Cookie — Test 1

Correct Answer: A. A. Cookie
Explanation: The cookie property sets or returns all name/value pairs of cookies in the current document. There are no methods involved: cookies are queried, set, and deleted by reading and writing the cookie property of the Document object using specially formatted strings.

Correct Answer: D. D. Transient
Explanation: Cookies are transient by default; the values they store last for the duration of the web browser session but are lost when the user exits the browser. While the browsing session is active the cookie stores the user values in the user’s storage itself and accesses them.

Correct Answer: C. C. Max-age
Explanation: If you want a cookie to last beyond a single browsing session, you must tell the browser how long (in seconds) you would like it to retain the cookie by specifying a max-age attribute. A number of seconds until the cookie expires. A zero or negative number will kill the cookie immediately.

Correct Answer: D. D. All of the mentioned
Explanation: sessionStorage, localStorage and Document path all are used to store data on the client-side. Each one has its own storage and expiration limit. Cookie visibility is scoped by the document origin as Local Storage and Session Storage are, and also by document path.

Correct Answer: C. C. Both path and domain
Explanation: The Cookie visibility scope is configurable through cookie attributes path and domain. Domain attribute in the cookie is used to specify the domain for which the cookie is sent. Path includes the Path attribute in the cookie to specify the path for which this cookie is sent.

Correct Answer: B. B. Secure
Explanation: The final cookie attribute is a boolean attribute named secure that specifies how cookie values are transmitted over the network. By default, cookies are insecure, which means that they are transmitted over a normal, insecure HTTP connection. If a cookie is marked secure, however, it is transmitted only when the browser and server are connected via HTTPS or another secure protocol.

Correct Answer: A. A. Encodeuricomponent()
Explanation: Cookie values cannot include semicolons, commas, or whitespace. For this reason, you may want to use the core JavaScript global function encodeURIComponent() to encode the value before storing it in the cookie.

Correct Answer: C. C. 4 kb
Explanation: Each cookie can hold up to only 4 KB. In practice, browsers allow many more than 300 cookies total, but the 4 KB size limit may still be enforced by some. Storage of a session has to be a minimum of 5MB.

Correct Answer: B. B. Server side programming
Explanation: Cookies were originally designed for server side programming, and at the lowest level, they are implemented as an extension to the HTTP protocol. They were introduced with the intention of providing a better user experience for the websites.

Correct Answer: A. A. /
Explanation: Setting the path of a cookie to “/” gives scoping like that of localStorage and also specifies that the browser must transmit the cookie name and value to the server whenever it requests any web page on the site.
