NO.8 Which Cisco
router platform supports running either the Cisco IOS or IOS XR operating
system?
A. Cisco CRS
B. Cisco ASR9k
C. Cisco ASR1K
D. Cisco
ISR-G2
E. Cisco 12000 GSR
Answer:
E
Explanation:
Explanation/Reference: The CRS-1 platform natively runs the
IOS XR operating system. The c12000
platform, originally being an IOS router,
can be upgraded to run IOS XR. However, c12000 hardware,
including line cards
(LC) as well as route processors (RP), must be checked for XR
compliance.
TURBOBOOT refers to a fresh boot of the router from ROMMON.
TURBOBOOT is required if an IOS
router is being converted to IOS XR or as a
last resort disaster recovery in the case of CRS-1. If the
router is already
running an IOS XR image, there is no need to TURBOBOOT the router for an
upgrade
or downgrade. Later sections in this chapter address the upgrade
scenario. This section deals with a
fresh boot of the router from ROMMON. A
new c12000 platform can be ordered prebaked as an IOS
XR router; however,
there will always be cases where an IOS running c12000 needs to install IOS
XR.
