(Choose two.)
A.
layer 3 support
B.
port security
C.
redundant components
D.
VLANs
E.
PoE
Which two characteristics describe the access layer of the hierarchical network design model?
Which two characteristics describe the access layer of the hierarchical network design model?

The correct answer is B and E
The access layer serves a number of functions, including
Layer 2 switching
High availability
Port security
QoS classification and marking and trust boundaries
Address Resolution Protocol (ARP) inspection
Virtual access control lists (VACLs)
Spanning tree
Power over Ethernet (PoE) and auxiliary VLANs for VoIP

This is a terrible question, the correct answer should be B, D, and E.
More like a trick question…
It provides POE and auxiliary VLANs… not actually POE itself… :/
They might change this question though.
This is a tough question. Should be B,D and E also according to this: http://www.ciscopath.com/content/61/.
However, in the 3-layer model, only port security and PoE are specifically of Access Layer, while VLANs span across the layers (and are used also on Distribution layer). So I agree with Grifter and would go too for B and E.
Trick question. But the key words are “Network Access Layer” which includes POE and VLANS
Wrote Cisco 100-101 exam last week, scored 985/1000! Around 8-10 new questions on NTP, Dynamic NAT, IPv6 and so on. SIMs: OSPF, Security, Configuration. I used the NEWEST 100-101 dumps from — http://www.passleader.com/100-101.html (238q, 100% valid!)
Hi Adam,
Can you say me which news questions are?
So data/phone/random VLANs are available to all access layer switches
Port security is feature that enable permit or deny traffic for end user PCs connected to access layer switch. Port security enable specify a group of valid MAC address on port. If maximum secure MAC address is reached then security violation modes lead to protect, restrict or shutdown of port.
There are 3 ways how to configure port security:
1) Static secure MAC addresses – manually configured with
switchport port-security mac-address MAC_ADDRESS
2) Dynamic secure MAC address – dynamic learned and stored only in address table (after restart cleared)
3) Sticky secure MAC address – mac address are learned dynamically and saved in running config (next can be merged with startup config).
