Cards

Term
____________ can be used to filter the unwanted networks or packets out of the network.
Definition
Access-lists
Term
These access lists filter the traffic based on the source IP address of the router.
Definition
Standard Access lists
Term
_______________ allows us to make decisions based on source and destination addresses as well as port numbers thereby providing more granularity.
Definition
Extended Access lists
Term
What numbers are reserved for Standard Access lists?
Definition
1-99 and 1300-1999
Term
What numbers are reserved for extended access lists?
Definition
`100-199 and 2000-2699
Term
___________ access lists allows us to create both standard and extended named access lists.
Definition
Named
Term
_______________ ACLs are also called Dynamic access lists.
Definition
Lock and Key
Term
__________ ACLs automatically disconnect the user from the network after a brief idle connection.
Definition
Dynamic
Term
_____________ is used to permit or deny packets based on IP addresses with source/destination and TCP/UDP ports.
Definition
Reflexive ACL's
Term
___________ are based on time of day and week using the time and range command. It allows the addition of time constraint with an access list.
Definition
Time based ACL's
Term
At the end of access list there has to be a deny all or permit all. Why?
Definition
To tell the router what to do if there is no match
Term
This command displays all access list configured on the router
Definition
show access-list
Term
NAT is configured on the __________ in the network.
Definition
edge device
Term
It allows one to one mapping between private and global IP addresses. This implementation consumes one public IP address against one private address.
Definition
Static NAT
Term
This implementation of NAT allows a set of private IP addresses to be mapped to a single or more public IP addresses. This type of NAT does not use static configuration.
Definition
Dynamic NAT
Term
This type of NAT implementation is also known as PAT Port Address Translation.
Definition
Overloading NAT
Term
This type of translation further decreases the depletion of IP address space as only a single public IP address is used to translate multiple private addresses.
Definition
PAT
Term
This address refers to the inside source address before the NAT translation takes place.
Definition
Inside Local
Term
This is the destination host before the NAT translation takes place.
Definition
Outside Local
Term
This is the inside host after translation.
Definition
Inside Global
Term
This is the outside destination host after the translation takes place.
Definition
Outside Global
