A. It dictates the import and export policies for the local VRF routing table.
B. It ensures that overlapping IP prefixes from different customers remain unique within the provider’s BGP core.
C. It determines the inner MPLS service label that is pushed onto the customer payload.
D. It prevents routing loops when acting as a Route Reflector in a hub-and-spoke topology.
Answer:<\/strong> B
Explanation:<\/strong>
RDs are pre-pended to IPv4\/IPv6 addresses to create VPN-IPv4\/VPN-IPv6 addresses, making non-unique customer IP prefixes globally unique within the MP-BGP core. Route Targets (RTs) handle the import\/export policies (Option A).<\/p>\n\n\n\n
A. Administrative groups (Color\/Affinities)
B. Hop count limits
C. Available link bandwidth
D. LDP synchronization state
Answer:<\/strong> D
Explanation:<\/strong>
CSPF dynamically calculates paths across the TE topology database based on metrics like Bandwidth, Admin Groups (Colors), Hop Limits, and TE metrics. LDP synchronization is a local IGP interaction and is not a constraint evaluated by the CSPF algorithm.<\/p>\n\n\n\n
A. By modifying the NEXT_HOP attribute to its own System IP address.
B. By utilizing the ORIGINATOR_ID and CLUSTER_LIST attributes.
C. By appending its own Autonomous System number to the AS_PATH attribute.
D. By setting the LOCAL_PREF attribute to zero for all reflected routes.
Answer:<\/strong> B
Explanation:<\/strong>
Route Reflectors use two specific BGP attributes for loop prevention within an AS: ORIGINATOR_ID (the Router ID of the router that originated the route into the local AS) and CLUSTER_LIST (a list of RR cluster IDs the route has passed through).<\/p>\n\n\n\n
A. Q-in-Q (qinq)
B. GRE (Generic Routing Encapsulation)
C. Null
D. IPsec
Answer:<\/strong> A, C
Explanation:<\/strong>
On SR OS, null, dot1q, and qinq are the standard Ethernet port encapsulations used to define how SAPs accept traffic. GRE and IPsec are tunnel protocols or SDP types, not physical port encapsulations for SAPs.<\/p>\n\n\n\n
A. It translates the Level 1 LSP into a Level 2 LSP and floods it to the Level 2 backbone.
B. It floods the Level 1 LSP only within the local Level 1 area.
C. It forwards the LSP directly to the designated Level 2 Route Reflector.
D. It drops the LSP silently if the Attached (ATT) bit is not set.
Answer:<\/strong> B
Explanation:<\/strong>
In IS-IS, Level 1 LSPs are restricted to the local L1 area database. While an L1\/L2 router will inject L1 routing information into the L2 backbone as leaf prefixes (route leaking), it does NOT flood the actual L1 LSP into the L2 area.<\/p>\n\n\n\nKey Benefits of Using 4A0-C03 Practice Tests for Exam Success<\/h2>\n\n\n\n
