Cisco 200-301 Exam - Topic 15 Question 77 Discussion

Configure IPv4 and IPv6 connectivity between two routers. For IPv4, use a /28 network from the 192.168.1.0/24 private range. For IPv6, use the first /64 subnet from the 2001:0db8:aaaa::/48 subnet.1.

Actual exam question for Cisco's 200-301 exam
Question #: 77
Topic #: 15
[All 200-301 Questions]

Configure IPv4 and IPv6 connectivity between two routers. For IPv4, use a /28 network from the 192.168.1.0/24 private range. For IPv6, use the first /64 subnet from the 2001:0db8:aaaa::/48 subnet.

1. Using Ethernet0/1 on routers R1 and R2, configure the next usable/28 from the 192.168.1.0/24 range. The network 192.168.1.0/28 is unavailable.

2. For the IPv4 /28 subnet, router R1 must be configured with the first usable host address.

3. For the IPv4 /28 subnet, router R2 must be configured with the last usable host address.

4. For the IPv6 /64 subnet, configure the routers with the IP addressing provided from the topology.

5. A ping must work between the routers on the IPv4 and IPv6 address ranges.

Suggested Answer: A

Answer as below configuration:

on R1

config terminal

ipv6 unicast-routing

inter eth0/1

ip addre 192.168.1.1 255.255.255.240

ipv6 addre 2001:db8:aaaa::1/64

not shut

end

copy running start

on R2

config terminal

ipv6 unicast-routing

inter eth0/1

ip address 192.168.1.14 255.255.255.240

ipv6 address 2001:db8:aaaa::2/64

not shut

end

copy running start

---------------------

for test from R1

ping ipv6 2001:db8:aaaa::1

for test from R2

ping ipv6 2001:db8:aaaa::2

Yup, and don’t forget to check the pings after config!

R1 should get 192.168.1.17 and R2 should have 192.168.1.30, right?

Wait, are we really using 2001:0db8:aaaa::/48? Seems a bit outdated.

I recall that for the IPv6 part, we just take the first /64 from the 2001:0db8:aaaa::/48, but I need to confirm the exact addresses we should assign to R1 and R2.

For R2, I believe the last usable address would be 192.168.1.30, but I’m a bit confused about how to calculate that correctly.

I think the first usable host for R1 should be 192.168.1.17, but I need to double-check that against the subnetting rules we went over.

I remember we practiced subnetting, but I'm not entirely sure what the next usable /28 is since 192.168.1.0/28 is out.

Okay, let me think this through step-by-step. First, I need to find the next usable /28 subnet from 192.168.1.0/24, which means I'll need to calculate the network, broadcast, and usable host addresses. Then I'll assign the first and last usable host IPs to the routers. For the IPv6 part, I just need to use the provided /64 subnet. I think I can do this, but I'll double-check my work to be sure.

This looks like a good opportunity to demonstrate my IPv4 and IPv6 configuration skills. I'm confident I can handle this, as long as I take the time to carefully plan out the addressing and make sure I meet all the requirements. The key will be paying close attention to the details in the question.

Hmm, I'm a bit unsure about how to determine the next usable /28 subnet from the 192.168.1.0/24 range. I'll need to double-check my subnetting skills to make sure I get that part right. The IPv6 configuration seems more straightforward, but I want to be careful to follow the instructions exactly.

Okay, this looks like a pretty straightforward IPv4 and IPv6 configuration task. I'll need to carefully calculate the next usable /28 subnet from the 192.168.1.0/24 range, and then assign the first and last usable host addresses to the routers. For the IPv6 part, I'll just need to use the provided /64 subnet from the 2001:0db8:aaaa::/48 range.

This seems straightforward enough. I'll just carefully read through each option, think about how Alibaba Cloud Log Service works, and choose the 3 that seem like the most significant charges. Shouldn't be too tricky if I stay focused.

I think this question is asking about the role of supervisors in the job analysis process. The key seems to be that supervisors can provide important validation and a more objective perspective compared to just relying on incumbent input.

If I remember correctly, the GREP tool is not limited to just installation; I thought it could be used in other scenarios too, especially for log analysis.

And for the IPv6 /64 subnet, we need to configure the routers with the IP addressing provided from the topology. I hope the diagram is clear and easy to follow.

For the IPv4 /28 subnet, router R1 needs to be configured with the first usable host address, and router R2 needs to be configured with the last usable host address. That's a bit of a brain-teaser.
