Answer:
The network is accesible just for the whitelisted clients configured in the switch connected to the DHCP server
Explanation:
DHCP snooping main task is to prevent an unauthorized DHCP server from entering the our network.
Basically, in the switch we define the ports on which the traffic of the reliable DHCP server can travel. That is, we define as “trust” the ports where we have DHCP servers, DHCP relays and trunks between the switches.
Binary SMS messages allow sending of various types of rich-content, such as transfering ringtones, telphone system settings and WAP-Push via text messaging. Any binary SMS message has 140 bytes of data which can be used. This data is split into two distinct parts - the user data header (UDH) and the message data.
Answer:
You should disable WPS in the access point's configuration.
Explanation:
Encryption is a form of cryptography and typically involves the process of converting or encoding informations in plaintext into a code, known as a ciphertext. Once, an information or data has been encrypted it can only be accessed and deciphered by an authorized user.
Some examples of encryption algorithms are 3DES, AES, RC4, RC5, and RSA.
In wireless access points, the encryption technologies used for preventing unauthorized access includes WEP, WPA, and WPA2.
In this scenario, you notice that an access point supports Wi-Fi Protected Setup (WPS) using a PIN and you are concerned about the security implications of this functionality. Therefore, to reduce this risk you should disable Wi-Fi Protected Setup (WPS) in the access point's configuration.
This ultimately implies that, the wireless access point will operate in an open state and as such would not require any form of password or PIN for use.
Answer:
B) False
Explanation:
The term Change control is a systematic way employed to keep track of all changes made to a product or system. It is aimed at ensuring that no unnexpected changes takes place and that changes made during application development are properly recorded.
