Company XYZ, a global content provider, owns data centers on different continents Their data center design involves a standard three-layer design with a Layer 3-only core VRRP is used as the FHRP They require VLAN extension across access switches in all data centers, and they plan to purchase a Layer 2 interconnection between two of their data centers in Europe in the absence of other business or technical constraints which termination point is optimal for the Layer 2 interconnection?

at the aggregation layer because it is the Layer 2 to Layer 3 demarcation point

at the core layer, to offer the possibility to isolate STP domains

at the access layer because the STP root bridge does not need to align with the VRRP active node

at the core layer because all external connections must terminate there for security reasons

at the aggregation layer because it is the Layer 2 to Layer 3 demarcation point

The Agile Manifesto is a document that defines the key values and principles behind the Agile philosophy and helps development teams work more efficiently and sustainably Each of the four key values is split into two sections a left-hand side and a right-hand side In other words, though there is value in the items on the right we value the items on the left more What is one of the key values of the Agile Manifesto?

individuals and interactions over processes and tools

comprehensive documentation over working software

contract negotiation over customer collaboration

individuals and interactions over processes and tools

following a plan over responding to change

Refer to the exhibit. The network 10.10.0 .0/16 has been redistributed to OSPF processes and the best path to the destination from R1 has been chosen as R1-R2-R3 A failure occurred on the link between R2 and R3 and the path was changed to R1-R4-R5-R3 What happens when the link between R2 and R3 is restored'?

The path reverts to R1-R2-R3 because this was the previous best path

The path R1-R4-R5-R3 continues to be the best path because the metric is better

The path reverts back to R1-R2-R3 because the route type is E1

The path R1-R4-R5-R3 continues to be the best path because OSPF does not compare the metrics between two domains

The path reverts to R1-R2-R3 because this was the previous best path

What is the most important operational driver when building a resilient and secure modular network design?

Reduce the frequency of failures requiring human intervention

Increase time spent on developing new features

A business wants to centralize services via VDI technology and to replace remote WAN desktop PCs with thin client-type machines to reduce operating costs Which consideration supports the new business requirement?

The WAN should offer low latency and be resized

VDI servers should be contained centrally within a DMZ

The thin client traffic should be placed in a WAN QoS priority queue

VDI servers should be contained within dedicated VLANs in each branch location

The WAN should offer low latency and be resized

Refer to the exhibit. Company XYZ BGP topology is as shown in the diagram. The interface on the LA router connected toward the 10.1.5.0/24 network is faulty and is going up and down, which affects the entire routing domain. Which routing technique can be used in the routing policy design so that the rest of the network is not affected by the flapping issue?

Use route aggregation on LA router to summarize the 10.1.4.0V24, 10.1.5.0724, 10.1.6.0/24. and 10.1.7.0/24 networks toward Chicago

Use route dampening on LA router for the 10 1 5 0/24 network so that it does not get propagated when it flaps up and down

Use route filtering on Chicago router to block the 10.1.5.0/24 network from coming in from the LA router

Use route filtering on LA router to block the 10.15.0/24 network from getting propagated toward Chicago and New York

Use route aggregation on LA router to summarize the 10.1.4.0V24, 10.1.5.0724, 10.1.6.0/24. and 10.1.7.0/24 networks toward Chicago

In a redundant hub and spoke 'wheel' design, all spokes are connected to the hub, and spokes are connected to other spokes as well. During failure on one spoke link, the traffic from that site can be sent to a neighboring site for it to be forwarded to the hub site. But during peak hours, a link is overloaded and traffic is re-routed to a neighbor, which subsequently becomes overloaded. This overload results in network traffic oscillation as the load varies at each spoke site. This design provides more redundancy but not more resiliency because the routing protocol must process many alternate paths to determine the lowest cost path. Which two design changes help to improve resilience in this case? (Choose two.)

Increase unequal-cost parallel paths.

Use two links to each remote site instead of one.

Increase the number of redundant paths considered during the routing convergence calculation.

Eliminate links between every spoke.

Increase routing protocol convergence timers.

Increase unequal-cost parallel paths.

Use two links to each remote site instead of one.

Which two descriptions of CWDM are true? (Choose two)

shares the same transmission window as DWDM

A large enterprise customer is planning a new WAN connection to its headquarters. The current architecture is dual homed with static routing, but users complain when a specific link fails. Failure of the other link does not affect any services or applications. The new WAN connection must provide the headquarters with a resilient network design and increase the return on investment.Which solution should be recommended to the customer?

Use dynamic routing toward the WAN.

Implement granular quality of service on the links.

Use dynamic routing toward the WAN.

Add an additional link to the WAN.

A large enterprise customer has a single router that uses two active/active 10-Mbps internet links in one of its offices. Each link currently handles approximately 7 Mbps of traffic, which is close to the full link capacity.When a link fails, the failure leads to significantly degraded performance of all applications. Static routing is used. The current ISP cannot deliver additional bandwidth capacity on the existing links. The customer needs a network design that is resistant to failure, but does not increase CAPEX. Which solution should be proposed to the customer?

Use dynamic routing for equal-cost multipath.

Implement quality of service on the current links.

Add a third link to the current router.

Add an additional edge router connected to a second ISP.

Use dynamic routing for equal-cost multipath.

A network hacker is trying to interrupt the transport packet on IPSEC. A packet with duplicate sequence numbers is introduced. The customer sends high-priority traffic during this window. Which design parameter should be considered to mitigate this issue?

Classify and Mark duplicate sequence packets.

Restrict keywork in IPSEC Tunnel.

In the absence of other business or technical constraints, which termination point is optimal for the Layer 2 interconnection?

at the core layer, to otter the possibility to isolate STP domains

at me aggregation layer because it is the Layer 2 to Layer 3 demarcation point
