1. Without configuration management, which three issues are you likely to experience? I. Lower network performance. II. Increased time to resolve problems. III. Increased number of errors on the network. IV Higher network costs because of inefficiently used network components. V. Inability to determine the impact of network changes or outages on the enduser. A. I, II, III B. I,IV, V C. II, III, V D. III, IV, V 2. Which of the following is a rule associated with the hierarchical design model? I. Use a consistent number of layers throughout the internet work. II. Use consistent bandwidth links within each layer of the model. III. Design the core for maximum availability. IV. Implement policy and security at the access layer. A. I, III B. II, IV C. I, II, III D. I, II, III, IV 3. A large corporation has a campus network composed of the Building Access, Building Distribution, Campus Backbone, and Server Farm modules. It needs to implement a WAN connection to remote locations and support Internet access. How should the company implement the WAN and Internet connections to the campus network? A. Using Building Access switches. B. Using Building Distribution switches. C. Using Edge Distribution switches with security. D. Using multilayer Campus Backbone switches. 4. Which of the following lists best describes the biggest concerns clients have about WAN design? A. Cabling, topology, compatibility, and cost. B. Reliability, flow control, addressing, and connectors. C. Amount of traffic, data representation, cost, and standards. D. Reliability, cost, amount of traffic, and compatibility. 5. Blacknink Sdn. Bhd. has a campus network with 5 buildings. All the Blackpink servers and the central core of the network are located in Building 1. A Catalyst 6500 multilayer switch connects to each of the other buildings through a Gigabit link over a multimode fiber optic cable. Each building has a separate IP subnet with 300 to 500 devices in each. Blackpink users report some serious network performance problems. Periodically, response time becomes very slow and then increases again. The problem has been sporadic and very difficult to troubleshoot. Blackpiak uses Windows and Linux servers and Windows 10 workstations with default configurations. What change in network design would you recommend to improve performance? A. Install a layer 3 switch on each subnet. B. Implement multiple VLANs in each of the buildings. C. Install a dual Gigabit Ethernet uplinks to the buildings. D. Use single-mode fiber optic cable for the Gigabit Ethernet uplinks to the buildings. 6. The departments of a corporation are spread across several buildings, while they use common servers. Network policy and security are important. Where should the corporation place the servers and how should they be attached to the network? A. Each building should have some servers connected to the Building Distribution switches. B. The servers need to be close to users, so they are attached to the Building Access switch. C. The servers should directly connect to the data link layer switches in the Campus Backbone submodule of the network. D. The company should create a Server Farm module with its switches connected to the Campus Backbone submodule. 7. A corporate network is spread over three floors. There is one data link layer switch on each floor with more than one VLAN. One connection from each floor goes to the basement, where all WAN connections are terminated. Currently, servers are installed in each VLAN but the company will soon move the servers to the basement. Traffic between VLANs is essential. What network design should the company use? A. Connect the multilayer switch on each floor to a data link layer switch in the basement. B. Connect the data link layer switch on each floor to a multilayer switch in the basement. C. Connect the data link layer switch on each floor to a data link layer switch in the basement and the VLAN router. D. Connect the data link layer switch on each floor to a multilayer switch on the same floor for inter-VLAN communication. Which method is the most appropriate when considering an Internet connection as a secure backup solution for an Enterprise WAN link? A. IPSec tunnels. B. GRE tunnels. C. IP routing with encryption. D. IP routing without encryption. The goal of performance management is to guarantee internetwork performance at an acceptable level. Performance problems are usually related to A. capacity B. device errors C. configuration errors D. poorly designed databases 0 . Which of the following steps are involved in a network security design? I. Analysis of security risks. II. Training of users, managers, and technical staff. III. Identification of network assets. IV Identification of routing protocol metrics. V. Analysis of security requirements and tradeoffs. A. II, III, IV B. III, IV, V C. I, II, V D. I, II, III, V
