Q1. Refer to the exhibit.
All routers have OSPF adjacency with the directly connected routers, yet RC cannot receive OSPF updates from Area 0 To fix this issue, which configuration should be applied?
A. On RD router
router ospf 1
area 1 virtual-link 3.3.3.3
On RB router:
router ospf 1
area 1 virtual-link 4.4.4.4
B. On RC router.
router ospf 1
area 2 virtual-link 3.3.3.3
On RB router:
router ospf 1
area 2 virtual-link 2.2.2.2
C. On RC router
router ospf 1
area 0 virtual-link 1.1.1.1
On RA router:
router ospf 1
area 2 virtual-link 2.2.2.2
D. On RD router:
router ospf 1.
area 1 virtual-link 1.1.1.1
On RA router:
router ospf 1 areal virtual-link 4.4.4.4
Answer: A
Q2. Refer to the exhibit. The configuration in the exhibit redistributes static route 172.16.0.0/24 into BGP. Which action does the route-map STATIC-TO-BGP do?
A. Route 172.16.0.0/24 cannot be sent to the Internet.
B. Route 172.16.0.0/24 cannot be re-advertised beyond its neighbors.
C. Route 172.16.0.0/24 cannot be advertised outside of AS 100.
D. Route 172.16.0.0/24 cannot be exported from BGP to another protocol.
Answer: C
Q3. A service provider is implementing Ethernet solutions for clients that are not being provisioned within the MPLS core network. Which solution allows the Service Provider to complete Ethernet circuit provisioning in this scenario?
A. L2TPv3
B. VPLS
C. AToM
D. PPPoE
Answer: A
Explanation:
L2TPv3 defines the L2TP protocol for tunneling Layer 2 payloads over an IP core network using Layer 2 virtual private networks (VPNs). Benefits of this feature include the following:
. Simplifies deployment of VPNs.
. Does not require Multiprotocol Label Switching (MPLS) virtual private network (VPN).
. Supports Layer 2 tunneling over IP for any payload.
. Supports data encapsulation directly over IP (IP protocol number 115), not using User Datagram Protocol (UDP) .
Supports point-to-point sessions, not point-to-multipoint or multipoint-to-point sessions .
Supports sessions between the same Layer 2 protocols, for example Frame Relay-to-Frame Relay or ATM-to-ATM.
Q4. Refer to the exhibit. R3 cannot install a route to R1-R2 subnet 2001:1:155:12::/64. Which action resolves this issue?
A. Add the redistribute ospf 1 include-connected command under the ipv6 router eigrp 10 process.
B. For the OSPF process, add the no shutdown command.
C. For prefix-list OSPF_INTO_EIGRP seq 20, replace the prefix with 2001:155:1:12::/64.
D. For route-map OSPF_INTO_EIGRP, add the set metric 1000 1 255 1 1500 command.

Q5. Based on the following configuration:
Which two statements about multicast VPN configuration are true? (Choose two.)
A. The multicast tree is created based only on the existence of active sources or receivers behind PEs in the ABC VRF.
B. The service provider core network is required to support SSM.
C. Multicast needs to be enabled only on ABC VRF and is tunneled to participating PE routers in the ABC VRF.
D. The SP core network is required in order to enable the BGP Multicast Address Family on all peering.
E. Multicast is required for the core network in addition to the ABC VRF.
F. The multicast tree exists regardless of whether there are any active sources or receivers in the ABC VRF.
Answer: E,F

Q7. An engineer is troubleshooting Precision Time Protocol on Cisco ASR 9000 router and noticed the protocol is running in a Multicast mode. Which two results regarding the messages can the engineer expect? (Choose two)
A. IPTP messages that use unicast messages and those that use multicast messages must be specified.
B. Announce and Sync messages are sent as multicast messages.
C. Signaling. Delay-Request and Delay-Response messages are sent as multicast messages
D. All messages for PTP will be sent as multicast messages
E. Announce and Sync messages are sent as unicast messages
F. Signaling, Delay-Request, and Delay-Response messages are sent as unicast messages
Answer: B,F
Q8. Two switches are connected back-to-back using two Gigabit Ethernet interfaces. These two interfaces are assigned to a port channel in VLAN trunk mode. Which configuration sequence allows the addition of a new VLAN in this link?
A. Add the VLAN to the port channel only, and remove it from the individual links.
B. Add the VLAN to both the port channel and individual links.
C. Add the VLW to the port channel only, and it will be reflected on the individual links.
D. Add the VLAN to the individual links, and it will be reflected on the port channel.
Answer: C
