Which statement is true regarding the Junos OS?
A.
Each process runs in its own protected memory space ensuring that one process cannot
directly interfere with another.
B.
Processes share memory space but use separate ASICs so that one process cannot directly
interfere with another.
C.
A central processor called the IP2 Chip dynamically assigns memory as process needs
fluctuate.
D.
The memory management daemon (mmd) is responsible for allocating new memory for
processes as they request it.
Explanation:
Junos OS functionality is compartmentalized into multiple software processes.
Each process handles a portion of the device’s functionality. Each process runs
in its own protected memory space, ensuring that one process cannot directly
interfere with another. When a single process fails, the entire system does not
necessarily fail. This modularity also ensures that new features can be added
with less likelihood of breaking current functionality.
The Junos OS is the trusted, secure network operating system powering the
high-performance network infrastructure offered by Juniper Networks. The Junos
kernel is based on the FreeBSD UNIX operating system, which is an open-source
software system.
All platforms running the Junos OS use
the same software source code base
within their platform-specific images.
This design ensures that core features
work in a consistent manner across all
platforms running the Junos OS.
Because many features and services
are configured and managed the
same way, the setup tasks and
ongoing maintenance and operation
within your network are simplified.
