Correct Answer: D. D. Simplex
Explanation: In simplex transmission, data flows in single direction which in this case refers to the data flowing from the keyboard to the computer. Another example would be of the mouse where the data flows from the mouse to the computer only.

Correct Answer: D. D. All of the mentioned
Explanation: The routing algorithm is what decides where a packet should go next. There are several routing techniques like shortest path algorithm, static and dynamic routing, decentralized routing, distance vector routing, link state routing, Hierarchical routing etc. The routing algorithms go hand in hand with the operations of all the routers in the networks. The routers are the main participants in these algorithms.

Correct Answer: D. D. Hub
Explanation: Switches, RAID arrays and tape drives are the main storage devices in SMI-S, while a Hub is simple networking device that cannot be used as storage.

Correct Answer: B. B. Debug ip rip
Explanation: The debug IP rip command is used to show the Internet Protocol (IP) Routing Information Protocol (RIP) updates being sent and received on the router. It verifies that the updates are being broadcasted and not multicasted.

Correct Answer: A. A. Web cache doesnt has its own disk space
Explanation: Web cache or also known as HTTP cache is a temporary storage where HTML pages and images are stored temporarily so that server lag could be reduced.

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.
