NO.1 Refer to the exhibit.
Which statement about the private VLAN
configuration is true?
A. Only VLAN 503 will be the community PVLAN, because
multiple community PVLANs are not
allowed.
B. Users of VLANs 501 and 503
will be able to communicate.
C. VLAN 502 is a secondary VLAN.
D. VLAN 502
will be a standalone VLAN, because it is not associated with any other
VLANs.
Answer:
C

Explanation:
VLAN
502 has been configured as private-vlan community. So it is a secondary
PVLAN
NO.2 By default, all VLANs will belong to which MST instance when
using Multiple STP?
A. MST00
B. MST01
C. The last MST instance
configured
D. None
Answer: A
Cisco模試エンジン 642-813科目対策 642-813 642-813解答例 642-813ファンデーション
Explanation:
Recall
that the whole idea behind MST is the capability to map multiple VLANs to a
smaller number of
STP instances. Inside a region, the actual MST instances
(MSTIs) exist alongside the IST. Cisco
supports a maximum of 16 MSTIs in each
region. IST always exists as MSTI number 0, leaving MSTI 1
through 15
available for use. By default all VLANs are belonged to MST00
instance.
NO.3 CORRECT TEXT
Each of these vlans has one host each on
its ports
SVI on vlan 1 - ip 192.168.1.11 Switch B -Ports 3, 4 connected to
ports 3 and 4 on Switch A
Port 15 connected to Port on Router.
Tasks to
do:
1.Use non proprietary mode of aggregation with Switch B being the
initiator -- Use LACP with B being
in Active mode
2.Use non proprietary
trunking and no negotiation -- Use switchport mode trunk and switchport
trunk
encapsulation dot1q
3.Restrict only to the VLANs needed -- Use
either VTP pruning or allowed VLAN list. The preferred
method is using
allowed VLAN list
4.SVI on VLAN 1 with some ip and subnet
given
5.Configure switch A so that nodes other side of Router C are
accessible -- on switch A the default
gateway has to be configured.
6.Make
switch B the root

NO.4 Refer to the
exhibit.
From the configuration shown, what can be determined?
A. The
sticky addresses are only those manually configured MAC addresses enabled with
the sticky
keyword.
B. The remaining secure MAC addresses are learned
dynamically, converted to sticky secure MAC
addresses, and added to the
running configuration.
C. A voice VLAN is configured in this example, so port
security should be set for a maximum of 2.
D. A security violation restricts
the number of addresses to a maximum of 10 addresses per access
VLAN and
voice VLAN. The port is shut down if more than 10 devices per VLAN attempt to
access the
port.
Answer:
B
Cisco 642-813番号 642-813模試エンジン 642-813
Explanation:
By
enabling sticky port security, you can configure an interface to convert the
dynamic MAC
addresses to sticky secure MAC addresses and to add them to the
running configuration. You might
want to do this if you do not expect the
user to move to another port, and you want to avoid
statically configuring a
MAC address on every port. To enable sticky port security, enter
the
switchport port-security mac-address sticky command. When you enter this
command, the interface
converts all the dynamic secure MAC addresses,
including those that were dynamically learned
before sticky learning was
enabled, to sticky secure MAC addresses. The sticky secure MAC addresses
do
not automatically become part of the configuration file, which is the startup
configuration used
each time the switch restarts. If you save the running
config file to the configuration file, the interface
does not need to relearn
these addresses when the switch restarts. If you do not save
the
configuration, they are
lost.

NO.5 HOTSPOT
Answer:
Explanation:
Enable preempt on
the VLAN 101 HSRP group on DSW1 Issue the "show run" command and you can
see
that the "standby 1 preempt" configuration command is missing on DSW1. This is
needed for it to
become the active HSRP router immediately.
NO.6 Refer
to the exhibit.
HSRP has been configured and Link A is the primary route to
router R4. When Link A fails, router R2
(Link B) becomes the active router.
Which router will assume the active role when Link A becomes
operational
again?
A. The primary router R1 will reassume the active role when it comes
back online.
B. The standby router R2 will remain active and will forward the
active role to router R1 only in the
event of its own failure.
C. The
standby router R2 will remain active and will forward the active role to router
R1 only in the
event of Link B failure.
D. The third member of the HSRP
group, router R3, will take over the active role only in event of
router R2
failure.
Answer:
A
Cisco試験問題集 642-813最新版 642-813通信 642-813 642-813
Explanation:
When
Link A goes down, the HSRP priority value of R1 goes down to 95 (105-10) so R2
will be the
active router as it is using the default priority of 100. When
Link A comes back up, R1's priority is then
105 again and since pre-emption
is enabled, it will take back over the active role again.
NO.7 Which
three items are configured in MST configuration submode? (Select three)
A.
Region name
B. Configuration revision number
C. VLAN instance map
D.
IST STP BPDU hello timer
E. CST instance map
F. PVST+ instance

spanning-tree
mst configuration:
Use the spanning-tree mst configuration command to enter
the MST configuration submode. Use
the no form of this command to return to
the default MST configuration.
Defaults:
The default value for the MST
configuration is the default value for all its parameters:
Usage
Guidelines:
The MST configuration consists of three main
parameters:
NO.8 What is needed to verify that a newly implemented
security solution is performing as expected
?
A. a detailed physical and
logical topology
B. a cost analysis of the implemented solution
C.
detailed logs from the AAA and SNMP servers
D. results from audit testing of
