A service provider is running a single area OSPFv2 instance in the MPLS network. The OSPF re-convergence time is becoming excessively slow as the service provider MPLS network grows. Which two action can improve network performance without implementing a multi area design? (Choose two).
A. Configure incremental SFP
B. Reduce type 5 LSAs
C. Implement Partial Route Computation
D. Limit number of TVLs
E. Enable LSA group pacing
Correct Answer: A,E
A content provider uses ISP-A and ISP-B for internet transit service for the purpose of redundancy and load balancing. The content provider has address range assigned to it. 400-201 pdf
Which two techniques achieve the load balancing and redundancy for inbound traffic? (Choose Two)
A. Use ISP-A for outbound traffic and ISP-B for inbound traffic.
B. Aggregate all prefixes received from both ISPs into a less-specific prefix.
C. BGP MED attribute.
D. Address range split into two more specific prefixes, then advertise one specific prefix per ISP.
E. BGP AS-prepend technique
F. BGP Local Preference attribute.
Correct Answer: C,E
Refer to the exhibit. The Service Provider does not have IPv6 support in the core, however it does have MPLS support. Customer requires IPv6 connectivity in all sites including Internet access. 400-201 dumps Without a requirement to create VRF, which method is preferred to support IPv6 traffic between these sites?
Correct Answer: F
In MPLS-enabled network, 400-201 dumps which two improvements does EVPN provide compared to traditional VPLS?
A. Use of LDP to allocate EVPN-related labels
B. Per flow load balancing
C. Optimized learning and flooding process
D. Leveraging of enhanced VFIs to provide greater scalability
E. No need for exchange of MAC reachability between PEs
F. Use of BGP as a control-plane protocol
Correct Answer: B,C
In a virtualization concept, which is one of the characteristic of the HVR solution?
A. introduces significant contention of resources
B. implements shared control plane resources
C. implements dedicated chassis resources
D. implements dedicated data plane resources
Correct Answer: D
Two OSPF neighborrouters are stuck in the EXSTART state. After a while, the neighborship goes down. A network engineer is debugging the issue when both routers show the OSPF log message “too many retransmissions.” What is the possible root cause?
A. OSPF area mismatch
B. OSPF hello-interval mismatch
C. interface MTU mismatch
D. interface network type mismatch
Correct Answer: C
A Service Provider wants to extend MPLS WAN endpoints in the cloud at the edge of a customer network within the cloud. Which platform will meet this requirement? 400-201 pdf

Correct Answer: B
Which information is carried in the OSPFv3 intra-area Prefix LSA?
A. All link-local addresses
B. All IPv6 prefix and topology information that OSPFv2 included in Router LSA and Network LSA
C. List of options associated with the link to all other routers attached to the link
D. All prefix-specific information that OSPFv2 included in Router LSA and Network LSA
Correct Answer: D
An engineer is deploying SSHv2 only in band access. 400-201 dumps Which three options reflect the minimum configuration to enable the SSHv2 services on Cisco routers? (Choose three)
A. Add router hostname on DNS services.
B. Define a hostname for the device.
C. Define a domain name for the device.
D. Create an access list that defines authorized hosts for SSH.
E. Create crypto keys by using the crypto key generate dsa command.
F. Configure a key modulus in the global configuration.
Correct Answer: B,C,E
Which two statements about the bgp deterministic-med and bgp always-compare-med commands are true? (Choose two)
A. The bgp deterministic-med command is used to influence the BGP route selection process to cause the MED attribute to have higher precedence over the AS path length.
B. The bgp always-compare command is used to influence the BGP route selection process to cause the MED attribute to have higher precedence over the AS path system.
C. Enabling the bgp deterministic-med command ensures the comparison of the MED variable when choosing routes advertised by different peers in the same autonomous system.
D. Enabling the bgp always-compare-med command ensures the comparison of the MED variable for paths from neighbors in different autonomous systems.
E. The bgp deterministic-med and bgp always-compare-med commands are enabled by defult.
Correct Answer: C,D
