Questions # 17:

Company XYZ is migrating their existing network to IPv6. Some access layer switches do not support IPv6, while core and distribution switches fully support unicast and multicast routing. The company wants to minimize cost of the migration. Which migration strategy should be used?

Options:

A.

The access layer switches must support IGMP snooping at a minimum. Any switches that do not support IGMP snooping must be replaced.

B.

Upgrade the non-supporting switches. Otherwise, it will cause an issue with the migration.

C.

Layer 2 switches will not affect the implementation of IPv6. They can be included in the design in their current state.

D.

The access layer switches must support DHCPv6. Any switches that do not support DHCPv6 must be replaced.

Questions # 18:

Which network management framework can be used to develop a network architecture that contains business requirements analysis, gap analysis, and network diagrams as artifacts to be used for design and implementation later?

Options:

A.

TOGAF

B.

ITIL

C.

FCAPS

D.

Cobit

Expert Solution
Questions # 19:

How must the queue sizes be designed to ensure that an application functions correctly?

Options:

A.

Each individual device queuing delay in the chain must be less than or equal to the application required delay.

B.

The queuing delay on every device in the chain must be exactly the same to the application required delay.

C.

The default queue sizes are good for any deployment as it compensates the serialization delay.

D.

The sum of the queuing delay of all devices plus serialization delay in the chain must be less than or equal to the application required delay.

Expert Solution
Questions # 20:

Which statement about hot-potato routing architecture design is true?

Options:

A.

Hot-potato routing is the preferred architecture when connecting to content providers

B.

Hot-potato keeps traffic under the control of the network administrator for longer

C.

OSPF uses hot-potato routing if all ASBRs use the same value for the external metric

D.

Hot-potato routing is prone to misconfiguration as well as poor coordination between two networks

Expert Solution
Questions # 21:

A network hacker introduces a packet with duplicate sequence numbers to disrupt an IPsec session. During this, high-priority traffic is transmitted. What design parameter helps mitigate this?

Options:

A.

Classify and mark duplicate sequence packets

B.

Apply anti-replay window 4096

C.

Restrict keyword in IPsec tunnel

D.

Increase QoS shape policy

Expert Solution
Questions # 22:

Options:

A.

It is a well-understood architecture that provides scalability

B.

It is the best design for modern data centers

C.

It is the most optimal design but is highly complex

D.

It provides a simplified design

E.

Changes, upgrades, and new services can be introduced in a controlled and staged manner

Expert Solution
Questions # 23:

An enterprise that runs numerous proprietary applications has major issues with its on-premises server estate hardware, to the point where business-critical functions are compromised. The enterprise accelerates plans to migrate services to the cloud. Which cloud service should be used if the enterprise wants to avoid hardware issues yet have control of its applications and operating system?

Options:

A.

SaaS

B.

PaaS

C.

IaaS

D.

hybrid cloud

Expert Solution
Questions # 24:

Which MPLS TE design consideration is true?

Options:

A.

MPLS TE replaces LDP and the dependency of the IGP to identify the best path

B.

MPLS TE provides link and node protection

C.

MPLS TE optimizes the routing of IP traffic, given the constraints imposed by backbone capacity and application requirements

D.

MPLS TE requires Layer 3 VPN full-mesh topology deployment

Expert Solution
Questions # 25:

A customer migrates from a traditional Layer 2 data center network into a new SDN-based spine-and-leaf VXLAN data center within the same location Its applications cannot be readdressed and the customer does not want to perform the migration in a single operation How should the legacy network and new network be connected?

Options:

A.

via Layer 3 links to border leaf switches

B.

via a Layer 2 trunk and Layer 3 routed links to border leaf switches

C.

via a Layer 2 trunk and Layer 3 routed links to spine switches

D.

via a Layer 2 trunk to border leaf switches

Expert Solution
Questions # 26:

Company XYZ wants to deploy OSPF. The design plan requires that two OSPF networks be mutually redistributed at multiple locations and ensure end-to-end connectivity to all of the company's networks. Which technology can be used to fulfill the requirements while avoiding the creation of routing loops?

Options:

A.

Create a virtual link between ASBRs.

B.

Change the router ID for both ASBRs.

C.

Redistribute routes as external type 2 routes.

D.

Use route maps on ASBRs to filter routes with tags so they are not redistributed.

Expert Solution
Questions # 27:

Options:

A.

DAI

B.

IP Source Guard

C.

BEEP

D.

CPPr

E.

MPP

Expert Solution
Questions # 28:

You are designing a network running both IPv4 and IPv6 to deploy QoS. Which consideration is correct about the QoS for IPv4 and IPv6?

Options:

A.

IPv4 and IPv6 traffic types can use queuing mechanisms such as LLQ, PQ, and CQ.

B.

IPv6 packet classification is only available with process switching, whereas IPv4 packet classification is available with both process switching and CEF.

C.

IPv6 and IPv4 traffic types can use a single QoS policy to match both protocols.

D.

Different congestion management mechanisms need to be used for IPv4 and IPv6 traffic types.

Expert Solution
Questions # 29:

When designing a WAN that will be carrying real-time traffic, what are two important reasons to consider serialization delay? (Choose two.)

Options:

A.

Serialization delays are invariable because they depend only on the line rate of the interface.

B.

Serialization delays are variable because they depend on the line rate of the interface and on the type of the packet being serialized.

C.

Serialization delay is the time required to transmit the packet on the physical media.

D.

Serialization delays are variable because they depend only on the size of the packet being serialized.

E.

Serialization delay depends not only on the line rate of the interface but also on the size of the packet.

Expert Solution
