QUESTION 1:
Refer to the exhibit. An engineer must design an automatic failover solution. The solution should allow HSRP to detect a WAN 1 failure and initiate an automatic failover, making router R2 the active HSRP router. Which two solutions should the engineer choose? (Choose two.)
A. Implement Enhanced Object Tracking on roster R1
B. use a floating static route
C. Implement IP SLA on router R1
D. Implement PBR on router R1
E. use IP source routing
Correct Answer: AC
QUESTION 2:
An engineer must design a VPN solution for a company that has multiple branches connecting to the main office. What are two advantages of using DMVPN instead of IPsec tunnels to accomplish this task? (Choose two.)
A. support for AES 256-bit encryption
B. greater scalability
C. support for anycast gateway
D. lower-traffic overhead
E. dynamic spoke-to-spoke tunnels
Correct Answer: BE
QUESTION 3:
Refer to the exhibit. An engineer is designing an OSPF network for a client. Requirements dictate that the routers in Area 1 should receive all routers belonging to the network, including EIGRP, except the ones originated in the RIP domain. Which action should the engineer take?
A. Make area 1 an NSSA.
B. Make area 1 a stub.
C. Make area 1 a standard OSPF area.
D. Make the area 1 router part of area 0.
Correct Answer: A
QUESTION 4:
Which NETCONF operation creates filtering that is specific to the session notifications?
A.
B.
C.
D.
Correct Answer: A
QUESTION 5:
A large chain of stores currently uses MPLS-based T1 lines to connect their stores to their data center. An architect must design a new solution to improve availability and reduce costs while keeping these considerations in mind:
1.
The company uses multicast to deliver training to the stores.
2.
The company uses dynamic routing protocols and has implemented QoS.
3.
To simplify deployments, tunnels should be created dynamically on the hub when additional stores open.
Which solution should be included in this design?
A. VPLS
B. GET VPN
C. DMVPN
D. IPsec
Correct Answer: C
QUESTION 6:
An organization is designing a detailed QoS plan that limits bandwidth to specific rates. Which two parameters are supported by the traffic policing feature? (Choose two.)
A. violating
B. marking
C. shaping
D. bursting
E. conforming
Correct Answer: BC
QUESTION 7:
An engineer is creating a design to enable IPv6 to run on an existing IPv4 IS-IS network. The IPv4 and IPv6 topologies will match exactly, and the engineer plans to use the same IS-IS router levels for each protocol per interface. Which IS-IS design is required?
A. multi-topology without enabling transition feature
B. multi-topology with transition feature enabled
C. single topology without enabling transition feature
D. single topology with transition feature enabled
Correct Answer: B
QUESTION 8:
Which nonproprietary mechanism can be used to automate rendezvous point distribution in a large PIM domain?
A. Embedded RP
B. BSR
C. Auto-RP
D. Static RP
Correct Answer: B
QUESTION 9:
Which method does Cisco SD-WAN use to avoid fragmentation issues?
A. PMTUD is used.
B. Access circuits are configured with 1600 byte MTU settings.
C. Jumbo frames are enabled.
D. Traffic is marked with the DF bit set.
Correct Answer: A
QUESTION 10:
Refer to the exhibit.
A network engineer must improve the current IS-IS environment. The Catalyst switch is equipped with dual supervisors.
Each time a stateful switchover occurs, the network experiences unnecessary route recomputation. Which solution addresses this issue if the upstream router does not understand graceful restart messaging?
A. Enable IS-IS remote LFA FRR on both devices.
B. Enable NSR on the switch.
C. Enable NSF on the switch.
D. Configure ISIS aggressive timers on both devices.
Correct Answer: C
QUESTION 11:
An engineer must design a multicast network for a financial application. Most of the multicast sources also receive multicast traffic (many-to-many deployment model). To better scale routing tables, the design must not use source trees.
Which multicast protocol satisfies these requirements?
A. PIM-SSM
B. PIM-SM
C. MSDP
D. BIDIR-PIM
Correct Answer: D
Bidir-PIM is designed to be used for many-to-many applications within individual PIM domains. Multicast groups in bidirectional PIM mode can scale to an arbitrary number of sources without incurring overhead due to the number of sources.
QUESTION 12:
An engineer is working with NETCONF and Cisco NX-OS-based devices. The engineer needs a YANG model that supports a specific feature relevant only to Cisco NX-OS. Which model must the engineer choose?
A. Native
B. IEEE
C. OpenConfig
D. IETF
Correct Answer: D
QUESTION 13:
How is the sub-second failure of a transport link detected in a Cisco SD-WAN network?
A. Hellos are sent between the WAN Edge routers and the vSmart controller.
B. BFD runs on the IPsec tunnels between WAN Edge routers.
C. BGP is used between WAN Edge routers and the vSmart controller.
D. Link state change messages are sent between vSmart controllers.
Correct Answer: B
