- 29. The following figure shows the IP addresses of t he interfaces connecting routers R1, R2, and R3. A static route is configured on R1 using the com mand ip route-static 10.0.23.0 24 10.0.13.3, so th at the IP address 10.0.23.3 of GE0/0/2 on R3 can be pinged from R1. To prevent the communicati on failure between R1 and R3 in the event of the link between them becoming faulty, a backup lin k to 10.0.23.3 needs to be configured. Which of t he following commands should be used to confi gure the backup link? A. [R1] ip route-static 10.0.23.0 24 10.0.12.2 preference 40 B. [R1] ip route-static 10.0.23.0 24 10.0.12.2 preference 80 C. [R1] ip route-static 10.0.23.0 24 10.0.12.2 preference 40 [R3] ip route-static 10.0.12.0 24 10.0.23.2 D.

Match the addresses that will be used in the IP packet and the ethernet frame sent from Computer A. Computer A IP address: 178.23.43.12 Netmask: 255.255.0.0 Default gateway address: 178.23.17.1 MAC Address: 34:2A:C6:C6:55:C3 Computer E IP address: 178.23.54.23 Netmask: 255.255.0.0 Default gateway address: 178.23.10.1 MAC Address: 34:2A:C6:76:3E:12 Default Gateway MAC Address: 65:D3:C9:11:C5:99 Items to Match: IP packet Source IP address: IP packet Destination IP address: Ethernet frame Source MAC address Ethernet frame Destination MAC address Possible Values: 178.23.17.1 178.23.10.1 178.23.43.12 178.23.54.23 34:2A:C6:C6:55:C3 65:D3:C9:11:C5:99 34:2A:C6:76:3E:12Let’s consider you have a Class C IP address 204.15.5.0/24. You have to determine whether it is possible to createfollowing network with the given IP address? If yes, what could be the possible ranges of IP addresses for thesubnetworks? Let’s consider the above network. If you are using VLSM /CIDR, determine what subnet mask numbers allow therequired number of hosts.
- After establishing a connection with the local DNS server PC1 now knows the IP and MAC addresses of PC2. Suppose PC1 [IP Address: 192.168.2.1, MAC Address: 0010.1191.A946] is sending an ARP packet to PC2 [IP Address: 192.168.2.2, MAC Address: 0110.1290.AD23]. What will be written in the target MAC address before the packet reaches PC2 ?. Assume: Your laptop's Ethernet address is 0a:0b:0c:0d:0e:0f, DHCP server address is 131.111.7.3, your IPv4 address will be 131.111.7.121, the gateway's IP address is 131.111.7.1, and Ethernet address is 00:01:02:03:04:05, the network subnet mask is 255.255.255.0.Write the series of protocol/packet exchanges that occur on the wired Ethernet link, up until you can send a single packet to 128.232.0.20. You do not need to describe packets after this packet has left the link. Include ARP and DHCPA Network with id: 192.168.0.0 and subnet mask 255.255.0.0 is given to you to split it in such a way thatfollowing classrooms are given adequate number of IPs based on their needs. Each classroom willoccupy its own subnet. The following information for each subnet must be included: Subnet ID CIDR Subnet Mask First IP usable in the subnet Last IP usable in the subnet Broadcast IP Address for the subnet Classroom1: 8 PCsClassroom2: 400PC and 4 PrinterClassroom 3: 2 PCsClassroom4: 62 PCs and a ServerClassroom5: 24PCs
- In the context of DHCP what is the purpose of an IP helper address? a. The gateway for the computers in the segment b. Used to map private addresses in public ones for the purpose of accessing the outside c. Allows routers to forward DHCP requests to the segment where the server can be found d. It is a temporary IP address used by end-devices to issue requests to the DHCP serverA router running Classless Interdomain Routing (CIDR) has the following entries in its routing table: Address/mask Next hop 135.46.56.0/22 Interface 0 135.46.60.0/22 Interface 1 192.53.40.0/23 Router 2 Default Router 3 How does a CIDR router work to route the packets it received? For each of the following IP addresses, what will the router do if a packet with that address arrives? (a) 135.46.63.10 (b) 135.46.58.16 (c) 135.46.52.2 (d) 192.53.40.7 (e) 192.53.56.7Given the following network: 192.168.10.0/24. Subnet this network with a /25 subnet mask. Answer the following questions: What is the class of the 192.168.10.0/24? Using/25, how many networks are available? Using/25, how many valid hosts per network are available? Using/25, what is the subnet mask? Using/25, what is the broadcast address?
- Given the topology below, write the commands to advertise the OSPFv3 networks on the Sohar router. Use the following requirements: - Enable IPv6 routing- Process ID 10 - Router IDs (Sohar router = 2.2.2.2) - Advertise Network address for each interface - LAN interface (G0/0) set to passive interface - Assign Link-Local Addresses (fe80::1) to G0/0Given an IP Block 192.168.0.0/24 you were asked to create 32 subnet with 6 host each subnet 1. How many bits from host become part of the network address? 2. What are the subnet addresses? 3. What is the 1st useable ip address of the 2nd subnet 4. What is the broadcast address of the last subnet? 5. What are usable ip address of the 1st subnet ?Supposed the scenario bellow, we have 3 networks to be submitted with the ip address 192.171.0.0/16.
