By PassGuide CCNA Training Materials and Practice Tests | April 1, 2010

Cisco Certified Network Associate (CCNA®) validates the ability to install, configure, operate, and troubleshoot medium-size route and switched networks, including implementation and verification of connections to remote sites in a WAN. CCNA curriculum includes basic mitigation of security threats, introduction to wireless networking concepts and terminology, and performance-based skills. This new curriculum also includes (but is not limited to) the use of these protocols: IP, Enhanced Interior Gateway Routing Protocol (EIGRP), Serial Line Interface Protocol Frame Relay, Routing Information Protocol Version 2 (RIPv2),VLANs, Ethernet, access control lists (ACLs).Question:420

Question:422
Refer to the exhibit.SO/O on R1 is configured as a multipoint interface to communicate with R2.
And R3 in this hub-anD.spoke Frame Relay topology. While testing this configuration, a technician notes that pings are successful from hosts on the 172.16..1.0/24 network to hosts on both the 172.16.2.0/25 and
172.16.2.128.25 net works.However.pings between hosts on the 172.16.2.0/25 and 172.16.2.12B/25 networks are not successful. What could explain this connectivity problem?

A.The RIP v2 dynamic routing protocol cannot be used across a Frame Relay network .
B.The ip subnet-zero command has been is sued on the R1 router.
C.Split horizon is prevneting R2 from learning about the R3 network and R3 from learning about the R2 networks.
D.The 172.16.3.0/29 network used on the Frame Relay links is creating a discntiguous network between the R2 and R3 router subnetworks.
E.The 172.16.2.0/25 and 172.16.2.128/25 networks are overlapping net works that can be seen by R1,but not between R2 and R3.,

Answer :C

E. Connect another router to a serial interface of R1. Use a FastEthernet interface on the new router for VLAN3.

Answer: D

Question:427
How is an EUI-64 format interface ID created from a 48-bit MAC address?
