QUESTION 239
router bgp 1
neighbor 1.1.1.1 remote-as 2
The above bgp configuration has what effect on the configured router?

B. Allows incoming TCP connections from 1.1.1.1 that are destined to port 179
C. Allows incoming TCP connections sourced from port 179
D. Allows incoming TCP connections from 1.1.1.1 and destined to or sourced from port 179

Answer: B
QUESTION 240
In an OSPF domain, four routers have OSPF neighborship over a broadcast domain. What is the expected state after running the show ip OSPF neighbor commandon the OSPF designated router?
A. one FULL state, two 2WAY states
B. two FULL states, one 2WAY state
C. three FULL states
D. three 2WAY states
Answer: C
QUESTION 241
Refer to the exhibit. A company is deploying IPv6 using a dual-stack approach. OSPFv2 is used for IPv4 routing and is redistributed into the BGP IPv4 address family.The network engineer also
needs to enable OSPFv3 for IPv6 routing using the same design that is used for OSPFv2. All prefixes in the OSPFv3 database must be redistributed into the BGP IPv6 address family at router R2, but R3 does not receive the loopback0 IPv6 address of R2 via BGP.
Which action will fix this problem?
A. redistribution of BGP routes into OSPFv3
B. redistribution of OSPFv3 routes into BGP with include-connected
C. mutual redistribution of OSPFv3 and BGP routes
D. redistribution of connected OSPFv3 routes
Answer: B
QUESTION 242
A customer requests that sites are connected over an MPLS backbone using the MPLS AToM service. However, the network engineer advises that the MPLS L3VPN service may bebetter for this situation. Which characteristic of MPLS L3VPN may make it a better option from the Service Provider perspective?
A. Reduction of operational complexity.
B. Support for multiple network layer protocols, such as IP, IPX, and SNA
C. CustomerLayer 2 information will be maintained over the service provider core.
D. Transparent to the customer
Answer: A
QUESTION 243
Refer to the exhibit. RIP network 192.168.1.0/24 is redistributed in OSPF Area 1; both Area 1 and Area 2 are configured as NSSAs.
Which three statements describe the OSPF behavior in this scenario? (Choose three.)
A. Area 2 does not see the network 192.168.1.0/24 in itslink-state database.
B. Network 192.168.1.0/24 is advertised in a Type 7 LSA in Area 1.
C. Network 192.168.1.0/24 is advertised in a Type 5 LSA in Area 0.
D. Network 192.168.1.0/24 is advertised in a Type 7 LSA in Area 0.
E. ABR between Area 0 and Area 2 converts network 192.168.1.0/24 to a Type 7 LSA.
F. Network 192.168.1.0/24 is advertised in a Type 5 LSA in Area 2.
Answer: ABC
QUESTION 244
A network engineer wants to deploy a VPLS service within the MPLS backbone. The backbone expert team advises that LDP for signaling is used.
Which two characteristics of LDP would influence their decision? (Choose two.)
A. BGP does not need to be run on the PE device.
B. Non-convergence with IP VPN operation.
C. There is no autodiscovery.
D. LDP signaling requires a loopback-based router ID.
E. CDP is not required on the PE routers.
Answer: AC
QUESTION 245
A network engineer is using IS-IS IGP protocol to design a network.
Which three design elements should beused to divide the network into a hierarchy of areas? (Choose three.)
A. Core routers will be only level-2.
B. Routers on the edge of the network will be only level-1.
C. Router between core and edge routers will be level-1-2.
D. Core routers will be onlylevel-1.
E. Routers on the edge of the network will be only level-2.
F. Router between core and edge routers will be only level-2.
G. Router between core and edge routers will be only level-1.
Answer: ABC
QUESTION 246
Refer to the exhibit. A service provider is using the configuration to determine traffic paths based on MPLS EXP markings. Which technology is being implemented?
A. MPLS TE FRR
B. CBTS
C. IP FRR
D. MPLS TE
E. PBTS
F. DS-TE
Answer: B
QUESTION 247
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
QUESTION 248
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)
