Question 2

Refer to the exhibit. ISP A offers an L2VPN private connection service for business customers.

Question 3

Refer to the exhibit. Company A has two sites, which are connected to PE1 and PE4 respectively.
The route targets have been configured for the import and export values. PE1 and PE4 have established BGP connections for IPv4 and VPNv4, but the two customer A sites cannot communicate. Which two actions must the network engineer take to resolve the issue? (Choose two.)

A. Set the route-target import values on PE4 to 101:101 B. Set the route-target export value on PE4 to 101:101 C. Set the route-target import value on PE1 to 104:104. D. Set the route-target import value on PE4 to 101:101 and 104:104. E. Set the route-target export values on PE1 to 101:101 and 104:104.

Question 4

Refer to the exhibit. A customer carrier running MPLS VPN wants to utilize a backbone carrier to forward traffic and exchange VPNv4 prefixes between the two customer carrier networks depicted.
Which two sets of routers must establish MP-iBGP sessions? (Choose two.)

A. BB-PE-A and BB-PE-B B. CC-PE-A and BB-PE-A C. BB-PE-A and BB-P-A D. BB-PE-A and CC-PE-B E. CC-PE-A and CC-P-A F. CC-PE-A and CC-PE-B

Router 1 has statically defined thresholds for data MDT. D. Router 1 will accept multicast routes with a route-target of 12:1.

Question 7

Which action must an engineer take when configuring SR-TE using OSPF?

A. Configure all OSPF links as point-to-multipoint. B. Enable segment routing under the OSPF routing process. C. Establish direct neighbor relationships between all OSPF devices in the network. D. Implement PIM-SM to share routing updates throughout the OSPF network.

Question 8

Refer to the exhibit. Edge router R1 is installed at a Tier 1 ISP using OSPF with TE extensions in area 0 as an underlayer routing protocol. The tunnel is configured with explicit path-option path1 with bandwidth 300. A network engineer recently replaced a failed PSU module on R1 and reloaded the router. Then, the engineer configured mpls traffic-eng tunnel path-option protect for one of the customer's MPLS LSPs. After the configuration, the LSP went down with the error message LSP-ERROR-Indication: Path Setup Failed. Which action must the engineer take to resolve the issue?

A. Configure mpls mtu 1546 under all interfaces. B. Configure mpls traffic-eng area 0 under the OSPF configuration. C. Configure path-option 1 dynamic under explicit path path1 D. Configure mpls traffic-eng tunnel-path 10.0.0.1 10.0.0.3 10.0.0.2 path-option 10 explicit path1 under the global configuration.

Question 9

How do Ethernet virtual circuits provide a way for service providers to maximize the use of VLAN tags?

A. They separate the classification and forwarding concepts for VLAN tagging which allows multiple switch ports to use the same VLAN ID without it being configured globally. B. They add an additional tag to VLANs that allows up to two switch ports to use the same globally configured VLAN ID. C. They redefine the VLAN tag to include classification, forwarding, and QoS using MPLS labels and EXP bits D. They assign VLAN IDs to VTP domains so that the same VLAN ID are used more than once globally.

Devices on the network use LSAs to share routes between P routers in the network. D. Devices on the network use MPLS labels to share VPN routes between P routers in the network.

Question 11

Refer to the exhibit. A customer connected to a service provider is running VPLS to extend its Layer 2 domain across hosts in two geographic regions. Servers at each site support local and remote hosts. An engineer configured PE1 and PE2 to facilitate the customer's traffic requirements, but the circuit is down.
Which action must the engineer take to resolve the issue?

A. Change the I2transport protocol on the network to IP. B. Change the VC ID on PE1 and PE2 to match the VPN ID. C. Change the VC ID on PE1 to match the value on PE2. D. Change the subnet mask of the network for the connection to /30.
