When is a Connected Route Not Used?

I ran into this situation on a recent project and thought it would make an excellent question on an exam. It could be worded something like this:

What is the behavior of a router or Layer 3 switch when a dynamic route is learned that partially overlaps with a directly connected network?

  1. The router reboots
  2. The network reboots
  3. That's um-possible
  4. None of the above

What is hyperconvergence?

Hyperconvergence is an IT framework that combines storage, computing and networking into a single system in an effort to reduce data center complexity and increase scalability. Hyperconverged platforms include a hypervisor for virtualized computing, software-defined storage, and virtualized networking, and they typically run on standard, off-the-shelf servers. Multiple nodes can be clustered together to create pools of shared compute and storage resources, designed for convenient consumption. The use of commodity hardware, supported by a single vendor, yields an infrastructure that's designed to be more flexible and simpler to manage than traditional enterprise storage infrastructure. For IT leaders who are embarking on data center modernization projects, hyperconvergence can provide the agility of public cloud infrastructure without relinquishing control of hardware on their own premises.To read this article in full or to leave a comment, please click here

Intel tightens data-center grip with Xeon Scalable Processor platform

Make no mistake: Intel's Xeon Processor Scalable Family, based on the company's Skylake architecture, is about much more than revving up CPU performance. The new processor line is essentially a platform for computing, memory and storage designed to let data centers -- groaning under the weight of cloud traffic, ever-expanding databases and machine-learning data sets -- optimize workloads and curb operational costs.In order to expand the market for its silicon and maintain its de facto processor monopoly in the data center, Intel is even starting to encroach on server-maker turf by offering what it calls Select Solutions, generally referred to in the industry as engineered systems -- packages of hardware and software tuned to specific applications.To read this article in full or to leave a comment, please click here

Worth Reading: Take a pause on ransomware

As these devastating global ransomware attacks illustrate, cybersecurity is not an issue that can be ignored. Any time a device or system is connected to the Internet, it is a potential target. What was once just another lucrative means of extorting money from Internet users, ransomware is emerging as a preferred tool for causing widespread disruption of vital services such as hospitals, banks, shipping, or airports. Attacks are growing more sophisticated and more enduring, with longer term damaging effects and wider impact. Ransomware exploits the slow pace of security patching, systems that are dependent on old software, and poor backup practices. It also provides a smokescreen for other nefarious acts including stealing data and credentials, or even wiping data. So, the name “ransomware” becomes illusory: what we are really dealing with is “hydraware.” —The Internet Society

Rough Guide to IETF 99: DNS Privacy and Security, including DNSSEC

There's a good bit of DNS secrurity and privacy activity happening at IETF 99 next week in Prague, although not all of that is in working groups. Here is a view of what is going on.

IETF 99 Hackathon

Once again there will be a good-sized "DNS team" at the IETF 99 Hackathon over the weekend (15-16 July). The IETF 99 Hackathon wiki outlines the work (scroll down to see it). From a security point of view, major projects include:
