• Question 561:

  A service provider is implementing an nV Edge system with the two ASR 9000 chassis has two RSPs. Which two cabling methods reflect the minimum configuration needed for full synchronization between the two Cisco ASR 9000 chassis? (Choose two)

  A. Create the single virtual control plane that connect the two RSPs between the two chassis via Layer 2 connections
  B. Create the IRL connections between the two chassis via Layer 3 connections using the EOBC 10 Gbps ports of the RSPs
  C. Create the IRL connections between the two chassis via Layer 3 connections using the ports of the line cards
  D. Create the single virtual control plane that connect the two chassis via Layer 3 connections using the 10 Gbps ports of the line cards
  E. Create the IRL connections between the two chassis via Layer 1 connections using the10 Gbps ports of the line cards
  F. Create the single virtual control plane that connect the two chassis via 100 Gbps bundle interfaces
  G. Create the IRL connections between the two chassis via Layer 1 connections using the EOBC 10 Gbps ports of the RSPs
  A. Create the single virtual control plane that connect the two RSPs between the two chassis via Layer 2 connections
  E. Create the IRL connections between the two chassis via Layer 1 connections using the10 Gbps ports of the line cards

• Question 562:

  Which IEEE task group provides a method to implement QoS on an Ethernet level?

  A. 802.1ab
  B. 802.1p
  C. 802.1q
  D. 802.1s
  E. 802.1w
  B. 802.1p

• Question 563:

  What are the differences between LLQ and CBWFQ? (Choose two.)

  A. LLQ priority queue bandwidth is policed with a congestion aware policer.
  B. With LLQ, bandwidth allocations for the priority queue and all the CBWFQ queues are configured using the priority command.
  C. LLQ does not support WFQ on the default traffic class (class-default).
  D. LLQ supports the addition of strict priority queuing.
  E. LLQ is configured using MQC and CBWFQ is configured using the fair-queue command.
  A. LLQ priority queue bandwidth is policed with a congestion aware policer.
  D. LLQ supports the addition of strict priority queuing.

• Question 564:

  What is the purpose of Route Target Constraint?

  A. A new Route Target definition is specified in RFC 4684. The Syntax differs from old syntax. The old syntax is a waste of processing power on the Route Reflector and PE and is waste of bandwidth.
  B. Route Targets are not attached to the VPNv4 or VPNv6 prefixes. Instead of using route targets, Route Distinguishers used to import and export VPNv4 and VPNv6 prefixes to and from VRFs.
  C. Route Reflectors send only wanted VPNv4 or VPNv6 prefixes. "Wanted" means the PE has VRF importing the specific prefixes.
  D. The Route Targets are constrained to one Autonomous System. The ASBR router strip all of the Route Target information that is contained in the VPNv4 or VPNv6 prefixes.
  C. Route Reflectors send only wanted VPNv4 or VPNv6 prefixes. "Wanted" means the PE has VRF importing the specific prefixes.

• Question 565:

  What is the proper MP-BGP configuration between the shown PE routers to implement MPLS VPNs on PER2?

  

  A. None of the above
  B. router bgp 1 neighbor 50.0.0.4 remote-as 1 neighbor 50.0.0.4 update-source Loopback0 no auto-summary ! address-family ipv4 neighbor 50.0.0.4 activate neighbor 50.0.0.4 send-community extended exit-address-family
  C. router bgp 1 neighbor 50.0.0.4 remote-as 1 neighbor 50.0.0.4 update-source Loopback0 no auto-summary ! address-family vpnv4 neighbor 50.0.0.4 activate neighbor 50.0.0.4 send-community extended exit-address-family
  D. router bgp 1 neighbor 50.0.0.4 remote-as 1 neighbor 50.0.0.4 update-source Loopback0 no auto-summary ! address-family vpnv4 unicast multicast neighbor 50.0.0.4 activate neighbor 50.0.0.4 send-community extended exit-address-family
  C. router bgp 1 neighbor 50.0.0.4 remote-as 1 neighbor 50.0.0.4 update-source Loopback0 no auto-summary ! address-family vpnv4 neighbor 50.0.0.4 activate neighbor 50.0.0.4 send-community extended exit-address-family

• Question 566:

  Which statement about Policy-Based Tunnel Selection implementation on Cisco CRS Series is true?

  A. Load balancing across multiple MPLS TE tunnels is not supported.
  B. IGP and LDP are the default path for traffic that do not meet any of the classification criteria.
  C. Classification criteria of the incoming packets can be based on IP precedence, EXP, or TOS field in the packet.
  D. PBTS is activate only when policy-based routing is applied.
  C. Classification criteria of the incoming packets can be based on IP precedence, EXP, or TOS field in the packet.

• Question 567:

  A network administrator wants to detect a login attack against a router. What IOS command can make the attack recorded in syslog server?

  A. Login detect login-failure log
  B. none of the above
  C. Logging detect fail-login
  D. Login on-failure log
  E. Logging login on-failure
  D. Login on-failure log

• Question 568:

  A service provider engineering team must design a solution that supports end-to-end LSPS for multiple IGP domains within different AS numbers. According to RFC 3107, which solution achieves this goal?

  A. LDP and BGP
  B. BGP and Send-label
  C. RSVP and IS-IS or OSPF
  D. RSVP and BGP
  E. mLDP
  B. BGP and Send-label

  Select and Place:

  

  

• Question 570:

  

  Refer to the exhibit. Customer Y reported that internet traffic stopped for a few minute. The ISP ABC operation engineer identified that this occurred when ASBR1 router reloaded OSPF coverage faster than BGP. Which command prevent this happening?

  A. Graceful restart
  B. set-overload-bit on startup wait-for-bgp
  C. bfd min_rx 100 max_rx 100 multiplier 3
