• Question 212:

  Which Cisco software OS uses monolithic architecture?

  A. NX-OS
  B. IOS XE
  C. IOS XR
  D. IOS
  D. IOS

  ---

  Explanation

  Cisco Internetwork Operating System (IOS) is the software used on most Cisco Systems routers and current Cisco network switches. IOS is a package of routing, switching, internetworking and telecommunications functions integrated into a multitasking operating system. IOS uses a monolithic architecture, meaning that all processes run in a single address space, making it a single-image system.

• Question 213:

  Which CLI mode must be used to configure the BGP keychain in Cisco IOS XR Software?

  A. routing configuration mode
  B. BGP neighbor configuration mode
  C. global configuration mode
  D. BGP address-family configuration mode
  B. BGP neighbor configuration mode

  Explanation

• Question 214:

  Why do packet loops occur during the configuration of BIDIR-PIM?

  A. The network does not support BIDIR-PIM.
  B. The network is partially upgraded to support BIDIR-PIM.
  C. The router has not been configured to advertise itself.
  D. No interface for carrying traffic for multicast groups has been configured.
  B. The network is partially upgraded to support BIDIR-PIM.

• Question 215:

  Refer to the exhibit.

  

  You are configuring an administrative domain in the given multi-vendor environment with PIM-SM.

  Which feature can you implement so that devices can dynamically learn the RP?

  A. BSR
  B. BIDIP-PIM
  C. Auto-RP
  D. SSM
  A. BSR

  ---

  Explanation

  In a multi-vendor environment with PIM-SM, the Bootstrap Router (BSR) mechanism is used for devices to dynamically learn the Rendezvous Point (RP). BSR is a protocol feature that automates the dissemination of RP information in a PIM domain. This feature allows routers to automatically discover the RP set in use, which simplifies configuration and management compared to static RP configurations or Auto- RP.

• Question 216:

  SIMULATION

  

  Guidelines

  This is a lab item in which tasks will be performed on virtual devices.

  1. Refer to the Tasks tab to view the tasks for this lab item.

  2. Refer to the Topology tab to access the device console(s) and perform the tasks.

  3. Console access is available for all required devices by clicking the device icon or using the tab(s) above the console window.

  4. All necessary preconfigurations have been applied.

  5. Do not change the enable password or hostname for any device.

  6. Save your configurations to NVRAM before moving to the next item.

  7. Click Next at the bottom of the screen to submit this lab and move to the next question.

  8. When Next is clicked, the lab closes and cannot be reopened.

  Topology

  

  Tasks

  Configure and verify the OSPF neighbor adjacency between R1 and R2 in OSPF area 0 according to the topology to achieve these goals:

  1. Configure OSPF cost to 15 on R1 and R2.

  2. Redistribute all the static routes defined in R1 and R2 to the OSPF routing protocol.

  3. Set the OSPF hello interval to 5 and the OSPF dead interval to 10 between R1 and R2.

  A. See explanation below.
  B. PlaceHolder
  C. PlaceHolder
  D. PlaceHolder
  A. See explanation below.

  ---

  Explanation

  R1

  router ospf 10 redistribute static int et0/0 ip ospf hello-interval 5 ip ospf dead-interval 10 ip ospf cost 15 ip ospf 10 area 0 copy run start

  R2

  router ospf 10 redistribute static int et0/0 ip ospf hello-interval 5 ip ospf dead-interval 10 ip ospf cost 15 ip ospf 10 area 0 copy run start

• Question 217:

  Which feature describes the weight parameter for BGP path selection?

  A. Its value is local to the router
  B. Its value is set either locally or globally.
  C. Its default value is 0.
  D. Its value is global to the router.
  A. Its value is local to the router

  ---

  Explanation

  The weight parameter in BGP (Border Gateway Protocol) is a Cisco-specific attribute that is local to the router on which it is configured. It is used to prefer one path over another when multiple paths to the same destination are available. The weight is not advertised to other routers, making it a local parameter.

• Question 218:

  A customer of an ISP requests support to setup a BGP routing policy. Which BGP attribute should be configured to choose specific BGP speakers as preferred points for the customer AS?

  A. lowest multi-exit discriminator
  B. highest local preference outbound
  C. lowest local preference inbound
  D. highest local preference inbound
  D. highest local preference inbound

  Explanation

• Question 219:

  Which router or router combination is used to calculate the MPLS traffic engineering tunnel path?

  A. head-end router and tail-end router
  B. middle-point router
  C. head-end router
  D. tail-end router
  C. head-end router

  ---

  Explanation

• Question 220:

  Refer to the exhibit.

  

  A host connected to R3 must connect with a server on R1 that provides critical, time-sensitive data. Traffic between the host and server must always be given bandwidth to traverse the links when they are congested, with other traffic being dropped. How must the network engineer implement a QoS strategy with classification to ensure that the traffic is given the appropriate bandwidth?

  A. Implement policing to rate-limit noncritical traffic that exceeds designated thresholds.
  B. Implement traffic shaping to delay noncritical traffic when the link is congested.
  C. Implement strict priority to guarantee bandwidth for the server traffic.
  D. Implement FIFO to guarantee that the server traffic is sent first while other traffic is queued.
  C. Implement strict priority to guarantee bandwidth for the server traffic.

  ---

  Explanation

  To ensure that critical, time-sensitive data from the server on R1 to the host on R3 is always prioritized, especially during congestion, the network engineer should implement a Quality of Service (QoS) strategy that uses strict priority queuing. This QoS mechanism ensures that traffic marked as high priority is transmitted first, while other traffic may be queued or dropped if necessary. Strict priority queuing is designed for scenarios exactly like this, where certain traffic must be guaranteed bandwidth to meet time-sensitive requirements. References: For more detailed information on QoS strategies and classification, refer to the Implementing and Operating Cisco Service Provider Network Core Technologies (SPCOR) course materials, specifically the sections discussing QoS mechanisms and their implementation in service provider networks. Additionally, Cisco's official documentation on QoS provides comprehensive guidelines on configuring and applying strict priority queuing to ensure bandwidth for critical traffic.
