Zorluk: KolayRouting Concepts and Dynamic Routing Protocols

A network administrator is replacing static routes with a dynamic routing protocol across an enterprise network. Which TWO of the following are key operational features provided by dynamic routing protocols? (Select TWO.)

  1. Automatically discover reachable remote subnets through neighbor information exchangesCevap
  2. Automatically recalculate alternate paths when a active network link failsCevap
  3. C
    Eliminate the requirement for Layer 3 network layer addresses on routing interfaces
  4. D
    Translate multiple private internal IP addresses into a single public IP address

Cevap

Dynamic routing protocols automatically discover remote networks by communicating with neighboring routers and recalculate valid backup paths when a link failure occurs.
Dynamic routing protocols automatically discover remote subnets by exchanging network state and path metrics with neighboring routers. In addition, when network topology changes or a link fails, dynamic routing protocols recalculate paths and update routing tables without manual intervention.

Adım Adım Çözüm

1
Identify the primary purpose of dynamic routing protocols
Dynamic routing protocols automate route discovery and topology maintenance across routers.
Static routing requires manual route entry, while dynamic protocols continuously update routing tables based on network state.
2
Evaluate the choices against dynamic routing protocol functionality
Discovering remote subnets from neighbor routers and dynamically re-routing traffic around failed links are core features of dynamic routing protocols.
Protocols like OSPF, EIGRP, and RIP continuously share state and metric information to update network topology maps.
3
Distinguish routing from addressing and NAT services
Layer 3 addressing remains essential for routing interfaces, and address translation is handled by PAT/NAT rather than dynamic routing protocols.
Routing protocols direct traffic between subnets using Layer 3 IP headers; they do not remove IP addressing requirements or perform NAT overload functions.
