You are configuring EIGRP MD5 authentication. After creating the key chain and key string, which command must be applied to the interface to enable MD5 spesifically?
ip ospf authentication message-digest
ip authentication mode eigrp <AS> md5

service password-encryption
In the EIGRP metric calculation formula, which two values are used by default ( K1 and K3 )?
Bandwidth and Load

A router has learned a route via EIGRP with an Administrative Distance (AD) of 90. What does this indicate?
It is an External EIGRP route
It is an Internal EIGRP route
The route was redistributed from OSPF
The route is a summary address
Which standard IEEE protocols is OSPF based on, and what algorithm does it use to calculate the shortest path?
Distance Vector; Bellman-Ford
Link State; DUAL
Link State; Djikstra ( SPF )
Hybrid; K-values
When configuring OSPF Plaintext authentication, which two steps are required on the interface?
Enable MD5 mode and configure a key-chain
Enable Null authentication and set a priority
Enable simple password authentication and configure the authentication key
Configure a username and secret password
You are troubleshooting an OSPF adjacency that is stuck in the EXTART or EXCHANGE state. What is the most likely cause?
Mismatched Hello Timers
Mismatched MTU size on the link
Mismatched Area IDs
Missing authentication passwords
In OSPF MD5 authentication, what specific must match on both neighbors regarding the key configuration?
The key ID and the Key String
The Key chain name only
The encryption level ( Type 5 vs Type 7 )
The password length only
In a broadcast multi-access network ( like Ethernet ), how does OSPF determine the Designated Router (DR) ?
The router with the lowest MAC address
The router with the highest OSPF Priority, followed by the highest Router ID
The router with the lowest OSPF Cost
The router that has been up the longest
Which of the following is an industry-standard protocol for link aggregation (EtherChannel)?
PAgP
LACP ( 802.3ad)
STP
DTP
You want to configure an EtherChannel using LACP where the switch actively attempts to negotiate the channel. Which mode should you use?
Desirable
Auto
Active
Passive
Which combination of PAgP modes will successfully form an EtherChannel?
Auto + Auto
Desirable + Auto
Passive + Passive
On + Desirable
To configure a Layer 3 EtherChannel , what command must be issued on the physical interfaces and the port-channel interface before assigning an IP address?
switchport mode trunk
no switchport
ip routing
channel-group 1 mode on
