Which two statements about NTP operations are true? (Choose two.) Cisco routers can act as both NTP authoritative servers and NTP clients. Cisco routers can act only as NTP servers. Cisco routers can act only as NTP clients. NTP uses TCP over IP.

Which command enables a router to become a DHCP client? ip address dhcp ip dhcp client ip helper-address ip dhcp pool.
Which function does an SNMP agent perform? It sends information about MIB variables in response to requests from the NMS It manages routing between Layer 3 devices in a network It coordinates user authentication between a network device and a TACACS+ or RADIUS server It requests information from remote network nodes about catastrophic system events.
What are two roles of the Dynamic Host Configuration Protocol (DHCP)? (Choose two.) The DHCP server assigns IP addresses without requiring the client to renew them. The DHCP server leases client IP addresses dynamically. The DHCP client is able to request up to four DNS server addresses. The DHCP server offers the ability to exclude specific IP addresses from a pool of IP addresses. The DHCP client maintains a pool of IP addresses it is able to assign.
Which command must be entered when a device is configured as an NTP server? ntp peer ntp master ntp authenticate ntp server.
What event has occurred if a router sends a notice level message to a syslog server? A certificate has expired An interface line has changed status A TCP connection has been torn down An ICMP connection has been built.
Refer to the exhibit. An engineer deploys a topology in which R1 obtains its IP configuration from DHCP. If the switch and DHCP server configurations are complete and correct, which two sets of commands must be configured on R1 and R2 to complete the task? (Choose two.) R1(config)# interface fa0/0 R1(config-if)# ip helper-address 198.51.100.100 R2(config)# interface gi0/0 R2(config-if)# ip helper-address 198.51.100.100 R1(config)# interface fa0/0 R1(config-if)# ip address dhcp R1(config-if)# no shutdown R2(config)# interface gi0/0 R2(config-if)# ip address dhcp R1(config)# interface fa0/0 R1(config-if)# ip helper-address 192.0.2.2.
Which two actions are performed by the Weighted Random Early Detection mechanism? (Choose two.) It supports protocol discovery. It guarantees the delivery of high-priority packets. It can identify different flows with a high level of granularity. It can mitigate congestion by preventing the queue from filling up. It drops lower-priority packets before it drops higher-priority packets.
Refer to the exhibit. An engineer configured NAT translations and has verified that the configuration is correct. Which IP address is the source IP after the NAT has taken place? 10.4.4.4 10.4.4.5 172.23.103.10 172.23.104.4.
If a notice-level message is sent to a syslog server, which event has occurred? A network device has restarted. A debug operation is running. A routing instance has flapped. An ARP inspection has failed.
