Networking Protocols, VPN, and Routing Worksheet

Front

Which protocol uses SSH to securely transfer files?

Back

SFTP

Answer explanation

SFTP (SSH File Transfer Protocol) uses SSH to securely transfer files, providing encryption and secure authentication. Unlike FTP and TFTP, which do not offer secure file transfer, SFTP ensures data integrity and confidentiality.

Front

What type of VPN sends all network traffic through the tunnel?

Back

Full Tunnel

Answer explanation

A Full Tunnel VPN routes all network traffic through the secure tunnel, ensuring that all data is encrypted and protected. In contrast, a Split Tunnel only routes specific traffic, leaving some data unprotected.

Front

A user connecting from home to their office network is using what type of VPN?

Back

Client-to-Site

Answer explanation

A user connecting from home to their office network is using a Client-to-Site VPN. This type allows individual users to connect securely to a remote network, unlike Site-to-Site which connects entire networks.

Front

Which dynamic routing protocol is limited to 15 hops?

Back

RIP

Answer explanation

RIP (Routing Information Protocol) is limited to a maximum of 15 hops, making it suitable for smaller networks. In contrast, OSPF, EIGRP, and BGP do not have this limitation, allowing for larger and more complex network topologies.

Front

Which routing protocol is Cisco proprietary and considered hybrid?

Back

EIGRP

Answer explanation

EIGRP (Enhanced Interior Gateway Routing Protocol) is a Cisco proprietary protocol that combines features of both distance-vector and link-state protocols, making it a hybrid routing protocol.

Front

What allows multiple VLANs to pass over a single port?

Back

Trunk Port

Answer explanation

A Trunk Port allows multiple VLANs to pass over a single port by tagging the frames with VLAN IDs. This enables the switch to differentiate between the traffic of different VLANs, unlike an Access Port, which carries traffic for only one VLAN.

Front

What DNS record maps a hostname to an IPv4 address?

Back

A

Answer explanation

The 'A' record is used to map a hostname to an IPv4 address, making it the correct choice. The 'AAAA' record maps to IPv6 addresses, 'PTR' is for reverse lookups, and 'MX' is for mail exchange servers.

Front

Which protocol assigns IP addresses automatically?

Back

DHCP

Answer explanation

DHCP (Dynamic Host Configuration Protocol) automatically assigns IP addresses to devices on a network, allowing them to communicate without manual configuration. Other options like DNS, SNMP, and NAT serve different purposes.

Front

Which tool would you use to test DNS resolution? Options: ipconfig, nslookup, traceroute, ping

Back

nslookup

Answer explanation

The correct tool for testing DNS resolution is 'nslookup'. It queries DNS servers to obtain domain name or IP address mapping, making it ideal for checking DNS functionality.

Front

Which command shows the routing table?

Back

route

Answer explanation

The 'route' command displays the routing table, which shows the paths that data packets take to reach their destinations. Other options like 'netstat' and 'hostname' do not specifically show the routing table.
