15 Top Paying IT Certifications In 2017

World Wide Training Company ႀကီးတစ္ခုျဖစ္တဲ႔ Global Knowledge ကေန USA မွာ Survey ေကာက္ယူထားတဲ႔ ၂၀၁၇ အတြက္ လစာေကာင္းတဲ႔
အိုင္တီ လက္မွက္မ်ား ျဖစ္ပါတယ္။

ရည္ရြယ္ခ်က္ကေတာ႔ လမ္းေၾကာင္းေရြးခ်ယ္တဲ႔ေနရာမွာ လြယ္ကူေစရန္ျဖစ္ပါတယ္။
တကယ္လည္းလြယ္ကူေစပါတယ္။

Blog ရဲ႕မူရင္း္စာသားေလးမ်းျဖစ္ပါတယ္။

” The survey was distributed globally, but this article focuses on the United States data and variations exist based on where you work, your years of experience and the type of company you work for, but this is still helpful in deciding where to spend your time and money in earning additional certifications. ”

ခါတိုင္းႏွစ္မ်ားလို Security ကေတာ႔ Top ျဖစ္ေနဆဲ။ ထူးျခားတာကေတာ႔ Amazon AWS Cloud ကေနရာရယူလာတာပဲျဖစ္ပါတယ္။

တကယ္ေတာ႔ CCNA, JNCIA , MCSA, RHCSA, VCP အားလံုးဟာ သူ႕တန္ဖိုးနဲ႕သူျဖစ္ပါတယ္။ တကယ္ကၽြမ္းက်င္ရင္ Salary တစ္မ်ိဳး။ နည္းနည္းကၽြမ္းက်င္ရင္ Salary ကတစ္မ်ီဳး ျဖစ္ပါတယ္။ Language တကယ္ကၽြမ္းက်င္ရင္ Salary တစ္မ်ိဳး။ Language နည္းနည္းကၽြမ္းက်င္ရင္ Salary ကတစ္မ်ီဳး ျဖစ္ပါတယ္။

Specialize တစ္ခုခုကုိသိရင္ Salary ကတစ္မ်ိဳး။ Overall သိရင္ Salary ကတစ္မ်ိဳးျဖစ္ပါတယ္။ ဒါေလး အေရးႀကီးတယ္။ သိေစခ်င္ပါတယ္။

တစ္ခ်ိဳ႕ Associate Level Cert ေတြဟာ Professional ေတြထက္လစာပိုမ်ားေနတာ Professional Level Cert ေတြဟာ Expert ေတြထက္လစာပိုမ်ားေနတာ ဒါေၾကာင့္ျဖစ္ပါတယ္။

ခုေလာက္ဆို ေတြးစရာေလး တစ္ခုခု ရသြားလိမ့္မယ္လို႔ ထင္ပါတယ္။

ေက်းဇူးပါ

Networking Classes

I am now guiding and teaching some networking courses to help next generation engineers especially for Myanmar.  Now Teaching Courses are

• Network Foundation
CCNA
• CCNA-Security
• CCNP
• Microsoft MCTS 70-410

I love Networking.
I Love teaching. 🙂

Is Layer 2 Network important ?

Is Layer 2 Network important ?

If we can’t build the best Layer 2 network,
Our Network is
complex
not scalable
not secure
may be slow bandwidth
difficult management
difficult troubleshooting

If Layer 2 network doesn’t secure, we welcome the attackers and company assets can be lost. Vlan Hopping is one of the attacks.

” Disrupt the Bottom of the Wall, and the Top Is Disrupted, Too “

Everything at Layer 3 and higher is encapsulated into some type of Layer 2 frame. If the
attacker can interrupt, copy, redirect, or confuse the Layer 2 forwarding of data, that
same attacker can also disrupt any type of upper-layer protocols that are being used.

If we can’t monitor Layer 2 network easily, we can lack what happen our networks such as Performance,
Potential Risk etc.

It’ll be sure that building the best Layer 2 Network is the best Networks. 🙂

Enjoy

Cisco Hierarchical Network Design

Cisco has refined a hierarchical approach to network design that enables network designers to organize the network into distinct layers of devices. The resulting network is
Efficient
Intelligent
Scalable
Easily managed.

Three Layer of Network Design is Access Layer, Distribution Layer, Core Layer.

Access Layer
The access layer exists where the end users are connected to the network. Access switches usually provide Layer 2 (VLAN) connectivity between users. Devices in this layer sometimes called building access switches, should have the following capabilities:
■ Low cost per switch port
■ High port density
■ Scalable uplinks to higher layers
■ High availability
■ Ability to converge network services (that is, data, voice, video)
■ Security features and quality of service (QoS)

Distribution Layer
The distribution layer provides interconnection between the campus network’s access and core layers. Devices in this layer, sometimes called building distribution switches should have the following capabilities:
■ Aggregation of multiple access layer switches
■ High Layer 3 routing throughput for packet handling
■ Security and policy-based connectivity functions
■ QoS features
■ Scalable and redundant high-speed links to the core and access layers
The distribution layer usually is a Layer 3 boundary, where routing meets the
VLANs of the access layer.

Core Layer
A campus network’s core layer provides connectivity between all distribution layer devices. The core, sometimes referred to as the backbone, must be capable of switching traffic as efficiently as possible. Core switches should have the following attributes:
■ Very high Layer 3 routing throughput
■ No costly or unnecessary packet manipulations (access lists, packet filtering)
■ Redundancy and resilience for high availability
■ Advanced QoS functions

** But small or medium-size campus networks might not have the size or volume requirements that would require the functions of all three layers.

BGP Overview

It’s Exterior Gateway Protocol (EGP) that runs between AS (autonomous systems) to enable routing policies and improve security.

It’s used on the Internet.

Any communication between IGPs and the internet or between service providers will be accomplished through BGP.

Called Inter-domain Routing (Routing between Autonomous System).

Very Robust and scalable routing protocol.

Current over 500,000 routes on the internet.
