  Correct Answer: A

• Question 123:

  Refer to the exhibit.

  

  A large service provider is migrating device management from Layer 2 VLAN-based to Layer 3 IP-based solution. An engineer must configure the ISIS solution with these requirements:

  1.

  Network management server IP 172.16.10.1 must be advertised from the core MPLS network to the regional domain.

  2.

  The external network 202.10.0.0/24 must not establish ISIS peering with the R5 router.

  3.

  The regional network must prevent sending unnecessary hello packets and flooding the routing tables of the R5 router.

  Which two ISIS parameters must be implemented to meet these requirements? (Choose two.)

  A. LSP lifetime maximum

  B. advertise-passive-only

  C. overload bit passive

  D. attached bit on ISIS instance

  E. passive-interface Loopback0

  Correct Answer: AD

• Question 124:

  What is a characteristic of data modeling language?

  A. It provides an interface for state data.

  B. It separates configuration and state data.

  C. It ensures devices are individually configured.

  D. It replaces SNMP.

  Correct Answer: B

• Question 125:

  FRR is configured on a network. What occurs when the headend router on the path is alerted to a link failure over IGP?

  A. LSP attempts fast switching on the backup path until the primary path returns to the active state.

  B. The headend router uses a presignaled LSP to bypass the failure point.

  C. A new backup tunnel is established past the PLR to pass through the protected nodes.

  D. Backup tunnel is established and intersects with the primary tunnel at the headend.

  Correct Answer: A

• Question 126:

  How does Inter-AS Option-A function when two PE routers in different autonomous systems are directly connected?

  A. The two routers share all Inter-AS VPNv4 routes and redistribute routes within an IBGP session to provide end-to-end reach.

  B. The two routers establish an MP-EBGP session to share their customers' respective VPNv4 routes.

  C. The two routers treat one another as CE routers and advertise unlabeled IPv4 routes through an EBGP session.

  D. The two routers share VPNv4 routes over a multihop EBGP session and set up an Inter-AS tunnel using one another's label.

  Correct Answer: C

• Question 127:

  Refer to the exhibit.

  

  An engineer at ISP C is configuring a new interconnection with ISPs A and B using the BGP protocol. After the initial configuration, the engineer noticed high memory usage and an abnormally large LIB table on router R2. Which two actions must the engineer take on R2 to minimize memory usage? (Choose two.)

  A. Configure the mpls ldp neighbor 11.11.11.11 labels accept 1 command.

  B. Configure Standard ACL 1 with accepted prefixes.

  C. Configure Extended ACL 101 with accepted prefixes.

  D. Configure the mpls ldp neighbor 1.1.1.1 labels accept 101 command.

  E. Configure the mpls ldp neighbor 21.21.21.21 labels accept 101 command.

  Correct Answer: AB

• Question 128:

  Refer to the exhibit.

  

  The application server in the data center hosts voice, video, and data applications over the internet. The data applications run more slowly than the voice and video applications. To ensure that all applications run smoothly, the service provider decided to implement a QoS policy on router PER 2 to apply traffic shaping. Which two actions must an engineer take to implement the task? (Choose two.)

  A. Configure the scheduling function to handle delayed packets.

  B. Enable packet remarking for priority traffic.

  C. Configure a queue to buffer excess traffic.

  D. Set the token value for secondary traffic.

  E. Set a threshold to discard excess traffic.

  Correct Answer: A

• Question 129:

  Refer to the exhibit.

  

  The link between Office A and Office B is running at 90% load, and occasionally the CPU on router R1 is overloaded. The company implemented QoS for business-critical applications at both offices as a temporary solution. A network engineer must update the R1 configuration to 600 ms to reduce CPU load and limit downtime after connection failure to avoid data loss. Which action meets this requirement?

  A. Configure the fast-hello feature for OSPF with the command ip ospf dead-interval minimal hello-multiplier 3.

  B. Configure BFD demand mode with the command bfd-demand timer 150 interval 250 retransmit 5.

  C. Configure BFD non-echo mode with the command echo interval 250 minimal 300 echo-multiplier 2.

  D. Configure BFD echo mode with the command bfd interval 150 min_rx 200 multiplier 3.

  Correct Answer: D

• Question 130:

  Refer to the exhibit.

  

  A network engineer is configuring a new router for iBGP to improve the capacity of a growing network. The router must establish an iBGP peer relationship with its neighbor. The underlay network is already configured with the correct IP addresses. Which step should the engineer apply to complete this task?

  A. Implement multicast routing on the router to support BGP hellos.

  B. Configure the AS number for the router to share with its iBGP peers.

  C. Configure the new router as an iBGP route reflector to support multiple iBGP peers.

  D. Activate the BGP peers under the correct address family on the router.

  Correct Answer: C
