questions with verified answers
Actions on Objectives Ans✓✓✓-Once the cyber attackers establish access to the
organization, they then execute actions to achieve their objectives / goal.
Address Resolution Protocol (ARP) Ans✓✓✓-A communication protocol used for
discovering the link layer address, such as a MAC address, associated with a given
network layer address, typically an IPv4 address.
Ansible Ans✓✓✓-An open-source suite of tools for software provisioning,
configuration management, and application deployment
agentless and relies on temporary remote connections (over standard SSH by
default) without installing agents on the controlled node.
Works with "playbooks" which are configuration files written in YAML and are
used to store automation instructions.
Application layer Ans✓✓✓-Contains the typical network applications or functions
organizations use and talk to control layer via NBI
Application Level MTD Ans✓✓✓-Involves a change in the application required,
source code, memory mapping, and software version.
Apstra Ans✓✓✓-Juniper software that automates and validates your data center
network design, deployment, and operations across a wide range of vendors.
,asset Ans✓✓✓-Anything of value to an organization
Attack Ans✓✓✓-An action triggered by deploying an attacking method, when a
vulnerability is exploited to actually realize a threat.
Barbican Ans✓✓✓-OpenStack module that works with Keystone authentication
to manage internal application security by behaving as a key manager.
bastion host Ans✓✓✓-Attached to the perimeter network and this host is the
main point of contact for incoming connections from the outside world.
Benefits of NFV Ans✓✓✓-Automating the orchestration and management lets an
NFVI be more scalable and achieve better resource utilization.
Using generic server hardware that can act as any number of network devices
instead of specialized hardware that perform singular functions helps reduce both
operational and capital expenditures.
virtualization offers carriers the ability to offer pay-as-you-go services without
huge up-front investment.
Avoiding proprietary hardware empowers administrators with a streamlined
provisioning process.
bridge Ans✓✓✓-A device that separates two or more network segments within
one logical network.
, Celiometer Ans✓✓✓-OpenStack module that monitors the NFVI and helps
identify bottlenecks and resource optimization opportunities.
centralized logging Ans✓✓✓-Individual hosts or networking devices send their
logs to a centralized logging service for log management and analysis.
Centralized logging interdependent services Ans✓✓✓-Collect logs
Transport
Store
Analyze
Alerting
Chef Ans✓✓✓-a configuration management tool written in Ruby and uses a pure
Ruby, domain-specific language (DSL) for writing system configuration "recipes"
These recipes which are grouped together and called a cookbook for easier
management, describe a series of resources in an optimal state
Cinder Ans✓✓✓-OpenStack module that provides block storage used as storage
volumes for VMs.
Clustering Ans✓✓✓-Adds a layer of defense against the controller being a single
point of failure by having one or more controllers in an active / standby scenario.
Command & Control (C&C) Ans✓✓✓-This implies that once a system is
compromised and / or infected, the system has to call home.
