Question # 177

An engineer must update the configuration on two PCs in two different subnets to communicate locally with each other. One PC is configured with IP address 192.168.25.128/25 and the other with 192.168.25.100/25. Which network mask must the engineer configure on both PCs to enable the communication?

255.255.255.224

255.255.255.248

255.255.255.0

Question # 179

Connectivity between four routers has been established. IP connectivity must be configured in the order presented to complete the implementation. No dynamic routing protocols are included.

1. Configure static routing using host routes to establish connectivity from router R3 to the router R1 Loopback address using the source IP of 209.165.200.230.

2. Configure an IPv4 default route on router R2 destined for router R4.

3. Configure an IPv6 default router on router R2 destined for router R4.

Question # 180

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.

Question # 184

All physical cabling is in place. Router R4 and PCI are fully configured and

inaccessible. R4's WAN interfaces use .4 in the last octet for each subnet.

Configurations should ensure that connectivity is established end-to-end.

1 . Configure static routing to ensure RI prefers the path through R2 to

reach only PCI on R4's LAN

2. Configure static routing that ensures traffic sourced from RI will take

an alternate path through R3 to PCI in the event of an outage along

the primary path

3. Configure default routes on RI and R3 to the Internet using the least number of hops

Explanation:

To configure static routing on R1 to ensure that it prefers the path through R2 to reach only PC1 on R4â€™s LAN, you need to create a static route for the host 10.0.0.100/8 with a next-hop address of 20.0.0.2, which is the IP address of R2â€™s interface connected to R1. You also need to assign a lower administrative distance (AD) to this route than the default AD of 1 for static routes, so that it has a higher preference over other possible routes. For example, you can use an AD of 10 for this route. To create this static route, you need to enter the following commands on R1â€™s console:

R1#configure terminal R1(config)#ip route 10.0.0.100 255.0.0.0 20.0.0.2 10 R1(config)#end

To configure static routing on R1 that ensures that traffic sourced from R1 will take an alternate path through R3 to PC1 in the event of an outage along the primary path, you need to create another static route for the host 10.0.0.100/8 with a next-hop address of 40.0.0.2, which is the IP address of R3â€™s interface connected to R1. You also need to assign a higher AD to this route than the AD of the primary route, so that it has a lower preference and acts as a backup route. For example, you can use an AD of 20 for this route. This type of static route is also known as a floating static route. To create this static route, you need to enter the following commands on R1â€™s console:

R1#configure terminal R1(config)#ip route 10.0.0.100 255.0.0.0 40.0.0.2 20 R1(config)#end

To configure default routes on R1 and R3 to the Internet using the least number of hops, you need to create a static route for the network 0.0.0.0/0 with a next-hop address of the ISPâ€™s interface connected to each router respectively. A default route is a special type of static route that matches any destination address and is used when no other specific route is available. The ISPâ€™s interface connected to R1 has an IP address of 10.0.0.4, and the ISPâ€™s interface connected to R3 has an IP address of 50.0.0.4. To create these default routes, you need to enter the following commands on each routerâ€™s console:

On R1: R1#configure terminal R1(config)#ip route 0.0.0.0 0.0.0.0 10.0.0.4 R1(config)#end

On R3: R3#configure terminal R3(config)#ip route 0.0.0.0 0.0.0.0 50.0.0.4 R3(config)#end
