✍️ Sample CCST Questions & Answers
1. Which protocol is used to automatically assign IP addresses, subnet masks, default gateways, and DNS server addresses to network hosts?
DHCP (Dynamic Host Configuration Protocol) automatically provides IP configuration parameters to network clients, eliminating the need for manual configuration.
2. What is the broadcast address for the subnet 10.0.0.64/26?
The /26 block starting at .64 spans .64–.127, so .127 is the broadcast address.
3. Which command on a Cisco router shows the current routing table including all known routes?
The 'show ip route' command displays the router's routing table, listing all known networks with their associated routing protocol, administrative distance, metric, and next-hop information.
4. A user reports intermittent connectivity drops every few minutes. Which tool would BEST help identify whether the issue is packet loss or latency spikes?
Running ping with a high count (e.g., ping -n 100) over time reveals packet loss percentages and latency variations.
5. Which Cisco IOS command displays the MAC address table on a Catalyst switch?
The 'show mac address-table' command on a Cisco Catalyst switch displays all learned MAC addresses and their associated port and VLAN information.
6. A network administrator wants to control which devices can connect to a specific switch port based on MAC addresses. Which feature should be configured?
Port security allows a switch port to be locked to specific MAC addresses, restricting which devices can connect to that port.
