💡 Hint

Common Mistakes

Thinking static routing uses manual protocols to adjust automatically.

Confusing switching with routing.

Static routing does NOT adjust automatically. Dynamic routing uses protocols to adjust routes.

4fill in blank

Fill both blanks to complete the comparison between static and dynamic routing.

Computer Networks

Static routing is [1] and requires [2] configuration.

💡 Hint

Common Mistakes

Mixing up manual and automatic.

Underestimating the complexity of static routing setup.

Static routing is manual and requires complex configuration because each route must be set by hand.

5fill in blank

Fill all three blanks to complete the dictionary comprehension about routing types.

Computer Networks

routing_info = { [1]: [2] for [3] in ['static', 'dynamic'] }

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using the same name for key and loop variable causing confusion.

Choosing variable names that don't match the context.

This comprehension creates a dictionary where keys are route types and values describe the type.

Practice

1. What is the main difference between static routing and dynamic routing?

easy

A. Static routing changes paths automatically, dynamic routing uses fixed paths.

B. Static routing uses fixed paths set manually, dynamic routing finds paths automatically.

C. Static routing is only for wireless networks, dynamic routing is for wired networks.

D. Static routing requires no configuration, dynamic routing requires manual setup.

Solution

1. Step 1: Understand static routing

   Static routing means the network paths are set manually by a person and do not change unless manually updated.

2. Step 2: Understand dynamic routing

   Dynamic routing uses protocols that automatically find and update the best paths as the network changes.

3. Final Answer:

   Static routing uses fixed paths set manually, dynamic routing finds paths automatically. -> Option B

4. Quick Check:

   Static = manual paths, Dynamic = automatic paths [OK]

Hint: Static = manual setup, dynamic = automatic updates [OK]

Common Mistakes:

• Confusing which routing type updates paths automatically
• Thinking static routing changes paths by itself
• Assuming static routing needs no configuration

2. Which of the following is the correct way to describe static routing?

easy

A. Routing paths are based on user traffic patterns.

B. Routing paths are discovered and updated automatically.

C. Routing paths are randomly assigned by the router.

D. Routing paths are manually configured and do not change unless updated.

Solution

1. Step 1: Identify static routing characteristics

   Static routing requires manual configuration of paths and these paths remain fixed unless changed by an administrator.

2. Step 2: Eliminate incorrect options

   Options describing automatic discovery, random assignment, or traffic-based paths do not apply to static routing.

3. Final Answer:

   Routing paths are manually configured and do not change unless updated. -> Option D

4. Quick Check:

   Static = manual and fixed paths [OK]

Hint: Static means manual setup, no automatic changes [OK]

Common Mistakes:

• Thinking static routing updates paths automatically
• Confusing static with dynamic routing
• Assuming static routing is random

3. Consider a network where a router uses dynamic routing protocols. What will happen if a link fails?

medium

A. The router will automatically find a new path to the destination.

B. The router will keep sending data through the failed link.

C. The router will shut down until the link is fixed.

D. The router will require manual reconfiguration to find a new path.

Solution

1. Step 1: Understand dynamic routing behavior on failure

   Dynamic routing protocols detect link failures and automatically update routing tables to find alternative paths.

2. Step 2: Analyze each option

   The router will keep sending data through the failed link. is incorrect because dynamic routing avoids failed links. The router will shut down until the link is fixed. is wrong; routers do not shut down. The router will require manual reconfiguration to find a new path. describes static routing behavior.

3. Final Answer:

   The router will automatically find a new path to the destination. -> Option A

4. Quick Check:

   Dynamic routing adapts automatically to failures [OK]

Hint: Dynamic routing adapts automatically to network changes [OK]

Common Mistakes:

• Assuming router stops working on link failure
• Confusing static routing behavior with dynamic
• Thinking manual intervention is always needed

4. A network administrator set up static routes but notices that some routes are not working after a network change. What is the likely problem?

medium

A. Static routes do not update automatically after network changes.

B. Dynamic routing protocols are interfering with static routes.

C. Static routes always update automatically, so the problem is hardware.

D. The router does not support static routing.

Solution

1. Step 1: Understand static routing limitations

   Static routes are fixed and do not change unless manually updated by the administrator.

2. Step 2: Identify cause of route failure

   After network changes, static routes may become invalid because they do not update automatically, causing routing failures.

3. Final Answer:

   Static routes do not update automatically after network changes. -> Option A

4. Quick Check:

   Static routes need manual updates after changes [OK]

Hint: Static routes stay fixed; update manually after changes [OK]

Common Mistakes:

• Assuming static routes update automatically
• Blaming hardware without checking routing setup
• Confusing static and dynamic routing behavior

5. In a large company with many branch offices that frequently change network connections, which routing method is best and why?

hard

A. Static routing, because it is simple and requires no updates.

B. Dynamic routing, because it requires manual configuration for each change.

C. Dynamic routing, because it automatically adapts to network changes.

D. Static routing, because it uses less CPU power on routers.

Solution

1. Step 1: Consider network size and change frequency

   Large networks with frequent changes need routing that adapts quickly without manual updates.

2. Step 2: Compare static and dynamic routing suitability

   Static routing is manual and not practical for frequent changes. Dynamic routing automatically updates paths, making it suitable for large, changing networks.

3. Final Answer:

   Dynamic routing, because it automatically adapts to network changes. -> Option C

4. Quick Check:

   Large, changing networks need dynamic routing [OK]

Hint: Use dynamic routing for large, changing networks [OK]

Common Mistakes:

• Choosing static routing for large, dynamic networks
• Thinking dynamic routing needs manual updates
• Ignoring network size and change frequency
