Questions # 131:

A service provider hires you to design its new managed CE offering to meet these requirements:

The CEs cannot run a routing protocol with the PE.

Provide the ability for equal or unequal ingress load balancing in dual-homed CE scenarios.

Provide support for IPv6 customer routes.

Scale up to 250,000 CE devices per customer.

Provide low operational management to scale customer growth.

Utilize low-end (inexpensive) routing platforms for CE functionality.

Which tunneling technology do you recommend?

Options:

A.

FlexVPN

B.

point-to-point GRE

C.

DMVPN

D.

LISP

Questions # 132:

Flow is a set of IP packets passing an observation point in the network during a certain time interval. A flow could consist of ail packets in a specific transport connection or a media stream. Packet flow temporal efficiency can be affected by one-way delay Drag and drop the delay types from the left onto the corresponding definitions on the right Not all are used

Question # 132

Questions # 133:

By monitoring the effects of the design variations, you can characterize the relative resilience of the design. Which method involves disturbing the network by removing an active interface and monitoring how the change is handled by the network?

Options:

A.

randomized configuration

B.

nondeterministic analysis

C.

failover testing

D.

passive monitoring

Questions # 134:

Traditionally networks handled static web pages e-mail and routine client/server traffic Today enterprise networks must handle more sophisticated types of network applications that include voice and video Applications place increasing demands on IT infrastructures as they evolve into highly visible services that represent the face of the business to internal and external audiences The large amount and variety of data requires that the modern network be aware of the content earned across it to optimally handle that content. Which service provide this intelligence?

Options:

A.

centralized network services

B.

application networking services

C.

network infrastructure services

D.

modular infrastructure services

Questions # 135:

Which component of the SDN architecture automatically ensures that application traffic is routed according to policies established by network administrators?

Options:

A.

Packet forwarding engine

B.

Northbound API

C.

Southbound API

D.

SDN controller

Questions # 136:

Which two statements describe the functionality of OSPF packet-pacing timers? (Choose two.)

Options:

A.

The group-pacing timer controls the interval that is used for group and individual LSA refreshment

B.

OSPF flood-pacing timers allow dynamic control of the OSPF transmission queue size

C.

OSPF retransmission-pacing timers allow control of interpacket spacing between consecutive link-state update packets in the OSPF retransmission queue

D.

OSPF retransmission-pacing timers allow control of packet interleaving between nonconsecutive link-state update packets in the OSPF retransmission queue

E.

OSPF flood-pacing timers allow control of interpacket spacing between consecutive link-state update packets in the OSPF transmission queue

Questions # 137:

Which extensions to GRE tunneling provide session tracking and in-order packet delivery in exchange for additional state stored in tunnel endpoints?

Options:

A.

GRE Protocol Type and Checksum extension fields.

B.

GRE Version and Reserved0 extension fields.

C.

No extension fields are available in the GRE header to track session data and packet sequences.

D.

GRE Key and Sequence number extensions.

Questions # 138:

Two routers R1 and R2 are directly connected through an Ethernet link. Both routers are running OSPF over the Ethernet link and OSPF has been registered with BFD. R1 has been set up to transmit BFD at a 50 ms interval, but R2 can receive only at a 100 ms rate due to platform limitations. What does this mean?

Options:

A.

After the initial timer exchange, R2 sets its transmission rate to the R1 Desired Min TX interval

B.

After the initial timer exchange, R1 sets its transmission rate to the R2 Required Min RX interval

C.

Timers renegotiate indefinitely, so the timer exchange phase never converges

D.

R2 sets the P-bit on all BFD control packets until R2 sends a packet with the F-bit set

Questions # 139:

A network engineering team is in the process of designing a lab network for a customer demonstration. The design engineer wants to show that the resiliency of the MPLS Traffic Engineering Fast Reroute solution has the same failover/failback times as a traditional SONET/SDH network (around 50 msec). In order to address both link failure and node failure within the lab topology network, which type of the MPLS TE tunnels must be considered for this demonstration?

Options:

A.

TE backup tunnel

B.

Next-hop (NHop) tunnel

C.

FRR Backup tunnel

D.

Next-next-hop (NNHop) tunnel

Questions # 140:

Which parameter is the most important factor to consider when deciding service placement in a cloud solution?

Options:

A.

Data replication cost

B.

Application structure

C.

Security framework implementation time

D.

Data confidentiality rules
