Question # 42

What are the two purpose of the RPF check in multicast routing?

Options:

A.  

to ensure that multicast packets are forwarded if they arrived on the interface used to route traffic back to the source address

B.  

to ensure that multicast packets are forwarded if they arrived on the interface used to route traffic to the destination address

C.  

to ensure that multicast packets, no matter the interface they arrived on. are forwarded out all interfaces

D.  

to ensure that multicast packets are dropped if they arrived on the interface used to route traffic to the destination address

E.  

to ensure that multicast packets are dropped if they arrived on the interface used to route traffic back to the source address

Question # 43

Refer to the exhibit. An architect must design an IP addressing scheme for a multisite network connected via a WAN transit. The campus site must accommodate 12,000 devices and the branch sites must accommodate 1,000 devices. Which address scheme optimizes network device resources, contains convergence events to the different blocks of the network, and ensures future growth of the network?

Options:

A.  

Campus: 10.0.0.0/18

• Branch1: 10.0.192.0/21

• Branch2: 10.0.200.0/21

B.  

• Campus: 10.0.0.0/16

• Branchi: 10.255.0.0/20

• Branch2: 10.255.16.0/20

C.  

• Campus: 10.0.0.0/10

• Branch1: 10.64.0.0/10

• Branch2: 10.128.0.0/10

D.  

• Campus: 10.0.0.0/20

• Branch1: 10.0.64.0/21

Branch2: 10.0.128.0/21

Question # 45

Question # 45

Refer to the exhibit. Which process does the Ethernet LMI protocol follow that is defined by the MEF 16 Technical Specification?

Options:

A.  

communicates ENI and EVC attributes to the CE

B.  

notifies the CE of the availability state of a configured EVC

C.  

broadcasts multicast network routes from the CE to the PE

D.  

broadcasts to all subnets from the CE when an EVC is added

Question # 46

An engineer must propose a solution for a campus network that includes the capability to create multiple Layer 3 virtual networks. Each network must have its own addressing structure and routing table for data forwarding. The solution must be scalable to support hundreds of virtual networks and allow simple configuration and management with minimal administrative overhead. Which solution does the engineer recommend?

Options:

A.  

hop-by-hop EVN

B.  

multihop MPLS core

C.  

multihop IPsec tunneling

D.  

hop-by-hop VRF-Lite

Question # 47

Options:

Discussion 0
Question # 48

Which design consideration must be made when dual WAN Edge routers are deployed at a branch site?

Options:

A.  

Use BGP AS-path prepending to influence egress traffic and use MED to influence ingress traffic from the branch.

B.  

HSRP priorities must match the OMP routing policy to prefer one WAN Edge over the other.

C.  

Traffic must be symmetrical as it egresses the WAN Edges and returns from remote sites for DPI to function properly.

D.  

Configure BFD between WAN Edge routers to detect sub-second link failures.

Question # 49

How is internet access provided to a WAN edge router that is connected to a MPLS transport link?

Options:

A.  

OMP advertises a default route from a WAN Edge router that is connected to the MPLS and internet transport networks

B.  

Internet access must be provided at the WAN Edge router through either a 4G/5G link or local Internet circuit

C.  

An extranet must be provided in the MPLS transport network to allow private traffic to reach the public internet

D.  

TLOC extensions are used to route traffic to a WAN Edge router that is connected to the Internet transport network

Question # 50

An engineer is designing a networking solution to allow two hosts to communicate—one host located within the company A network and the other within the company B network. The two companies have no other plans for future additional connections. Both companies want to use a single secure and encrypted internet connection, and the configuration must be as simple as possible. Which network solution must the engineer choose?

Options:

A.  

single DMVPN with EIGRP routing

B.  

routed IPsec tunnel with OSPF routing

C.  

policy-based IPsec tunnel with static routing

D.  

MPLS VPN provided service with BGP routing
