Answer:
TTL
Explanation:
TTL means time -to- live field is a counter that is designed to keep packets from circulating indefinitely in the network case forwarding tables accidentally create cycles. An IP datagram is typically initialized with a TTL of 60 or 64 and the TTL is decremented by one each time it enters a router. If the TTL reaches zero, the router will discard the packet. It is one of the components of the IP datagram
Question options:
a. RAID 0
b. RAID 1
c. RAID 5
d. RAID 6
e. RAID 10
Answer:
d. RAID 6
Explanation:
RAID is Redundant Array of Inexpensive/Independent Disks. RAID combines low cost physical hard disk drives in one hard disk drive. RAID is used to achieve data redundancy(data backup but with synchronization) or improved performance or both.
To get what the director requires he would need to use RAID 6. RAID 6 is RAID level optimized to achieve data redundancy but with slow performance.
Neither are correct.
Resistance is opposition to CURRENT not power.
Technition B Is wrong about the voltage thingy.
Answer: A. A method of access control that allows a user to log on to a system and gain access to other resources within the network via the initial logon
Explanation: key distribution center ( KDC) is a system that is used to provide access to a particular network user who shares data which are either private or regarded as sensitive.
It is a form of encryption that allows multiple system within the same network through the use of uniquely secured tickets used to setup a secure connection which gives room for data to be shared.
KDC makes use of cryptographic techniques to prove the validity of a user and grants a ticket permission access. The user present the ticket of permission to the system which then validates it and grant access to the user.
Example of security system that adopts KDC include kerberos.
