Free AZ-700 Routing Questions and Answers — Questions and Answers
Question 1: Which routing protocol is commonly used in large enterprise networks and supports both IPv4 and IPv6?
- RIP
- OSPF (Correct answer)
- EIGRP
- BGP
Correct answer: OSPF
OSPF (Open Shortest Path First) is a widely used link-state routing protocol known for its scalability and efficiency in large enterprise networks. It supports both IPv4 and IPv6, making it a versatile choice for modern network infrastructures that require robust and fast convergence for routing decisions.
Question 2: What is the primary purpose of using a default route in a routing table?
- To handle all local traffic
- To forward packets to a specific subnet
- To route traffic to destinations not explicitly listed in the routing table (Correct answer)
- To prioritize certain types of traffic
Correct answer: To route traffic to destinations not explicitly listed in the routing table
A default route acts as a "gateway of last resort" in a routing table. Its primary purpose is to forward packets to any destination that does not have a more specific route explicitly defined. This ensures that traffic can reach external networks, such as the internet, even if the exact destination is unknown to the local router.
Question 3: Which command can be used to view the routing table on a Windows server?
- ipconfig
- route print (Correct answer)
- netstat -r
- tracert
Correct answer: route print
The `route print` command is the standard utility on Windows operating systems for displaying the local IP routing table. It provides detailed information about network destinations, gateways, interfaces, and metrics. This command is crucial for network troubleshooting, verifying connectivity, and understanding how a Windows server routes traffic.
Question 4: In Azure Virtual Network (VNet) routing, what is the main use of a User Defined Route (UDR)?
- To automatically update routing tables
- To simplify network management
- To create a backup route
- To override Azure's default system routes (Correct answer)
Correct answer: To override Azure's default system routes
User Defined Routes (UDRs) in Azure allow administrators to create custom routing rules that override Azure's default system routes. This provides granular control over network traffic flow within and between VNets, enabling scenarios like forced tunneling to a firewall or routing traffic to a Network Virtual Appliance (NVA) for security or optimization.
Question 5: When configuring BGP (Border Gateway Protocol) on Azure, what is the purpose of specifying AS (Autonomous System) numbers?
- To identify individual routers within a network
- To assign unique IP addresses to devices
- To identify and differentiate routing domains (Correct answer)
- To control access to the network
Correct answer: To identify and differentiate routing domains
In BGP (Border Gateway Protocol), Autonomous System (AS) numbers are unique identifiers assigned to routing domains. They are crucial for BGP to establish peering relationships and exchange routing information between different administrative entities. This differentiation allows for scalable and controlled inter-domain routing on the internet and in cloud environments like Azure.
