An IPv4 address consists of how many bits?
32
Which part of an IPv4 address identifies the specific device on a network?
Host portion
Which tool is used to separate the network and host portion of an IP address
Subnet Mask
A prefix length of /24 is equal to which subnet mask?
255.255.255.0
Which logical operation is used on IP addressing to determine the network
AND operation
Which of the following is NOT a type of IPv4 address
- Network address
- Broadcast address
- Host address
-MAC address
MAC address
Which type of transmission sends a packet to a single destination
Unicast
Which ipv4 is used for loopback testing
127.0.0.1
Which address range is used for private networks
172.16.0.0 – 172.31.255.255 (/12)
What does NAT do?
- Translate private IPs to public IPs
- Assign MAC address
- Encrypt IPv4 addresses
- Test TCP/IP stack
- Translate private IPs to public IPs
Class A networks use how many bits for the network portion
8 bits
Which class range is used for multicast?
Class D
The main disadvantage of classful addresssing was:
- It supported only IPv6
- It had no subnetting
- It wasted many IPv4 address
- It could not use NAT
It wasted many IPv4s address
Subnetting at /24 means how many bits are available
8 bits
Which type of traffic does ARP use?
Broadcast
A problem with large broadcast domain is:
- increased IP address
- Reduced collisions
- Excessive broadcast traffic
- More routes requred
Excessive broadcast traffic

128
How many host bits are availabe in a /8 prefix
24 bits
Which subnet mask would allow exactly 30 usable hosts
/27
A company needs 1000 subnet from 10.0.0.0/8. How many bits must be borrowed
10 bits
