Trắc nghiệm về công nghệ thông tin 2 Shared by www.ccna4u.org www.ccna4u.net www.ccna4u.info www.ccna4u.tkTake Assessment - ERouting Final Exam - CCNA Exploration: Routing Protocols and Concepts (Version 4.0) 00:54:12 Time Remaining:1 Refer to the exhibit. A network administrator is troubleshooting the OSPF network. The 10.10.0.0/16 network is not showing up in the routing table of Router1. What is the probable cause of this problem? The serial interface on Router2 is down. The OSPF process is not running on Router2. 1 Shared by www.ccna4u.org www.ccna4u.net www.ccna4u.info www.ccna4u.tk The OSPF process is configured incorrectly on Router1. There is an incorrect wildcard mask statement for network 10.10.0.0/16 on Router2. 2 Which of the following could describe the devices labeled ? in the graphic? (Choose three.) DCE CSU/DSU LAN switch modem hub3 Using default settings, what is the next step in the router boot sequence after the IOS loads from flash? Perform the POST routine. Search for a backup IOS in ROM. Load the bootstrap program from ROM. Load the running-config file from RAM. Locate and load the startup-config file from NVRAM. 4 2 Shared by www.ccna4u.org www.ccna4u.net www.ccna4u.info www.ccna4u.tk Refer to the exhibit. What are two of the routes added to the routing table of R1? (Choose two.) R 172.16.1.0/24 [120/1] via 192.168.3.0, 00:00:24, Serial0/0/0 R 192.168.1.0/24 [120/1] via 172.16.2.1, 00:00:24, Serial0/0/1 R 192.168.9.0/24 [120/1] via 172.16.1.2, 00:00:24, Serial0/0/0 R 192.168.100.0/24 [120/1] via 172.16.1.1, 00:00:24, Serial0/0/0 R 192.168.2.0/24 [120/1] via 172.16.1.2, 00:00:24, Serial0/0/05 Which statement is true regarding routing metrics? All routing protocols use the same metrics. EIGRP uses bandwidth as its only metric. Routers compare metrics to determine the best route. The larger metric generally represents the better path. 3 Shared by www.ccna4u.org www.ccna4u.net www.ccna4u.info www.ccna4u.tk6 Refer to the exhibit. Routers R1 and R3 use different routing protocols with default administrative distance values. All devices are properly configured and the destination network is advertised by both protocols. Which path will be used to transmit the data packets between PC1 and PC2? The packets will travel via R2-R1. The packets will travel via R2-R3. The traffic will be load-balanced between two paths — via R2-R1 and via R2-R3. The packets will travel via R2-R3, and the other path via R2-R1 will be retained as the backup path. 4 Shared by www.ccna4u.org www.ccna4u.net www.ccna4u.info www.ccna4u.tk7 Refer to the exhibit. Which combination of IP address and subnet mask can be used on the serial interface of Router2 in order to put the interface in the same network as the serial interface of Router1? IP 172.16.0.18, subnet mask 255.255.255.0 IP 172.16.32.15, subnet mask 255.255.255.240 IP 172.16.0.18, subnet mask 255.255.255.252 IP 172.16.32.18, subnet mask 255.255.255.252 8Which two technologies can be used in distance vector routing protocols to prevent routing loops? (Choose two.) authentication link-state advertisements hold-down timers Spanning Tree Protocol split horizon9 A network administrator is in charge of two separate networks that share a single building. What device will be required to connect the two networks and add a common connection to the Internet that can be shared? hub router access point 5 Shared by www.ccna4u.org www.ccna4u.net www.ccna4u.info www.ccna4u.tk Ethernet switch 10 Refer to the exhibit.
