More questions
Correct Answer: 1, 3 and 6
Explanation:
DHCP, SNMP, and TFTP use UDP.
Correct Answer: access-list 100 permit tcp any 196.15.7.0 0.0.0.255 eq www
Explanation:
The first thing to check in a question like this is the access-list number. Right away, you can see that the second option is wrong because it is using a standard IP access-list number. The second thing to check is the protocol. If you are filtering by upper-layer protocol, then you must be using either UDP or TCP; this eliminates the fourth option. The third and last answers have the wrong syntax.
Correct Answer: It has the same timers as RIPv1.
Explanation:
RIPv2 is pretty much just like RIPv1. It has the same administrative distance and timers and is configured just like RIPv1.
Correct Answer: Check your interfaces for the correct configuration.
Explanation:
In order for NAT to provide translation services, you must have
ip nat inside and
ip nat outside configured on your router's interfaces.
Correct Answer: show ip interface
Explanation:
Only the
show ip interface command will tell you which interfaces have access lists applied.
show access-lists will not show you which interfaces have an access list applied.
Correct Answer: A network that has only one entry and exit point.
Explanation:
Stub networks have only one connection to an internetwork. Only default routes can be set on a stub network or network loops may occur.
Correct Answer: erase startup
Explanation:
The command
erase startup-config deletes the configuration stored in NVRAM.
Correct Answer: ping ::1
Explanation:
The loopback address with IPv4 is
127.0.0.1. With IPv6, that address is
::1.
Correct Answer: 3, 2, 1, none
Explanation:
Routers operate at layer 3. LAN switches operate at layer 2. Ethernet hubs operate at layer 1. Word processing applications communicate to the Application layer interface, but do not operate at layer 7, so the answer would be none.
Correct Answer: 1
Explanation:
You should have only one root bridge per network.
