A non-client is an IBGP peer that functions as neither an RR nor a client. A non-client must establish fully meshed connections with the RR and all the other non-clients.
Correct Answer: A
Non-Client Definition in IBGP * In an IBGP setup with a Route Reflector (RR), a non-client is an IBGP peer that is neither the RR itself nor its client. * Non-clients must establish fully meshed IBGP connections with all other non-clients and the RR because IBGP rules prohibit route propagation between non-clients without a direct connection. HCIP-Datacom-Core Reference * The behavior of non-clients in an RR topology is clearly outlined in the BGP implementation chapters.
Question 47
Which of the following statements regarding the MED value in BGP are true?
Correct Answer: A,D
The MED (Multi-Exit Discriminator) is an optional, non-transitive attribute used to influence the exit path. MED is considered after attributes such as Local-Preference, AS-Path, and Origin during route selection. By default, if a MED value is missing, it is treated as 0 unless the bestroute med-none-as-maximum command is configured to treat it as 4294967295 .
Question 48
On an OSPF network, one router with P2P as the network type is directly connected to another router with P2MP as the network type. If the Hello intervals on the two routers are changed to be the same, neighbor relationship establishment and LSDB synchronization are not affected.
Correct Answer: B
The scenario describes a mismatch in OSPF network types between two connected routers: one set to Point-to- Point (P2P) and the other set to Point-to-Multipoint (P2MP). While aligning Hello intervals may seem sufficient for establishing an OSPF neighbor relationship, the fundamental mismatch in network types introduces issues. * OSPF Network Types * P2P: Assumes a direct connection with a single neighbor, uses faster convergence and simpler LSDB synchronization. * P2MP: Supports multiple neighbors on a single interface, requiring different handling for DR /BDR roles and LSDB updates. * Impact of Network Type Mismatch * If Hello intervals are aligned, adjacency establishment might occur. However, mismatched network types affect neighbor role assignment and LSDB synchronization. * P2P expects a direct link and would handle updates differently than P2MP, which assumes multiple neighbors. This leads to inconsistencies in route calculation and forwarding. * HCIP-Datacom-Core Reference * OSPF Basics and Configurationclearly outlines the criticality of consistent network type configuration for stable OSPF operation. * Lab examples in the HCIP Datacom Lab Guidefurther demonstrate the consequences of such mismatches, including unstable neighbor states and incomplete LSDB synchronization. Hence, the statement that neighbor relationships and LSDB synchronization remain unaffected is incorrect. Proper OSPF operation requires matching network types in addition to aligned Hello intervals.
Question 49
Compress the 2001:0DBB:B8:0000:C030:0000:0000:09A0:CDEF address.___________(if the answer contains letters, capitalize them.)
Correct Answer:
pending
Question 50
Which of the following statement regarding the display ospf peer command output is true?
Correct Answer: B
The command output indicates that the OSPF neighbor state is Full and that the neighbor relationship has been established. The statement confirms that the negotiation process during the exchange of DD (Database Description) packets has determined the role of the router, with the local device becoming the slave in the Master-Slave relationship, which is critical for LSA synchronization. The other options do not align with the output or OSPF principles
