• Question 173:

  A mod-size service provider uses L2VPN as its standard for connectivity between offices. A small company wants the service provider to connect the company's two sites across the service provider core. To meet service requirements, the service provider must extend the layer 2 domain between the company's two locations.

  Which configuration must the engineer apply to implement an attachment circuit between the two sites using a VLAN tag of 12?

  A. interface TenGigE0/0/0/1.0 l2transportencapsulation dot1q 12
  B. interface TenGigE0/0/0/1.0 l2transportencapsulation dot1q 12rewrite ingress tag pop 13
  C. interface TenGigE0/0/0/1.0 l2transportencapsulation dot1q 12rewrite ingress tag push dot1q 21 symmetric
  D. interface TenGigE0/0/0/1.0 l2transportencapsulation dot1q 12rewrite ingress tag translate 1-to-1 dot1q 2
  C. interface TenGigE0/0/0/1.0 l2transportencapsulation dot1q 12rewrite ingress tag push dot1q 21 symmetric

  ---

  Explanation

  The correct configuration for extending the layer 2 domain between the company's two locations involves setting up the interface with L2 transport, specifying the encapsulation method as dot1q with the VLAN tag of 12, and applying the appropriate rewrite ingress tag rules. This setup ensures that the VLAN tag is preserved across the service provider's core, maintaining the layer 2 domain continuity.

• Question 176:

  Refer to the exhibit.

  An engineer working for a private telecommunication company with an employee Id: 4065:96:080 upgrades the WAN link between routers ASBR-101 and ASBR- 201 to 1Gb by Installing a new physical connection between the Gi3 Interfaces.

  

  Which BGP attribute must the engineer configure on ASBR-201 so that the existing WAN link on Gi2 Is maintained as a backup?

  

  A. Option A
  B. Option B
  C. Option C
  D. Option D
  A. Option A

• Question 177:

  What is the primary purpose of containers in a service-provider virtualization environment?

  A. to simplify the integration of various hardware components
  B. to enable secure communication between individual network devices
  C. to provide an isolated environment for applications and services
  D. to improve the redundancy of network components
  C. to provide an isolated environment for applications and services

• Question 178:

  You are writing an RPL script to accept routes only from certain autonomous systems. Consider this code:

  RP/0/RP0/CPU0:router(config-rpl)# if as-path in (ios-regex `.*77$') RP/0/RP0/CPU0:router(config-rpl-if)# pass RP/0/RP0/CPU0:router(config-rpl-if)# endif

  If you apply this code to BGP filters, which effect does the code have on your router?

  A. denies routes from AS 7070
  B. allows routes from AS 7077
  C. denies routes from AS 7007
  D. allows routes from AS 770
  B. allows routes from AS 7077

  ---

  Explanation

  The RPL script in the image is used to filter BGP routes based on the AS path. The script includes a condition that checks if the AS path contains `7077' using a regular expression (ios-regex `777$'). If this condition is met, the route is passed; otherwise, it would be denied by default. Therefore, this script allows routes from AS 7077 and denies others.

• Question 179:

  A network engineer is configuring a BGP route policy for the SUBNET prefix set. Matching traffic must be dropped, and other traffic must have its MED value set to 400 and community 4:400 added to the route. Which configuration must an engineer apply?

  A. router-policy CISCOif destination in SUBNET thendropelseset med 400set community (4:400) additiveendifend-policyend

• Question 180:

  Which two uses of the YANG data modeling language are true? (Choose two.)

  A. It can be used to model the configuration used by NETCONF operations.
  B. It can be used to access a device by HTTP.
  C. It can be used to replace the OSI model for troubleshooting.
  D. It can be used to shape state data of network elements.
  E. It can be used to replace RESTCONF as a mechanism to install and manipulate configuration.
  A. It can be used to model the configuration used by NETCONF operations.
  D. It can be used to shape state data of network elements.

  ---

  Explanation

  YANG (Yet Another Next Generation) is a data modeling language used primarily for the configuration and state data of network elements. It is closely associated with the NETCONF (Network Configuration Protocol) for which it models configuration data. YANG provides schemas that define how data is structured and transported by NETCONF operations. It also shapes the state data of network elements, allowing for a standardized format for representing the operational state of devices. References: YANG is defined in RFCs such as RFC 6020 and RFC 7950, which outline its role in NETCONF operations and its capabilities in modeling both configuration and state data.
