IP Connectivity Q/A's Flashcards
What does the network prefix identify?
network class
The Network ID/Subnet Mask is used to divide… in what two things?
IP address into networks and host address
Next hop address is the next address that…?
Next address that a router is going to forward data packets to
Administrative distance in routing is use to determine what two things of a route?
distance and trustworthiness
Metrics are calculated with the administrative distance in order to determine what?
best routing decisions
The gateway of last resort is a default route where?
all packets are forwarded to reach other routers.
Routing protocols use what three things to choose the best routing decisions?
Administrative distance
Metric
Prefix length
What is a floating static route?
backup static route that is used in the event of a failure
What is a default route?
Where all packets forward to by default
First hop redundancy protocol (FHRP) eliminates…?
single points of failure
What two things are used in order for form the first hop redundancy protocol (FHRP) backup active and standby routers over the network?
Virtual IP and MAC Address
What type of messages are sent from the Hot Standby Router (HSRP) to other HSRP routers?
Hello Messages
When the state of a standby router stops receiving hello messages, what happens?
router transitions from standby to the active router
When HSRP routers are elected as the active and standby router in what priority order is the election made?
What is the default priority value of HSRP routers?
If the priority of HSRP routers tie, is the highest or lowest IP address used for it’s election?
highest and then lowest priority
100
highest IP address
What must be enabled on a router in order for it to fail-over when using a router redundancy protocol?
pre-emption
