VLAN is used to transport the mirrored traffic from the source switch to the destination switch, where the monitoring server is connected. The remote span VLAN must be defined on both switches and must not be used for any other purpose. The source of this answer is the Cisco ENCOR v1.1 course, module 6, lesson 6.2: Implementing SPAN, RSPAN, and ERSPAN.

This is because the GCMP256 cipher is the only one that supports both WPA2 and WPA3 with the Personal security type. The GCMP256 cipher provides stronger encryption and authentication than the CCMP ciphers, which are only compatible with WPA2. The source of this answer is the Cisco ENCOR v1.1 course, module 7, lesson 7.2: Implementing WPA2 and WPA3.

This is because the EEM applet needs to specify the full path of the Tcl script that is stored in the flash memory of the device. The script name is write_backup.tcl and it is used to backup the running configuration to a remote server. The source of this answer is the Cisco ENCOR v1.1 course, module 8, lesson 8.3: Implementing Embedded Event Manager.

This is because the REST API response shows the details of a network device with the specified MAC address. The GET method is used to retrieve information from the Cisco DNA Center server. The network-device resource is used to access the network device inventory. The macAddress parameter is used to filter the results by the MAC address of the device. The source of this answer is the Cisco ENCOR v1.1 course, module 8, lesson 8.4: Implementing REST API.

This is because VXLAN is a network virtualization technology that encapsulates Layer 2 frames in UDP headers and allows them to be transported over Layer 3 networks. VXLAN is used in Cisco SD-Access to create virtual networks that span across multiple physical locations and devices. VXLAN performs the data plane forwarding function, which is responsible for moving packets from one point to another based on the destination address. The source of this answer is the Cisco ENCOR v1.1 course, module 9, lesson 9.2: Implementing VXLAN.
