Which network is reserved as a private network according to RFC1918?

B10.254.1.0/24

C193.168.1.0/24

D172.15.1.0/24

Show Suggested Answer

Suggested Answer: C

In an Ethernet frame carrying a VLAN tag, the VLAN tag appears before the type field. A VLAN tag is a 4-byte field that is inserted into an Ethernet frame to indicate the VLAN membership and priority of the frame. The VLAN tag consists of two subfields: the tag protocol identifier (TPID) and the tag control information (TCI). The TPID subfield is a 16-bit field that identifies the frame as an IEEE 802.1Q-tagged frame, with a value of 0x8100. The TCI subfield is a 16-bit field that contains the priority code point (PCP), the drop eligible indicator (DEI), and the VLAN identifier (VID). The VLAN tag appears between the source MAC address and the type fields of the original frame, shifting the type field by four bytes. The type field indicates the type of the payload, such as IP or ARP .

Surprised to see 172.15.1.0/24 listed here, that's public!

193.168.1.0/24? That's not even a private range!

Wait, isn't 10.0.0.0/8 also private?

Definitely 172.16.1.0/9 is private!

I feel like the answer has to be one of the 172.x options, but I can't recall if it's 172.16.1.0 or something else.

I’m a bit confused; I thought 193.168.1.0 was a private network, but it seems like it’s not in RFC1918.

I remember practicing a question about private IP ranges, and I think 172.16.1.0/9 is part of that range.

I think the private networks are 10.x, 172.16.x, and 192.168.x ranges, but I’m not sure which one is specifically mentioned in RFC1918.

I'm confident the answer is C. 193.168.1.0/24 is not a valid private network range according to RFC1918.

This seems straightforward - the 172.16.1.0/9 range is one of the private network blocks defined in RFC1918, so I'll go with that.

I'm a bit unsure on this one. I'll need to review my notes on RFC1918 to make sure I have the right private network range.

Okay, I know RFC1918 defines the private IP address ranges, so I just need to identify which one of these options matches that.

Hmm, this looks like a tricky one. I'll need to think through the RFC1918 guidelines carefully to determine the correct private network.

Okay, I think I've got this. The key is finding the two things that internal controls need to balance. Based on the answer choices, it looks like it's a choice between risk, control, productivity, and test. I'll go with the most logical pairing.

Okay, I've got a strategy here. I'll think about the different factors that could affect the application's load, like the number of users and their average usage.

Ah, this is a tricky one. I'm torn between data encryption and data control. I'll have to weigh the relative importance of those two requirements to businesses. Time to put on my critical thinking cap!

Ah, the age-old question: 'Which network is reserved as a private network?' It's like asking 'What's the meaning of life?' - the answer is always 42, right?

I bet the correct answer is D) 172.15.1.0/24. Why? Because it's the only one that doesn't sound like a valid IP address. The exam writers are tricky like that.
