Fabric edge nodes update the HTDB based on CAPPWAP messaging from the AP

B.

Fabric WLCs update the HTDB as new clients connect to the wireless network

C.

Border nodes first register endpoints and then update the HTDB

D.

Fabric APs update the HTDB with the clients' ElD and RLOC

An architect must address sustained congestion on the access and distribution uplink of
network. QoS has already been implemented and optimized, but it is no longer effective in
ensuring optimal network performance. Which two solutions should the architect use to
improver network performance? (Choose two)

A.

Reconfigure QoS based on the IntServ model

B.

Utilize random early detection to manage queues

C.

Implement higher-speed uplink interfaces

D.

Bundle additional uplinks into logical EtherChannels

E.

Configure selective packet discard to drop noncritical network traffic

A company's security policy requires that all connections between sites be encrypted in a manner that does not require maintenance of permanent tunnels. The sites are connected through a private
MPLS-based service that
uses a dynamically changing key and spoke-to-spoke communication. Which type of
transport encryption must
be used in this environment?

A.

GETVPN

B.

DMVPN

C.

GRE VPN

D.

standard IPsec VPN

An architect is designing a network that will utilize the spanning tree protocol to ensure a
loop-free topology. The network will support an engineering environment where it is
necessary for end users to connect their own network switches for testing purposes. Which
feature should the architect include in the design to ensure the spanning tree topology is
not affected by these rogue switches?

A.

BPDU Skew Detection

B.

BPDU guard

C.

loop guard

D.

root guard

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

Which consideration must be taken into account when using the DHCP relay feature in a
Cisco SD-Access Architecture?

A.

DHCP-relay must be enabled on fabric edge nodes to provide the correct mapping of DHCP scope to the local anycast gateway.

B.

A DHCP server must be enabled on the border nodes to allow subnets to span
multiple fabric edges.

C.

DHCP servers must support Cisco SD-Access extensions to correctly assign IPs
to endpoints in an SD-Access fabric with anycast gateway.

D.

DHCP Option-82 must be enabled to map the circuit IP option to the access fabric
node where the DHCP discover originated.

An engineer must propose a QoS architecture model that allows an application to inform
the network of its traffic profile and to request a particular type of service to support its
bandwidth and delay requirements. The application requires consistent and dedicated
bandwidth end to end. Which QoS architecture model meets these requirements?

A.

DiffServ

B.

LLQ

C.

WRED

D.

IntServ

An engineer must design a scalable QoS architecture that allows the separation of the traffic into classes on predefined business requirements. The design must also utilize the
differentiated services code points as the QoS priority descriptor value and support at least
10 levels of classification. Which QoS technology should the engineer include in the design?

A.

RSVP

B.

Diffserv

C.

Best effort

D.

Interserv
