Q1. Which layer of the OSI model is responsible for logical addressing and routing between different networks?
  • A.  Data Link
  • B.  Network
  • C.  Transport
  • D.  Session
Show answer & explanation
✓ Answer: B. Network
The Network layer (Layer 3) handles logical addressing (IP addresses) and routing decisions between networks. The Data Link layer deals with physical/MAC addressing on a single link, while Transport handles end-to-end delivery and segmentation.
Q2. Which VLAN ID range is reserved as the normal range for VLANs configurable on a Cisco Catalyst switch running in VTP client or server mode with VTP version 2?
  • A.  1 to 1005
  • B.  1 to 4094
  • C.  0 to 1001
  • D.  2 to 4096
Show answer & explanation
✓ Answer: A. 1 to 1005
VTP versions 1 and 2 only propagate normal-range VLANs 1 to 1005; extended-range VLANs 1006-4094 must be configured locally and are not advertised by VTPv1/v2. VLAN 0 and 4095 are not usable, ruling out the other ranges.
Q3. A network engineer wants to summarize the networks 172.16.16.0/24 through 172.16.23.0/24 into a single route. Which summary address correctly represents this range?
  • A.  172.16.16.0/21
  • B.  172.16.16.0/22
  • C.  172.16.0.0/20
  • D.  172.16.16.0/23
Show answer & explanation
✓ Answer: A. 172.16.16.0/21
Networks 16 through 23 span 8 contiguous /24 blocks, and 8 blocks require borrowing 3 bits (2^3=8), giving a /21 mask. 172.16.16.0/21 covers exactly 172.16.16.0 to 172.16.23.255. A /22 only covers 4 blocks and a /20 would over-include networks outside the range.
