HSRP
Hot Standby Router Protocol
HSRP default Hello Packet interval
3 seconds
Gateway Router is elected based on?
priority value
Gateway router also known as
Active router
Multiple routers with same priority determination?
router with the highest IP address is elected active router
Router with the second highest priority value or IP address if priority is equal is the
Standby Router
Which router monitors Hello Packets?
Standby router monitors active routers Hello Packets
Standby default hold time to receive Hello Packets
10 seconds
If a Hello packet is not received from the Active router in 10 seconds what occurs?
The Standby router assumes the active router has failed and becomes the active router.

Switch Port modes
Auto
Desirable
Auto Switch port mode
operates in access mode unless the neighboring interface actively negotiates to operate as a trunk.
Desirable switch port mode
operates in access mode unless it can actively negotiate a trunk connection with a neighboring device.

EIGRP
By default what metrics does EIGRP use to determine the best path?
Bandwidth and Delay
What are two optional metrics EIGRP can use to determine best path?
load and reliability
What is Bandwidth?
The throughput of a link
What is delay?
The length of time required to send a packet to a destination.
What is load?
the amount of data activity over a link
What is reliability?
the bit-error rate of the link
What metric does OSPF use to determine best path?
Bandwidth
What metric does RIP/RIPv2 use to determine best path?
Hop Count
Maximum RIP hop count?

PPP
Point to Point Protocol
Two PPP authentication methods
PAP and CHAP
HDLC
High-Level Data Link Control
Switchport Security Mode Protect
Discards unauthorized traffic
Switchport Security Mode Shutdown
Discards the unauthorized traffic, logs the entry attempt, increments the security violation counter, disables the port.
Switchport Security mode Restrict
Discards the traffic, logs the entry attempt, increments the security violation counter, sends an SNMP trap message/

What is an FHRP?
Protocols that are used to provide Layer 3 gateway redundancy
What to devices in a Layer 3 redundancy typically share?
a virtual IP address that is configured as the gateway on each host
What type of routing is easy to configure and minimizes
static
AS into areas
OSPF
Which HSRP router or routers will use the HSRP virtual IP address and will respond to ARP requests with the HSRP virtual MAC address?
only the active router
What action does port security perform?
It authorizes traffic sent from a specified MAC to enter a port.
Which features are provided by IPSec
Data Origin Authentication
Data Confidentiality
Data Integrity
What characteristics does Cisco recommend for a strong password?
