NEW QUESTION # 94
A customer's cloud services must:
Migrate services to another data center on demand.
Save the operational state of the machine on demand.
Support Windows and Linux GUIs.
Maximize hardware utilization.
Which type of deployment meets these requirements?
- A. virtual machine
- B. container
- C. bare metal
- D. Kubernetes
Answer: A
Explanation:
Virtual machines (VMs) provide the flexibility and capabilities required to meet the described requirements.
VMs can easily migrate between data centers, save and restore their state, and support various operating systems and GUIs.
* Migration: VMs can be moved from one physical server or data center to another, providing high flexibility in resource management.
* State Saving: VMs support saving the operational state (snapshots), allowing quick recovery or migration.
* Support for GUIs: VMs can run different operating systems, including those with graphical user interfaces (GUIs) like Windows and Linux.
* Hardware Utilization: VMs enable better utilization of hardware resources by running multiple VMs on a single physical host.

NEW QUESTION # 103
Refer to the exhibit.
An API call is constructed to retrieve the inventory in XML format by using the API. The response to the call is 401 Unauthorized. Which two headers must be added to the API call? (Choose two.)
- A. Option C
- B. Option D
- C. Option A
- D. Option E
- E. Option B
Answer: A,D
Explanation:
The 401 Unauthorized response indicates that the API call lacks proper authentication. To authenticate a request using a Bearer token, the correct headers must be included. The "Authorization: Bearer <token>" header is the correct format for including a Bearer token in an API request. Additionally, specifying the correct content type can also be important, but in this case, the critical headers are related to authorization.
Reference:
Cisco DevNet Associate Study Guide: API Authentication (Chapter 7, Section: Authentication Methods for REST APIs).
NEW QUESTION # 104
Refer to the exhibit. A developer creates a script to obtain a list of devices by using the Cisco DNA Center API. The remote server authorizes the request only if an authentication token is supplied in the headers. A function named get_auth_token() must retrieve a valid token by using HTTP Basic Authentication. Which code must be added to complete the get_auth_token() function?
- A. resp = requests.post(url, auth=HTTPBasicAuth(DNAC_USER, DNAC_PASSWORD)) token = resp.json()['Token'] return token
- B. resp = http.post(url, auth=HTTPBasicAuth(DNAC_USER, DNAC_PASSWORD)) token = resp.json()['Token'] return token
- C. resp = http.post(url, auth=(DNAC_USER, DNAC_PASSWORD)) token = resp.json()['Token'] return token
- D. resp = requests.post(url, auth=(DNAC_USER, DNAC_PASSWORD)) token = resp.json ()['Token'] return token

NEW QUESTION # 106
Which type of OWASP threat forges a malicious HTTP request into an application?
- A. SQL Injection
- B. CSRF
- C. Clickjacking
- D. XSS
Answer: B
Explanation:
Cross-Site Request Forgery (CSRF) is a type of attack that forges a malicious HTTP request and sends it from a user's browser to a different site where the user is authenticated. The attacker tricks the user into executing unwanted actions on a web application in which the user is currently authenticated. This can lead to unauthorized actions being performed on the user's behalf.

NEW QUESTION # 109
A company deploys an application via containers in its local data center. As soon as the application goes into production, it starts to crash at specific hours of the day. After investigation, it is concluded that the crashes are due to too many users accessing the application simultaneously. The spikes must be addressed and allow for future growth without discarding the investment already made. Which deployment model must be used?
- A. hybrid cloud
- B. private cloud
- C. public cloud
- D. edge
Answer: A
Explanation:
A hybrid configuration is excellent for keeping latency or security-sensitive applications close to home while accessing cloud-based resources as an extension of your infrastructure. A hybrid model also allows for the rapid deployment and deprecating of temporary equipment, eliminating the need to over-provision purchases to support business peaks.
NEW QUESTION # 110 
Refer to the exhibit. A developer writes a script to create a new network by using the Cisco DNA Center API.

- A. The x-auth-token value must be changed to a valid token.
- B. The requested payload must be fixed to include missing parts.
- C. The API URL must be changed with a valid URL.
- D. Internal errors on the code of API server must be fixed.
Answer: C
NEW QUESTION # 111 
Refer to the exhibit. A developer creates a Python script by using the Cisco Meraki API. The solution must:
* Obtain a list of HTTP servers for a network named "netl".
* Print the response body if the HTTP status code is 200.
* Handle the timeout requests as exceptions, and print Timeout Error next to the exception to stdout.
Which block of code completes the script?
- A.
- B.
Answer: B
Explanation:
The block of code that correctly completes the script should handle timeout exceptions and print the error, as well as print the response body if the HTTP status code is 200. Option A achieves this:
import requests
url = 'https://api.meraki.com/api/v0/networks/net1/httpServers'
headers = { 'Accept': 'application/json' }
response = requests.get(url=url, headers=headers, verify=False, timeout=5) try:
response = requests.get(url, headers=headers, verify=False, timeout=5)
response.raise_for_status()
except requests.Timeout as e:
print("Timeout Error: {}".format(e))
if response.status_code == 200:
print(response.text)
This code makes a GET request to the specified URL, handles the timeout exception by printing a message, and prints the response body if the status code is 200.
