An engineer must design a solution to connect a customer to the Internet. The solution will
include a Layer 3 circuit with a CIR of 50 Mbps from the service provider. The hand-off from
the provider's switch to the customer's router is 1Gbps. Which solution should the engineer
include to prevent potential issues with choppy voice traffic?
A.
Reduce the bandwidth of the connection to the router.
B.
Implement hierarchical QoS with a parent policing policy.
C.
Implement hierarchical QoS with a parent shaping policy.
D.
Add a bandwidth statement to the router interface.
Implement hierarchical QoS with a parent shaping policy.

A customer has several remote sites connected with their headquarters through microwave links. An engineer must propose a backup WAN solution based on these conditions:
Which backup WAN link type the engineer recommend?
A.
LTE
B.
802.16 WiMAX
C.

LTE
Which feature is required for graceful restart to recover from a processor failure?
A.
Cisco Express Forwarding
B.
Virtual Switch System
C.
Stateful Switchover
D.
Bidirectional Forwarding Detection
Stateful Switchover
Explanation:
https://archive.nanog.org/meetings/nanog42/presentations/Weissner_SSO.pdf
The Stateful Switchover (SSO) feature works with Nonstop Forwarding (NSF) in Cisco
software to minimize the amount of time a network is unavailable to its users following a
switchover. The primary objective of SSO is to improve the availability of networks
constructed with Cisco routers
An engineer must design a solution to provide backup connectivity between two sites. The
engineer plans to use an Internet connection but company policy requires the connection to
be encrypted. Additionally, there are several applications that utilize multicast to deliver
video streams between the sites. Which technology should the design include?
A.
GRE over IPsec
B.
IPsec direct encapsulation
C.
GETVPN
D.
DMVPN
GRE over IPsec
Which common issue causes intermittent DMVPN tunnel flaps?
A.
a routing neighbor reachability issue
B.
a suboptimal routing table
C.
interface bandwidth congestion
D.
that the GRE tunnel to hub router is not encrypted
a routing neighbor reachability issue
