NO.4 Which Cisco IOS-XR command is used to unpack a package on the local router?
A. install boot
B. install commit
C. install add
D. install package
Answer: C
NO.5 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.
