A single function applied to the data in a job flow. The sum of all steps comprises a job flow. The type of work done in a step. A feature of the Elastic Load Balancing load balancer that binds a user's session to a specific application instance so that all requests coming from the user during the session are sent to the same application instance. By contrast, a load balancer defaults to route each request independently to the application instance with the smallest load.

A word that is not indexed and is automatically filtered out of search requests because it is either insignificant or so common that including it would result in too many matches to be useful. Stop words are language-specific. A utility that comes with Hadoop that enables you to develop MapReduce executables in languages other than Java.

The ability to use a media file in real time—as it is transmitted in a steady stream from a server. Before you calculate an HMAC signature, you first assemble the required components in a canonical order. The preencrypted string is the string-to-sign. An attribute that specifies the strings that AWS WAF searches for in a web request, such as a value in a header or a query string.

A read process that returns a response with the most up-to-date data, reflecting the updates from all prior write operations that were successful—regardless of the region. Search criteria specified using the Amazon CloudSearch structured query language. You use the structured query language to construct compound queries that use advanced search options and combine multiple search criteria using Boolean operators.

You can create subnets to group instances according to security and operational needs. Specifies an index field you want to use to get autocomplete suggestions and options that can enable fuzzy matches and control how suggestions are sorted.

Documents that contain a match for the partial search string in the field designated by the suggester. Amazon CloudSearch suggestions include the document IDs and field values for each matching document. To be a match, the string must match the contents of the field starting from the beginning of the field. A type of bounce that occurs while the email servers of the sender and receiver are actively communicating. A word that is the same or nearly the same as an indexed word and that should produce the same results when specified in a search request.

For example, a search for "Rocky Four" or "Rocky 4" should return the fourth Rocky movie. This can be done by designating that four and 4 are synonyms for IV. Applying a tag to an AWS resource. A way to format return path email addresses so that you can specify a different return path for each recipient of a message. Tagging enables you to support VERP. Amazon ML uses the target attribute to learn how to make predictions on new data. The most recent version of the application revision that has been uploaded to the repository and will be deployed to the instances in a deployment group.

In other words, the application revision currently targeted for deployment. This is also the revision that will be pulled for automatic deployments. An instantiation of a task definition that is running on a container instance. The blueprint for your task. Specifies the name of the task , revisions, container definition s, and volume information.

An EC2 instance that runs Hadoop map and reduce tasks, but does not store data. Task nodes are managed by the master node , which assigns Hadoop tasks to nodes and monitors their status. While a job flow is running you can increase and decrease the number of task nodes. Because they don't store data and can be added and removed from a job flow, you can use task nodes to manage the EC2 instance capacity your job flow uses, increasing capacity to handle peak loads and decreasing it later.

Includes an access key ID , a secret access key , a session token, and an expiration time. The automatic restricting or slowing down of a process based on one or more limits. Amazon Kinesis Data Streams throttles operations if an application or group of applications operating on the same stream attempts to get data from a shard at a rate faster than the shard limit.

Amazon API Gateway uses throttling to limit the steady-state request rates for a single account. Amazon SES uses throttling to reject attempts to send email that exceeds the sending limits. Data provided as part of a metric. The time value is assumed to be when the value occurred. A metric is the fundamental concept for Amazon CloudWatch and represents a time-ordered set of data points. You publish metric data points into CloudWatch and later retrieve statistics about those data points as a time-series ordered data set.

The process of splitting a stream of text into separate tokens on detectable boundaries such as whitespace and hyphens. A communication channel to send messages and subscribe to notifications. It provides an access point for publishers and subscribers to communicate with each other. A datasource that contains the data that Amazon Machine Learning uses to train the machine learning model to make predictions. The act of a revision in a pipeline continuing from one stage to the next in a workflow.

A cryptographic protocol that provides security for communication over the internet. The trust policy specifies which principal s are allowed to use the role. Selecting the number and type of AMIs to run a Hadoop job flow most efficiently. A route for transmission of private network traffic that uses the internet to connect nodes in the private network.

The tunnel uses encryption and secure protocols such as PPTP to prevent the traffic from being intercepted as it passes through public routing nodes. The number of potential occurrences is not limited by a set number.

Standard measurement for the values submitted to Amazon CloudWatch as metric data. You can generate and download usage reports from https: Each user has a unique name within the AWS account, and a set of security credentials not shared with other users. These credentials are separate from the AWS account's security credentials.

Each user is associated with one and only one AWS account. Instances of attributes for an item, such as cells in a spreadsheet. An attribute might have multiple values. A specific tag label that acts as a descriptor within a tag category key. The process of confirming that you own an email address or a domain so that you can send email from or to it. Variable Envelope Return Path.

A way in which email sending applications can match bounce d email with the undeliverable address that caused the bounce by using a different return path for each recipient.

Product Reviews Average Rating: I jumped right to the redistribution lab and it has IS IS.

IS IS was retired many yeas ago. Now CCNP route is and this is due for refresh. I ran the update utility and it says all my files are current and I am worried about paying good money to get 10 year old content. Sending e-mail to tech support to see how this gets resolved. Currently I am gonna say 1 star and we will how this plays out. I received response that many universities still use boson to teach ISIS fpr the route exam.

Next I come back an check and my review has been modified to 5 starts and not posted. This seems like it is not consistent with best business practices. Good to get the basics but not good to practice real world simulations when configuring a lab. For the price charged for the simulators and practice exams they should be more up to date with what is being used in everyday businesses.
