You have configured a router with an OSPF router ID, but its IP address still reflects the physical interface. Which action can you take to correct the problem in the least disruptive way?
AReload the OSPF process.
BSpecify a loopback address
CReboot the router.
DSave the router configuration
Correct Answer:A
Once an OSPF Router ID selection is done, it remains there even if you remove it or configure another OSPF Router ID. So the least disruptive way is to correct it using the command "clear ip ospf process".

Choose 2 — select all that apply
BNeighbors must be specifically declared in the configuration of each device

Which two pieces of information can you determine from the output of the show ntp status command? (Choose two)
Choose 2 — select all that apply
Awhether the NTP peer is statically configured
Bthe IP address of the peer to which the clock is synchronized
Cthe configured NTP servers
Dwhether the clock is synchronized
Ethe NTP version number of the peer
Correct Answer:BD
Below is the output of the "show ntp status" command. From this output we learn that R1 has a stratum of 10 and it is getting clock from 10.1.2.1.

Which keyword in a NAT configuration enables the use of one outside IP address for multiple inside hosts?
Asource
Bstatic
Cpool
Doverload
Correct Answer:D
By adding the keyword "overload" at the end of a NAT statement, NAT becomes PAT (Port Address Translation). This is also a kind of dynamic NAT that maps multiple private IP addresses to a single public IP address (many-to-one) by using different ports. Static NAT and Dynamic NAT both require a one-to-one mapping from the inside local to the inside global address. By using PAT, you can have thousands of users connect to the Internet using only one real global IP address. PAT is the technology that helps us not run out of public IP address on the Internet. This is the most popular type of NAT.
