Correct!   3   2   1 See Chapter 7.   Question 2 2 / 2 pts (TCO 5) The passive-interface command is used to _____. Correct!   prevent forming neighbor adjacencies   prevent routing table updates   shutdown interfaces   active interfaces See Chapter 7.   Question 3 2 / 2 pts (TCO 5) EIGRP routers establish adjacencies with other routers by exchanging _____ packets. Correct!   hello   router   adjacency   LSA See Chapter 7.   Question 4 2 / 2 pts (TCO 5) EIGRP uses what two main metrics?   Reliability, load   Load, bandwidth Correct!   Bandwidth, delay   Delay, hop count See Chapter 7.   Question 5 2 / 2 pts (TCO 5) In the router eigrp 1 command, what does the value 1 represent? Correct!   The EIGRP process   The base network   Area 0   Nothing See Chapter 7.   Question 6 2 / 2 pts (TCO 5) Using the default metric values the metric calculation can be simplified to the slowest bandwidth and the _____of all the delays.   Difference Correct!   Sum   Average   Delay is not a default metric See Chapter 7.   Question 7 2 / 2 pts (TCO 5) Which of the following conditions occurring simultaneously will result in an EIGRP route going into the active state? Correct!   The successor is down.   The network has been recalculated.   One neighbor has not met the feasibility condition.   The router is not sending queries. See Chapter 7.   Question 8 2 / 2 pts (TCO 5) With a partial update EIGRP is sending what? Correct!   Only includes information about the route changes   Only part of the topology table   The entire routing table   Everything except the subnet mask See Chapter 7.   Question 9 Not yet graded / 4 pts (TCO 5) Explain partial and bounded updates. Your Answer: The term  partial  means that the update only includes information about the route changes. The term  bounded  refers to the propagation of partial updates that are sent only to those routers that the changes affect. By sending only the routing information that is needed only to those routers that need it, EIGRP minimizes the bandwidth that is required to send EIGRP updates. (Academy 371) Academy, Cisco N.  Scaling Networks Companion Guide . Pearson Learning Solutions, 03/2014. VitalBook file. See Chapter 7. -EIGRP uses the terms partial updates and bounded updates when referring to its updates.  -Unlike RIP, EIGRP does not send periodic updates and route entries do not age out.  -The term partial means that the update only includes information about the route changes, such as a new link or a link becoming unavailable.  -The term bounded refers to the propagation of partial updates that are sent only to those routers that the changes affect.  -This minimizes the bandwidth that is required to send EIGRP updates. Quiz Score:  20  out of 20 Week 7   Question 1 2 / 2 pts (TCO 5) By default, EIGRP uses what percent of the available bandwidth? Correct!   50   100   10   None See Chapter 8.   Question 2

Week 1 Lab: Switching Review & Multi-Layer Switching This week you will be working with Switching as a review of your class material from NETW204 and as an introduction to the new material introduced in Week 1 and Chapter 1 of this course. This week you were introduced to the Cisco hierarchical network design model. In addition, you will be using this model as a way to organize the equipment selection for the course project in this class. Your Skillsoft lab covers multi-layer switching including exercises on multi-layer switching using Layer 3 ports, and using SVIs. Answer the following questions: 1. Discuss the role of each layer in the hierarchical network model. (1 point) The access layer provides connectivity for the users. The distribution layer is used to forward traffic from one local network to another. Finally, the core layer represents a high-speed backbone layer between dispersed networks. 2. What are three roles of the hierarchical model’s core layer? (1 point) The core layer is the layer that helps with the transportation of data across the network in a fast and reliable manner. This layer is also known as the backbone, or foundation network because all other layers rely on it. The various factors involved in designing devices for the core layer are high data transfer rates, a low latency period, and high reliability. 3. What are the major functional areas in the Cisco Network Architectures for Enterprise? Describe each area. (1 point) Enterprise Campus:The enterprise campus functional area is intended to be the center of the network design, located at a single location where several different core elements are located and are accessed from all other parts of the network. There are several different technologies and components located at this part of the network, including routing, switching, firewalls, intrusion detection and prevention systems, voice, video, access control, among others. Enterprise Edge:The enterprise edge functional area is responsible for the aggregation of several different off-campus elements as well as the routing of this traffic into the campus core module within the Enterprise Campus Functional area. Service Provider Edge:The service provider functional area is responsible for connectivity into Service Provider networks. This includes a number of different connectivity options, from Internet access through Public Switched Telephone Network (PSTN) access.

Correct Answer   hierarchical network design   flat network design   designated routers You Answered   the number of SPF calculations required See Chapter 6.   Question 2 2 / 2 pts (TCO 4) In multi-area OSPF all areas must connect to the _____.   MBone area Correct!   backbone area   headquarters area   designated router See Chapter 6.   Question 3 2 / 2 pts (TCO 4) This command shows the multi area OSPF link state database.   show database   show ip ospf lsa   show ospf areas Correct!   show ip ospf database See Chapter 6.   Question 4 2 / 2 pts (TCO 4) A regular area is _____.   a backbone area   not used in multi-area OSPF Correct!   a nonbackbone area   Area 0 See Chapter 6.   Question 5 2 / 2 pts (TCO 4) On which type of OSPF routers can route summarization be configured? Correct!   ABR   PDQ   ARSI   Internal See Chapter 6.   Question 6 2 / 2 pts (TCO 4) Why would you use multi-area OSPF?   You have been assigned an autonomous system number.   You have expanded your operations outside of your home country.   SPF computations are decreasing. Correct!   SPF computations are growing. See Chapter 6.   Question 7 2 / 2 pts (TCO 4) In a multi-area OSPF network the main area is Area ____. Correct!   0   DR   255   1 See Chapter 6.   Question 8 2 / 2 pts (TCO 4) The propagation of OSPF message concerning routes to networks outside the OSPF AS is controlled by _____.   LSA Type 3 Correct!   LSA Type 5   LSA Type 4   LSA Type 2   LSA Type 1 See Chapter 6.   Question 9 4 / 4 pts (TCO 4) List and describe the types of OSPF routers. Your Answer: 1. Internal router – This is a router that has all of its interfaces in the same area. All internal routers in an area have identical LSDBs.  2. Backbone router –This is a router which resides in backbone area. The backbone area is set to area 0.  3. Area Border Router (ABR)- This is a router that has interfaces attached to 2 or more areas. It can route between areas. ABRs are exit points for the area, which means that routing information destined for another area can get there only via the ABR of the local area. ABRs can be configured to summarize the routing information from the LSDBs of their attached areas. ABRs distribute the routing information into the backbone. In a multiarea network, an area can have one or more ABRs.  4. Autonomous System Boundary Router (ASBR)- This is a router that has at least one interface attached to external network (other autonomous system), such as a non-OSPF network. An ASBR can import non-OSPF network information to the OSPF network using route redistribution. http://www.ipwithease.com/ospf-router-types/ (Links to an external site.)Links to an external site.   See Chapter 6. Internal router: This is a router that has all of its interfaces in the same area. All internal routers in an area have identical LSDBs. Backbone router: This is a router in the backbone area. Generally, the backbone area is set to area 0. Area border router (ABR): This is a router that has interfaces attached to multiple areas. It must maintain separate LSDBs for each area it is connected to, and it can route between areas. ABRs are exit points for the area, which means that routing information destined for another area can get there only through the ABR of the local area. ABRs can be configured
