Topic Break Down
Topic 2, Layer 2 Technologies
Question No : 1 - (Topic 2)
Which three modes are valid for forming an EtherChannel between the ports of two switches?
(Choose three.)
A. Active/active
B. Active/passive
C. Passive/passive
D. Auto/auto
E. Auto/desirable
F. Desirable/on
Answer: A,B,E
Explanation:
To configure an EtherChannel using LACP negotiation, each side must be set to either active or passive; only interfaces configured in active mode will attempt to negotiate an EtherChannel. Passive interfaces merely respond to LACP requests. PAgP behaves the same, but its two modes are refered to as desirable and auto.
Question No : 2 - (Topic 2)
Which two statements about RSTP and MSTP BPDUs are true? (Choose two.)
A. MSTP switches can detect boundary ports when they receive RSTP version 2 BPDUs.
B. MSTP switches can detect boundary ports when they receive RSTP version 1 BPDUs.
C. RSTP switches can process MSTP version 3 BPDUs.
D. When all boundary switches are running RSTP, MST sends only version 0 configuration
BPDUs.
Answer: A,C
Question No : 3 - (Topic 2)
In which 802.1D port state are the root bridge, the root port, and the designated port(s) elected?
A. Listening
B. learning
C. forwarding
D. blocking
E. disabled
Answer: A
Topic 3, Layer 3 Technologies
Question No : 4 - (Topic 3)
What is the preferred method to improve neighbor loss detection in EIGRP?
A. EIGRP natively detects neighbor down immediately, and no additional feature or configuration is required.
B. BFD should be used on interfaces that support it for rapid neighbor loss detection.
C. Fast hellos (subsecond) are preferred for EIGRP, so that it learns rapidly through its own mechanisms.
D. Fast hellos (one-second hellos) are preferred for EIGRP, so that it learns rapidly through its own mechanisms.
Answer: B
