Answer:
a) Time to live field
b) Destination
c) Yes, they have two ip addresses.
d) 128 bits
e) 32 hexadecimal digits
Explanation:
a) the time to live field (TTL) indicates how long a packet can survive in a network and whether the packet should be discarded. The TTL is filled to limit the number of packets passing through N routers.
b) When a large datagram is fragmented into multiple smaller datagrams, they are reassembled at the destination into a single large datagram before beung passed to the next layer.
c) Yes, each router has a unique IP address that can be used to identify it. Each router has two IP addresses, each assigned to the wide area network interface and the local area network interface.
d) IPv6 addresses are represented by eight our characters hexadecimal numbers. Each hexadecimal number have 16 bits making a total of 128 bits (8 × 16)
e) IPv6 address has 32 hexadecimal digits with 4 bits/hex digit
Answer:
ISO 27002
Explanation:
The acronym ISO stand for The International Organization for Standardization. its a non governmental body that is responsible for setting standards guide internationally.
while NIST stand for National Institute of Standards and technology and it is also a body that is responsible for setting up standard guide in the US..
ISO 27002 is a standard code for implementing information security management systems. while ISO 27017 is for cloud security. NIST 800-12 is a general security and NIST 800-14 is for policy development. thus option A is correct.
Note :
All code preceded by ISO is from The International Organization for Standardization and are international standard. while those preceded by NIST is from National Institute of Standards and technology and are not international standard.
