QUESTION 1
CRS-1 single shelf maximum capacities?
A. 320 Gbit/s
B. 640 Gbit/s
C. 1.2 Tbit/s
D. 92 Tbit/s
Correct Answer: C
1.4. SP high end product
1.4.05. CRS-1/3 structure
QUESTION 2
Which statement about Software Maintenance Upgrade is true?
A. CRS-1 SMU can be applied to a different platform, and vice versa.
B. SMU is an executable code for running a processor library that is shared between the different processes.
C. SMUs for each release are individually downloadable from Cisco.com and come in the form of a tarball.
D. SMUs provide software fixes for critical network down and qualification blocking issues. Therefore, every software
defect has a corresponding SMU.
E. SMUs are release-specific. If an issue affects multiple platforms or releases, an SMU is built separately for each
release and each platform.
Correct Answer: E
Explanation: 1.4. SP high-end product
SMUs for each release are individually downloadable from Cisco.com, whereas the bootable files and optional PIEs
come in the form of a tarball. SMUs are release specific. If an issue affects multiple platforms or releases, an SMU will
be
separately built for each release and each platform depending on the mission-critical need.
A CRS-1 SMU cannot be applied to a different platform, and vice versa. SMUs provide software fixes for the critical network-
down and qualification-blocking issues. Therefore, every software defect will not have a corresponding SMU.
QUESTION 3
In the context of GMPLS, LMP stands for:
A. Load Management Protocol
B. Label Management Protocol
C. Loop Management Protocol
D. Link Management Protocol
Correct Answer: D
The Generalized Multi-Protocol Label Switching (GMPLS)[1] is a protocol suite extending MPLS to manage further
classes of interfaces and switching technologies other than packet interfaces and switching, such as time division
multiplex,
layer-2 switch, wavelength switch and fiber-switch.
GMPLS is composed of three main protocols:
Resource Reservation Protocol with Traffic Engineering extensions (RSVP-TE) signaling protocol.[5][6]Open Shortest
Path First with Traffic Engineering extensions (OSPF-TE) routing protocol.[7][8] Link Management Protocol (LMP).[9]
QUESTION 4
Refer to the exhibit what is the status of the L2 tunnel between PE1, PE2 and the layer 2 switches?
A. The layer 2 tunnel is down due to the ACL is applied on the PE2 interface
B. The layer 2 tunnel is up and SW1 become the root bridge for VLAN 10
C. The layer 2 tunnel is down due to the MTU mismatch between SW1 and SW2
D. The layer 2 tunnel is up but no BPDUs are exchanged unless an extra configuration is applied
Correct Answer: B
QUESTION 5
What are the differences between LLQ and CBWFQ? (Choose two.)
A. LLQ priority queue bandwidth is policed with a congestion-aware policer.
B. With LLQ, bandwidth allocations for the priority queue and all the CBWFQ queues are configured using the priority
command.
C. LLQ does not support WFQ on the default traffic class (class-default).
D. LLQ supports the addition of strict priority queuing.
E. LLQ is configured using QMC and CBWFQ is configured using the fair-queue command.
Correct Answer: AD
