DRAG DROP

An enterprise organization currently provides WAN connectivity to their branch sites using MPLS technology, and the enterprise network team is considering rolling out SD-WAN services for all sites.

With regards to the deployment planning, drag and drop the actions from the left onto the corresponding steps on the right.

What best describes the difference between Automation and Orchestration?

A. Automation refers to an automatic process for completing a single task and Orchestration refers to assembling and coordinating a set of tasks and conditions.

B. Automation describes a hands-off configuration process while Orchestration refers to sets of automation tasks that require the network administrator to coordinate

C. Automation refers to an automatic process for completing multiple tasks with conditions and Orchestration refers to executing tasks in parallel.

D. Automation refers to scripting languages (Python. Ansible etc.) and Orchestration refers to commercial products that control configuration deployment

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?

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

What are two descriptions of network optimization? (Choose two.)

A. maintain high availability

B. proactive network management

C. network redesign

D. network health maintenance

E. identify network requirements

Company XYZ is planning to deploy primary and secondary (disaster recovery) data center sites. Each of these sites will have redundant SAN fabrics and data protection is expected between the data center sites. The sites are 100 miles (160 km) apart and target RPO/RTO are 3 hrs and 24 hrs, respectively. Which two considerations must Company XYZ bear in mind when deploying replication in their scenario? (Choose two.)

A. Target RPO/RTO requirements cannot be met due to the one-way delay introduced by the distance between sites.

B. VSANs must be routed between sites to isolate fault domains and increase overall availability.

C. Synchronous data replication must be used to meet the business requirements

D. Asynchronous data replication should be used in this scenario to avoid performance impact in the primary site.

E. VSANs must be extended from the primary to the secondary site to improve performance and availability.

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

1.

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

2.

a technology that is cost-effective

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

A. 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.

B. 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.

C. 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).

D. 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.

Which two aspects are considered when designing a dual hub dual DMVPN cloud topology? (Choose two )

A. will only work with single-tier headend architecture

B. hub sites must connect to both DMVPN clouds

C. recommended for high availability

D. spoke-to-spoke traffic will transit the hub unless spokes exchange dynamic routing directly

E. requires all sites to have dual Internet connections

Which mechanism provides Layer 2 fault isolation between data centers?

A. fabric path

B. OTL

C. advanced VPLS

D. LISP

E. TRILL

Company XYZ has a multicast domain that spans across multiple autonomous systems. The company wants to choose a technology that provides simplified and controlled approach to interconnecting the multicast domains. Which technology is the best fit for this purpose?

A. MSDP

B. PIM SSM

C. MPLS

D. PIM sparse mode

Company XYZ is redesigning their QoS policy. Some of the applications used by the company are real-time applications. The QoS design must give these applications preference in terms of transmission. Which QoS strategy can be used to fulfill the requirement?

A. weighted fair queuing

B. weighted random early detection

C. low-latency queuing

D. first-in first-out
