A customer is discussing QoS requirements with a network consultant. The customer has specified that endto-end path verification is a requirement. Which QoS solution meets this requirement?

A. IntServ model with RSVP to support the traffic flows

B. DiffServ model with PHB to support the traffic flows

C. marking traffic at the access layer with DSCP to support the traffic flows

D. marking traffic at the access layer with CoS to support the traffic flows

When IPsec VPNs are designed, what is a unique requirement if support for IP Multicast is required?

A. encapsulation of traffic with GRE or VTI

B. IPsec forwarding using transport mode

C. additional bandwidth for headend

D. IPsec forwarding using tunnel mode

An architect is working on a design to connect a company's main site to several small to medium- sized remote branches. The solution must include redundant WAN links, but the customer has a limited budget and wants the ability to increase the link speed easily in the future. QoS will not on the branch routers so there is no need for consistent end-to-end QoS. Which solution does the architect propose?

A. dual-homed WAN MPLS with single edge router

B. dual-homed Internet with a single edge router running a site-to-site VPN topology

C. dual-homed WAN MPLS and Internet links via dual edge routers

D. dual-homed Internet with dual edge routers running a hub-and-spoke VPN topology

A company uses cloud-based applications for voice and video calls, file sharing, content sharing, and messaging. During business hours, these applications randomly become slow and unresponsive. However, other applications work smoothly with the current applied QoS polices. Which solution must the company choose to resolve the issue?

A. Identify the applications with NBAR2 and allocate the required bandwidth accordingly.

B. Identify the port used by each application and apply a minimum bandwidth guarantee.

C. Identify the applications and reserve the required bandwidth on the perimeter routers.

D. Identify the application ports, create groupings, and rate-limit the required bandwidth.

Which two overlay network design considerations must be made for a Cisco SD-Access network? (Choose two.)

A. LAN automation for deployment

B. Layer 3 to the access design

C. Reduce subnets and simplify DHCP management

D. Dedicated IGP process for the fabric

E. Avoid overlapping IP subnets
