1.Refer to the exhibit. R1 and R2 belong to the RIP routing domain that includes the networks 10.20.0.0/16 and 10.21.0.0/16. R3 and R4 are performing two-way route redistribution between OSPF and RIP. A network administrator has discovered that R2 is receiving OSPF routes for the networks 10.20.0.0/16 and 10.21.0.0/16 and a routing loop has occurred.Which action will correct this problem?
A: Apply an inbound ACL to the R2 serial interface.
B: Change the RIP administrative distance on R3 to 110.
C: Configure distribute-lists on R3 and R4.
D: Set the OSPF default metric to 20.E: Change the OSPF administrative distance on R3 to 110.
Correct Answers: C

2.The original frame is encapsulated and an additional header is added before the frame is carried over a trunk link. At the receiving end, the header is removed and the frame is forwarded to the assigned VLAN. This describes which technology?
A: DISL
B: DTP
C: IEEE 802.1Q
D: ISLE: MPLS
Correct Answers: D
?
3.Refer to the exhibit. What is the effect of the distribute-list command in the R1 configuration?
A: R1 will filter only the 172.24.1.0/24 route from the R2 RIP updates.
B: R1 will permit only the 10.0.0.0/24 route in the R2 RIP updates.642-444
C: R1 will filter the 10.1.0.0/24 and the 172.24.1.0/24 routes from the R2 RIP updates.
D: R1 will not filter any routes because there is no exact prefix match.
Correct Answers: C

4.Refer to the exhibit. Routers RTA and RTB are running BGP but the session is active. What command needs to be added to establish the BGP session?
A: ip route 10.10.10.1 255.255.255.255 s0/0ip route 10.10.10.1 255.255.255.255 s0/1
B: network 10.10.10.0
C: neighbor 10.10.10.1 next-hop-self 642-892
D: no synchronization
Correct Answers: A

5.Given the network configuration above and assuming that STP is enabled, which port will be elected the non-designated port?
A: Port 1/1
B: Port 1/2
C: Port 2/1
D: Port 2/2E: Port 3/1F: Port 3/2
Correct Answers: B
?
6.On a 3550 EMI switch, which three types of interfaces can be used to configure HSRP? (Choose three.)
A:loopback interface
B:SVI interface
C:routed port
D:access portE:EtherChannel port channelF:BVI interface
Correct Answers: B, C, E
?
7.Which three characteristics apply to IS-IS but not to OSPF? (Choose three.)
A:encapsulates PDUs directly into a data-link frame
B:uses a DIS and a backup DIS to present the psuedo-node on the LAN
C:uses stubby areas to improve network scalability
D:uses a default IOS metric of 10 on each interface
E:runs PRC (Partial Route Calculations) to calculate IP reachability informationF:uses an on-demand circuit to reduce the hello and LSA flooding across switched WAN links, such as ISDN
Correct Answers: A, D, E
?
8.Which two statements are true about IBGP neighbor relationships? (Choose two.)
A:An EGP or static routing is required between IBGP neighbors. ?
B:A full-mesh IBGP requires that neighbor relationships be established between all BGP enabled routers in the autonomous system.
C:IBGP neighbors must be in different autonomous systems.
D:The BGP split-horizon rule specifies that routes learned via EBGP are never propagated to other IBGP peers.
E:The BGP split horizon rule specifies that routes learned via IBGP are never propagated to other IBGP peers.
Correct Answers: B, E
