Q

Network tasks that are typically performed in the data plane are?

A

Network tasks that are typically performed in the data plane are:

encapsulation and decapsulation of packets, the adding or removing of trunk headers, the matching of MAC addys to a MAC address table, the matching of IP addresses to paths in a routing table, the encryption of data, NAT, and filtering by using either access control lists or port security.

Q

What are the four steps in the site-to-site VPN IPSec encryption process?

A
  1. The sending device encrypts the original packet and the session key.
  2. It then encapsulates the encrypted data with new headers.
  3. It then sends the encrypted packet to the destination device.
  4. Lastly the destination device decrypts the data and the session key.

Q

What is GRE?

A

Generic Routing Encapsulation is a tunneling protocol developed by Cisco Systems that can encapsulate a wide variety of network layer protocols inside virtual point-to-point links or point-to-multipoint links over an Internet Protocol network.

GRE provides broadcast and multicast packet encapsulation. it is a Cisco-proprietary protocol that can tunnel traffic from one network to another without requiring the transport network to support the network protocols in use at the tunnel source or destination. Security features are limited.

What does TACACS+ stand for?

A

Terminal Access Controller Access-Control System Plus.

17
Q

What are the differences between RADIUS and TACACS+?

A

RADIUS only encrypts the password where TACACS+ encrypts the entire content of the packet.

RADIUS combines the authentication and authorization services into a single function where TACACS+ separates these functions.

18
Q

What prefix is used for IPv6 unicast link-local addresses?

A

FE80::/10

Range FE80 through FEBF

19
Q

What prefix is used for IPv6 global unicast addresses?

A

2000::/3

20
Q

What prefix is used for unicast site-local addresses?

A

FC::/8 and FD00::/8

21
Q

What is a unicast address?

A

A unicast address is the most common form of an IP address and is assigned to one network interface.

22
Q

What prefix is used for multicast addresses?

A

FF00::/8

FF00 through FFFF

23
Q

What is an Anycast address

A

Like a multicast address, an anycast address identifies multiple interfaces; however, while multicast packets are accepted by multiple machines, anycast packets are delivered only to one interface (host). This address type allows for services that are provided by multiple servers where only one server has to respond. In routing, anycast addresses are used to route packets to the closest routers.

24
Q

What is a Global unicast address.

A

A global unicast address is simply what we call a public IP address in IPv4—that is, an IP address that is routed across the whole Internet. You can make out a global unicast address easily: The first three bits are set to 001. Thus, the address prefix of a global IPv6 address is 2000::/3 because 0010000000000000 is 2000 in hex.

25
Q

Which prefix will an IPv6-enabled computer use to automatically configure an IPv6 address for itself?

A

FE80::/10

26
Q

How many ports will be included in a LAG bundle by default?

A

Eight.

27
Q

Modes for Cisco’s PAgP protocol?

A

Auto and Desirable

28
Q

Modes for 802.3ad Link Aggregation Control Protocol- LACP?

A

Active and Passive

29
Q

What does the sh ip nat translations command show?

A

The sh ip nat translations command displays the mapping between internal and external Internet Protocol - IP - addresses when NAT is configured on a router

30
Q

What is the function of NAT?

A

NAT translates between public and private IP addresses to enable hosts on a privately addressed network to access a public network, such as the internet. NAT by default provides only a one-to-one mapping of addresses.

If multiple hosts require simultaneous access to the public network, NAT must be configured to use either a pool of public IP addresses or a NAT overloading.

31
Q

How often will Cisco switches send LLDP advertisements?

A

Cisco switches send LLDP advertisements every 30 seconds. Hold time is 4 times the advertisement time

32
Q

How often will Cisco switches send CDP advertisements?

A

Cisco switches send CDP advertisements every 60 seconds. Cisco proprietary protocol.

33
Q

Difference between CDP and LLDP?

A

CDP can provide VTP information, where LLDP cannot.

34
Q

How large is a jumbo frame?

A

A jumbo frame is up to 9,216 bytes.

35
Q

How large is a giant frame?

A

A giant frame is 1,518 bytes.

36
Q

How loarge is a baby giant frame?

A

A baby giant frame is up to 1,600 bytes
