Which two are advantages of static routing when compared to dynamic routing? (Choose two.)

Question

Options

• AConfiguration complexity decreases as network size increases.
• BSecurity increases because only the network administrator may change the routing table.
• CRoute summarization is computed automatically by the router.
• DRouting tables adapt automatically to topology changes.
• EAn efficient algorithm is used to build routing tables, using automatic updates.
• FRouting updates are automatically sent to neighbors.
• GRouting traffic load is reduced when used in stub network links.

• B
  88% (22)
• D
  8% (2)
• F
  4% (1)

Explanation

Static routing has two key advantages over dynamic routing: (B) Security is improved because only a network administrator can manually add or modify routes - there is no automatic update mechanism that an attacker could exploit or that could introduce unwanted route changes. (G) On stub network links (networks with only one path in or out), static routes eliminate the overhead of routing protocol traffic (hellos, updates, acknowledgments), reducing bandwidth consumption. The other choices describe advantages of dynamic routing: automatic topology adaptation (D), automatic summarization (C), efficient algorithms and auto-updates (E), and automatic neighbor updates (F). Choice A is incorrect because static routing complexity increases (not decreases) as the network grows.
