rip R1(configrouter) version 2 R1(configrouter) work QUESTION 240 A work administrator wants to ensure that only the server can connect to port Fa0/1 on a Catalyst switch. The server is plugged into the switch Fa0/1 port and the work administrator is about to bring the server online. What can the administrator do to ensure that only the MAC address of the server is allowed by switch port Fa0/1? (Choose two.) A. Configure port Fa0/1 to accept connections only from the static IP address of the server. B. Employ a proprietary connector type on Fa0/1 that is inpatible with other host connectors. C. Configure the MAC address of the server as a static entry associated with port Fa0/1. D. Bind the IP address of the server to its MAC address on the switch to prevent other hosts from spoofing the server IP address. E. Configure port security on Fa0/1 to reject traffic with a source MAC address other than that of the server. F. Configure an access list on the switch to deny server traffic from entering any port other than Fa0/1. QUESTION 241 The interwork infrastructure of pany XYZ consists of a single OSPF area as shown in the graphic. There is concern that a lack of router resources is impeding interwork performance. As part of examining the router resources, the OSPF DRs need to be known. All the router OSPF priorities are at the default and the router IDs are shown with each router. Which routers are likely to have been elected as DR? (Choose two.) A. Corp1 B. Corp2 C. Corp3 D. Corp4 E. Branch1 F. Branch2 QUESTION 242 At which layers of the OSI model do WANs operate? (Choose two.) A. application layer B. session layer C. transport layer D. work layer E. datalink layer F. physical layer QUESTION 243 Which routing protocols can be used within the enterprise work shown in the diagram? (Choose three.) A. RIP v1 B. RIP v2 C. IGRP D. OSPF E. BGP F. EIGRP QUESTION 244 Refer to the graphic. R1 is unable to establish an OSPF neighbor relationship with R3. What are possible reasons for this problem? (Choose two.) A. All of the routers need to be configured for backbone Area 1. B. R1 and R2 are the DR and BDR, so OSPF will not establish neighbor adjacency with R3. C. A static route has been configured from R1 to R3 and prevents the neighbor adjacency from being established. D. The hello and dead interval timers are not set to the same values on R1 and R3. E. EIGRP is also configured on these routers with a lower administrative distance. F. R1 and R3 are configured in different areas. QUESTION 245 Which statements are true about EIGRP successor routes? (Choose two.) A. A successor route is used by EIGRP to forward traffic to a destination. B. Successor routes are saved in the topology table to be used if the primary route fails. C. Successor routes are flagged as active in the routing table. D. A successor route may be backed up by a feasible successor route. E. Successor routes are stored in the neighbor table following the discovery process. QUESTION 246 CCNA考试报名 1700元 112 艾迪飞论坛 to the diagram. All hosts have connectivity with one another.
