Cisco Finesse offers several capabilities:
* Browser Access: Agents can access Finesse directly from a browser, eliminating the need for any client-side installation or configuration. This simplifies deployment and maintenance.
* Gadget Containers: Finesse provides a single user interface that integrates multiple gadget containers, allowing for a seamless and unified experience.
Reference: Cisco DevNet Associate documentation on Cisco Finesse, which details its features and benefits, emphasizing ease of access and integration capabilities.
質問 # 161
How does a synchronous API request differ from an asynchronous API request?
- A. clients are able to access the results immediately
- B. clients subscribe to a webhook for operation results
- C. clients poll for the status of the execution of operations
- D. clients receive responses with a task id for further processing
正解：A
解説：
Synchronous API requests and asynchronous API requests differ primarily in how and when the client receives a response from the server.
* Synchronous API Request: In a synchronous API call, the client sends a request to the server and waits for a response. The client is blocked during this time, meaning it cannot perform other tasks until the server responds. The key characteristic is that the client is able to access the results immediately after the request is processed. This is suitable for operations that need an immediate response and where the processing time is relatively short.
* Asynchronous API Request: In an asynchronous API call, the client sends a request and continues its process without waiting for the server to respond. The server processes the request and sends the response back to the client at a later time. The client might receive a task ID (option A), subscribe to a webhook (option B), or poll for status (option D) to check when the operation is complete.

質問 # 164
Refer to the exhibit.
Which JSON snippet configures a new interface according to YANG model?
- A.
- B.
- C.
- D.
正解：B
解説：
To determine the correct JSON snippet for configuring a new interface according to the YANG model, we need to carefully examine both the YANG model definitions and the provided JSON snippets. Here's a step-by-step explanation:
* YANG Model Analysis:
* The ietf-interfaces YANG module defines a container interfaces with a list interface.
* Each interface has the following important leaves: name, enabled, and description.
* The ietf-ip YANG module augments the interface list with a container ipv4, which includes a list address. Each address has the ip and netmask leaves.
* Key Elements in JSON:
* To configure an interface, the JSON must include the name of the interface, its enabled status, and the IP address configuration.
* The structure should reflect the hierarchy defined by the YANG models.
* Options Analysis:
* Option A:
json
Copy code
"ietf-interfaces:interface": {
"name": "Loopback100",
"enabled": true,
"ietf-ip:ipv4": {
"address": [
{
"ip": "10.255.254.1",
"netmask": "255.255.255.0"
}
]
}
}
* This option correctly follows the hierarchy specified in the YANG model. The interface includes name and enabled leaves and augments with ietf-ip:ipv4 which includes the address list with ip and netmask.
* Option B:
"ietf-interfaces": {
"interface": {
"name": "Loopback100",
"enabled": true,
"ietf-ip": {
"ipv4": {
"address": [
{
"ip": "10.255.254.1",
"netmask": "255.255.255.0"
}
]
}
}
}
}
* This option incorrectly nests interface directly under ietf-interfaces, which does not match the YANG model's structure.
* Option C:
"interface": {
"name": "Loopback100",
"enabled": true,
"ipv4": {
"address": [
{
"ip": "10.255.254.1",
"netmask": "255.255.255.0"
}
]
}
}
* This option misses the namespace prefixes ietf-interfaces and ietf-ip required by the YANG model.
* Option D:
"ietf-interfaces:interface": {
"name": "Loopback100",
"enabled": true,
"ietf-ip:ipv4:address": [
{
"ip": "10.255.254.1",
"netmask": "255.255.255.0"
}
]
}
* This option incorrectly uses ietf-ip:ipv4:address directly, which does not align with the proper hierarchy where address should be nested inside ipv4.
Correct Explanation:
* Option A correctly adheres to the YANG model hierarchy and namespace specifications.
* It properly nests address within ipv4, which is itself nested within ietf-ip augmentation to interface.
* This structure is consistent with how the YANG models define the relationships between the elements.

質問 # 170
Which REST architectural constraint indicates that no client context should be stored on the server between requests?
- A. stateless
- B. uniform interface
- C. client-server
- D. cacheable
正解：A
解説：
RESTful constraints are described as follows:
- Client/server - clients and servers are fully separated and communicate only via the RESTful interface.
- Stateless - no client context or state is stored on the server between requests, and each client request must contain all of the information needed for the server to service the request.
- Cacheable - clients can cache responses, and servers must define the cacheability of the response.
- Layered - a client should not be able to tell whether it is connected to a server or to an intermediate that provides functionality such as security, caching, or load-balancing.
- Code on Demand (Optional) - servers can at times extend the capabilities of a client through the transfer of executable code or scripts.
- Uniform Interface - both client and server must adhere to a uniform interface that allows for the independent development of functionality.
- Resource Identification - individual resources are identified using URIs in requests.
Representations of resources are distinct from the actual resources and may be provided in formats such as HTML, XML, or JSON.

質問 # 172
Drag and drop the code from the bottom onto the box where the code is missing to construct a Python script that calls a REST API request. Not all options are used.
正解：
解説：
Explanation:
The Python script provided is designed to make a POST request to a REST API to create a new task in a to-do list application. Here's a step-by-step explanation of the script:
* Import the requests library to handle HTTP requests.
* Define the task dictionary with summary and description.
* Use the requests.post method to send a POST request to the specified URL, passing the task data as
* JSON and setting the appropriate Content-Type header.
* Check if the response status code is not 201 (which indicates successful creation). If it's not, raise an ApiError with the status code.
* Print the created task's ID from the JSON response.
The provided code options are:
* requests: the library used for making HTTP requests.
* status_code: used to check the HTTP response status.
* Content-Type: a header specifying the media type of the resource.
* raise: used to raise an exception if the status code is not as expected.
* return is not used in this context.

質問 # 175
What is the function of an Ethernet switch in a networking environment?
- A. to switch a frame from one port to another port based on IP address
- B. to switch a frame from one port to another port based on MAC address
- C. to block unwanted traffic
- D. to provide IP addressing to connected hosts
正解：B
解説：
An Ethernet switch operates at the Data Link layer (Layer 2) of the OSI model. Its primary function is to forward frames between devices based on their MAC (Media Access Control) addresses. When a frame arrives at the switch, the switch reads the destination MAC address and forwards the frame to the appropriate port that connects to the device with that MAC address.
* MAC Address Table: Switches maintain a MAC address table that maps each MAC address to a specific port. This table is built dynamically as the switch learns the MAC addresses of devices connected to its ports.
* Frame Switching: By using the MAC address table, the switch can efficiently switch frames only to the destination port, which reduces unnecessary traffic on other ports and improves network performance.
