AWS Direct Connect Resiliency Quiz

1. What is the primary advantage of using a second Direct Connect connection at a different location?

Reduces monthly AWS costs

Protects against location-specific failures

Increases total bandwidth capacity only

Eliminates need for encryption

2. In a resilient Direct Connect setup, how should you configure the BGP community tag?

Use identical tags across all connections

Use different tags to identify traffic sources and control routing policies

Community tags are not supported

Use only on the primary connection

3. What is the primary limitation of using a single Direct Connect connection without redundancy?

Higher latency than VPN

No failover capability; any connection failure causes complete outage

Inability to use VPCs

Maximum bandwidth of 1 Gbps

4. Which scenario requires implementing BGP conditional advertisement in Direct Connect?

Advertising different routes based on connection state

Reducing total route count

Encrypting BGP messages

Limiting VPC associations

5. In Direct Connect, what does connection colocation refer to?

Placing multiple connections at the same AWS location for cost savings

Routing traffic through multiple AWS regions

Sharing bandwidth with other customers

Using private VIFs only

6. What is the benefit of using multiple customer routers in a Direct Connect resiliency architecture?

Eliminates need for AWS redundancy

Provides failover at the customer network edge

Reduces Direct Connect port costs

Increases AWS region availability

7. Which monitoring metric indicates potential Direct Connect connection degradation?

BGP session uptime

Increased packet loss or latency via CloudWatch metrics

VPC flow log size

Security group rule count

8. In Direct Connect resiliency design, what role does AWS Transit Gateway play?

Aggregates multiple Direct Connect connections and simplifies routing

Eliminates need for BGP configuration

Provides automatic encryption

Replaces VPC peering entirely

9. What does the BGP graceful restart mechanism provide in Direct Connect failover scenarios?

Prevents route flapping and packet loss during convergence

Doubles connection bandwidth

Eliminates need for redundant connections

Automatically adjusts VLAN tags

10. Which network design pattern combines Direct Connect with VPN for maximum redundancy?

Active-active Direct Connect with standby VPN

Direct Connect only, no VPN backup

VPN only with Direct Connect monitoring

Dual VPN connections without Direct Connect

11. What is the primary purpose of AWS Direct Connect in enterprise networking?

Establish dedicated network connections to AWS with consistent bandwidth

Replace all internet-based connectivity with VPN tunnels

Provide free data transfer between AWS regions

Eliminate the need for AWS security groups

12. In a resilient Direct Connect architecture, how should BGP timers be configured?

Use default timers for simplicity

Reduce keepalive and hold timers for faster failure detection

Increase hold timer to prevent instability

Disable BGP timers for automatic adjustment

13. Which Direct Connect feature enables traffic segregation across multiple connections?

VLAN tagging on virtual interfaces

Route table manipulation

Security group filtering

Network ACL restrictions

14. What is the typical recovery time objective (RTO) for Direct Connect failover using BGP?

Less than 1 minute

30 seconds to 2 minutes

5 to 10 minutes

Manual intervention required

15. In a Direct Connect resiliency setup, what does BGP AS path prepending accomplish?

Increases bandwidth allocation

Influences traffic flow by making certain paths less preferred

Encrypts all BGP advertisements

Eliminates need for redundant connections

16. Which AWS service monitors Direct Connect connection status and triggers automated failover?

AWS CloudWatch with custom metrics only

AWS Route 53 health checks with failover routing

AWS Lambda automatic connection healing

AWS Config compliance monitoring

17. What is the maximum number of virtual interfaces per Direct Connect connection?

1 private VIF per connection

Up to 50 virtual interfaces

Unlimited virtual interfaces

Only 4 virtual interfaces maximum

18. Which BGP feature enables automatic failover between redundant Direct Connect connections?

BGP route summarization

BGP AS path prepending

BGP keepalive and hold timers

BGP community tags

19. In Direct Connect resiliency design, what is the recommended minimum number of connections for high availability?

One connection with backup

Two connections at the same location

Two connections at different locations

Four connections across all regions

20. Which redundancy model requires multiple Direct Connect connections at different AWS Direct Connect locations?

Single connection with automatic failover

Active-active redundancy across multiple locations

Passive standby at the same location

Mesh topology with no failover capability
