increase network bandwidth usage

Refer to the exhibit. This network is running EIGRP as the routing protocol and the internal networks are being advertised in EIGRP. Based on the link speeds, all traffic between London and Rome is getting propagated via Barcelona and the direct link betweenLondon and Rome is not being utilized under normal working circumstances. The EIGRP design should allow for efficiency in the routing table by minimizing the routes being exchanged. The link between London and Rome should be utilized for specific routes.Which two steps accomplish this task? (Choose two.)

Configure EIGRP route summarization on all the interfaces to summarize the internal LAN routes

Configure route leaking of summary routes on the link between London and Rome

Configure EIGRP route summarization on all the interfaces to summarize the internal LAN routes

Filter the routes on the link between London and Barcelona

Filter the routes on the link between London and Rome

Configure route leaking of summary routes on the link between London and Rome

Which action must be taken before new VoIP systems are implemented on a network to ensure that the network is ready to handle the traffic?

Evaluate bandwidth utilization and connection quality

Enable special requirements such as direct DID lines on pickup

Make recommendations to limit the size of the half-open session table on routers

An enterprise has identified these causes for inefficient CAPEX spending:• CAPEX planning is driven by technology and not by business objectives.• The CAPEX planning team lacks the data it needs to perform due diligence tasks.• The organizational structure lacks sufficient accountability and incentives.Which corporate cultural change contributes to improving the effectiveness of CAPEX spending?

Build a financial control function that delivers high-quality reports on operational expenses for business insight and financial reporting.

CxO-level staff must have a full technical understanding but the should not trust their technical leaders fully.

Adopt new organizational models that promote real accountability for ROI. not just revenue.EBITDA, and cash.

Marketing and product management divisions must reduce their CAPEX budgets significantly to drive the change.

A network security team uses a purpose-built tool to actively monitor the campus network, applications, and user activity. The team also analyzes enterprise telemetry data from IPFIX data records that are received from devices in the campus network. Which action can be taken based on the augmented data?

integration with an incident response plan

reduction in time to detect and respond to threats

integration with an incident response plan

adoption and improvement of threat-detection response

asset identification and grouping decisions

Which two actions must merchants do to be compliant with the Payment Card Industry Data Security Standard? (Choose two.)

establish risk management policies

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

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

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

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

A customer migrates from a traditional Layer 2 data center network into a new SDN-based spine-and-leaf VXLAN EVPN data center within the same location The networks are joined to enable host migration at Layer 2 What is the final migration step after hosts have physically migrated to have traffic flowing through the new network without changing any host configuration?

Shut down legacy Layer 3 SVIs and activate new preconfigured Layer 3 SVIs on VXLAN

Shut down legacy Layer 3 SVIs. clear ARP caches on all hosts being migrated and then configure the legacy VRRP address onto new VXLAN core switches

Increase VRRP priorities on new infrastructure over legacy VRRP values, then shut down legacy SVIs

Shut down legacy infrastructure to allow VXLAN gateways to become active

Shut down legacy Layer 3 SVIs and activate new preconfigured Layer 3 SVIs on VXLAN

A multinational enterprise integrates a cloud solution with these objectives* Achieve seamless connectivity across different countries and regions* Extend data center and private clouds into public clouds and provider-hosted cloudsWhat are two outcomes of deploying data centers and fabrics that interconnect different cloud networks?
