Routing & Advanced Switching

A network technician is using traceroute on a corporate network to make use of ICMP "Time Exceeded" in order to identify routers along a delivery path.

What is the TCP/IP feature that traceroute uses to accomplish this.?

• Time to Live (TTL) header field

• Default route

• Fragmentation

• Static route

What is the default probe message type used by the tracert command on Windows systems?

• ARP request

• TCP SYN

• UDP

• ICMP Echo request

Which command outputs the active routing table and includes details such as destination, gateway, and the source of the route?

• show arp

• ip route show

• route print

• show route

What is the purpose of inspecting the ARP cache table?

• To modify the device's IP address

• To discover duplicate IP addresses and misconfigurations

• To view the device's routing table

• To increase the router's memory

What is the purpose of the hello messaging in EIGRP?

• To assign IP addresses to routers

• To encrypt data packets

• To transmit routing updates

• To confirm connectivity with its neighbors

What type of routing system is OSPF considered to be?

• Hierarchical

• Linear

• Circular

• Flat

Under which of the following circumstances might you implement BGP on your company network and share routes with internet routers?

• If the network is connected to the Internet using multiple ISPs

• If the network has over 15 hops

• If the network is connected to the Internet using public addressing

• If the network has over 15 areas and uses IPV6

What protocol does BGP use for its operation?

• ARP

• TCP

• UDP

• ICMP

Your company has recently expanded its operations and opened a new branch office. As the IT manager, you are tasked with setting up the network infrastructure for this new location. The office will connect to the company's main data center via the Internet for access to centralized resources.

You need to select a router that will manage the traffic between the branch office's local area network (LAN) and the wide area network (WAN) internet access efficiently.

Which type of router would be most suitable for this purpose?

• Core router

• Virtual router

• Edge router

• Wireless router

What is the primary role of an edge router in a network?

• 
  

  To provide Wi-Fi connectivity to internal users

• To serve as the main firewall for the network

• To manage internal network traffic only

• To connect internal networks to external networks
