A 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) 192.53.56.7
Three-way handshake is used by a TCP client and a TCP server to establish a connection, as illustrated below: 1st: client:port1 -> server:port2, SYN 2nd: server:port2 -> client:port1, SYNACK 3rd: client:port1 -> server:port2, ACK When this client is performing scanning attacks, it will generated a large number of failed connections. In each failed connection, the three-way handshake fails to complete. People commonly use SYN together with the absence of its corresponding SYNACK in this same TCP session to identify whether this connection is failed. By investigating the failed connections, an engineer finds that in legitimate/benign cases, if the server does not return SYNACK to the client, the client will not send the ACK packet after SYNACK (e.g., the 3rd packet above). Therefore, this engineer suggests that we can count the failed connections based on the following rules without considering SYNACK:
SMTP (Simple Mail Transfer Protocol) is the standard protocol for transferring mail between hosts. A TCP connection is set up between a user agent and a server program. The server listens on TCP port 25 for incoming connection requests. The user end of the connection is on a TCP port number above 1023. You have defined the packet filter rule set shown in the table below. These rules permit and/or deny inbound and outbound traffic between the user agent and the mail server. Describe the purpose of each packet filter rule in the table. Rule Direction Source Address Destination Address Protocol Destination Port Action A2 In External Internal TCP 25 Permit B2 Out Internal External TCP > 1023 Permit C2 Out Internal External TCP 25 Permit D2 In External Internal TCP > 1023 Permit E2 Either Any Any Any Any Deny
Q: Imagine a Web server that maintains a table in which client IP addresses are mapped to the most recently accessed Web pages. When a client connects to the server, the server looks up the client in its table, and if found, returns the registered page. Is this server stateful or stateless?
QUESTION 13 Fill the blank With the TCP server, there is a welcoming socket, and each time a client initiates a connection to the server, a new socket is created. Thus, to support n simultaneous connections, the server would need sockets. O n-1 On O n+1 01

Ethernet, for example, is a connectionless protocol that specifies the path taken by a packet between its source and destination addresses. However, a protocol that is connection-oriented, such as ATM, specifies the path taken by a cell using virtual connection IDs (VPIs and VCIs). Could you please elaborate on this statement?
Consider the following virtual circuit network with three reserved virtual circuits: уC1: H1, А, С, Е, Н2 VC2: H3, A, F, D, H4 ус3: НЗ, А, F, D, E, H2 Host H4 Host H3 Нost H2 Host H1 Draw the routing table of router D and the routing table of router C. *you may design a table using the HTML editor or write the content of routing table record by record (record per line).

Implement in Packet Tracer a network of a fictitious organization with the following characteristics: - The organization will be made up of 4 units: 3 local Ethernet networks + 1 remote Ethernet network (via the Internet)- Local dependencies must connect to each other through a Backbone (links) between Switches- There must be 2 VLANs in 2 local dependencies- Throughout the organization there must be 2 IP networks with 2 subnets each. The different IP networks must communicate with each other.- A static routing method or a dynamic routing method must exist- The remote unit must be integrated into some IP network through a VPN link- Each local office must have IP telephony (VoIP). At least one IP phone for each unit.- In each unit there must be at least 5 user PCs- Each PC must have Automatic IP configuration (DHCP)- DHCP, DNS and Web Servers must exist - All rooms must have access to the Internet through NAT-PAT- There must be a Wi-FI network in each unit
