NEW QUESTION # 43
Refer to the exhibit.

EIGRP has been configured on all links. The spoke nodes have been configured as EIGRP stubs, and the WAN links to R3 have higher bandwidth and lower delay than the links to R4. When a link failure occurs at the R1-R2 link, what happens to traffic on R1 that is destined for a subnet attached to R2?

A. R1 load-balances across the paths through R3 and R4 to reach R2
B. R1 forwards the traffic to R3 in order to reach R2
C. R1 forwards the traffic to R3, but R3 drops the traffic
D. R1 has no route to R2 and drops the traffic

Answer: D

Explanation:
Explanation
The EIGRP stub routing feature will prevent the remote device from advertising core routes back to the distribution devices. Routes learned by the remote device from Distribution 1 will not be advertised to Distribution 2. Therefore, Distribution 2 will not use the remote device as a transit for traffic destined to the network core

Answer: A

NEW QUESTION # 47
An engineer must connect a new remote site to an existing OSPF network. The new site consists of two low-end routers, one for WAN, and one for LAN. There is no demand for traffic to pass through this area. Which area type does the engineer choose to provide minimal router resources utilization, while still allowing for full connectivity to the rest of the network?

A. stubby area
B. not so stubby
C. totally not so stubby
D. totally stubby area

Answer: D

Explanation:
LSA type1 + type2 + Defaut required to minimise Router resources utilization -> total stub area.

NEW QUESTION # 49
Refer to the exhibit.

An architect must design an IGP solution for an enterprise customer. The design must support:
Physical link flaps should have minimal impact.
Access routers should converge quickly after a link failure.
Which two ISIS solutions should the architect include in the design? (Choose two.)

A. Configure all access and aggregate routers to establish Level 1 / Level 2 adjacencies across the network.
B. Use BGP to IS-IS redistribution to advertise all Internet routes in the Level 1 area.
C. Configure access routers to establish a Level 1 adjacency and aggregate routers to establish a Level 1 /
D. Reduce SPF and PRC intervals to improve convergence time.
E. Advertise the IS-IS interface and loopback IP address toward the Internet and data center.

Answer: A,D

Explanation:
Level 2 adjacency.

NEW QUESTION # 50
A client is moving to Model-Driven Telemetry and requires periodic updates. What must the network architect consider with this design?

NEW QUESTION # 51
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. GETVPN
B. GRE over IPsec
C. DMVPN
D. IPsec direct encapsulation

Answer: B

NEW QUESTION # 52
A company needs to increase access port capacity on one floor of a building. They want to leverage the existing catalyst access switch. There is no problem with uplink bandwidth capacity.
However, no additional uplinks can be added because no ports are available on the distribution switches. Which solution must the company choose to provide additional access ports?

A. Etherchannel
B. Stackwise
C. VDC
D. VSS

Answer: B

Explanation:
The company should choose Cisco StackWise technology to provide additional access ports.
StackWise allows multiple Cisco Catalyst switches to be interconnected, creating a single logical switch with increased port capacity. This solution helps to expand the access layer without needing additional uplinks to the distribution switches. StackWise technology simplifies management and increases the resiliency of the network.
