It is a broadcast IP address
Which two minimum parameters must be configured on an active interface to enable OSPFv2 to operate? (Choose two)
A.
OSPF area
B.
OSPF MD5 authentication key
C.
iPv6 address
D.
OSPf process ID
E.
OSPf stub flag
OSPF area
OSPf process ID
Which virtual MAC address is used by VRRP group 1?
A.
0050.0c05.ad81
B.
0007.c061.bc01
C.
0000.5E00.0101
D.
0500.3976.6401
0000.5E00.0101
Explanation: The virtual router MAC address associated with a virtual router is an IEEE
802 MAC Address in the following format:
00-00-5E-00-01-{VRID} (in hex in internet standard bit-order)
Which mode must be used to configure EtherChannel between two switches without using a negotiation protocol?
A.
on
B.
auto
C.
active
D.
desirable
on
Explanation: The Static Persistence (or “on” mode) bundles the links unconditionally and
no negotiation protocol is used. In this mode, neither PAgP nor LACP packets are sent or
received.
Refer to the exhibit.
How does the router manage traffic to 192.168.12.16?
A.
It selects the RIP route because it has the longest prefix inclusive of the destination
address.
B.
It chooses the OSPF route because it has the longest prefix inclusive of the destination address.
C.
it load-balances traffic between all three routes
D.
It chooses the EIGRP route because it has the lowest administrative distance
It selects the RIP route because it has the longest prefix inclusive of the destination
address.
Which device performs stateful inspection of traffic?
A.
firewall
B.
switch
C.
access point
D.
wireless controller
firewall
Refer to the exhibit.
What is the metric of the route to the 192.168.10.33/28 subnet?
A.
84
B.
110
C.
128
D.
192
E.
193
193
Which spanning-tree enhancement avoids the learning and listening states and
immediately places ports in the forwarding state?
A.
BPDUfilter
B.
PortFast
C.
Backbonefast
D.
BPDUguard
PortFast
Explanation: PortFast
Spanning Tree Portfast causes layer 2 switch interfaces to enter forwarding state
immediately, bypassing the listening and learning states. It should be used on ports connected directly to end hosts like servers or workstations. Note: If portfast isn’t enabled,
DHCP timeouts can occur while STP converges, causing more problems.

Refer to the exhibit.
If OSPF Is running on this network, how does Router2 handle traffic from Site B to
10.10.13.128/25 at Site A?
A.
It load-balances traffic out of Fa0/1 and Fa0/2.
B.
It is unreachable and discards the traffic.
C.
It sends packets out of interface FaO/2.
D.
It sends packets out of interface Fa0/1.
It is unreachable and discards the traffic.
Refer to the exhibit.
A network administrator must permit SSH access to remotely manage routers in a network.
The operations team resides on the 10.20.1.0/25 network. Which command will accomplish
this task?
A.
access-list 2699 permit udp 10.20.1.0 0.0.0.255
B.
no access-list 2699 deny tcp any 10.20.1.0 0.0.0.127 eq 22
C.
access-list 2699 permit tcp any 10.20.1.0 0.0.0.255 eq 22
D.
no access-list 2699 deny ip any 10.20.1.0 0.0.0.255
no access-list 2699 deny ip any 10.20.1.0 0.0.0.255
Explanation: Note : Already a statement is there in last to allow SSH Traffic for network
10.20.1.0 0.0.0.127, but Second statement says deny ip any 10.20.1.0 0.0.0.255, so how it
will work once it is denied. So the right answer is remove the -- no access-list 2699 deny ip
any 10.20.1.0 0.0.0.255.
