Q1. RAG DROP
Answer:
Q2. When configuring Cisco IOS route maps, which command allows the route map processing to jump to another statement instead of exiting?
A. jump
B. next
C. set
D. continue
E. goto
Answer: D
Explanation:
Match Operations With Continue Clauses
If a match clause does not exist in the route-map entry but a continue clause does, the continue clause will be automatically executed and go to the specified route-map entry. If a match clause exists in a route-map entry, the continue clause is executed only when a successful match occurs. When a successful match occurs and a continue clause exists, the route map executes the set clauses and then goes to the specified route-map entry. If the next route map contains a continue clause, the route map will execute the continue clause if a successful match occurs. If a continue clause does not exist in the next route map, the route map will be evaluated normally. If a continue clause exists in the next route map but a match does not occur, the route map will not continue and will “fall through” to the next sequence number if one exists.
Set Operations With Continue Clauses
Set clauses are saved during the match clause evaluation process and executed after the route-map evaluation is completed. The set clauses are evaluated and executed in the order in which they were configured. Set clauses are only executed after a successful match occurs, unless the route map does not contain a match clause. The continue statement proceeds to the specified route-map entry only after configured set actions are performed. If a set action occurs in the first route map and then the same set action occurs again, with a different value, in a subsequent route map entry, the last set action may override any previous set actions that were configured with the same set command unless the set command permits more than one value. For example, the set as-path pretend command permits more than one autonomous system number to be configured.

Q7. Which statement best describes the function of a BGP af-group?
A. Use templates in different neighbors so it makes the BGP implementation easier.
B. Group different address family neighbors inside BGP.
C. Create a group of neighbors that can inherit address family configuration inside BGP.

B. only purchases transit from other networks to reach the Internet
C. purchases transit and pays settlements to other service providers
D. uses strict route filtering to allow only customer and local routes to be sent to upstream providers
E. receives a full Internet routing table via BGP from its upstream provider, which it can use for load-balancing traffic

Q10. Refer to the exhibit.
Routers B and C in transit AS 200 are the exit points toward AS 100 and AS 300. Router B is running Cisco IOS XR and Router C IOS XE. Internally, AS 200 runs OPSF only for internal routing. Which two methods can an engineer use to ensure proper reachability between AS 100 and AS 300 for the needed routes? (Choose two.)
A. Router B: router ospf 200 redistribute bgp 200 tag 20 router bgp 200 address-family ipv4 unicast redistribute ospf 200 metric-type 2
