Question 36

A small organization of 20 employees is looking to deliver a network design service for modernizing customer networks to support advanced solutions.

Project scope and weekly progress should be visualized by the management.

Always consider feedback and make changes accordingly during the project.

Should consider flexibility to change scope at the point of time.

Which project methodology meets the requirements and have the least impact on the outcome?

Options:

Scrum

LEAN

Kanban

Six-Sigma

Question 37

What is a disadvantage of the traditional three-tier architecture model when east west traffic between different pods must go through the distribution and core layers?

Options:

low bandwidth

security

scalability

high latency

Question 38

Which two statements about MLD snooping are true? (Choose two)

Options:

When MLD snooping is enabled, QoS is automatically enabled.

A VLAN can support multiple active MLD snooping queries, as long as each one is associated to a different

multicast group.

AN MLD snooping querier election occurs when any MLD snooping querier goes down or if there is an IP

address change on the active querier.

When multiple MLD snooping queriers are enabled in a VLAN, the querier with the lowest IP address in the

VLAN is elected as the active MLD snooping querier.

Question 39

Company XYZ is in the process of identifying which transport mechanism(s) to use as their WAN technology. Their main two requirements are.

• a technology that could offer DPI, SLA, secure tunnels, privacy, QoS, scalability, reliability, and ease of management

• a technology that is cost-effective

Which WAN technology(ies) should be included in the design of company XYZ?

Options:

Software-defined WAN should be the preferred choice because it complements both technologies, covers all the required features, and it is the most cost-effective solution.

Internet should be the preferred option because it is cost effective and supports BFD, IP SLA. and IPsec for secure transport over the public Internet.

Both technologies should be used. Each should be used to back up the other one; where the primary links are MPLS, the internet should be used as a backup link with IPsec (and vice versa).

MPLS meets all these requirements and it is more reliable than using the Internet. It is widely used with defined best practices and an industry standard.
