Design & FHRP

Front

What is a characteristic of the spine-and-leaf architecture?

Back

Each device is separated by the same no. of hops

Front

What is the path for traffic sent from one user workstation to another workstation on a separate switch in a 3 tier architecture model?

Back

access - distribution - core - distribution - access

Answer explanation

A better way of you thinking about this is if you thought that it is a workstation in another building or site in the same company.

Front

Which function is performed by the collapsed core layer in a 2 tier architecture?

Back

Enforcing routing policies

Front

Which way does a spine-and-leaf architecture allow for scalability in a network when additional access ports are required?

Back

A leaf switch can be added with connections to every spine switch.

Front

How are the switches in a spine-and-leaf topology interconnected?

Back

Each leaf switch is connected to each spine switch.

Answer explanation

There are debates over this one. Some say that each leaf connects to two spine switches, making a loop. My thoughts are that the leaf has to connect to how many ever spine switches there are.

Front

What is the primary purpose of a First Hop Redundancy Protocol (FHRP)?

Back

It reduces routing failures by allowing more than one router to represent itself as the def. gateway of a network.

Front

How does HSRP provide 1st hop redundancy?

Back

It uses a shared virtual MAC and IP add to a group of routers that serve as the def. gw for LAN hosts

Front

Which virtual MAC address is used by VRRP group 1?

Back

0000.5e00.0101

Answer explanation

0000.5E00.01xx is VRRP virtual MAC. 0000.0c07.acxx is HSRP virtual MAC address. 0007.b400.xxyy is GLBP virtual MAC where xx is group and yy is AVF

Front

What is the benefit of using FHRP?

Back

Higher degree of availability

Front

When the active router in an HSRP group fails, what router assumes the role and forwards packets?

Back

Standby
