New Question
In Multicast VPN (MVPN) implementations, which two of the following statements are regarding the Default MDT Group? (Choose two).
A. It is used for PIM control traffic.
B. It is optionally configured for a high bandwidth multicast source to reduce multicast traffic replication to uninterested PE routers.
C. Within the VRF configuration in the PE router, multiple Default MDT groups are configured so each VRF can support multiple multicast sources.
D. There is a reduced multicast state in the MPLS core P routers.
E. When multicast traffic exceeds a certain configured threshold, traffic from the Data MDT is switched to the Default MDT to conserve bandwidth.
Answer: AD
New Question
In relation to MPLS Multicast VPN, which three statements about multicast distribution (MDT) groups are true? (Choose three)
A. Default MDT groups are used for PIM control traffic, low-bandwidth sources, and flooding of sparse mode traffic.
B. MDTs are built in customer networks
C. Data MDT groups are used for high-bandwidth sources to reduce replication to uninterested PEs.
D. MDTs are built in provider networks
E. The number of MDTs depends on PIM modes of MDT groups.
Answer: CDE
New Question
Which statement about multicast VPN is true?
A. The MDT group address should be the same for both address families in the same VRF.
B. The MDT group address should be the same for both address families in the different VRFs.
C. Configuration of the MDT source on a pre-VRF basis is supported only on IPv6.
D. The MDT group address should be different for both address families in the same VRF.
Answer: A
New Question
Which statement about the use of Route Target Rewrite is true?
A. It is mainly used in Intra-AS MPLS VPN deployments and is configured at the ASBR to avoid misconfiguration of the Route Target assignment for VPN configurations.
B. It is mainly used in Inter-AS MPLS VPN deployments and is configured at the ASBR to avoid misconfiguration of the Route Target assignment for VPN configurations.
C. It is mainly used in Intra-AS MPLS VPN deployments and is configured at the Router Reflector to avoid misconfiguration in Route Target assignment for VPN configurations
D. It is mainly used in Inter-AS MPLS VPN deployments and is configured at the Router Reflector to avoid misconfiguration of the Route Target assignment for VPN configurations
E. It is mainly used in Inter-AS MPLS VPN deployments and is configured at the PE router to avoid to misconfiguration of the Route Target assignment for VPN configurations
Answer: B
New Question
Which statements about the Route Target Rewrite feature are not true? (Choose two.)
A. After the route target replacement policy is applied to the target router, the BGP session need not be refreshed manually to put the policy into operation.
B. Route Target Rewrite allows the administration of the routing policy to stay local to the AS.
C. Route target replacement is always done by the ASBR.
D. Route target rewrites are supported for VRF export maps.
E. Route target replacement can be done on incoming and outgoing BGP updates.
Answer: AC
New Question
Which statement about implementing the Cisco IPv6 provider Edge Router over MPLS is true?
A. 6PE feature is supported over tunnels other than RSVP-TE tunnels.
B. Core MPLS routers are supporting IPv6 only.
C. 6PE feature is not supported over tunnels other than RSVP-TE tunnels.
D. Core MPLS routers are supporting IPv4 only.
Answer: C
New Question
Assume that the PEs are separated by Multiple P routers. How many labels should the ingress PE push for 6PE functionality?
A. 1
B. None
C. 3
D. 2
E. It depends on the numbers of hops between the ingress and egress PE.
Answer: D
Explanation:
A PE device on receiving the IPv6 prefix from CE by routing protocol will assign a label and advertise through BGP to other PE devices which in turn will be advertised to remote CE devices. This label information will be used to switch the packet through MPLS cloud. 6PE implementation will have minimum 2 labels imposed, top label being the one to identify the remote PE while bottom label to identify the IPv6 prefix.
New Question
Which option describes a benefits of IPv6 VPN Provider Edge?
A. Provider support for intra-AS and CSC scenarios
B. Uses separate signaling plane, which provides more security than IPv4
C. BGP is the preferred routing protocol for connecting two SPs.
D. No requirement for a separate signaling plane
Answer: D
New Question
Which two statements about VPNv4 address are true? (Choose two.)
A. The VPNv4 address is 128 bits long with a 128-bit long subnet mask
B. The VPNv4 address consists of an RD and an IPv4 address.
C. The VPNv4 address is 96 bits long with a 64-bit long subnet mask.
D. The VPNv4 address is 128 bits long with a 64-bit long subnet mask.
E. The VPNv4 address consists of an RT and an IPv4 address.
F. The VPNv4 address is 96 bits long with a 32-bit long subnet mask
Answer: BF
New Question
Which two statements about Layer 3 MPLS VPN are true? (Choose two.)
A. The virtual routing and forwarding table is separate from the global routing table that exists on PE routers.
Routes are injected into the VRF from the CE-PE routing protocols for that VRF and any MP-BGP announcements that match the defined VRF RTs.
B. Multiprotocol Border Gateway Protocol is run between PE and CE routers to exchange customer prefixes in a VPNv4 format.
C. A customer edge router peers at Layer 3 to the provider edge. The PE-CE interface runs either a dynamic routing protocol (eBGP, RIPv2, EIGRP, OSPF) or a static routing protocol (Static, Connected).
D. VPNv4 address is the combination of the RT and customer IPv4 prefix. These VPNv4 prefixes are passed in MP-BGP.
Answer: AC
New Question
Which Cisco IOS command displays the export VPN route target value of a VRF?
A. show ip vrf all
B. show ip vrf route-targets all
C. show ip vrf summary
D. show ip vrf interfaces
E. show ip vrf detail
F. show ip vrf
Answer: E
