NEW QUESTION # 233
Refer to the exhibit. An enterprise uses dual-homed MPLS connectivity for critical branch locations and single-homed MPLS connectivity for smaller, less essential branch sites. Against the enterprise security policy, Branch A experiences traffic flow from Branch B toward HQ when the MPLS2 network fails. Which technique resolves this issue?
Answer: A
Explanation:
A BGP as-path filter on Branch A that only advertises its own locally originated prefixes prevents Branch A from becoming a transit path for Branch B's traffic to HQ during MPLS2 failure. This enforces policy and eliminates the undesired traffic flow.
NEW QUESTION # 234
A network administrator is troubleshooting a DMVPN setup between the hub and the spoke.
Which action should the administrator take before troubleshooting the IPsec configuration?
Answer: C
NEW QUESTION # 235
In a multicast network, which condition must be met for an RPF check to be performed on the RP address'?
Answer: A
NEW QUESTION # 236
An ISP provides Layer 3 VPN service over MPLS to a customer with four branches and multiple CE routers at each branch. To exchange the routes that are learned from the CE routers, which BGP address family should the ISP activate among the PE routers?
Answer: B
Explanation:
The provider must activate the VPNv4 unicast address family between PE routers. In an MPLS Layer 3 VPN, customer routes learned from CE routers are placed into VRFs on the PE routers. To carry those customer routes across the provider backbone without overlap, MP-BGP advertises VPNv4 routes, which combine an IPv4 prefix with a route distinguisher. Route targets then control which receiving VRFs import the routes.
Plain IPv4 unicast would not preserve customer VPN context and would not solve overlapping route separation. L2VPN EVPN is used for Ethernet VPN services and data center or Layer 2 VPN use cases, not classic MPLS L3VPN route exchange between PEs. Address-family multicast is unrelated to exchanging customer unicast routes between PE routers. Cisco MPLS VPN design relies on MP-BGP VPNv4 between provider edge routers, while PE-CE routing can be static, OSPF, EIGRP, BGP, or another supported method.
Therefore, VPNv4 unicast is the correct PE-to-PE address family. Reference topics: MPLS Layer 3 VPN, MP- BGP, VPNv4 unicast, route distinguishers, route targets, PE-CE routing.
NEW QUESTION # 237
In PIM sparse mode, if an RPF check is successful on a multicast-enabled device, what happens to the multicast packet?
Answer: A
Explanation:
In PIM sparse mode, when a multicast-enabled device performs a Reverse Path Forwarding (RPF) check and it is successful, the multicast packet is forwarded to all interfaces listed in the Outgoing Interface List (OIL). The OIL contains the set of interfaces where the multicast packet should be sent to reach the interested receivers. This ensures efficient and loop-free multicast traffic delivery.
