Exhibit:

 

 

BGP is flapping after the Copp policy is applied. What are the two solutions to fix the issue? (Choose two)


A.

Configure BGP in the COPP-CRITICAL-7600 ACL


B.

Configure a higher value for CIR under the default class to allow more packets during peak traffic


C.

Configure a higher value for CIR under the class COPP-CRITICAL-7600


D.

Configure a three-color policer instead of two-color policer under class COPPCRITICAL- 7600


E.

Configure IP CEF to CoPP policy and BGP to work





A.
  

Configure BGP in the COPP-CRITICAL-7600 ACL



B.
  

Configure a higher value for CIR under the default class to allow more packets during peak traffic



Explanation: The policy-map COPP-7600 only rate-limit HTTP & HTTPS traffic (based on the ACL conditions) so any BGP packets will be processed in the class “class-default”, which drops exceeded BGP packets. Therefore we have two ways to solve this problem:
+ Add BGP to the ACL with the statement “permit tcp any any eq bgp”
+ Configure higher value for CIR in default class as 2Mbps is too low for web traffic (http & https)

Refer to the exhibit.

Which statement about R1 is true?

 


A.

OSPF redistributes RIP routes only if they have a tag of one.


B.

RIP learned routes are distributed to OSPF with a tag value of one.


C.

R1 adds one to the metric for RIP learned routes before redistributing to OSPF.


D.

RIP routes are redistributed to OSPF without any changes.





B.
  

RIP learned routes are distributed to OSPF with a tag value of one.



Drag and drop the SNMP attributes in Cisco IOS devices from the left onto the correct SNMPv2c or SNMPV3 categories on the right.






Drag and drop the operations from the left onto the locations where the operations are performed on the right.






Refer to the exhibit.

A network engineer for AS64512 must remove the inbound and outbound traffic from link A during maintenance without closing the BGP session so that there ............ a backup link over link A toward the ASN. Which BGP configuration on R1 accomplishes this goal?


A.

Option A


B.

Option B


C.

Option C


D.

Option D





C.
  

Option C



Drag and drop the MPLS VPN concepts from the left onto the correct descriptions on the right.






Refer to the exhibit.

An engineer is monitoring reachability of the configured default routes to ISP1 and ISP2. The default route from ISP1 is preferred if available. How is this issue resolved?

 


A.

Use the icmp-echo command to track both default routes


B.

Use the same AD for both default routes


C.

Start IP SLA by matching numbers for track and ip sla commands


D.

Start IP SLA by defining frequency and scheduling it





D.
  

Start IP SLA by defining frequency and scheduling it



An engineer configured a company’s multiple area OSPF head office router and Site A cisco routers with VRF lite. Each site router is connected to a PE router of an MPLS backbone.

After finishing both site router configurations, none of the LSA 3,4 5, and 7 are installed at Site A router. Which configuration resolves this issue?


A.

configure capability vrf-lite on Site A and its connected PE router under router ospf 1 vrf abc


B.

configure capability vrf-lite on Head Office and its connected PE router under router ospf 1 vrf abc


C.

configure capability vrf-lite on both PE routers connected to Head Office and Site A routers under routtr ospf 1 vrf abc


D.

configure capability vrf-lite on Head Office and Site A routers under router ospf 1 vrf abc





C.
  

configure capability vrf-lite on both PE routers connected to Head Office and Site A routers under routtr ospf 1 vrf abc



Drag and Drop the IPv6 First-Hop Security features from the left onto the definitions on the right.






Refer to the exhibit.

An engineer is trying to redistribute OSPF to BGP, but not all of the routes are redistributed. What is the reason for this issue?


A.

By default, only internal routes and external type 1 routes are redistributed into BGP


B.

Only classful networks are redistributed from OSPF to BGP


C.

BGP convergence is slow, so the route will eventually be present in the BGP table


D.

By default, only internal OSPF routes are redistributed into BGP





D.
  

By default, only internal OSPF routes are redistributed into BGP
