NEW QUESTION # 150
An architect must create a QoS solution for a customer to ensure that a 40 Mbps Internet connection is shared between four subnets based on these requirements:
* Each subnet must receive no less than 10 Mbps of download bandwidth during peak traffic times.
* A subnet can use up to 40 Mbps during nonpeak traffic times if the other subnets are idle.
* Download traffic must never experience a delay.
Which solution must the architect choose?
- A. bandwidth percentage and policing
- B. shaping and policing
- C. bandwidth percentage and rate-limiting
- D. rate-limiting and shaping
Answer: A
Explanation:
"Download traffic must never experience a delay."
This means we shouldn't be using Shaping at any point (since that puts packets into a buffer and sends them out later on when congestion has been reduced) Also: "Rate-limiting" is a bigger term and under it we have 2 things: "Policing" and "Shaping"

Refer to the exhibit. All routers currently reside in OSPF area 0. The network manager recently used R1 and R2 as aggregation routers for remote branch locations and R3 and R4 for aggregation routers for remote office locations. The network has since been suffering from outages, which are causing frequent SPF runs. To enhance stability and introduce areas to the OSPF network with the minimal number of ABRs possible, which two solutions should the network manager recommend? (Choose two.)
- A. a new OSPF area for R3 and R4 connections, with R5 and R6 as ABRs
- B. a new OSPF area for R1, R2, R3, and R4 connections, with R1, R2, R3, and R4 as ABRs
- C. a new OSPF area for R1 and R2 connections, with R1 and R2 as ABRs
- D. a new OSPF area for R3 and R4 connections, with R3 and R4 as ABRs

Explanation:
NEW QUESTION # 156
Refer to the exhibit. An engineer is planning an IPv4 to IPv6 migration solution for a customer.
The routers in the network can support IPv4 and IPv6, except for the DWDM routers. The DWDM routers provide a Layer 2 link in which the routers peer directly with each other across a DWDM circuit. The circuit also provides connectivity between the mail servers. Which IPv6 migration technique must the engineer deploy?
- A. 6to4
- B. 6rd
- C. dual-stack
- D. ISATAP
Answer: C
NEW QUESTION # 157
Which two steps can be taken to improve convergence in an OSPF network? (Choose two.)
- A. Merge all the areas into one backbone area
- B. Tune OSPF parameters
- C. Span the same IP network across multiple areas.
- D. Make all non-backbone areas stub areas
- E. Use Bidirectional Forwarding Detection
Answer: B,E
Explanation:
Network convergence is the time that is needed for the network to respond to events.
One of the significant factors in routing convergence is the detection of link or node failure (events).
This is where BFD comes in to play.
OSPF Timers
The default OSPF LSA propagation timers are quite conservative. Lowering the values of the timers that control OSPF LSA generation can significantly improve OSPF convergence times

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).
