Questions 23

An MPLS service provider is offering a standard EoMPLS-based VPLS service to Customer A, providing Layer 2 connectivity between a central site and approximately 100 remote sites. Customer A wants to use the VPLS network to carry its internal multicast video feeds which are sourced at the central site and consist of 20 groups at Mbps each. Which service provider recommendation offers the most scalability?

Options:

EoMPLS-based VPLS can carry multicast traffic in a scalable manner

Use a mesh of GRE tunnels to carry the streams between sites

Enable snooping mechanisms on the provider PE routers

Replace VPLS with a Layer 3 MVPN solution to carry the streams between sites

Questions 24

With virtualization being applied in many parts of the network, every physical link is likely to carry one or more virtual links, but what is a drawback in cases like this?

Options:

unneeded tunneling

fate sharing

serialization delay

bandwidth utilization

Questions 25

Company XYZ was not satisfied with the reconvergence time OSPF is taking. BFD was implemented to try to reduce the reconvergence time, but the network is still experiencing delays when having to reconverge. Which technology will improve the design?

Options:

OSPF fast hellos

BFD echo

Change the protocol to BGP

Change the OSPF hello and dead intervals

Questions 26

A global e-commerce company is expanding its operations and planning to migrate its entire infrastructure to a hybrid cloud solution. They are concerned about data governance and want to ensure that their customers ' data is treated with utmost respect to sovereignty and privacy. What is an appropriate approach?

Options:

Replicate customer data across all data centers globally to ensure data redundancy and compliance with local data regulations.

Utilize a cloud provider that offers region-specific data centers to store customer data within the same geographic region.

Encrypt all customer data and store it in a public cloud environment to benefit from advanced security measures.

Implement strict access controls for customer data and store it in a single central data center to maintain data sovereignty.

Questions 27

Questions 28

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.

Questions 29

Drag and drop the end-to-end network virtualization elements from the left onto the correct network areas on the right.
