Question 3:
Refer to the exhibit.
Traffic was equally balanced between Layer 3 links on core switches SW1 and SW2 before an introduction of the new video server in the network. This video server uses multicast to send video streams to hosts and now one of the links between core switches is over utilized.

Question 6:
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.

Correct Answer: D
Question 7:
Refer to the exhibit.

A. Configure the AS-set attribute to allow only routes from AS 111 to be propagated to the neighbor ASs.
B. Use the local preference attribute to configure your AS as a non-transit\’\’ AS.
C. include an AS path access list to send routes to the neighboring ASs that only have AS 111 in the AS path field.
D. Include a prefix list to only receive routes from neighboring ASs.
Correct Answer: C
Question 8:
Which BGP feature provides fast convergence?
A. BGP PIC
B. BGP-EVPN
C. BGP FlowSpec
D. BGP-LS
Correct Answer: A
Reference:
Question 9:
Refer to the exhibit.
As part of a redesign project, you must predict multicast behavior. What happens to the multicast traffic received on the shared tree (*,G), if it is received on the LHR interface indicated*?
A. It is dropped due to an unsuccessful RPF check against the multicast source
B. It is switched give that no RPF check is performed
C. It is switched due to a successful RPF check against the routing table
D. It is dropped due to an unsuccessful RPk8t8ck against the multicast receiver.
Correct Answer: C
https://www.cisco.com/c/en/us/support/docs/ip/ip-multicast/16450- mcastguide0.html
When a multicast packet arrives on an interface, the RPF process checks to ensure that this incoming interface is the outgoing interface used by unicast routing in order to reach the source of the multicast packet.
This RPF check process prevents loops. Multicast routing does not forward a packet unless the source of the packet passes a RPF check. Once a packet passes this RPF check, multicast routing forwards the packet based only upon the destination address.
Question 10:
A business customer deploys workloads in the public cloud. Now the customer network faces governance issues with the flow of IT traffic and must ensure the security of data and intellectual property.
Which action helps to identify the issue for further resolution?
A. Set up a secure tunnel from customer routers to ensure that traffic is protected as it travels to the cloud service providers.
B. Send IPFIX telemetry data from customer routers to a centralized collector to identify traffic to cloud service providers
C. Build a zone-based firewall policy on Internet edge firewalls that collects statistics on traffic sent to cloud service providers
D. Apply workload policies that dictate the security requirements to the workloads that are placed in the cloud.
Correct Answer: B
Question 11:
What is the most important operational driver in building a resilient and secure modular network design?
A. Dependencies on hardware or software that is difficult to scale
B. Minimize app downtime
C. Reduce the frequency of failures requiring human intervention
D. Increase time spent on developing new features
Correct Answer: C
Question 12:
Company XYZ plans to run OSPF on a DMVPN network. They want to use spoke-to-spoke tunnels in the design.
What is a drawback or concern in this type of design?
A. Additional host routes will be inserted into the routing tables
B. Manual configuration of the spokes with the appropriate priority will be needed
C. There will be split-horizon issue at the hub
D. Manual configuration of the spoke IP address on the hub will be needed
Correct Answer: B
Question 13:
Various teams in different organizations within an enterprise are preparing low-level design documents to capture network parameters using a Waterfall project model:
hardware sizing and power consumption
Layer 2 and layer 3 services parameters
configuration of all control plane protocols
Input from relevant stakeholders was captured at the start of the project, and the project scope has been defined based on the parameters above.
What impact will it have on documentation and project deliverables if the stakeholders ask to have changes carried out in the network before the information has been captured?
A. This provides more opportunity to think outside the box.
B. Rework is expected before the delivery.
C. Significant effort and time are required.
D. This provides a flexible approach to incorporate changes.
Correct Answer: B
Redo work is expected for whole project, but the situation of the question is more focus on very early stage.
Waterfall can require that a phase be fully completed before proceeding to the next one, and it\’s extremely difficult to go back if you miss anything. That means you and your team must check every box before moving on, or there could be a lot of rework needed.
This could easily derail your schedule since there are many dependent relationships between tasks—every day of delay is another day added to your overall schedule. https://www.clearpointstrategy.com/blog/waterfall-project-management
Question 14:
Which technology supports antispoofing and does not have any impact on encryption performance regardless of packet size?
A. MACsec
B. IP source guard
C. DHCP snooping with DAI
D. IPsec
Correct Answer: B
IP source guard is a security feature that helps prevent IP spoofing attacks by allowing only packets with valid source IP addresses to pass through a network device. It uses a combination of source IP address filtering and DHCP snooping to determine the validity of the source IP address.
Question 15:
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?
A. 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
B. Increase VRRP priorities on new infrastructure over legacy VRRP values, then shut down legacy SVIs
C. Shut down legacy infrastructure to allow VXLAN gateways to become active
D. Shut down legacy Layer 3 SVIs and activate new preconfigured Layer 3 SVIs on VXLAN
Correct Answer: D
