Redistribution Horizon c. it is imperative that one exists as the devices receive the information through the DR. Answer: False OSPF chooses a DR and BDR in order to communicate with all other devices in it’s area.learnsmartsystems. Question 89 True or False . Question 90 Which of the following was developed by Cisco in order to optimize the way the internal processes of a router determine how to forward packets? a. and increase the load on the router. BAM Answer: A CEF optimizes the internal processes of how a router forwards data.418. Question 92 True or False . Question 91 True or False . it uses the destination IP in order to determine where to send the traffic based upon the match in the routing table.When a packet is received by a router. It is turned on by default on newer devices. STP c.The larger the routing table. Answer: True Where there is a larger routing table. Tel: 1 800. RAM d. it will compare the source IP address to the routing table in order to find a match to send traffic to. Summarization is one of the tools used to decrease this load. routing look ups take a great amount of time.learnsmartsystems. the more CPU processing it requires to look up routes. The information is organized in the routing table and searched through using advanced algorithms.6789 | www. Answer: False When a packet is received. CEF b.com . Router b.6789 | www. Tel: 1 800. The default can be used to do this. and will be used if there are no other routes in the routing table that match the traffic currently being sent. Layer 2 switch d.Question 93 Which of the following are two ways in which a router makes a decision to route a packet? a. defaulting all traffic to this route if there is no match.learnsmartsystems. Manual route d. Layer 3 switch c. a static route has a better administrative distance. Question 94 True or False . Static route b. then send all traffic out to the external network. Dependent route Answer: A and B Static and dynamic routes are both used when determining a routing decision. Answer: True This situation is used a great deal in dealing how to route Internet traffic out of a company’s network. Hub Answer: A and B A router and a layer 3 switch offer layer 3 services that will route packets between broadcast domains that were segmented by installing VLANs. and therefore is believed more.418.A default route can be created that matches all traffic.com . Question 95 Which of the following two devices are needed in order to route packets between VLANs? a. If traffic does not match a destination internally. Dynamic route c. However. To choose the backup method of how to get to a route. The configuration that is loaded when the device is turned on is the startup-config.com . c.Question 96 True or False . Tel: 1 800. This can be done for many different protocols. Answer: B Routing protocols provide the best routes to destinations by dynamically learning and updating routes based on conditions in a network environment. Startup-config b. Device-config d. To statically choose the best route for traffic.Routing metrics can be manipulated manually by an administrator on a router.418. Running-config c. To dynamically choose the best route for traffic to get to a remote network. b. Answer: True The ability to manipulate the routing protocols decision on which route to take to a distant network is advantageous for many engineers. d.learnsmartsystems. Routing protocols should not be used as they are unreliable. Console-config Answer: B The configuration currently being used by a device is the running-config. Question 97 What command provides the user with the configuration currently being used by the device? a.6789 | www. Question 98 What is the purpose of a routing protocol? a. Question 99 True or False .6789 | www. Tel: 1 800. like BGP. No manual configuration is needed unless static routes are used. Question 100 True or False .When a route fails. connect one autonomous system to other autonomous systems.418. Interior gateway protocols are used to route within an autonomous system itself. to find the best next route to a particular network. Answer: False The purpose of the routing protocol is to dynamically update if a route updates. Answer: False Exterior gateway protocols.com .An exterior gateway protocol is a routing protocol used internally within one autonomous system. a routing protocol will need to be manually configured to choose the next available route by an administrator.learnsmartsystems.
