Which command enables a router to become a DHCP client?
The correct answer is A. Option A: ip address dhcp
Explanation
OSPF elects a designated router on multiaccess networks to reduce adjacency and LSA exchange overhead. DHCP dynamically supplies clients with IP configuration parameters.
Which function does an SNMP agent perform?
The correct answer is A. Option A: It sends information about MIB variables in response to requests from the NMS
What are two roles of the Dynamic Host Configuration Protocol (DHCP)? (Choose two.)
The correct answer is B, D. Option B: The DHCP server leases client IP addresses dynamically. Option D: The DHCP server offers the ability to exclude specific IP addresses from a pool of IP addresses.
Explanation
OSPF elects a designated router on multiaccess networks to reduce adjacency and LSA exchange overhead. DHCP dynamically supplies clients with IP configuration parameters.
Which command must be entered when a device is configured as an NTP server?
The correct answer is B. Option B: ntp master
Explanation
NTP synchronizes device clocks so logs, certificates, and operations share consistent time.
What event has occurred if a router sends a notice level message to a syslog server?
The correct answer is B. Option B: An interface line has changed status
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.)
The correct answer is B, C. Option B: R2(config)# interface gi0/0 R2(config-if)# ip helper-address 198.51.100.100 Option C: R1(config)# interface fa0/0 R1(config-if)# ip address dhcp R1(config-if)# no shutdown
Explanation
OSPF elects a designated router on multiaccess networks to reduce adjacency and LSA exchange overhead. DHCP dynamically supplies clients with IP configuration parameters.
Which two actions are performed by the Weighted Random Early Detection mechanism? (Choose two.)
The correct answer is D, E. Option D: It can mitigate congestion by preventing the queue from filling up. Option E: It drops lower-priority packets before it drops higher-priority packets.
Explanation
OSPF elects a designated router on multiaccess networks to reduce adjacency and LSA exchange overhead.
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?
The correct answer is D. Option D: 172.23.104.4
If a notice-level message is sent to a syslog server, which event has occurred?
The correct answer is C. Option C: A routing instance has flapped.
Which two tasks must be performed to configure NTP to a trusted server in client mode on a single network device? (Choose two.)
The correct answer is B, C. Option B: Verify the time zone. Option C: Specify the IP address of the NTP server.
Explanation
OSPF elects a designated router on multiaccess networks to reduce adjacency and LSA exchange overhead. NTP synchronizes device clocks so logs, certificates, and operations share consistent time.
What is the primary purpose of a First Hop Redundancy Protocol?
The correct answer is D. Option D: It reduces routing failures by allowing more than one router to represent itself as the default gateway of a network
Explanation
A host sends traffic for remote IP networks to its configured default gateway.
An engineer is configuring NAT to translate the source subnet of 10.10.0.0/24 to any one of three addresses: 192.168.3.1, 192.168.3.2, or 192.168.3.3. Which configuration should be used?
The correct answer is D. Option D: enable configure terminal ip nat pool mypool 192.168.3.1 192.168.3.3 prefix-length 30 access-list 1 permit 10.10.0.0 0.0.0.255 ip nat inside source list 1 pool mypool interface g1/1 ip nat inside interface g1/2 ip nat...
Explanation
NAT translates addresses between network domains, commonly conserving public IPv4 addresses.
When the active router in an HSRP group fails, which router assumes the role and forwards packets?
The correct answer is C. Option C: standby
What protocol allows an engineer to back up 20 network router configurations globally while using the copy function?
The correct answer is C. Option C: FTP
Which type of address is the public IP address of a NAT device?
The correct answer is C. Option C: inside global
Which two pieces of information can you determine from the output of the show ntp status command? (Choose two.)
The correct answer is B, D. Option B: the IP address of the peer to which the clock is synchronized Option D: whether the clock is synchronized
Explanation
OSPF elects a designated router on multiaccess networks to reduce adjacency and LSA exchange overhead.
Which keyword in a NAT configuration enables the use of one outside IP address for multiple inside hosts?
The correct answer is D. Option D: overload
Which feature or protocol determines whether the QOS on the network is sufficient to support IP services?
The correct answer is C. Option C: IP SLA
In QoS, which prioritization method is appropriate for interactive voice and video?
The correct answer is C. Option C: low-latency queuing
What is the purpose of traffic shaping?
The correct answer is D. Option D: to limit the bandwidth that a flow can use
