NEW QUESTION # 66
You have the networking configuration shown in the diagram. A pair of redundant Dedicated Interconnect connections (int-Igal and int-Iga2) terminate on the same Cloud Router The Interconnect connections terminate on two separate on-premises routers. You are advertising the same prefixes from the Border Gateway Protocol (BGP) sessions associated with the Dedicated Interconnect connections. You need to configure one connection as Active for both ingress and egress traffic. If the active Interconnect connection fails, you want the passive Interconnect connection to automatically begin routing all traffic Which two actions should you take to meet this requirement? (Choose Two)
- A. Configure the advertised route priority > 10,200 on the active Interconnect connection.
- B. Advertise a lower MED on the active Interconnect connection from the on-premises router
- C. Configure the advertised route priority as 200 for the BGP session associated With the passive Interconnect connection.
- D. Configure the advertised route priority as 200 for the BGP session associated Wlth the active Interconnect connection.
- E. Advertise a lower MED on the passive Interconnect connection from the on-premises router
Answer: B,D
Explanation:
This answer meets the requirement of configuring one connection as Active for both ingress and egress traffic, and enabling automatic failover to the passive connection in case of failure. The reason is:
The advertised route priority is a value that Cloud Router uses to set the route priority when advertising routes to your on-premises router. The lower the value, the higher the priority1. By setting the advertised route priority as 200 for the active connection, you ensure that it has a higher priority than the passive connection, which has the default value of 1001. This way, your on-premises router will prefer the routes from the active connection over the passive one for ingress traffic.
The MED (Multi-Exit Discriminator) is a value that your on-premises router uses to indicate its preference for receiving traffic from Cloud Router. The lower the value, the higher the preference2. By advertising a lower MED on the active connection from your on-premises router, you ensure that Cloud Router will prefer sending traffic to the active connection over the passive one for egress traffic.
If the active connection fails, Cloud Router will stop receiving routes from it and will start using the routes from the passive connection for egress traffic. Similarly, your on-premises router will stop receiving routes with priority 200 from the active connection and will start using the routes with priority 100 from the passive connection for ingress traffic. This achieves automatic failover without any manual intervention.
Option A is incorrect because setting the advertised route priority > 10,200 on the active connection would deprioritize it globally in your VPC network, which is not what you want1. Option B is incorrect because advertising a lower MED on the passive connection would make Cloud Router prefer sending traffic to it over the active one, which is not what you want2. Option D is incorrect because setting the advertised route priority as 200 for both connections would make them equally preferred by your on-premises router, which is not what you want1.

NEW QUESTION # 67
Your organization is deploying a single project for 3 separate departments. Two of these departments require network connectivity between each other, but the third department should remain in isolation. Your design should create separate network administrative domains between these departments. You want to minimize operational overhead.
How should you design the topology?
- A. Create 3 separate VPCs, and use Cloud VPN to establish connectivity between the two appropriate VPCs.
- B. Create 3 separate VPCs, and use VPC peering to establish connectivity between the two appropriate VPCs.
- C. Create a single project, and deploy specific firewall rules. Use network tags to isolate access between the departments.
Use Shared VPC to connect to a common VPC network. Resources in those projects can communicate with each other securely and efficiently across project boundaries using internal IPs. You can manage shared network resources, such as subnets, routes, and firewalls, from a central host project, enabling you to apply and enforce consistent network policies across the projects.
With Shared VPC and IAM controls, you can separate network administration from project administration. This separation helps you implement the principle of least privilege. For example, a centralized network team can administer the network without having any permissions into the participating projects. Similarly, the project admins can manage their project resources without any permissions to manipulate the shared network. - D. Create a Shared VPC Host Project and the respective Service Projects for each of the 3 separate departments.
Answer: D

- C. Create a VPC and request static external IP addresses from Google Cloud Assagn the IP addresses to the Compute Engine instances. Notify your customers of the new IP addresses so they can update their DNS
- D. Verify ownership of your IP addresses. After the verification, Google Cloud advertises and provisions the IP prefix for you_ Assign the IP addresses to the Compute Engine Instances
Answer: B
Explanation:
The correct answer is D because it allows you to use your own public IP addresses in Google Cloud without disrupting the platform or requiring your customers to update their DNS records. Option A is incorrect because it involves changing the IP addresses and notifying the customers, which can cause disruption and errors. Option B is incorrect because it does not use live migration, which is a feature that lets you control when Google starts advertising routes for your prefix. Option C is incorrect because it does not involve bringing your own IP addresses, but rather using Google-provided IP addresses.

NEW QUESTION # 74
Your company's logo is published as an image file across multiple websites that are hosted by your company You have implemented Cloud CDN, however, you want to improve the performance of the cache hit ratio associated with this image file. What should you do?
- A. Configure the default time to live (TTL) as O for the image file.
- B. Configure Cloud Storage as a custom origin backend to host the image file, and select multi-region as the location type
- C. Configure versioned IJRLs for each domain to serve users the *mage file before the cache entry expires
- D. Configure custom cache keys for the backend service that holds the image file, and clear the Host and Protocol checkboxes-
Answer: D
Explanation:
This answer meets the requirement of improving the performance of the cache hit ratio associated with the image file. The reason is:
Custom cache keys allow you to control which parts of the request URL are used to build the cache key. The cache key is a unique identifier that Cloud CDN uses to store and retrieve cached content1.
By default, Cloud CDN uses the complete request URL, including the protocol (http or https) and the host (the domain name), to build the cache key. This means that if the same image file is requested from different domains or protocols, Cloud CDN will cache multiple copies of it, which reduces the cache hit ratio1.
By clearing the Host and Protocol checkboxes, you can tell Cloud CDN to ignore these parts of the request URL when building the cache key. This way, Cloud CDN will cache only one copy of the image file, regardless of which domain or protocol it is requested from, which improves the cache hit ratio1.
Option B is incorrect because configuring Cloud Storage as a custom origin backend does not affect the cache hit ratio. It only affects how Cloud CDN retrieves the content from the origin if it is not cached. Option C is incorrect because configuring versioned URLs for each domain does not improve the cache hit ratio. It actually worsens it, because it creates more variations of the request URL that Cloud CDN has to cache separately. Option D is incorrect because configuring the default TTL as 0 for the image file means that Cloud CDN will not cache it at all, which defeats the purpose of using Cloud CDN.
