Question 1 of 134
Which two statements describe aggregate routes? (Choose two.)
    Correct Answer: B, C

    Aggregate routes help in summarizing multiple routes into a single route entry, which helps in reducing the size of routing tables. By combining several specific routes into one aggregate route, internal routing instabilities are hidden from external peers. This means that routing issues within a network do not propagate to external peers, promoting stability. Therefore, the correct answers are that internal routing instabilities can be hidden from external peers and groups of routes are combined into a single route entry.

Question 2 of 134
You are configuring a new BGP service to your service provider. You want to ensure that BGP is fully established and has all the routes in the route table before allowing traffic to transit the router.
Which feature achieves this requirement?
    Correct Answer: D

    To achieve the requirement of ensuring that BGP is fully established and has all the routes in the route table before allowing traffic to transit the router, the IS-IS overload bit is the correct feature. This feature can temporarily prevent the router from being used for transit traffic until it has fully synchronized its BGP routes. It tells other routers in the network to avoid using this router for transit traffic until it is ready, thereby ensuring the desired state is met before traffic is allowed to pass through.
