Exhibit: A collector is receiving traffic metadata from a router, including source IP, destination IP, protocol, and byte counts. Which feature is being used?

A user types www.example.com into a browser. Which service is used first to resolve that name into an IP address?

Match each network service to its primary purpose.

Exhibit: A client receives an IP address but cannot reach remote networks. Which DHCP option is most likely missing or incorrect?

Match each network service to its primary function.

Exhibit: Inside hosts can reach the internet only one at a time. What is the most likely NAT issue?

Exhibit: PCs in VLAN 20 are not receiving addresses from a DHCP server in another subnet. The switch SVI for VLAN 20 is up, and routing is working. Which configuration is most likely missing on the gateway for VLAN 20?

On a router performing NAT, where should ip nat inside be applied?

Exhibit: A switch shows a clock that is several minutes off from other devices even though an NTP server has been configured. Which issue is the most likely cause?

Exhibit: An engineer wants a device to send only warning messages and more critical events to a syslog server. Which logging level should be configured?

Exhibit: A user can ping 8.8.8.8 successfully but cannot browse to www.example.com by name. Which service is the most likely failing component?

Exhibit: An engineer wants all devices to send logs to 10.10.10.50 and also stamp those logs with consistent time from 10.10.10.60. Which two configurations are required on a Cisco device?

Match each service with the best operational purpose.

Exhibit: A DHCP client on VLAN 30 is not receiving an address from a server located on another subnet. The SVI configuration is shown below. What should be added?

A branch router should automatically learn the IP address of a time source so logs from all devices show matching timestamps. Which service provides that function?

Exhibit: A network engineer wants to identify which applications are consuming most WAN bandwidth over time. Which feature should be enabled on the router?

Exhibit: A router is configured for NAT overload, but translations never appear when inside users browse the internet. Which issue is most likely?

Exhibit: A router is configured with an access list intended to block Telnet from 192.168.10.0/24 to 10.1.1.10, but Telnet still works. What is the most likely reason?

Exhibit: Users receive addresses from the correct subnet, but they cannot browse by hostname. Which DHCP option is most likely missing or incorrect?

A small office wants branch routers to automatically hand out IP addresses, default gateway values, and DNS servers to clients. Which service should be configured?

Match each service to its primary function.

Exhibit: A branch router receives time from an NTP server, but the show output marks the server with a tilde instead of an asterisk. What does that mean?

Exhibit: A named standard ACL is configured to permit only the 192.168.30.0/24 subnet, but users from 192.168.31.0/24 are still passing traffic. What is the most likely reason?

Exhibit: A router is configured for PAT overload. What does the inside global address represent for an internal PC?

Exhibit: Users complain that log timestamps from several routers do not line up with one another. Which two actions are most appropriate?

Exhibit: A company wants to export traffic statistics from routers to a collector for visibility into top talkers and application usage. Which two statements are accurate?

Which protocol is used to resolve a hostname such as www.example.com into an IP address?

A branch router is acting as a DHCP server. Which two parameters can it provide directly to clients through DHCP?

A router is configured as a DHCP server for VLAN 20. Clients on the VLAN can reach the default gateway, but they do not receive leases. Which two configuration issues on the router would directly prevent successful address assignment?

A company wants all routers and switches to use a common time source so log timestamps line up during incident review. Which two statements about NTP are correct?

Users can browse websites by IP address but not by hostname. The default gateway is reachable and general internet connectivity works. Which two causes are the most likely?

A network team wants to collect flow-level traffic statistics from routers to identify top talkers and bandwidth consumers. Which two statements about NetFlow are correct?

A branch office uses PAT overload on the edge router. Inside users can reach the internet, but return traffic for a newly deployed server must be mapped to a specific inside host. Which two statements are correct?

A network operations team wants centralized logging from routers and switches and also wants meaningful severity filtering. Which two statements about syslog are correct?

You have a storage account named stproddata01 that contains application data in a blob container. Users sometimes delete blobs accidentally and need a way to recover those deleted blobs for several days. You want the simplest solution with minimal operational effort. What should you configure?
