Refer to the exhibit. An architect designs a BGP policy for a customer that requires load sharing of the links that connect with the upstream service provider. The customer has these requirements: • The inbound traffic destined to network 10.1.1.0/24 must transit the R3-R1 link, and if the link fails, all inbound traffic must transit the R4-R2 link.
• The inbound traffic destined to network 10.1.2.0/24 must transit the R4-R2 link, and if the link fails, all inbound traffic should transit the R3-R1 link.
Which solution must the architect choose?
Refer to the exhibit.

A network engineer is designing a network for AS100. The design should ensure that all traffic enters AS100
via link 1 unless there is a network failure. In the event of a failure, link 2 should function as the path for
incoming traffic. Which solution should the design include?
Refer to the exhibit. An architect must create a stable and scalable EIGRP solution for a customer. The design must:
•conserve bandwidth, memory, and CPU processing
•prevent suboptimal routing
•avoid any unnecessary queries
Which two solutions must the architect select? (Choose two.)
Refer to the exhibit An engineer is designing a hierarchical ISIS solution for an enterprise customer with these requirements
Users in areas 25 and 55 send and receive traffic from both backbone areas
Link flaps in areas 35 and 45 must not impact other areas
Routers will double within the next 12 months in areas 35 and 45
Which design must the engineer select?
What is a challenge of the SaaS model?
Refer to the exhibit A network administrator plans to announce the site subnets to the WAN using route summarization instead of announcing every subnet. What is the smallest summary route that should be used to encompass all subnets at the site?
Drag and drop the descriptions from the left onto the categories they apply to on the right.
Refer to the exhibit. An architect must design a resilient gateway solution based on these requirements:
VLAN 10 and VLAN 11 support voice and video applications.
Link and node failures must have minimal impact on traffic.
Provide protection against false hello packets.
Support IPv6.
Which solution must the architect choose?
Drag and drop the components in a Cisco SD-Access architecture from the left onto their descriptions on the right.
An architect is designing a connectivity solution for a customer's two small branch offices. The customer wants a cost-effective design, no routing overload, and some down time during the year is acceptable. Which connectivity solution must the architect choose?
Refer to the exhibit. An architect working for a service provider with an employee ID: 4763:44:876 must design a Layer 2 VPN solution that supports:
transparency of service provider devices
direct communication between CE routers attached to the same VLAN
Which solution must the design include?
Which design consideration should be observed when EIGRP is configured on Data Center switches?
An engineer is designing a QoS policy that queues excess packets for later transmission. Which mechanism must be included in the design?
Which feature provides the capability for intra-VN traffic filtering and control within the Cisco SO-Access architecture?
What is the purpose of a TLOC extension in a Cisco SD-WAN network fabric?
A customer is undergoing a WAN re-architecture and wants to design QoS policies for remote sites that have low bandwidth. What must be considered to have CBWFQ configured in the parent and child policies in an end-to-end QoS design?
Drag and drop the model-driven telemetry considerations from the left onto the modes they apply to on the right.
A company wants to deploy IPv6 within its existing network infrastructure. All current infrastructure equipment supports IPv6, and the company wants a migration strategy that must not require purchasing additional equipment The plan must keep operational management costs low. support IPv6 multicast, and allow applications to migrate using DNS. Which strategy must the company choose?
Refer to the exhibit. An engineer is planning an IPv4 to IPv6 migration solution for a customer. The routers in the network can support IPv4 and IPv6, except for the DWDM routers. The DWDM routers provide a Layer 2 link in which the routers peer directly with each other across a DWDM circuit. The circuit also provides connectivity between the mail servers. Which IPv6 migration technique must the engineer deploy?
How are wireless endpoints registered in the HTDB in a Cisco SD-Access architecture?
