NEW QUESTION # 160
An engineer is designing a multicast network for a company specializing in VoD content. Receivers are across the Internet, and for performance reasons, the multicast framework close to the receivers within each AS.

* Users will be migrated in a phase-by-phase approach.
Which migration solution must the architect choose?

NEW QUESTION # 162
Refer to the exhibit. Area 10 is a regular OSPF area and networks 10.1.1.0/24 and 172.16.1.0/24 are internal. Which design provides optimal routing between both networks when the link between routers C and E fails?
- A. Move the link between routers C and D to area 10.
- B. Make area 10 a not-so-stubby area.
- C. Create a tunnel between routers E and F in area 10.
- D. Create an OSPF virtual link between routers E and F.
Answer: A
NEW QUESTION # 163
Which switch feature prevents traffic on a LAN from being overwhelmed by continuous multicast or broadcast traffic?
- A. port security
- B. VTP pruning
- C. storm control
- D. VLAN trunking
Answer: C
Explanation:
A traffic storm occurs when packets flood the LAN, which creates excessive traffic and degrades network performance. The traffic storm control feature prevents LAN ports from being disrupted by a broadcast, multicast, or unicast traffic storm on physical interfaces from either mistakes in network configurations or from users issuing a DoS attack.

NEW QUESTION # 164
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 has no route to R2 and drops the traffic
- C. R1 forwards the traffic to R3, but R3 drops the traffic
- D. R1 forwards the traffic to R3 in order to reach R2
Answer: D

NEW QUESTION # 166
A branch office has a primary L3VPN MPLS connection back to the main office and an IPSEC VPN tunnel that serves as backup.
Which design ensures that data is sent over the backup connection only if the primary MPLS circuit is down?
- A. Use BGP with the multipath feature enabled to force traffic via the primary path when available.
- B. Use EIGRP to establish a neighbor relationship with the main office via L3VPN MPLS and the IPSEC VPN tunnel.
- C. Use OSPF with a passive-interface command on the backup connection.
- D. Use static routes tied to an IP SLA to prefer the primary path while a floating static route points to the backup connection.
Answer: D
Explanation:
Floating static routes are static routes that are used to provide a backup path to a primary static or dynamic route, in the event of a link failure.
NEW QUESTION # 167
A network engineer must design a multicast solution to prevent the spoofing of multicast streams and ensure efficient bandwidth utilization. The network will be merged with another multicast domain in the future, and the merge must require minimum effort. Which two solutions meet the customer requirements? (Choose two.)
- A. PIM-SM
- B. IGMPv2
- C. MSDP
- D. PIM-SSM
- E. IGMPv3
Answer: A,C
Explanation:
Explanation
https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/ipmulti_pim/configuration/xe-16/imc-pim-xe-16-book/imc-m MSDP is a mechanism to connect multiple PIM-SM domains. The purpose of MSDP is to discover multicast sources in other PIM domains. The main advantage of MSDP is that it reduces the complexity of interconnecting multiple PIM-SM domains by allowing PIM-SM domains to use an interdomain source tree (rather than a common shared tree).

* announce sources joining the group
Which solution supports these requirements?
- A. SSM
- B. PIM-DM
- C. MSDP
- D. PIM-SM
Answer: C

NEW QUESTION # 171
An engineer must design an in-band management solution for a customer with branch sites. The solution must allow remote management of the branch sites using management protocols over an MPLS WAN. Queueing is implemented at the remote sites using these classes:
How must the solution prioritize the management traffic over the WAN?
- A. Mark the traffic with DSCP CS1 and map into Class2 with a minimum bandwidth assigned by reducing the bandwidth available to CIass3.
- B. Mark the traffic with DSCP CS6 and map into Class1 with a minimum bandwidth assigned by reducing the bandwidth available to Class2
- C. Mark the traffic with DSCP CS2 and map into Class2 with a minimum bandwidth assigned by reducing the bandwidth available to Class3
- D. Mark the traffic with DSCP EF and map into Class1 with a minimum bandwidth assigned by reducing the bandwidth available to Class2.
Answer: D
NEW QUESTION # 172
Refer to the exhibit.
Refer to the exhibit. An architect is developing a solution to consolidate networks while retaining device redundancy. The routing protocol for the WAN routers must be open standard, ensure high availability, and provide the fastest convergence time. Which solution must the design include?

- B. both routers running OSPFv2
- C. one router running ISIS and other OSPF v3
- D. one router running OSPFv2 and other OSPF v3
