Questions

Answer the following questions to test your knowledge of this chapter:

1. What is the core network?
   1. The network that connects the servers to the internet
   2. The center of the network that connects the data center(s) and the user networks
   3. A general term for an enterprise network
   4. The network between the users and the internet
2. In Figure 1.5, on the left, we can see a typical network topology. In this network, assuming they are on the same IP subnet, when PC1 pings PC5, the packets are forwarded through which of the following?
   1. Access switch ACC1, distribution switch DIST1, core switches CORE1 and CORE2, data center switches DC1 and DC2, distribution switch DIST2, and access switch ACC4.
   2. Access switch ACC1, distribution switch DIST1, core switches CORE1 and CORE2, distribution switch DIST2, and access switch ACC4.
   3. Answers (a) and (b) can both be correct, depending on the routing configuration.
   4. Answers (a) and (b) can both be correct, depending on the HSRP configuration.
3. In the same figure (Figure 1.5) on the left, PC1 pings PC4. The packets will go through which of the following?
   1. ACC1, DIST1, CORE1, DIST2, and ACC3
   2. ACC1, DIST1, CORE2, DIST2, and ACC3
   3. ACC1, DIST1, CORE1, CORE2, DIST2, and ACC3
   4. ACC1, DIST1, CORE1, DC1, DC2, CORE2, DIST2, and ACC3
4. Assuming PC1 is in VLAN50 and PC2 is in VLAN60, pings are sent from PC1 to PC2. Routing will be performed on which of the following?
   1. The left network is on CORE1 and the right network is on DC1.
   2. The left network is on CORE1 or CORE2, and the right network is on DC1 or DC2, depending on the routing protocol configuration.
   3. The left network is on CORE1 and the right network is on DC2.
   4. The left network is on CORE1 or CORE2, and the right network is on DC1 or DC2, depending on HSRP configuration.
5. In Figure 1.8, on the left, the packets from PC4 that are sent to the servers will be forwarded through which of the following?
   1. ACC3, DIST2, CORE2, and DC2
   2. ACC3, DIST2, CORE2, FW2, DC2, and FW1
   3. ACC3, DIST2, CORE2, FW2, and DC2
   4. Any of the above, depending on the routing configuration.
6. Which of the following is a characteristic of attacks that target the data plane?
   1. Changing routing tables to divert packets in the attacker's direction
   2. Flooding the network to stop users from using it
   3. Taking control of the device's console to change its configuration
   4. All the above
7. Which of the following is a characteristic of attacks that target the control plane?
   1. Changing routing tables to divert packets toward the attacker's direction
   2. Flooding the network to stop users from using it
   3. Taking control of the device's console to change its configuration
   4. All the above
8. What are DDoS attacks?
   1. Attacks that prevent access to the network
   2. Attacks that prevent access from network servers
   3. Attacks that prevent access from network services
   4. All of the above
