The Broadcast network type is the default for an OSPF enabled ethernet interface (while
Point-toPoint is the default OSPF network type for Serial interface with HDLC and PPP
encapsulation).

for the packet?
A.
209.165.200.254 via Serial0/0/1
B.
209.165.200.254 via Serial0/0/0
C.
209.165.200.246 via Serial0/1/0
D.
209.165.200.250 via Serial0/0/0
209.165.200.254 via Serial0/0/1

Which set of action satisfy the requirement for multifactor authentication?
A.
The user swipes a key fob, then clicks through an email link
B.
The user enters a user name and password, and then clicks a notification in an
authentication app on a mobile device
C.
The user enters a PIN into an RSA token, and then enters the displayed RSA key on a
login screen
D.
The user enters a user name and password and then re-enters the credentials on a
second screen
The user enters a user name and password, and then clicks a notification in an
authentication app on a mobile device
Explanation: This is an example of how two-factor authentication (2FA) works:1. The user
logs in to the website or service with their username and password.2. The password is
validated by an authentication server and, if correct, the user becomes eligible for the
second factor.3. The authentication server sends a unique code to the user’s second-factor
method (such as a smartphone app).4. The user confirms their identity by providing the
additional authentication for their second-factor method.
A user configured OSPF in a single area between two routers A serial interface connecting
R1 and R2 is running encapsulation PPP By default which OSPF network type is seen on
this interface when the user types show ip ospf interface on R1 or R2?
A.
port-to-multipoint
B.
broadcast
C.
point-to-point
D.
nonbroadcast
point-to-point
Explanation: The default OSPF network type for HDLC and PPP on Serial link is point-topoint
(while the default OSPF network type for Ethernet link is Broadcast).
Refer to the exhibit
An engineer configured the New York router with state routes that point to the Atlanta and
Washington sites. When command must be configured on the Atlanta and Washington

router?
A.

B.
ipv6 route 0/0 Serial 0/0/0
C.
ipv6 route ::/0 Serial 0/0/0
D.
ip route 0.0.0.0.0.0.0.0 Serial 0/0/0
E.
ipv6 route ::/0 2000::2
ipv6 route ::/0 Serial 0/0/0
