Explanation / Answer
8.answer: option D
Explanation: APIPA automatically assigns the host an IP address in the range of 169.254.0.0 to 169.254.255.254.
9.answer: option D
Explanation: for a.b.c.d/26 mask is : 255.255.255.192
10.answer: option B
Explanation: for mask 255.255.255.248: ipv4 CIDR address is a.b.c.d/29
11.answer option B
Explanation: 3 bits squared for the subnets and 5 bits squared for the hosts minus 2 for the subnet and broadcast address
12.answer: option C
Explanation: for a.b.c.d/29 ipv4 CIDR there are 8 hosts
13.answer: option A(True)
Explanation: gain/loss =10 log (Poutput / Pinput)
It is often expressed using the logarithmic decibel (dB) units
