Q281. Refer to the exhibit.
Which option is the result of this configuration?
A. Devices in OSPF area 15 can reach the summary route 192.168.0.0/16 and its more specific subnets.
B. Devices in OSPF area 15 can reach only the more specific routes of 192.168.0.0/16.
C. Devices in OSPF area 0 can reach the summary route 192.168.0.0/16 and its more specific subnets.
D. Devices in OSPF area 0 can reach only the summary route of 192.168.0.0/16.
. area range
To consolidate and summarize routes at an area boundary, use the area range command in router configuration mode. To disable this function, use theno form of this command. Area area-id range ip-address mask [advertise | not-advertise] [cost cost] no area area-id range ip-address mask [advertise | not-advertise] [cost cost]
. Syntax Description
Identifier of the area about which routes are to be summarized. It can be specified as either a decimal value or as an IP address.
IP address mask.
(Optional) Sets the address range status to advertise and generates a Type 3 summary link-state advertisement (LSA).
(Optional) Sets the address range status to DoNotAdvertise. The Type 3 summary LSA is suppressed, and the component networks remain hidden from other networks.

Q282. Refer to the exhibit.
R1 and R2 both advertise 10.50.1.0/24 to R3 and R4 as shown. R1 is the primary path. Which path does traffic take from the R4 data center to the file server?
A. All traffic travels from R4 to R2 to the file server.
B. All traffic travels from R4 to R3 to R1 to the file server.
C. Traffic is load-balanced from R4 to R2 and R3. Traffic that is directed to R3 then continues to R1 to the file server. Traffic that is directed to R2 continues to the file server.
D. All traffic travels from R4 to R2 to R1 to the file server.
Q283. Which two statements about MLD are true? (Choose two.)
A. MLD is a subprotocol of ICMPv6.
B. When a single link supports multiple interfaces, only one interface is required to send MLD messages.
C. MLD is a subprotocol of PIMv6.
D. When a single link supports multiple interfaces, all supported interfaces are required to send MLD messages.
E. There are three subtypes of MLD query messages.
F. The code section in the MLD message is set to 1 by the sender and ignored by receivers.
Q284. Refer to the exhibit.
Which statement about the output is true?
A. The flow is an HTTPS connection to the router, which is initiated by 18.104.22.168.
B. The flow is an HTTP connection to the router, which is initiated by 22.214.171.124.
C. The flow is an HTTPS connection that is initiated by the router and that goes to 126.96.36.199.
D. The flow is an HTTP connection that is initiated by the router and that goes to 188.8.131.52.
We can see that the connection is initiated by the Source IP address shown as 184.108.40.206. We also see that the destination protocol (DstP) shows 01BB, which is in hex and translates to 443 in decimal. SSL/HTTPS uses port 443.
Q285. Which three statements about IPsec VTIs are true? (Choose three.)
A. IPsec sessions require static mapping to a physical interface.
B. They can send and receive multicast traffic.
C. They can send and receive traffic over multiple paths.
D. They support IP routing and ACLs.
E. They can send and receive unicast traffic.
F. They support stateful failover.
Q286. Which statement about VRRP is true?
A. It supports load balancing.
B. It can be configured with HSRP on a switch or switch stack.
C. It supports IPv4 and IPv6.
D. It supports encrypted authentication.
. You can configure both HSRP and VRRP on a switch or switch stack. However, you cannot add a switch model that supports only one protocol to a stack that is configured for both protocols.
. The VRRP implementation on the switch does not support the MIB specified in RFC 2787.
. The VRRP implementation on the switch supports only text -based authentication.
. The switch supports VRRP only for IPv4.

Q287. Which two Cisco IOS AAA features are available with the local database? (Choose two.)
A. command authorization
B. network access authorization
C. network accounting
D. network access authentication
Configuring the Local Database
This section describes how to manage users in the local database. You can use the local database for CLI access authentication, privileged mode authentication, command authorization, network access authentication, and VPN authentication and authorization. You cannot use the local database for network access authorization. The local database does not support accounting.

Q288. Which three statements about bridge assurance are true? (Choose three.)
A. Bridge assurance must be enabled on both ends of a link.
B. Bridge assurance can be enabled on one end of a link or on both ends.
C. Bridge assurance is enabled on STP point-to-point links only.
D. Bridge assurance is enabled on STP multipoint links only.
E. If a bridge assurance port fails to receive a BPDU after a timeout, the port is put into a blocking state.
F. If a bridge assurance port fails to receive a BPDU after a timeout, the port is put into an error disabled state.
Bridge Assurance is enabled by default and can only be disabled globally. Also, Bridge Assurance can be enabled only on spanning tree network ports that are point-to-point links.
Finally, both ends of the link must have Bridge Assurance enabled.
With Bridge Assurance enabled, BPDUs are sent out on all operational network ports, including alternate and backup ports, for each hello time period. If the port does not receive a BPDU for a specified period, the port moves into the blocking state and is not used in the root port calculation. Once that port receives a BPDU, it resumes the normal spanning tree transitions.
Q289. Refer to the exhibit.
Why is the neighbor relationship between R2 and R4 shown as ES-IS?
A. because there is an MTU mismatch between R2 and R4
B. because interface S3/0 of R4 is configured as L1/L2
C. because interface S3/0 of R2 is configured as L1
D. because there is a hello interval mismatch between R2 and R4
With IS-IS we will see ES-IS when one of the following is true:
So in this question because we do not know about the other sideâs âshow CLNS neighborâ A must be the better choose.
Q290. DRAG DROP
Drag and drop the extended ping command field on the left to its usage on the right.
